Chapter 214: Capital Lecture Hall and Imperial Academy of Sciences

My True Neglect of Proper Work, Chapter 225: Capital Lecture Hall and Imperial Academy of Sciences. Wang Chonggu supervised the construction of the Great Ming Imperial Palace, the Buddhist pagoda, and the Imperial Academy of Sciences.

And the first to be completed was the Imperial Academy of Sciences, because the Academy involved neither the Emperor nor the Empress Dowager, so it naturally built much faster.

And for this Academy, Zhang Juzheng specially requested to build a newspaper to collect news of the Great Ming Dynasty's technological progress.

After the pillars of the Meridian Gate were poured, it was discovered that there was a place that had not been poured properly, so the pillar had to be chiseled down and rebuilt entirely. But the Academy didn't need to be like that. If there was a place that wasn't poured properly, just find an old man to smear it.

After Zhu Yijun learned of this, he immediately stopped Wang Chonggu's wasteful behavior. "It's fine as it is. The structural strength is completely sufficient. There's no need to be overly critical. Anyway, once it's plastered, nothing will be seen."

Wang Chonggu pondered repeatedly and followed the holy decree, but he discussed with the Ministry of Works how to pour the pillars without seams, which became Wang Chonggu's main work recently.

The Imperial Academy of Sciences was built the fastest. Zhu Yijun affirmed Wang Chonggu's work and decided to go see it personally tomorrow.

The patrolling capital camp military censor Lin Jingyang submitted a statement on five matters. The five matters were actually one matter: how to get military wages into the hands of the soldiers, especially the capital camp.

Tan Lun sat up straight and said with a heavy expression: "In the twenty-ninth year of Jiajing, Altan invaded. The Great Ming capital camp was all old, weak, sick, and disabled, unable to fight. The Prince of Dingxiang, Zhu Xixiao, was in charge of the defense of the nine gates. No matter who was sent to fight, the soldiers cried and hesitated to move. It has been twenty-eight years since then, and the capital camp has been slightly revitalized."

"The Great Ming clearly suffered such a big loss? Why not reorganize the military camp?"

"Is it that the Shizong Emperor and the late Emperor didn't know the capital camp was important? Naturally, they were very clear. The Shizong Emperor tried to revitalize the capital camp several times and rebuilt it multiple times, and the late Emperor asked multiple times. But when Your Majesty ascended the throne, there were only five or six thousand old, weak, sick, and disabled soldiers."

"Because the capital camp must be paid. If the border army is owed, it's owed. If they make a fuss about wages, they just make a fuss in the border area. But if the capital camp makes a fuss about wages, it's not as simple as just making a fuss."

Tan Lun discussed a problem: why had the combat effectiveness of the capital camp been so weak since the Chenghua years, but no one had ever wanted to solve it?

After the capital camp was disbanded during the Tianshun years, it was reorganized during the Chenghua years. The weakness of the capital camp, besides the general trend of valuing literature and devaluing martial arts, was also because the imperial court's fiscal situation could not sustain it, leading to the capital camp becoming increasingly weak.

Any decree that does not mention cost makes the cost exorbitant. The capital camp was a typical example of this.

The biggest problem with the capital camp's weak combat effectiveness was that there was no money. The second biggest problem was that the officers drank the soldiers' blood. The third problem was food.

One needed to find a way to raise enough military wages to pay the soldiers. This was the biggest difficulty. And at present, there was no such trouble. From the Emperor to the court ministers, the Great Ming was full of experts in gathering wealth and profiting. If you have rice in your hand, even if you call the chickens, they won't come. The first thing Zhang Juzheng solved when he was in power was the administration, and then the fiscal problem.

The second problem in maintaining the capital camp was the problem discussed by the military censor Lin Jingyang: how to distribute the money.

"Lin loves the country's intention to revitalize." Zhu Yijun closed Lin Jingyang's memorial and said with great appreciation.

Lin Jingyang said in his memorial that the most effective way was to pay wages in advance.

