When Zhang Hong left, how old was his son? How could he think about transferring Zhang Hong back now? If no one caused trouble here, Li would not believe it. After pondering for a moment, Li said with a smile: "Son, who told you to transfer Zhang Hong back?"

"No one told the child!" Zhu Yijun pouted and acted cute, but his heart skipped a beat.

He shot himself in the foot. Obviously, his mother suspected that he was being used. Zhu Yijun could not blame others at this time! The key is that he couldn't even throw it away. In the flash, Zhu Yijun decided to force the blame.

"That's when the son-in-law heard a group of eunuchs chatting that day. They said that there was a very good eunuch in the palace before. He often advised his father and was a virtuous minister." Zhu Yijun said with a straight face and looked serious: "Master Zhang taught his son-in-law to be close to virtuous ministers and stayed away from villains."

"I just think that if he is a wise minister, then let him come to Erchen's side!"

After hearing his son's words, Li was even more sure that someone was muttering around his son, but Li also knew that there was no way to continue investigating this, so he couldn't let his son recognize him!

After thinking about it, Li still felt that Zhang Hong should be transferred back. First, Zhang Hong is indeed a good eunuch, and second, it cannot undermine his son's enthusiasm. He is close to wise ministers and stays away from villains. How good it is to say!

"Okay!" Li said with a smile: "Then let the Sili Superintendent draw an imperial edict!"

After hearing what his mother said, Zhu Yijun immediately smiled happily, looking extremely cute.

Turning around, Li glanced at Feng Bao behind Zhu Yijun, and said with a dark face: "Ben Feng, don't let someone gossip in front of the emperor in the future. Can the people in the palace even control their own mouths?"

"Don't worry, I'll make arrangements when I go back!" Feng Bao hurriedly bowed, but hated Zhang Jing in his heart.

In this palace, if you want Zhang Hong to come back the most, it is undoubtedly Zhang Jing. You must know that Zhang Jing had just entered the palace to be an eunuch, and that was worshipped by Zhang Hong, who was Zhang Hong's godfather.

Compared to Zhang Jing and Zhang Cheng, Zhang Hong has a better reputation and is of high qualifications. If he really goes against him, he will be in trouble.

With Zhang Jing and Zhang Cheng, you can imagine what happened. Feng Bao secretly hated him, but he didn't dare to show it on his face. When Feng Bao was just fighting Gao Gong, he was officially proud, but he didn't expect to be kicked by Zhang Jing and dodged to his waist.

"You guys wait for me!" Feng Bao was so cruel that he would never let them succeed.

Zhu Yijun naturally didn't know that Feng Bao hated Zhang Jing, but Zhu Yijun knew that Zhang Hong was transferred back, and the most unhappy one would definitely go to Zhang Jing. However, Zhu Yijun was too lazy to care about Feng Bao, and he had more important things to do.

This more important thing is to write textbooks, a mathematics textbook.

After the school starts, Zhu Yijun will have a group of people studying with him. Although it is mainly based on the Four Books and Five Classics, if he really learns the Four Books and Five Classics, what else can Zhu Yijun do in the school?

Mathematics is the basis of all learnings. If you want to learn other things, you naturally have to start with mathematics.

It is urgent to write a mathematics textbook. Starting from primary school textbooks, addition, subtraction, multiplication and division, this is the first volume prepared by Zhu Yijun. After three years, he began to explore physics and chemistry.

If you learn for three years, you will have no choice but to learn after three years. Anyway, Confucianism also emphasizes the six arts of a gentleman, and mathematics is also one of the six arts of a gentleman.

The location of the academy was soon decided, and the address was in Xiyuan, which used to be the place where Emperor Jiajing lived, or the place where alchemy was refined. Speaking of alchemy, Zhu Yijun had an idea, perhaps he could train these guys to become chemists?

It is also OK to do chemistry. Write it down first and try it later.

Xiyuan is actually the Zhongnanhai in later generations. At this time, it was called Beihai, Zhonghai, Nanhai, and Nanhai, collectively known as Taiyechi, and it is a royal garden. Zhu Yijun felt that it was very suitable to place the Academy here. It is big enough and comfortable enough.

Since the death of Emperor Jiajing, the Xiyuan has been idle and is very suitable to use it.

Although this place has not been built like that of later generations, it is a royal garden after all. His grandfather, Emperor Jiajing, has lived here for so long, so there is no problem with decoration. Zhu Yijun ran to Li's place and said that the school was placed here, and Li agreed very simply.

Li has always been very supportive of his son's study.

In the room of the Ganqing Palace, Zhu Yijun was tinting pencils at this time, or directing the eunuch to tinker with pencils.

"Chen Ju, do you know how to grind it into powder?" Zhu Yijun looked at the little eunuch Chen Ju and said directly: "Grind it finer, and then put clay." Sitting on the chair, drinking tea, and speaking from time to time.

Chen Ju didn't dare to neglect at all. There were no trivial matters that the emperor personally told!

"After you're done, apply glue on the paper, then roll it up, and be sure to roll it tightly."

This kind of pencil was seen by Zhu Yijun in later generations. In fact, it was a newspaper as a pen holder, not a wooden pen holder. It was considered a kind of resource reuse, and Zhu Yijun moved it directly to the Ming Dynasty.

Save time, effort, and money. Otherwise, you should throw away the waste paper. It is just right to use it to make a pencil.

The little eunuchs were very busy, but this thing itself was not difficult and was made soon, but it was not useful and needed to be dried. Looking at the first batch of pencils brought out, Zhu Yijun nodded with satisfaction.

Mathematics is very paper-intensive, and the guys in the school don’t pay tuition fees, so it’s okay to let them use a brush.

The pencil is so good that it can be wiped off after use, saving money and effort. When the pencil is done, you can write the textbook by yourself. Zhu Yijun can't play with the strokes and lines, and so on. Besides, if you really use the brush, how thick the book would have to be written.

The key is that I am tired. If I really write a book like that, I will probably be done.

After three days, the pencil was dry. Zhu Yijun took the pencil sharpened by the eunuch and drew it on the paper. He nodded with satisfaction. The quality was really good. He took a drawing board and spread a piece of paper. Zhu Yijun started painting at Feng Bao.

"Feng Daban, sit down, don't move, I will draw a portrait for you."

Although Feng Bao didn't know what the portrait was, the emperor was happy as long as he sat there without moving.

Zhu Yijun's sketch is pretty good. I learned it from my girlfriend for a while in my previous life. Soon, a portrait appeared on the paper, and the eunuchs and palace maids standing behind Zhu Yijun all showed shocked expressions.

After finishing the painting, Zhu Yijun nodded with satisfaction. It was not bad, his hands were a little raw, but it was quite beautiful.
Chapter completed!
