Chapter 188: How Much Silver Does It Take to Do These Things

That day, Yun Shu brought over some strange gadgets again.

Inside one of the large crates was, surprisingly, a flush toilet!

Yan Ning had long known that Yun Shu wanted a flush toilet, but she hadn't expected his obsession to be so deep that he actually made one.

Yan Ning asked, "You intend to set this up? But, setting up a modern toilet is very troublesome."

Yun Shu sighed: "This is just a concept; if we build a sewage drainage system and then a tap water system, it will be much more convenient, and we could even have things like showers."

Yun Shu did the math again and said to her: "A few million taels would solve it, and Jianyue Pavilion has a monthly turnover of tens of thousands."

Yan Ning was also somewhat tempted.

Although building a railway currently costs a lot of money, a sewage drainage system is also very important.

The next morning, Yun Shu went to court again.

Behind him he carried a large wooden crate, not knowing what he had invented this time.

At this time, Yun Shu was a Second Rank Official, and standing at the front, he was very conspicuous.

Yan Ze asked: "What good thing have you made again?"

Yun Shu opened the lid: "A flush toilet; one flush after using the latrine is enough, it is very convenient."

Yan Ze's eyes lit up immediately, "Can these be mass-produced?"

Yun Shu felt there was a chance, so he hurriedly said: "They can, and different sizes can be customized."

Yun Shu also explained to the ministers what this toilet was for and how to use it.

In short, it was one word: convenient and fast.

The Minister of Personnel was the first to support his own son: "I think they can be mass-produced; it would be convenient for everyone."

Even the usually stingy Minister of Revenue expressed his agreement.

At this moment, someone raised a question: "Where will the dirty things be flushed to?"

Yun Shu revealed a smile: "That is what I wanted to say; I think if we build a sewage drainage system in the Capital and a tap water system, our quality of life will improve significantly."

At this moment, the court fell silent.

Only the stingy Minister of Revenue asked: "How much silver will it take to do all this?"

Yun Shu pondered for a moment, "If we install everything, five million taels of silver should be enough."

Everyone's eyes widened.

The Minister of Revenue's voice was trembling: "Do, do you know how many things five million taels of silver can do?"

Yun Shu nodded: "I know, but this sewage system is really worth doing."

The Minister of Revenue firmly disagreed: "How many railways could five million taels of silver build? And you are actually thinking about flush toilets?"

Yan Ning immediately stood out, "This is what you said, oh; if this five million taels isn't used on building sewage pipes, then let's use this five million silver to build the railway."

The Minister of Revenue almost couldn't catch his breath.

Soon, Yan Ning said to them: "However, the sewage pipes must also be built, but since money is needed everywhere right now, let's wait and see next year."

The Minister of Revenue sighed, "That is fine; too much money was spent this year, let's see if there is enough next year."

Seeing them relent, Yun Shu also let out a long sigh of relief.

If this group of ancient people had insisted on using their original chamber pots, he would have had no way to push this project forward.

That day, Yun Shu came to the Eastern Palace again.

He asked Yan Ning familiarly: "Your Highness, what is the Daxia dynasty currently lacking? Everything I wanted to do recently has been done, and for a moment, I have no next plan."

Yan Ning thought for a long while and asked casually: "How about making an airplane? Or a hot air balloon, let me think... can plastic be made?"

Yun Shu said: "It can be made, but, Your Highness, what do you need plastic for?"

Yan Ning said: "Plastic can make many things, such as electric fans, as well as water pipes; there should be other uses."

Yun Shu pondered for a moment, then rose to take his leave.

Indeed, he had to hurry and make the plastic, lest the sewage pipes end up being unusable.

Walking to the door, Yun Shu seemed to think of something and said to Yan Ning: "Your Highness, the conditions here are difficult; the plastic made might not be suitable for holding food."

Yan Ning said: "That is no matter; if it is made, it will certainly have its uses."

Upon returning, Yun Shu immersed himself in the laboratory to make plastic.

Fortunately, this time he didn't cause too much of a stir, such as blowing up the laboratory.

Yun Shu scoured through chemistry books, some papers, and videos from other transmigrators.

He finally found the method for making plastic.

At the Research Institute, there was a place specifically for Yun Shu to work; usually, when he did experiments, he would close the doors and windows tightly because sometimes he had to take out his iPad to take a look.

Every time this happened, Song Yu and Jiang Zhi would not come in.

Yun Shu was busy as a bee here, but he didn't forget to assign tasks to the two of them; since they were officials, they had to work hard.

Yun Shu wrote down the general data and shape of the airplane and had them calculate it.

After Yun Shu finished tinkering with the plastic, he went to research the airplane with Song Yu and Jiang Zhi; they had already finished all the fine details.

In just a few days, a miniature airplane was finished.

Yun Shu took the airplane and went with Song Yu and Jiang Zhi to find Yan Ning.

Seeing the airplane in his hand, Yan Ning asked somewhat uncertainly: "You made an airplane toy?"

Seeing that the material of this airplane was made of plastic, she hadn't expected him to have made the plastic so quickly.

Yun Shu shook his head: "It is a scale-model airplane."

As he spoke, Yun Shu prepared to demonstrate it for her.

He took a white mouse out of his fastened pocket and had Song Yu and Jiang Zhi tie the mouse into the seat.

Yan Ning's eyelids twitched as she watched, and she silently stepped back two paces.

After tying the mouse on, Yun Shu adjusted the data, and the airplane took off very quickly.

The mouse squeaked incessantly, as if it were extremely terrified.

The small airplane flew forward for several hundred meters, nearly flying past the palace walls.

Yun Shu smiled radiantly and asked, "What does His Highness think of this airplane?"

A look of joy also appeared on Yan Ning's face: "It's quite good. Can it be mass-produced? How long can it fly if a person sits inside?"

Yun Shu said, "For now, we can only look at the model for fun. To actually build an airplane, we would need aluminum alloy, which hasn't been developed yet."

Yan Ning felt somewhat regretful.

However, there were some things that simply could not be made in ancient times; it was not a problem that could be solved by just her and Yun Shu alone.

She still had to cultivate scientific research personnel.

Yan Ning looked at Song Yu and Jiang Zhi, feeling very satisfied; with two more people, perhaps she could have them work on some simple projects.

Perhaps seeing the regret in her eyes, Yun Shu said, "We can use wood, but it just won't be able to fly for too long or too high."

Yan Ning felt a sense of anticipation.

Yun Shu retrieved the airplane and asked, "I'll gift this scaled-down airplane to His Highness."

Yan Ning took a step back, "There's no need to gift the mouse as well."

Over the next few days, when Yan Ning brought the airplane to her father, he acted as if he had discovered a new continent and wanted to play with it every day.

Yan Ze asked, "Can a wooden airplane really be made?"

Yan Ning nodded, "It should be possible; the earliest airplanes were all made of wood."

Yan Ze was somewhat skeptical.

He prepared to go find Yun Shu.

Who would have thought that before he even left the palace gate, he saw palace maids and Eunuchs rushing over in a hurry.