The wages for this month should be paid in full on the first day. This month's time was the time for reporting grievances. If it hadn't reached their hands by the third day, they could go to the Ministry of War and the Five Military Commissions to report. Once verified, the Ministry of War would lead, and the Censorate and the Ministry of Revenue would audit the wages.

If you don't want to be pestered by civil officials, don't deduct the soldiers' wages and don't let the soldiers make a fuss.

"Lin's idea is very good, but if the imperial court's silver is not available, it will be difficult to implement. Better forget it." Qi Jiguang put forward his own thoughts.

This idea of paying wages in advance was truly too good. The difference between paying before and after was a huge gap. The capital troops directly became the group that led all classes in the Great Ming. Even the officials were paid the current month's salary in the following month, while the soldiers received the current month's wages on the first day.

But the imperial court's silver would be unavailable due to urgent needs. If it couldn't be withdrawn, it might lead to a disaster.

Qi Jiguang naturally hoped so, but he didn't like this becoming the straw that broke the capital camp. The wind of public opinion in the Great Ming that valued literature and devalued martial arts still existed, and the public's suspicion of a strong military still existed. It seemed that as long as one cultivated literary virtue, one could stabilize the border, especially after Altan's enfeoffment in the northwest. This wind of public opinion that cultivated literary virtue to soothe the distant people was rampant.

Therefore, Qi Jiguang very much wanted to ask for this honor for the Great Ming capital troops, but he also knew that Your Majesty had already borne enough pressure to expand the army. Fortunately, the Daning Guard was taken, and the white clay of Taotu Mountain was found, so the capital camp finally proved its value.

Qi Jiguang was never someone who asked for too much. It was already very good now.

Expanding the army was a topic that had never been mentioned since the Xiaozong Emperor's reign, especially expanding the capital camp.

Zhu Yijun heard Qi Jiguang's suggestion and immediately said: "General Qi's worry is very good. I deeply agree. Feng Da, the inner treasury must set aside six months of wages for the capital camp to prevent the national treasury from being unable to pay wages."

The national treasury had many places to spend money, especially when disasters like droughts, locusts, floods, and earthquakes occurred. The imperial court had to allocate silver for relief. If there was a time when it wasn't available, the inner treasury, as an emergency reserve fund, would come in handy.

Six months was 1.3 million taels of silver. That is to say, from now on, there would be 1.3 million taels of silver in the palace that could not be moved at will and had to be left for the capital camp to pay wages.

When Wang Guoguang heard Your Majesty say this, he immediately bowed and said: "Your Majesty, the Senior Grand Secretary consulted me specifically when he submitted a joint memorial with the court ministers to expand the capital camp. The national treasury has money."

Your Majesty was still young. The Prince of Lu needed his capping ceremony, needed to be enfeoffed, and needed to get married. Your Majesty also needed to get married. The child's pocket money could just be spent by himself.

In the twelfth month of the first year of Wanli, the Empress Dowager issued a strict edict to the Cabinet, questioning Zhang Juzheng for being harsh to the Emperor. Zhang Juzheng was terrified.

The little Emperor felt the purple robe was fading and became a green robe, directly skipping the fading process, only wearing the green robe. The green robe color was long-lasting and bright. Zhu Yijun still liked the Great Ming's green color. The purple robe color was too heavy, and wearing clothes of an old person at a young age was really not very suitable. As a result, the Empress Dowager learned that the palace did not dye purple robes and asked if it was due to frugality, and was furious, questioning the Cabinet why they were treating the Emperor poorly, and the words were severe.

After Zhu Yijun heard this, he ran to explain to the Empress Dowager what was going on.

The Great Ming national treasury, besides 15% of the tax revenue being divided for the Emperor, also had 1.2 million taels of gold flower silver and various 50-50 split annual revenues. The little Emperor was definitely not short of money now. But aiming at the child's pocket money—should Wang Guoguang still be the Minister of Revenue? If the Empress Dowager heard this, she would probably feel again that the ministers were treating Your Majesty poorly.

