When Cheng Jinzhou arrived home, it was already dark. Cheng's mother was still waiting in the room. When she heard the sound outside, she ran out with her skirt, half complaining and half distressed, "Don't go out so late in the future. You are weak and you need to rest more on weekdays. It is the rule of the ancestors to go to the private school in the clan. There is no way to do it. Don't run around after school."

"I'm fine." Looking at Cheng's mother's worried look, Cheng Jinzhou felt warm. When he recalled that when he was at home, he would go back late every time and get the same words. He couldn't help laughing out loud, and then he felt a little sad.

Whether it is traveling through time or otherwise, you always have to get some and lose some.

"I'm still laughing." Cheng's mother Qiao said angrily: "It will be the day to worship ancestors in a few days. What should you do if you are blown by the cool breeze again?"

Suddenly, Cheng Jinzhou felt like time and space were intertwined, and he couldn't help but rub his eyes and said, "I went to the other courtyard today to relax."

Cheng's mother looked at her son up and down, took her vest and put it on him, and said, "I heard that you bought a lot of rice and flour and went to the yamen to file a record?"

The prefect is Cheng Jinzhou’s cheap father. If you have any matters about Cheng Jinzhou, you will be informed by the minor officials.

Cheng Jinzhou laughed and explained casually: "I want to make something."

Since the existence of astrology warlocks, food has become more and more important. It is not only a strategic reserve, but also an object of research by countless astrology warlocks. In private schools, teachers are also indispensable to using various food for experiments.

Cheng's mother didn't really care where the food was consumed. She said little by little Cheng Jinzhou's head: "You know how much grain you only get per acre of land. You can make something casually, but how many years do people spend."

This is what I just learned today. Cheng Jinzhou smiled and said, "Two kinds of slopes a year, you can get 3 stones of grain, and 6 stones of grain on flats. If there are two types of paddy fields, you can get 10 stones. The best land can have six times the slopes, which is about 18 stones of grain, right?"

18 stones of grain are about 900 kilograms, which is basically the best land and the most meticulous work can only be achieved. However, there is still a huge gap with modern agriculture. In the 21st century, a ton of grain fields with a mixed yield of 1,000 kilograms per mu is no longer an exception. If it weren't for this, 1.8 billion mu of land would not be able to support 1.3 billion people.

Cheng's mother looked at Cheng Jinzhou in surprise, reached out and pulled his face, and said, "It's not bad, it seems that she has read some books."

The big girl next to her immediately said likablely: "The third brother is so smart and works hard in school, so he must have a great prospect."

As she said this, Cheng's mother sighed and patted Cheng Jinzhou's head and said, "I don't ask you to be so promising, just be safe and sound, like your uncle, what a powerful person..."

As he said that, he started to sob.

Cheng's elder brother was originally the most promising astrology warlock in the Zheng family in Hexi, but unfortunately he was killed in the airship while leading the troops to fight.

Cheng Jinzhou didn't know how to comfort him, but fortunately, Cheng's mother quickly wiped away her tears. Zhan Yan said, "Don't talk about these unhappy things, go back and clean up and go to bed. Zhuer, go over and help me."

He was driven into the east wing room helplessly. Cheng Jinzhou had to wash up again under the servitude of two maids, muttering unwillingly: "It's only 9 o'clock, I've slept at noon."

Zhu'er was about fifteen or sixteen years old. While gently wiping Cheng Jinzhou's face with a towel, she smiled and said, "If I hadn't been waiting for you today, the young grandma would go to bed at around seven o'clock. The third brother studied so late every day, so it would be nice to have a nap."

Influenced by the West, the Daxia Dynasty also began to use the 24-hour system, especially wealthy families.

After taking off his shoes and being washed again, Cheng Jinzhou simply lay on the bed, putting a pillow on his back and said, "Zhu'er, light two candles for me, and I'll sit and read a book."

Zhuer took out four-pillars of candles as thick as thumbs from the drawer and lit them near the head of the bed. Just like China in the past, the candles were bright and the price was also very high. However, ordinary people dared not even use oil lamps.

