Chapter 297

In front of everyone, Sun Yu prepared a little new gunpowder and then ignited it.

With a boom, the hot wind hit their faces, and there was a trace of numbness. The power of the new gunpowder was indeed huge, and it contained a bit of thunder power, and there was almost no smoke or dust.

After the demonstration, Sun Yu waited for everyone's comments. This is also an important part of the Tai Chu Palace's research; stones from other hills can be used to polish jade, and sometimes comments from laymen can also open up spiritual thoughts or help examine deficiencies.

Wei Yuan was slightly familiar with alchemy and medicine, and had nothing to say about the formula and physical properties; if he had to say something, he could only be like Xu Xu Wenwu, with just one "damn."

However, Wei Yuan's focus was on another aspect: the cost of the new gunpowder had increased by more than ten times.

The original gunpowder had already dropped to a few hundred catties per tael of immortal silver after mass production. And for the new gunpowder, Wei Yuan estimated that I fear one tael of immortal silver could only buy five catties.

After watching Sun Yu's demonstration, Yu Yu Zhizhuo said: "If you pursue instantaneous power, there is still some room for improvement. These gunpowder can be refined like this..."

Yu Yu Zhizhuo grabbed a handful of new gunpowder and turned it into round particles as fine as sand under magic power; the particles were loose inside and not solid. Testing it again, the power increased by twenty percent out of thin air.

Sun Yu added: "Now this formula can still be improved in two directions: one is to improve the quality of Thunder Sand, Inch Gold Charcoal, and Fire Glue, which can increase the power, and further, Mysterious Thunder Stone can be used to replace Thunder Sand, so the power will be greater. Another direction is to move closer to the original formula, which can get cheaper gunpowder; what is the best combination between power and price still requires a lot of testing."

Wei Yuan breathed a sigh of relief; several previous wars showed that the number of fire guns was the key to turning the tide of the war. This kind of thing naturally lacks power; if it is few and refined, it is not as good as strong people directly casting Dao arts to bombard.

Wei Yuan was now exceptionally sensitive to the control of the war situation. The key to fire guns changing the war was to allow mortals to go to the battlefield and have the power to fight. This was a move that fundamentally turned the tide of the war.

If it weren't for fire guns, there would be less than 20,000 combat-capable people among the 100,000 population of the realm. And with fire guns, this number would exceed 100,000. With fire guns and "Momentary All Living Beings," Wei Yuan would have 100,000 elites in a short time. Without "Momentary All Living Beings," there would also be 100,000 ordinary soldiers.

Ordinary people, ordinary diet, Body-Muscle Realm needs at least two or three years, archers need an additional three years of training, sword and shield soldiers only need half a year shorter, and only spear soldiers are the simplest, needing one year of training.

But training a steel pipe gunner only takes three days, or half an hour if in a hurry. Steel pipe guns can shoot a piece the size of a door panel ten zhang away, just aim roughly in the direction, there is no point in aiming.

The new gunpowder was full of power, and the cultivators were very excited, their spiritual thoughts surging, giving many opinions, and in an hour, they discussed many directions for improvement.

For example, Yu Yu Zhizhuo proposed that Mysterious Thunder Stone could be replaced by Thunder-Struck Parasol Tree. There was a thunder tree in the realm; placing the phoenix-blood parasol tree next to the thunder tree and accepting the baptism of thunder day and night could become a Thunder-Struck Parasol Tree in half a year. Its physical properties were slightly weaker than Mysterious Thunder Stone, but the price was only one-tenth of Mysterious Thunder Stone.

Finally, determining the best ratio of the formula seemed to have no good method, and could only be tested bit by bit. Previously, Sun Yu divided every portion of raw materials into ten small portions, and then tested them bit by bit, for example, eight parts Thunder Sand to one part Inch Gold Charcoal; eight parts Thunder Sand to two parts Inch Charcoal... relying on this stupid method, he finally had this ratio after testing more than 1,700 times.

Wei Yuan finally understood why he had already assigned more than ten people to Sun Yu, and he was still calling for a lack of manpower.

Speaking of this, Sun Yu said to Ji Ji Liuli: "Senior Sister Ji, I fear I will need to borrow your Demon-Suppressing Pagoda for a while to save me some effort."

Ji Ji Liuli's Demon-Suppressing Pagoda also had the ability to derive heavenly secrets. The two discussed for a long time, and Ji Ji Liuli set up an array on the spot, placing the Demon-Suppressing Pagoda in the middle. Half of the spiritual objects she used to set up the array were exchanged by Wei Yuan, and Wei Yuan couldn't always let her pay for it herself to subsidize him.