Wang Guoguang had to consider the political influence.

"Indeed, Your Majesty, our Great Ming has money now." Wang Chonggu couldn't help but straighten his chest. The military supplies for the capital camp, besides being given to the capital camp from the profits of the Great Ming woolen official factory, still had a surplus.

"Feng Da?" Zhu Yijun looked at Feng Bao and said.

"Your subject obeys the decree." Feng Bao didn't talk nonsense and directly accepted the decree.

"The inner treasury and national treasury have been borrowing from each other for so many years. This life has only passed for a year or so. In the second year of Wanli, the national treasury borrowed a sum from the inner treasury, but it was only paid back in the third year of Wanli." Zhu Yijun looked at Wang Guoguang and Wang Chonggu and said with a smile: "This money is still in the palace, just to prevent the national treasury from having no wages to pay, so it can be used for emergencies."

"Last year, the capital camp soldiers pushed war chariots into the city. On the war chariots were cannons and muskets, not long and short weapons, bows, crossbows, and arrows, but coal. Hanging a small sign on it, it said eight *wen* a *jin*. Wherever they went, they shook bells, and the people in the neighborhood tentatively went to buy it and found that they could really buy it, and they were overjoyed."

When Zhu Yijun said this, he immediately rippled with a smile. When he saw that scene, Zhu Yijun was laughing, and when he thought of it, he was also laughing, sunny and bright.

This was Zhu Yijun's heartfelt smile. Report to the Son of Heaven above, save the common people below—Qi Jiguang said so, did so, and carried out military construction so. The Great Ming capital troops were worth it.

This was the reason Zhu Yijun did so.

"Sir, I heard that powerful gentry can get a horse plaque from the government office. With this horse plaque, even if one doesn't have an official position, one can stay in post stations, use post carriages, and use post soldiers. Can it really be done like this?" Zhu Yijun looked at Zhang Juzheng and asked.

Zhang Juzheng bowed and said: "Returning to Your Majesty, it is indeed possible. Your subject began to travel around in the thirty-third year of Jiajing. At that time, your subject had an official position and could receive a horse plaque to travel around. But your subject didn't do that. My family had a little thin wealth, so I didn't take this advantage. But what Your Majesty said is indeed done by such people, and there are many."

"What else is this horse plaque used for?" Zhu Yijun's expression became serious when he heard Zhang Juzheng's answer.

Zhang Juzheng continued: "It can conscript people for corvée labor. Shoulder-carrying and lifting things can all be done by taking the horse plaque to make poor commoners and laborers work. If staying overnight, taking the horse plaque can make the people make fire and cook for them. Firewood, rice, oil, and salt are all people's property, and the people fear officials like they fear tigers."

"Your subject has witnessed it personally."

The travelogues of the Great Ming scholars were all about taking horse plaques, using post stations for free, using poor commoners and laborers for free, and then writing about it in a refined way.

Zhang Juzheng had witnessed it many times. Many relatives of officials were very good at taking advantage of the imperial court. The Great Ming's sturdy body was hollowed out little by little like this.

"Why is it possible? Just by taking a horse plaque, one can order the Great Ming people around?" Zhu Yijun continued to ask.

Zhang Juzheng bowed again and said: "Because the horse plaque represents that he is a person of the imperial court."

"Therefore, I said the capital army is precious. The capital army is also a person of the imperial court, but under General Qi's supervision, 'bandits passing are like combing, soldiers passing are like raking, officials passing are like shaving.' The Great Ming soldiers not only didn't plunder the people but could also do something for the people. I am very gratified." Zhu Yijun explained why he wanted to set up an emergency reserve fund specifically for paying wages.

Because it was worth it.

This dialogue between the Emperor and Zhang Juzheng made the court ministers all silent. Everyone clearly realized that the capital camp led by Qi Jiguang had a completely different significance from the Emperor's personal guards of past dynasties.

Its military construction program was to save the common people, and it had truly done so.

