After listening to the third uncle's answer, Chen Zhengtai looked clear!

"That's it." Chen Zhengtai smiled and said, "The paper has not started to be mass-produced, and the printing workshops... have not started to operate externally for the time being, and the land is still tight. These can make huge profits in the future, and even white salt may not be possible to continue to increase profits. Compared with these, what does this merely increase cost of more than a thousand chunks of money count?"

"But..." The third uncle could not have dreamed that one day the Chen family would be able to earn a gold pound every day, but he still felt distressed, so he couldn't help but say with a bitter face: "But this is also money..."

"Don't worry, third uncle." Chen Zhengtai said mysteriously: "In terms of seniority, you are my uncle, but when it comes to making money, I say something I shouldn't say, you are my grandson... Ah... I should silence. But you, wait and see. It won't take long to see the wealth in Guanzhong will be automatically sent to our Chen family like a snowball. I still think the cost of hiring workers is too low, but... well, everything has to be done step by step. It's better to wait until it comes naturally. If it is to pull the seedlings to help grow, it will be bad. There is another thing... Then General Cheng Yaojin, don't make things difficult for him anymore. I heard that he is going to chop you with an axe. Third uncle, nephew is very worried about your safety. You must take care of yourself."

Chen Zhengtai said it sincerely, and his eyes were filled with worry about his third uncle!

When the third uncle heard this, he burst into tears and wiped his tears and said, "Yes, yes, my family is the most filial. As for Cheng Yaojin, will I be afraid of him? Let him come over! Humph, don't look at it. My nephew is the disciple of the emperor, and my grandson is the duty service of the disciple."

Chen Zhengtai didn't expect that his third uncle was so tough, but he still persuaded him. He knew that his third uncle was a rooster. He would never give up if he could take advantage of others. He couldn't even pull the cow back! He couldn't help but sigh that his third uncle is a talent and he will use it well in the future.

As for the third uncle, he still doesn't understand. Now that the cost of hiring workers in the Chen family is increasing, why is he still swearing to make a fortune?

It's really puzzling.

It can be seen that Chen Zhengtai’s mysterious appearance made Uncle San feel much more at ease!

He has seen enough of this nephew's ability. If you don't believe him, who do you believe?

Soon, the admissions examination at Erpigou University was about to begin.

The exam is actually very simple, and it is the most basic knowledge of literacy and digitization and arithmetic.

The Chen family has long distributed textbooks to local households, allowing them to study by themselves. Once they can pass the exam, they can get three kilograms of fine grain per month. In addition... there are also admission places to join the junior class of the university.

In addition to these self-taught common people, they were the first wealthy and merchants who purchased land here and settled.

There are not many people who settle down, only dozens of households.

Because the requirements for settlement are too complicated, many people's enthusiasm is immediately wiped out. In fact, most of these people have choices and may not have to be in Erpigou University. Except for some who really can't discipline their children, they bit the bullet and get the household registration process. Most of them retreated in the face of difficulties.

Li Yifu, Hao Chujun and others were also invited back to the school. Although they passed the Jinshi, the imperial court has not yet officially been awarded official positions. Anyway, they are idle and they always have to use it.

Of course, as soon as Chen Zhengtai said, they all came to report without hesitation!

So they were arranged to continue copying textbooks.

At first, everyone copied it well, but the more they continued, the more they felt it became incredible.

Because the contents later have begun to deviate from their understanding of things, and various strange symbols, especially many mathematical formulas, make them feel very novel and puzzling.

But they are different from others.

Being able to pass the Jinshi is because they have wisdom that ordinary people do not have.

The most important thing is that the textbook is copied one by one, and it is easy to start and then difficult to copy. In the process of copying, I already have some skills. The more I copied it, I felt a little awkward and difficult to understand, but I gradually realized something.

Li Yifu copied a mathematical formula, and actually paused his pen. Then he looked for a piece of white paper with suspicion, lowered his head and calculated something, and calculated for a long time... Finally, among the dense drafts, he exclaimed: "This formula is really amazing."

Hao Chujun and others on the side were attracted by the exclamation and looked at each other curiously: "Brother Li Xian is..."

Li Yifu looked a little excited and said with a gaze: "It's so amazing. You only need to apply this formula. In just a moment, you can calculate a large amount of calculations. Brothers, look..."

As he said that, his eyes were so excited that they shone with light from this major discovery.

