(Recommended reading: Cai Yong completely forgot the time, forgot about the surroundings, and was completely immersed in studying arithmetic.

This made the people around cry and laugh, but everyone didn't dare to disturb Cai Yong, so they waited quietly.

Class is out again, but Cai Yong is still immersed in it, and Ye Chen asked those teachers to do what they should do.

"This is a great book. The content inside is incredible. Cai Yong rubbed his eyes and said excitedly.

"Daddy, you've been reading it for more than an hour, what kind of book is this?" Cai Yan is very smart, she asks about the content of the book, in fact, she already knows what the book is, but she just reminds Cai Yong and lets him know how long he has been reading, because Cai Yan knows that Cai Yong often forgets time after being fascinated.

Forget the time at home, forget it, forget it, here Ye Chen and Zhang Jing next to him have been waiting for him quietly for a long time.

Sure enough, Cai Yong smiled awkwardly when he heard this, then became serious again, and said to Ye Chen: "Youguo, who compiled this book, please introduce it, and after obtaining his consent, I want to bring the book back to Luoyang and let the court promote it." ”

Cai Yong's words made Ye Chen almost squirt out, firstly, he didn't expect Cai Yong to think that everyone made the compilation, and secondly, he thought that this Cai Yong was too naïve, what kind of imperial court is the imperial court now, and let the imperial court promote it?

"Don't hide it from Master Cai, these textbooks were compiled by many teachers and scholars, not by one person."

Cai Yong took a breath, he suddenly felt that this Ye Chen could do anything, but he didn't want to pursue this, he just wanted to get this book.

In fact, this book was indeed compiled by Ye Chen organized many teaching exercises, Ye Chen listed all the mathematical knowledge he knew, and then handed it over to those teachers to study slowly, and then compiled it into a textbook.

Although Ye Chen knows a lot of mathematics, he has not formed a system, he can only write what he remembers, and the knowledge of primary, junior high and high school is interspersed with it, and it is difficult to use it for teaching if it is not reorganized.

He gave what he would know to the instructors, let them conduct research, and then compile it according to the degree of difficulty, Ye Chen also asked them to continue research, and if there were any new discoveries, they would add them.

"Okay, since Youguo can call the shots, then I want to take this book back and hand it over to the imperial court." Cai Yong said to Ye Chen very seriously.

"Lord Cai is polite, this is no problem at all, this is just a beginner, we still have a few advanced textbooks, Lord Cai can also take them back."

Ye Chen's words made Cai Yong dumbfounded. What the? This is just the beginner one, how many more advanced ones are there?

Do you want to hit people like this, this elementary one has already immersed Cai Yong, so what will be the advanced one?

Cai Yong felt that his head was not enough, this was just a school that had not been established for a few years, and there were no big names in charge, so he could compile such advanced teaching materials.

In fact, most of this is Ye Chen's credit, he knows the role of mathematics, his business has become bigger, a lot of data needs to be counted, a lot of things need to be calculated, according to the original level of mathematics, many things can also be done, but it is very troublesome.

That's why Ye Chen spent a lot of energy compiling these books, such as Mandarin and classics, Ye Chen just provided a general direction, and didn't care about anything else.

Speaking of miscellaneous studies, in fact, this miscellaneous study is not a hundred schools of pre-Qin princes, but a course compiled by Ye Chen.

The content of the course covers physics, chemistry, biology, astronomy, geography and so on, so why doesn't Ye Chen separate these disciplines?

In fact, it is very simple, that is, Ye Chen doesn't know so much, and he can't compile an independent discipline alone, so he can only list all the knowledge he knows, then mix it together, and then slowly supplement it in practice.

Cai Yong originally thought that miscellaneous studies were the rest of the hundred schools of Zhuzi, but after reading it, he didn't understand a lot of things, but he knew that it was different from miscellaneous studies in the pre-Qin period, and Cai Yong was going to lash out, but when he thought that he was going to take away the books on arithmetic and promote them, he didn't blame Ye Chen.

"Youguo, this school teaches classics, which is very good, but the old man thinks that this miscellaneous study is really a waste of students' time, and it should be avoided." Although Cai Yong did not accuse Ye Chen, he did not say nothing.

Ye Chen scolded secretly in his heart, in his opinion, this classic must be learned, but it cannot be improved to a more important degree than others, but he does not dare to refute Cai Yong, and there is no point in arguing with him.

What Master Cai said is that although miscellaneous studies are not as good as the six arts, they can also provide new thinking, new directions, rich knowledge, and consider problems from many aspects and angles, and there are more ways to solve problems at the same time. Therefore, while the school teaches the six arts, miscellaneous studies can also be taught a little bit. ”

Ye Chen said very tactfully, Cai Yong didn't say anything after listening to it, Cai Yong didn't agree with Ye Chen's statement in his heart, but this is just a county school, the scope of influence is not large, and Cai Yong is too lazy to care.

Cai Yong skipped this question, didn't entangle with Ye Chen, and then picked up the arithmetic book and said, "There are more advanced books than these arithmetic books, can you also lend them to the old man." ”

Ye Chen saw that Cai Yong had misunderstood, thinking that he had hidden the high-level books, but in fact he was not.

"Master Cai, we have built a higher school in the county seat of Yuxian County, and after studying in these schools, you can enter the advanced school to continue your studies, where more advanced knowledge is taught, so where are the advanced arithmetic textbooks."

The mathematics in the senior school, part of it is junior high school knowledge, and part of it is high school knowledge, and the same system is not complete, but that is where Ye Chen cultivates senior talents, and the teaching is naturally deeper.

Many of the basic talents of the Ye family came out of the senior school, and the senior school was established not long ago, because there were no students at the beginning, and it was not established until the following school was run for two or three years, and some students who studied well were sent to study inside, and after two or three years of study, they were enriched to various places.

This time, the officialdom of Liaodong changed blood, and many talents came out of it, these people have mastered some modern knowledge, their administrative efficiency is much higher, and they are absolutely loyal to the Ye family.

The senior school is actually equivalent to a university, but now it is just a start-up, many teaching and learning are not of a high level, and the books are not systematic, but it doesn't matter, only after having a large number of talents can the whole system be completed slowly.

Cai Yong listened to Ye Chen's words and knew that he had misunderstood Ye Chen, so he didn't continue to entangle, and offered to go to the academy to see how the students were learning.

This academy is very important to Ye Chen, in the future, Ye Chen will put a lot of energy into this, and he also needs to investigate in detail, so he took Cai Yong to take a look.