"Paying wages in advance and inner treasury emergency matters—I have already decided. No more discussion." Zhu Yijun finally concluded.

"Your Majesty is wise." Zhang Juzheng bowed, singing praises with a sincere heart. This was truly wise. With this emergency reserve fund, the capital camp would be more stable.

The ministers hurriedly stood up and shouted in unison: "Your Majesty is wise."

"In the memorial, Lin proposed to organize a Lecture Hall to specifically train junior officers. These junior officers are trained by the imperial court, not someone's family slaves. In this way, the matter of paying wages to the capital camp will not be like before, where 18 taels of silver were paid out, and only eight *qian* of silver remained." Zhu Yijun mentioned the second suggestion proposed by Lin Jingyang.

The Lecture Hall was specifically for training junior officers and command officers, that is, grassroots military officers.

In Lin Jingyang's view, the Great Ming army could drink soldiers' blood layer by layer, and it had a great relationship with these junior officers of the capital camp. Grassroots military officers were all family members of various assistant regional commanders. Wasn't that drinking however they wanted?

The imperial court training junior officers became especially important.

And training junior officers required money, grain, and people.

"It should be organized." Zhang Juzheng first answered Your Majesty's question and then looked at Yu Dayou.

The imperial court had money, grain was not very scarce, and the Great Ming had people: the old but ambitious Yu Dayou.

Yu Dayou was already old and could no longer run ships, and couldn't bear the bumping on the ship. But he went to the northwest with Qi Jiguang last time to prevent the rebellion of Zhang Siwen's party. Yu Dayou was in the capital, and with the Dissection Institute and the Imperial Hospital, his health was still considered healthy.

As for this first libationer, Yu Dayou was the only choice.

The selection of junior officers was also very simple: select soldiers with merit from the elite soldiers and have them study at the Lecture Hall.

Of course, the Emperor was undoubtedly the principal. The president of the academy, in name, could only be Your Majesty. The *jinshi* candidates were the Son of Heaven's students, so these junior officers should also be the Son of Heaven's students.

Tan Lun also looked at Yu Dayou and said with a smile: "General Yu, can you still teach the young men?"

"There is nothing impossible." Yu Dayou nodded very seriously.

Yu Dayou lived in Fujian and had no appointment. When he wrote to Tan Lun, Yu Dayou was 69 years old. To show that he could still fight, he said he was 69 and could still make women pregnant, expressing that he could still lead troops.

He was full of hot blood and full of martial strategy, but he couldn't display it. This was the most suffocating place in his life. Now, he was old and couldn't fight, but he could still serve the country. For him, this was the best destination.

Zhu Yijun looked at Yu Dayou and said: "General Yu, please work hard for the country again."

"It is a great honor." Yu Dayou stood up to accept the order. He agreed with organizing the Lecture Hall and hoped even more that he could still serve the Great Ming. Moreover, he had compiled a military book, "Summary of Military Classics," specifically summarizing leading troops to fight. This was the textbook prepared for the junior officers.

After Zhu Yijun dealt with the military censor's memorial, the court discussion continued to follow the process.

The inventor of the lottery method for appointing and dismissing officials, Sun Piyang, who was sent out to be an official, requested retirement due to illness. The court discussion passed his resignation memorial. The reason was very simple: Sun Piyang couldn't do this job. The Baoding Viceroy had one more job than other viceroys, which was to concurrently manage the Yellow River waterways in the jurisdiction.

Just this one thing made Sun Piyang exhausted. If the embankment broke, he was afraid he would be executed, so he could only retire.

The Liaodong patrolling censor Hou Yuzhao submitted five matters for land reclamation: first, equalize fields; second, set tax examples; third, strictly limit approval; fourth, supervise collection on time; fifth, expand reclamation. Equalizing fields was to distribute reclaimed fields to the people who reclaimed them, mainly to attract people to go to the Daning Guard and Liaodong to reclaim fields, set a good tax ratio, and not change it again, and strictly execute the Examination Law, not allowing arbitrary additions. Due to rainfall, farming in Liaodong was already difficult, and if there were more additions, there would be even fewer people, etc.

