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

"That's it." Chen Zhengtai smiled and said: "Now the paper has not yet started mass production, and the printing workshop ...... For the time being, there is no external operation, there is still land sales, and now the land is still tight, these can have huge profits in the future, and even white salt, may not be without the possibility of continuing to increase profits. Compared with these, what is the added cost of more than 1,000 yuan? ”

"But......" The third uncle actually never dreamed that the Chen family would be able to enter the gold bucket one day, but he was still distressed, so he couldn't help but say with a bitter face: "But this is also money......

"Third uncle, don't worry." Chen Zhengtai said mysteriously: "When it comes to seniority, you are my uncle, but when it comes to making money, I say something that shouldn't be said, you are my grandson...... Ahh......h I should slap my mouth. But you old man wait and see, it won't be long before the wealth in this level will be automatically sent to our Chen family like a snowball. I don't think the cost of hiring a worker is too low, but ...... Anyway, everything must come step by step, and wait until the water is a matter of course, if the seedlings are pulled out to help grow, it is not good. One more thing...... That Cheng bites General Jin Cheng's side, don't make it difficult for him anymore, I heard that he is going to use an ax to chop you, third uncle, nephew is very worried about your safety, you must take care of yourself. ”

Chen Zhengtai said very sincerely, and his eyes were full of worry about the third uncle!

When the third uncle heard this, he burst into tears, wiped his tears and said: "Yes, yes, my family Zhengtai is the most filial, as for that Cheng biting gold, will the old man be afraid of him?" Let him come over! Hmph, don't look at it, my nephew is a protégé of the Son of Heaven, and my grandson is on duty in the province of Menxia. ”

Chen Zhengtai didn't expect the third uncle to be so rigid, but he still persuaded him, he knew that the third uncle was an iron rooster, but if he could take advantage of people, he would never give up, and the cow couldn't pull it back! I can't help but sigh in my heart, the third uncle is a talent, and he will have to reuse it in the future.

As for the third uncle, he still doesn't understand a little, now that the Chen family's employment cost is increasing day by day, why does he still swear that he wants to make a fortune?

It's really puzzling.

It can be seen that Chen Zhengtai's mysterious appearance has made the third uncle feel a lot more relieved!

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

Soon, the entrance examination for Erpigou University Hall will begin.

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

The Chen family had already distributed textbooks to the local people in the household, so that they could study on their own, and once they could pass the exam, they would be able to get three catties of fine food per month, in addition to that...... There is also a place to join the junior class of the University Hall.

In addition to these self-taught commoners, they were the first batch of wealthy families and merchants who purchased land and settled here.

There are not many people who have settled down, only a few dozen households.

In fact, the vast majority of these people have a choice, and they may not necessarily have to hang in the Erpigou University Hall.

Li Yifu and Hao Chujunren were also invited back to the school, although they were admitted to the Jinshi, but the imperial court has not yet been officially awarded, anyway, they are idle and idle, and they always have to be used.

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

So they were assigned to continue transcribing the textbooks.

At first, everyone copied it quite well, but the more they copied it, the more unbelievable it became.

Because the content of the latter has begun to detach itself from their understanding of things, all kinds of strange symbols, especially many mathematical formulas, make them feel very novel and incomprehensible.

But they're different.

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

The most important thing is that this textbook is copied one by one, first easy and then difficult, in the process of transcription, there is already some foundation, the more you copy it, although it feels a little jerky and difficult to understand, but slowly ...... I realized that something was wrong.

Li Yifu copied a mathematical formula, and then looked for a blank piece of paper with a suspicious look, bowed his head and calculated something, and calculated it for a long time... Eventually, in the midst of the dense drafts, he exclaimed, "This formula is really divine." ”

Hao Chujun and the others on the side were attracted by this exclamation, and they also looked at it curiously: "Brother Li Xian, this is ......"

Li Yifu's face was slightly excited, and his eyebrows fluttered and said: "It's really too godly, this formula, just apply it, but a few moments of effort, you can calculate a lot of calculations, senior brothers, you see ......"

As he spoke, his eyes were filled with excitement because of this momentous discovery.

The people of Datang are not exclusive to mathematics, after all...... Even the imperial examination has a special arithmetic exam, among the six arts of the gentleman, including 'etiquette, music, archery, royal, calligraphy, and mathematics', this last 'number', although it was interpreted by later generations of physicists as the study of rational numbers or qi numbers, it seems very compelling!