The two girls walked out one after another. Cheng Jinzhou Shiran took out the copied manuscript from his arms. There were about two hundred words per page, and the small fly heads were written in densely.

A normal candle usually produces about 12 lumens of luminous flux, and 4 branches together, which is quite good as a reading lamp.

Cheng Jinzhou raised his foot and read "Geometric Origin" again from beginning to end. It really seems that he has never read this book for so many years in school. A normal mathematics student rarely read "Geometric Origin" as a selection after 2,000 years.

And in this world, making good use of every book may be his all advantage.

Most of the candles were used, but Cheng Jinzhou just packed the copy and buried his head in the middle and fell asleep.

The next day, I went to class as usual, changed into a new classroom, and the teachers and classmates also changed into people. In terms of educational environment, it is very similar to the 21st century university.

In Jinchuan Prefecture, Cheng's private schools are quite famous because every five years, there are more than a dozen imperial examinations. When you are lucky, you can also produce star sorcerers with star ranks. Unlike those who cheat by their body shape, you are lucky enough to become a star rank with grades, just like a carp jumping over the dragon gate and jumping into the top level of the empire.

In the entire Daxia Dynasty, no one must pass the grade assessment every year. Of course, countless astrology warlocks of ordinary levels can be born, although for most people, becoming astrology warlock is already extremely difficult.

The education Cheng Jinzhou received was mainly based on the imperial examinations. Even if the conditions were met for wealthy families, if you did not have the talent of a star sorcerer, you would rather be a civil servant than be a little smarter and always get a good position. In the field of astrology, the advantages brought by your family background would be much weaker.

The young professor on the stage still shook his head and read a sentence by himself, asking the students below to read a sentence. The voice was clear and fluent, but he did not have the courage of Mr. Cheng yesterday, and pretended not to see any behavior of Cheng Jinzhou.

Cheng Jinzhou was so happy that he turned out a few pages of the geometric originals he copied, and calculated them with a quill pen, trying to memorize all the proof process in his heart. Occasionally, he would look out the window and think in a daze.

In this way, his behavior is naturally incompatible with others, and his nagging actions will inevitably affect other students.

Soon, a "swish" sound came from beside him, and a child voice came: "The reputation of my nobles and honors in the dynasty was corrupted by people like you."

The resentment in the words is very deep...

Cheng Jinzhou couldn't help but turn his head. It turned out to be a little boy wearing a light green horse clip. Maybe he was only 10 years old. He had never seen the memories of the sick-sick Cheng before.

When Xiao Zhengtai saw Cheng Jinzhou looking directly at him, he immediately said in his voice that had not changed yet: "If you don't learn and do not know how to show off, why do you show your example?"

This guy was talking one by one. Cheng Jinzhou couldn't help laughing and said, "My reputation of aristocrats in the dynasty has long been over. What does it have to do with me?"

The contradictory and sharp social relationships had nothing to do with self-discipline, so Cheng Jinzhou would never discuss it with a little kid in detail.

The little boy still had a child voice and said loudly: "The noble family is the foundation of my dynasty..."

"Have you learned from your father?" Cheng Jinzhou interrupted the other party impolitely, shook his hand, and said with a lesson: "Study hard and don't stare at me. If you have time to look at me, it's better to put a little bit of energy in the textbook, and it's not in vain that your father will send you to a private school."

Cheng Jinzhou also had a long hatred for studying, so he couldn't help but say a few more words to the little boy. Seeing that all the classmates in the room looked over, he simply stood up and bowed and said, "Sir, I'm anxious."

Forget it, I just left with a long and sad face, and I was so angry that I was yelling from afar: "I'm staring at you..."

The professor was unwilling to stop Cheng Jinzhou and sighed secretly. The Cheng family's private school has a wide range of students. Not only did Shaonan City and some families in nearby Zhoucheng send their children, but even those newly emerging big families will also send their concubines to study. This job is not like the superficial scenery.

The world of elementary school students is still uneasy...