The Minister of Revenue Wang Guoguang felt it was feasible and asked Hou Yuzhao to write a book on land reclamation to share his practical experience in land reclamation, to be used for the Great Ming Liaodong land reclamation affairs.

The land reclamation theory of the Baoqi Department could not be copied in Liaodong. Hou Yuzhao was a loyal minister who combined practice and reclaimed fields bit by bit. Building soil camps was something Xu Zhenming had not mentioned.

The environment in Liaodong was far harsher than in the hinterland, and the experience of Hou Yuzhao, this land reclamation expert, became precious.

The Ministry of Rites discussed the ritual for the Prince of Lu's capping ceremony. They were going to give Zhu Yilou a capping ceremony. From then on, Zhu Yilou would no longer be a yellow-mouthed child. He not only had to wear a hat but also study. What was added was the leather cap with nine tassels, which was the treatment of a Prince of the Blood.

Zhu Yijun felt a headache when he saw this long ritual, but seeing that it was Zhu Yilou who was suffering, he directly approved it.

Before Zhu Yijun had a son, the Prince of Lu, Zhu Yilou, was the substantial Crown Prince. Before the Crown Prince was established, most of the Emperor's brothers were in the capital, not enfeoffed in the local area, waiting until the Crown Prince was determined before being enfeoffed.

For example, the Prince of Xiang, Zhu Zhanji, who acted as regent, the Jingtai Emperor Zhu Qiyu, and the Chongzhen Emperor Zhu Youjian, were all based on this background, waiting in the capital for the Crown Prince position to be determined before being enfeoffed in the local area.

When the Longqing Emperor was still the Prince of Yu, he competed for the Crown Prince position with his younger brother, the Prince of Jing. And the Prince of Jing, Zhu Zaizhen, had no children after his marriage in the thirty-first year of Jiajing. After being married for several years without children, the Prince of Jing fell into a natural disadvantage. Finally, the Prince of Jing was enfeoffed, and the Prince of Yu ascended the throne.

The Prince of Jing's mansion was also abolished because the Prince of Jing had no sons.

Therefore, Hai Rui said that Xu Jie had no merit of following the dragon. The Prince of Jing had no sons, which destined the Prince of Jing to be unable to seize the throne. So, after it was determined that the Prince of Jing could not have children, the Prince of Yu was the only successor. Where did Xu Jie's merit of following the dragon come from?

"The two-Guang Viceroy Governor Ling Yunyi sent a victory report. Luzon Regional Commander Zhang Yuanxun and Guangxi Regional Commander Li Xi led ten battalions of troops, advancing step by step, steadily and surely. After four months, they surrounded Mount Luopang, pacified the Luopang civil unrest, beheaded 16,000-plus people, and accepted the surrender of 23,000-plus people. They requested to abolish the Tusi, establish Dong'an and Xining counties, and build Luoding Prefecture, implying that the Luopang Yao unrest had been pacified." Zhang Juzheng submitted a victory report, the content of which was the end of the two-Guang civil unrest.

To win this battle, Governor Ling Yunyi specially invited Zhang Yuanxun, who was in Luzon, to return to the two-Guang to preside over the war situation.

The Luopang civil unrest, pacified and then rebelled, pacified and then rebelled, repeatedly, had lasted for nearly a hundred years. This time, it finally came to an end. The Tusi was abolished, and the establishment of Luoding Prefecture meant that the Yao civil unrest in Guangdong had come to an end.

According to old customs, Governor Ling Yunyi was granted a second-rank python robe and added as Vice Minister of the Ministry of War.

"Governor Ling Yunyi submitted a memorial saying: 'Settling the people lies in settling down and working happily.' Therefore, he earnestly requested the imperial court to allow the Yao people in the two-Guang to cut wood and sell it to Guangzhou Prefecture to stabilize the Yao people." Zhang Juzheng explained in detail the "Law of Settling People and Working Happily" in Governor Ling Yunyi's memorial.