People in the Tang Dynasty were not opposed to mathematics. After all... even the imperial examinations had special math exams. Among the six arts of gentlemen, they included "ritual, music, archery, calligraphy, and number". Although this last "number", although interpreted by later Neo-Confucianists as the study of principle, number or qi, it seemed very impressive!

But in fact, if this number is just the science of qi numbers, but is ranked after the knowledge of archery and driving, it is obviously unreasonable.

In this era, no one will deny the help of mathematics to people. After all... In this era, it is important to manage the family and govern the country and pacify the world. Whether it is managing the family and govern the country, it is closely related to arithmetic. If you are not even proficient in arithmetic, you will become a loser? You don’t understand the principle of living within your means. What family do you own and what country do you manage?

Chinese literature is ordinary to Li Yifu, but the interesting thing about Chinese literature is that it uses a large amount of spoken language to teach, not what scholars advocate.

Mathematics is too powerful, even causing Li Yifu to kneel down.

"My teacher is really talented. How did he think of these?" Li Yifu sighed again.

The other eight people thought about it. Ask me, how can we know? Do we open the head of our mentor and take a look?

When... they began to copy physics and chemistry, the difficulty of learning began to increase.

At this time... the nine people are no longer copying books, but more often they are thinking while copying.

In fact, if they get something like this awkward and difficult to understand, they will definitely disdain to take care of it.

But... this is what the teacher has. According to their understanding of the teacher, the teacher is an unfathomable person. Since the teacher is unfathomable, everything he does must have a deep meaning. Since it has a deep meaning, it is worth thinking and researching.

It's not serious, it's not important. Once I've tried it, I feel a chill on my back.

So later, they had no intention of copying it. After copying a sentence, they had to pause and think.

Sometimes Chen Zhengtai would come and see them one by one, so he would be angry!

Please come and give you food and drink. What are you thinking about? You will be punished and copied three times.

The nine people were locked in Minglun Hall like this, and they were copying and thinking about eating and sleeping.

Many knowledge seemed difficult to understand in the eyes of the Tang Dynasty, but Li Yifu and Hao Chujun discovered many mysteries.

"Look at this mathematics, physics, oh, and chemistry, have you not understood it yet? The great thing about this book is that it is easy first and then difficult, and gradually progresses. For example, if you understand the first lesson, you can understand the second lesson roughly. If you understand the second lesson, you will have a look at this third lesson. The teacher's book looks complicated, but as long as you follow this rule and understand it bit by bit, the knowledge you will be able to come to fruition. I don't know how much thought you have spent here."

The more Li Yifu talked about it, the more he became more energetic, and the more he talked about it, the more he felt that learning these things was of great significance!

He has copied it seven or eight times, and now he has gained a lot of experience. Although he has not understood many textbooks thoroughly, he is now slowly starting to master the rules!

He was originally a very smart person and was good at learning from one example. "But... what's the use of learning this? I know mathematics. Recently, I have made great progress in arithmetics. I think the same is true for all my seniors. But what makes me unable to see through is physics and chemistry. What is the use of physics and chemistry? "

Hao Chujun is a very arrogant person, but now... he actually said: "The teacher must have a reason for his mentor to do this. I have mastered the rules now. Any teacher's things are treasures. He seems to be just teaching us to copy books. On the surface, he seems to want to save some manual expenses for copying, but I vaguely feel that he wants to take this opportunity to sharpen us well. His mind is really unpredictable, but we will never teach us to suffer losses if we do what he said. Have you forgotten? Looking back at the beginning, we couldn't understand why the teacher summoned us to the school! But it was not until we were in high school that we knew... the teacher used unknown methods to improve our knowledge so that we could do it in high school."

Everyone nodded, and couldn't help but show a little admiration. The body and mind that were already exhausted were also greatly encouraged. They seemed to feel that... the mentor became more and more unfathomable, and had reached a level of shocking!

Gao Zhizhou coughed: "Instead of speculating on the thoughts of our mentors here, it is better to copy them well. I have copied them every day for more than ten days and have memorized physics. However, although I can memorize them like a stream, many of them are still not understood, but this doesn't matter. I believe that as long as I understand them slowly, I will definitely understand the mystery."

"We have been given today by our teacher. Now, our teacher has given us a great opportunity. If we don't seize it, we will be unbearable."

"It's extreme."