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

In this day and age, no one would deny that mathematics is helpful to people, after all...... In this era, the emphasis is on the Qi family governing the country and leveling the world, whether it is the Qi family governing the country, it is closely related to arithmetic, you are not even proficient in arithmetic, don't you become a loser? You don't understand the truth of living within your means, what kind of family do you have, governing the country?

The linguistic literature was unremarkable to Li Yifu, but the interesting thing about the study of this language was that it used a lot of spoken language to teach, rather than what the scholars admired.

Mathematics, on the other hand, is so powerful that it even makes Li Yifu feel the urge to kneel.

"The teacher is really talented, how did he come up with these?" Li Yifu sighed again.

The other eight people were thoughtful, you ask me, how do we know, can we break the teacher's head and see?

Wait until...... When they started copying physics and chemistry, it became more and more difficult.

At this time...... The Nine are no longer copying books, but more often than not, they are transcribing and thinking at the same time.

In fact, if something like this is jerky and difficult to understand, if it is obtained somewhere else, they will definitely disdain it.

Can it be ...... According to their understanding of the teacher, the teacher is an unfathomable person, and since the teacher is unfathomable, then everything must have a deep meaning, and since there is a deep meaning, then it is worth thinking about and studying.

It's not more serious, it's not tight, but when it's true, I feel a chill down my spine.

So much so that later, they didn't have much of the heart to transcribe, and when they copied a sentence, they had to stop and think about it.

Sometimes Chen Zhengtai will come and see them all 'grinding foreign workers', and he can't help but be angry!

Come, give you food and drink, and you will be fooled into something, and you will be punished for copying, and you will copy it three more times.

The nine people were locked up in Minglun Hall like this, except for eating and drinking, they were copying and thinking about forgetting to sleep and eat.

Many studies seem to be difficult to understand in the eyes of the Tang Dynasty, but Li Yifu and Hao Chujunren have discovered many mysteries.

"Look at this mathematics, and this physics, oh, and this chemistry, haven't you guys understood it? The great thing about this book is that it is easy first and then difficult, step by step, for example, this mathematics, if you have thoroughly referred to the first lesson, then the second lesson can be roughly understood, if you have thoroughly consulted the second lesson, this third lesson, you will have eyebrows, this book of teachers, it looks complicated, but as long as you follow this law, a little bit to eat thoroughly, the knowledge behind it can be a matter of course, here...... I don't know how much thought it took to put it. ”

The more Li Yifu talked, the more energetic he became, and the more he talked, 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 many textbooks have not been thoroughly understood, but now he is slowly beginning to grasp the rules!

He was originally an extremely intelligent man, and he was very good at drawing inferences: "It's just ...... What's the use of learning this? I know math, and I've made great progress in arithmetic lately, and I guess the same is true for all of you. The only thing that I can't see through is physics and chemistry, what is the use of physics, and what is the use of chemistry? ”

Hao Chujun is an extremely arrogant person, but now ...... He actually said: "The teacher does this, there must be the truth of the teacher, I now have mastered the law, but everything that is the teacher's things, is the treasure, he seems to just teach us to copy the book, on the surface it seems to want to save some labor costs for copying, but I faintly feel that he wants to take this opportunity to sharpen me and so on, his mind is really unpredictable, but if we do what he says, we will not teach us to suffer, have you forgotten, think about the beginning, we can't understand why the teacher called us to the school! But it wasn't until we were in high school that we didn't know ...... Teacher, this is an unknown method to improve our learning, so that we can go to high school. ”

Everyone nodded their heads, and couldn't help but show a little admiration, and their already tired body and mind were also greatly encouraged at once, and they seemed to feel ...... The teacher is becoming more and more unfathomable, and it has reached the point of shock!

Gao Zhizhou coughed: "Instead of us speculating on the teacher's mind here, it is better to copy it well, these ten days, I have copied every day, and I have been familiar with physics, but now although I can recite it backwards, many of these things can not be understood, but this does not matter, I believe that as long as I slowly understand it, I will be able to understand the mystery." ”

"We can have today, all thanks to the teacher, now, the teacher has given us a great opportunity, if we don't seize it well, we will be unbearable."

"Yes."