It was very similar to the salt law of Governor Yin Zhengmao initially. It was to find a way for the Yao people to make a living. Cutting wood, although very tiring, was quite profitable now. At least the Guangzhou shipyard bought wood every year.

After cutting wood, one could reclaim wasteland and farm. These were all matters of the people's livelihood.

Before Governor Ling Yunyi fought Mount Luopang, these matters had also gone through court discussion.

The main content of the court discussion was that the Earl of Yingyang, Zhang Yuanxun, wanted to return to Luzon, but Governor Ling Yunyi didn't want Zhang Yuanxun to go back. The imperial court had successively transferred Chen Lin, Governor Yin Zhengmao, and Deng Zilong away from the two-Guang. If Zhang Yuanxun left again, Governor Ling Yunyi would have to borrow people from Luzon to fight a battle. Whether to borrow or not depended on the face of the National Father.

The conclusion of the court discussion was that the Earl of Yingyang, Zhang Yuanxun, still had to return to Luzon.

The reason was also very simple: the two-Guang could easily transfer troops from the interior, but Luzon could not.

Now with the Maritime Patrol Inspection Department, maritime patrol inspections, and hydrofoil sailboats, sending messages from Guangzhou Prefecture to Songjiang Prefecture only took three days. When the Bohai Sea was not frozen, matters reported from the two-Guang only needed five days to be sent to the Northern Yamen.

Even if the Bohai Sea was frozen, landing from Jiaozhou and entering Shandong to be sent to the capital only took eight or nine days.

Therefore, Governor Ling Yunyi's request could only be rejected by the imperial court, and Zhang Yuanxun was still transferred back to Luzon.

"How about transferring Governor Ling Yunyi to Shandong to be the Viceroy? Isn't Governor Ling Yunyi good at killing?" Zhu Yijun proposed an idea before the court discussion ended.

Shandong needed to find someone good at killing to see whether the neck was hard or the knife was hard.

Zhang Juzheng bowed and said: "Your Majesty, Mount Luopang has just been pacified. Viceroy Ling should still be the Viceroy in the two-Guang to settle the soldiers and people. Otherwise, the Yao people might rebel again."

"No rush." Zhu Yijun said with a smile.

The court discussion ended. Zhu Yijun led the court ministers to the Imperial Academy of Sciences. The other half of the Great Dalongxing Temple was also going to be demolished to build the Lecture Hall. The Buddhist pagoda and the four rooms nearby became the entirety of the Great Dalongxing Temple.

Zhu Yijun's carriage stopped steadily in front of the Academy. Royal Uncle Zhu Zaiyu had been waiting for a long time. Seeing the Emperor's carriage, he led a group of Academy and Mingli Hall officials to pay respects.

Zhu Yijun got off the jade carriage, looked at the five vermilion characters "Imperial Academy of Sciences" on the plaque, and nodded with great satisfaction. This was written by his own hand. The reason the Academy was called the Imperial Academy of Sciences was because the Imperial Academy of Sciences was exclusively sponsored and built by the little Emperor.

Zhu Yijun walked into the Academy of Physical Sciences. After entering, there was a very spacious, square-shaped corridor. In the very center stood a piece of reclining stone, one person tall and over two zhang long, engraved with: 【To act is to be one; to be sincere is all there is — Zhu Zhongxing】

These three characters were taught to the little Emperor by Zhang Juzheng. Although most Confucian scholars said that this "one" was benevolence, Zhang Juzheng believed that this "one" was truth.

Zhang Juzheng taught it this way and did it this way.

Zhu Zhongxing was never just Zhu Yijun's pen name, but a collection of all expectations for the Great Ming's revitalization. Zhang Juzheng clearly had the qualifications to use this pen name to publish any article in the miscellaneous newspaper.

The Academy was decorated with lanterns and colorful streamers, full of joy.