Under the Demon-Suppressing Pagoda, Sun Yu simulated the physical properties of several raw materials with magic power and sent them into the array. The two constantly adjusted the array, and after tossing for half a day, a burst of fire finally rose under the Demon-Suppressing Pagoda, and the raw materials simulated by Sun Yu's magic power burned!

Although it was not yet an explosion, after Ji Ji Liuli looked at it carefully, she said: "It has eighty percent of the charm of real burning; this method is feasible!"

Looking at the greatly excited Sun Yu, Ji Ji Liuli added: "For renting the pagoda, one thousand taels of immortal silver per hour."

Unknowingly, the sky was already bright.

The cultivators dispersed, each having breakfast or doing morning lessons. Wei Yuan wanted to leave, but was pulled by Yu Yu Zhizhuo: "Where is the Realm Lord going?"

Wei Yuan struggled uselessly: "I'm going to read..."

Yu Yu Zhizhuo dragged Wei Yuan away: "There is a golden house in the underground, and there is a jade beauty in the underground. Realm Lord, I just found some good-looking things underground, let's go see them."

Two hours later, Wei Yuan didn't see anything good-looking, but saw another 1,000,000 catties of various ores.

Yu Yu Zhizhuo smiled broadly, while directing the cultivators to install pillars and crossbeams in the tunnels opened by Wei Yuan, and praised: "After Junior Nephew advanced, your Dao power soared, and even if my ten or so junior brothers added together, they wouldn't be as good as you alone. It's a pity that you are busy, so I can only block you from time to time."

Wei Yuan's heart stirred, manifesting a faceless warrior, and said: "How about this one?"

A halo of light appeared in front of the faceless warrior, with the same "Rapid Water Blade Art," but the power was not high, only equivalent to a full-strength strike of an ordinary human-rank cultivator, but it could also cut rocks.

After Wei Yuan advanced to the mid-stage of Dao Foundation, the range of Dao arts that these faceless warriors could use also improved. Originally, it was just a simple water flow technique, but now there were water blades inside, finally becoming a real "Rapid Water Blade Art."

The faceless warrior's water flow was continuous, digging into the rock layer bit by bit.

Originally, Yu Yu Zhizhuo frowned, but after a cup of tea, his expression was somewhat solemn, after a stick of incense, his face was surprised, and after two sticks of incense, he was already shocked.

An ordinary human-rank cultivator casting Dao arts like this would exhaust their Dao power in a cup of tea, and an earth-rank cultivator could support it for a stick of incense; if it were two sticks of incense, an earth-rank cultivator might even die of exhaustion. "Junior Nephew, how long can this puppet spell last?"

Wei Yuan said: "From morning to night."

Afterward, he condensed a point of light and handed it to Yu Yu Zhizhuo: "This is the control heart formula."

Yu Yu Zhizhuo accepted the heart formula and tested it simply. The faceless warrior stopped the Dao art at his command, walked to the other side, and continued digging. Yu Yu Zhizhuo was still somewhat hesitant, and two more faceless warriors appeared in front of him.

"There are two more here, I'll leave them to Senior Uncle together," Wei Yuan said.

A smile bloomed on Yu Yu Zhizhuo's face, and he patted Wei Yuan hard: "Go about your business!"

Three puppet cultivators who could work from morning to night were much more useful than Wei Yuan, who came and went and didn't know when he could be pulled over. From now on, Yu Yu Zhizhuo could plan the underground excavation as a whole, and the progress would advance by leaps and bounds; only the most difficult sections would need Wei Yuan.

For Wei Yuan, the Dao power he naturally recovered every moment was equivalent to three human-rank Dao Foundation cultivators, so these three faceless warriors working from morning to night meant Wei Yuan's own Dao power neither increased nor decreased.

Wei Yuan said: "By the way, Senior Uncle, adjust the output slightly later; take one-third of every three parts of iron and copper to build various tools."

"Good, follow me, I'll show you another good thing."

Wei Yuan saw Yu Yu Zhizhuo heading all the way up, and finally breathed a sigh of relief that the good thing was not deep underground. Speaking of which, he admired this Yu Senior Uncle; he could stay underground for more than ten hours a day, and rock veins were more attractive to him than peerless beauties.

!.

