"Semi-finished product?" Yan Liben said curiously.

"Fuel is a big problem. The reason why I was able to send people to heaven last time was that I used a lot of fuel, and the height was not satisfactory. As long as the fuel problem was solved, I might be able to send people to heaven."

Listening to Li Chunfeng's words, Yan Liben said: "If outsiders think these drawings are really not understood."

Li Chunfeng said: "In fact, as long as you calculate the relationship between lift, gravity, weight, and area, you may be able to find out how much fuel you need in total, but this kind of fuel is not easy to find."

Yan Liben twitched bitterly and said, "Master Li Chunfeng, I will ask more questions about how far your level of mathematics has reached."

Li Chunfeng smiled ashamedly, sighed and said, "It's better not to mention it, but I'm just touching some fur with mathematics."

Yan Liben said in confusion: "All the Central Plains mathematics is, you, Li Chunfeng, are also unique."

Li Chunfeng shook his head and said, "I thought so before, but I saw more knowledge of mathematics in Jingyang. I used to be arrogant and you also know the skills of the big bull. If you want to talk about some aspects of mathematics, even the big bull is almost beyond my understanding."

Seeing Yan Liben confused, Li Chunfeng took a drawing from the wall, "This is the drawing of the pump, and what is recorded on it is the experimental data."

Yan Liben saw the dense formulas on the drawings and said in surprise: "Is this what ordinary people can learn?"

Li Chunfeng shook his head and said, "Of course not. Most people can make it by following the drawings. The reason why they use these drawings is because Daniu needs these formulas when doing theories."

Just looking at these formulas, Yan Liben had sweat on his forehead without realizing it.

Li Chunfeng sighed and said, "I have been studying mathematics for half my life, but the more I learn it, the more I feel that there is no end to the mathematics. Perhaps what I am now mastering is just some of the basics of mathematics."

Yan Liben no longer looked at these drawings, "You and I are the same. You can spend all your life hard for math, but I am the same."

The children came to the academy one after another, and it became lively here.

Yan Liben said: "It is rumored that all the people who came from Li Zheng's religion are monsters."

Li Chunfeng shook his head, "Where are there monsters? When our perception reaches a height that they can't understand, they will think that we are monsters. People in the world are prejudiced. When you are different from many people, they either assimilate them or get rid of you."

These words made Yan Liben silent.

Li Chunfeng said: "It's a cruel statement, right? But that's how Li Zheng was treated before."

Jingyang's plan to recruit apprentices is still continuing.

Early in the morning, Li Zheng was still cleaning the horse ring.

Li Tai ran away and said: "Li Zheng, what's wrong with you?"

Seeing the anxious look, Li Zheng said, "I forgot to tell you that Yan Liben entered the academy."

Li Tai said: "Actually, Chu Suiliang and I have had this idea for a long time, but it would be easier for you to invite someone."

The topic turned back, and Li Tai looked at Li Zheng's appearance, "Li Zheng, are you eating something dirty?"

Seeing Li Zheng pushing a truck of fodder, Li Tai said, "You not only recruit apprentices, but you also give away money for free?"

Li Zheng poured the forage into the manger and said, "It's true."

Li Tai looked at Li Zheng strangely, "I used to think you are a stingy person and love money, but now you are sending the money directly?"

Picking up the broom, Li Zheng was still sweating profusely when he started cleaning the horse ring.

Li Tai said relentlessly: "If you have more money, it would be great to give it to me directly."

Li Zheng said helplessly: "That is to recruit better talents, a means to attract talents."

Li Tai said curiously: "Do we Jingyang lack talents?"

Li Zheng said: "Of course, there is a shortage. Naturally, the more talents the better, and our productivity in Jingyang has reached a bottleneck period."

After thinking about the reason, Li Tai unconsciously took a breath, "Bottleneck period?"

Li Zheng wiped his sweat and said, "In fact, it is difficult for our Jingyang to improve productivity. A person in the workshop can make ten goods a day. Even if he adds one hundred people, he will have ten goods per person. From the perspective of cost and profit, it means no growth. This is the bottleneck of productivity."

Li Tai thought silently.

Li Zheng said again: "Just like we have transformed the printing workshop and changed the printing method, the same manpower and material resources can produce several times the previous paper, which is the improvement of productivity."

Li Tai nodded thoughtfully, "I understand a little bit. In fact, it is just a very simple mathematical problem. The conditions for the big ones are derived from the big ones, but the calculation method is still the same, is it still difficult, right?"

The son nodded as if he was teaching, and Li Zheng said, "It seems that His Highness the King of Wei is not too stupid either."

Seeing Li Zheng's appearance, Li Tai still looked suspicious, "It sounds like this, but why do I feel like you are half of it and keep half of it? You must have something not said, right?"

Li Zheng said: "You will understand in the future."

As he said that, Li Zheng handed Li Tai a broom and said, "I've come here, help me clean the horse circle."

After taking the broom, Li Tai looked at the situation in the horse circle and said, "You ask my dignified King of Wei to sweep the horse circle for you?"

Li Zheng said, "I won't sweep you, right? I'll let your father send you to the fiefdom."

Li Tai gritted his teeth and said, "Are you threatening me?"

Li Zheng said: "Li Chengqian must hope that his people will take over your position."

As soon as he finished speaking, Li Tai said quickly: "Just just sweep the horse ring, I'll do it!"

Li Tai entered the horse circle without saying a word and began to clean the horse manure.

He might be willing to let Li Tai leave the academy and go to the fiefdom, but Li Tai would definitely not want to let Li Chengqian's people enter the horse circle.

The relationship between Li Tai and Li Chengqian has reached a point where water and fire are incompatible.

For Li Tai, the fat man, no matter how bad his fate is, Li Chengqian cannot be made to live a better life.

There are more and more people outside Jingyang Village, and these people are here to interview apprentices.

There are even many old craftsmen who come to Jingyang.

For a time, the threshold for taking the exam was raised to a higher level.

The more people come, the greater the sensation it causes.

Wang Ding hurriedly came to report Li Shimin's current situation in Jingyang.

Li Shimin smiled bitterly and said, "Li Zheng raised his arms and shouted so many people responded."

Wang Ding said: "It is said that Jingyang's conditions are too good. Many people don't want to make the money they have. They learn skills from this. After all, for craftsmen, where can they find good things that can learn skills and money to get."

Looking at Li Shimin's eyes, Wang Ding said again: "I have also seen many people from the Ministry of Works."

Li Shimin's eyes immediately changed, "Do he dare to touch my Ministry of Works?"