"Is that the Sutra Repository?" Zhu Yijun pointed to the highest building in the entire Academy, the six-story Sutra Repository. This was originally the place where the Great Dalongxing Temple stored sutras. Later, after the Great Dalongxing Temple fell into disrepair, the books were all stolen. Later, when the imperial court built it, they tidied it up and it became a book storage building. The official name of this building was Tianyi Building.

It's just that the books stored inside now were not sutras, but books on the principles of all things.

Zhu Yijun had always thought that the Tianyi Building was made of wood. Walking closer and knocking on the pillar, he discovered that this thing was veneered, and the inside was built with lime-poured reinforced concrete. It's just that the architectural style was similar to the original.

Zhu Yijun stood in front of the Sutra Building, looked at the windows, and said with great surprise: "Glass windows?"

"Glass windows," Wang Chonggu bowed and said.

Zhu Yijun refused to go in for a long time. The glass had a light green color, which was especially obvious in the sunlight. This was the inevitable result of no magnetic separation and no high-quality quartz ore. Zhu Yijun's telescope could naturally be burned with natural crystal, but others couldn't.

Even with a bit of green, it was enough to attract attention. At least the light in the room was extremely bright.

The frame of the window was all wood, and one could smell a faint smell of tung oil.

"Good, good, good." Zhu Yijun stepped into the Sutra Repository of the Academy. What entered his eyes were rows of bookshelves. And Zhu Zaiyu walked in front of everyone and said with a smile: "This Tianyi Building has nine studies, each study has twelve departments, each department has fourteen bookshelves, totaling 180,000 volumes. Your subject is still organizing them."

Every bookshelf was made of iron, and the bookshelves were all locked. Books could indeed be borrowed here, but many were unique copies. The purpose of locking them was not to prevent theft, but to prevent fire.

Storing books in iron boxes was to fear that if one place caught fire, the whole building would be burned down.

Zhu Yijun walked past these iron book cabinets step by step, occasionally opening them to look. The nine studies were: Mathematics, Agriculture and Sericulture, Astronomy and Calendar, Metallurgy and Casting, Essence Extraction, Geography, Boats and Vehicles, Painting, and Military Affairs.

Mostly, things that the Confucian study halls would not collect were collected here. Some were pulled by Zhu Zaiyu from the Prince of Zheng's mansion, and some were purchased from the people by the Academy's supervisor.

Essence Extraction was actually grain processing, which was food processing. Boats and Vehicles were ship and vehicle design. Painting was dyes, and Military Affairs was military equipment manufacturing.

For example, this category of Boats and Vehicles was divided into twelve departments, mainly the twelve main steps of boat and vehicle construction, studying by subject and researching separately.

Zhu Yijun took out a "Tung Oil Illustration" and read it with great interest. It recorded ginger slices for anti-freezing, sealing tung oil barrels, etc., which could effectively increase the storage time of tung oil.

And Military Affairs recorded the construction methods of various Great Ming military equipment. Among them, Zhu Yijun saw the Qi family cannon cart.

The Qi family cannon cart placed the cannon on a steel frame, and then lifted the steel frame to lock it on the support frame, which could change the pitch angle of the cannon muzzle. There were rails under the steel frame, which could achieve rotation within a 90-degree range.

The Qi family cannon cart was a name given by Zhu Yijun. Qi Jiguang originally called it the "Revitalizing Martial Cannon Cart," specifically

However, after Qi Jiguang's practical testing, it was found that even on a rainy day, it could only fire one shot; reloading for a second shot would be somewhat difficult. But it is excellent for preventing gunpowder from becoming damp during marches.

The Zhenwu artillery carriage allows cannons to move from fixed positions onto the open battlefield.

Without realizing it, Zhu Yijun had reached the sixth floor. Looking at everything in the Academy of Physical Sciences, he felt ambitious.

This place is the engine of the New Policies, continuously injecting power into the Great Ming's New Policies.

Hand over all the monthly tickets in your hands! If you don't hand them over, they'll expire, hey!!! Begging for monthly tickets, Awoo!!!!!!!