The two returned to the ground all the way, and Yu Yu Zhizhuo took Wei Yuan to his private workshop.

There were actually seven different arrays set up inside this small courtyard, with more than a dozen various anvils, workbenches, etc., and hundreds of tools, with thirty-odd hammers of all sizes alone, the smallest like ants, and the largest weighing several thousand catties. All the hammers were at least high-grade magic treasures, and even two were magic treasures.

Yu Yu Zhizhuo solemnly took out a steel pipe flashing with ghostly blue light, handed it to Wei Yuan, and laughed: "To build this thing, I put in quite a few of my private collections."

Wei Yuan took it and observed it carefully. This steel pipe was six feet long, hollow inside, open at both ends, with an inner diameter about the size of an egg, and the whole thing was about the thickness of a teacup. Wei Yuan was tall and strong, and it was just right to hold it.

This steel pipe faintly revealed a ghostly cold aura; it was actually a supreme magic treasure, and although it looked unremarkable, it actually weighed more than seven hundred catties, and Wei Yuan had to use some strength to use it freely.

Yu Yu Zhizhuo took out a long and a short gun tip, and installed them at both ends to form a short gun.

"Originally, I reserved openings at both ends to prepare for possible rear-loading ammunition in the future. However, Sun Yu came up with new gunpowder, so many ideas could be realized. Let me show you the original concept first."

Yu Yu Zhizhuo moved out a box, inside which were gunpowder sealed with oil paper. The sealed gunpowder was one foot long, and all were identical in size, thickness, and length.

Yu Yu Zhizhuo took Wei Yuan to the shooting range, took the steel pipe, installed the gun tail, and said: "The characteristics of this gun are three: indestructible, frost, and dust-free."

Wei Yuan could understand indestructible and frost; one was an upgrade of sturdiness, and the other could prevent the gun body from overheating and being damaged, protecting the gun body array, and at the same time could add frost power to the attack, making the opponent's movements sluggish. But what was going on with "dust-free"? Wasn't this common on Daoist robes? Robes with this characteristic basically didn't need to be washed, and at the same time could avoid poison and gu.

However, Wei Yuan thought deeper, and had doubts about frost. This kind of steel pipe gun basically had to be used as a stick after one shot, and at most it could be re-installed with a gun head to be an ordinary long gun, so whether the gun body was hot or not didn't matter at all.

Yu Yu Zhizhuo had an expression of "I knew you kid didn't understand," and took out another box, which was actually a box of gun heads.

Yu Yu Zhizhuo reached out and pressed virtually, and five sections of gunpowder and one gun head flew out automatically, the gunpowder columns entered the gun barrel from the front end one after another, and then the gun head arrived automatically. Yu Yu Zhizhuo held the long gun and pointed directly at a stone target dozens of zhang away.

In the roar, the stone target wearing mid-grade magic treasure armor, with defense equivalent to an earth-rank cultivator, was pierced by one shot!

Yu Yu Zhizhuo didn't stop, but gave a loud shout, and all the gunpowder and gun heads flew up, automatically arranged neatly, and then loaded and fired, loaded and fired, the roar connected into a piece, and in the blink of an eye, more than ten shots were fired, blasting half of a giant rock wrapped in steel plates.

Seeing this, Wei Yuan finally realized that the use of "dust-free" was to make loading smooth! Uncle Yu was unrestrained and was truly a great talent.

This round of rapid fire just now, converted according to the standards of the world outside the sky, the rate of fire per minute had already exceeded 500 rounds, which was a standard machine gun.

This front-loading single-shot machine gun had never appeared in the world outside the sky.

Yu Yu Zhizhuo handed the gun in his hand to Wei Yuan and said: "This gun is a supreme magic treasure, already not inferior to the magic swords used by Xiang Xiaoyu and Cui Yu, and I named it 'Pure Land of No Filth,' so I'll give it to you. However, now that there is new gunpowder, I have to re-make some medicine bags, and the amount of medicine has to be reconsidered, but in total, the power will increase again. But no matter how full the medicine is, this gun can handle it."

Wei Yuan took the "Pure Land of No Filth," secretly thinking that this name didn't mean sending people to reincarnation?

With this gun in hand, killing earth foundations was like killing dogs, and heaven foundations couldn't withstand a round of salvos; it was truly a weapon for group battles.

Wei Yuan held the gun, feeling heroic, but also somewhat helpless; even without this gun, he was now killing earth foundations like killing dogs.
