Chapter 7 The World of Primary School Students
When Cheng Jinzhou arrived home, it was already dark, and Cheng's mother was still waiting in the room. When she heard the noise outside, she ran out with her skirt in her hands, half complaining and half feeling distressed: "Don't go out so late in the future, you are so weak. Weak, you need to rest more on weekdays, and going to the private school in the clan is an ancestor's rule, if there is nothing you can do about it, don't run around after school."

"I'm fine." Looking at Cheng's mother's worried face, Cheng Jinzhou's heart was also warm. He recalled that when he was at home, every time he went back late, he got the same words, and couldn't help laughing out loud. Turned a little dejected.

Whether it is time-traveling or otherwise, there is always something to be gained and something to be lost.

"Still laughing." Cheng's mother Qiao said angrily: "In a few days it will be the day to worship the ancestors. What if you are blown by the cold wind again?"

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

Cheng's mother looked at her son up and down, then took a waistcoat and put it on him. Fang said, "I heard that you bought a lot of rice noodles and went to the Yamen to register?"

The magistrate is Cheng Jinzhou's cheap father, and there are small officials who will come to inform you about Cheng Jinzhou's affairs.

Cheng Jinzhou smiled and explained casually, "I want to make something."

Since the beginning of the Star Warlocks, food has become more and more important. It is not only used as a strategic reserve, but also the subject of research by countless Star Warlocks. In private schools, teachers inevitably use various grains to conduct experiments.

Cheng's mother didn't really care where the food was used. She tapped Cheng Jinzhou's forehead and said, "You know how much food is harvested per acre of land. You can make whatever you want, but it takes a year for many people."

I just learned this today. Cheng Jinzhou said with a smile: "There are two types of sloping land a year, and 3 stones of grain can be harvested, and 6 stones can be harvested on flat land. If there are two types of paddy fields, 10 stones can be harvested. The best land has slopes. Six times that, almost 18 shi grains, isn't it?"

The grain of 18 shi is almost 900 catties, which is basically the best land and the most meticulous work can be done.However, there is still a huge gap with modern agriculture. In the 21st century, grain fields with a mixed yield of 1000 kilograms per mu are no longer a special case. If this were not the case, 18 billion mu of land would not be able to feed 13 billion people.

Cheng's mother looked at Cheng Jinzhou in surprise, stretched out her hand and pulled his face, and said, "Not bad, it seems that he has read some books."

The big girl next to him immediately said pleasantly: "Third brother is so smart and works hard in school, so he must have great promise."

She said so, but Cheng's mother sighed, patted Cheng Jinzhou's head and said: "I don't ask you to be more successful, just be safe and sound, like your uncle, what a powerful person..."

As he spoke, he started to weep.

Cheng's mother's eldest brother was originally the most promising star warlock of the Zheng family in Hexi, but unfortunately he was killed on the airship when he was leading the army in battle.

Cheng Jinzhou didn't know how to comfort him, but fortunately, Cheng's mother quickly wiped away her tears and said with a smile, "Stop talking about these unhappy things, go back and pack up and go to sleep, Zhu Er, go and do me a favor."

Reluctantly being driven into the East Wing, Cheng Jinzhou had no choice but to wash up again under the service of two maids, muttering unwillingly: "It's only 9 o'clock, I slept in at noon."

Zhu'er, who was about fifteen or sixteen years old, gently wiped Cheng Jinzhou's face with a towel and said with a smile: "If I hadn't been waiting for you today, my young lady would have gone to bed at around seven o'clock. Third brother learns so much every day." It's good to take a nap at night."

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

After taking off his shoes and washing his feet, Cheng Jinzhou simply lay on the bed, put a pillow on his back and said, "Zhu'er, light two candles for me, and I will sit and read a book."

Pearl took out a four-pillar thumb-thick candle from the drawer, lit it and put it near the head of the bed.Just like China in the past, the brightness of candles is very high, and the price is also high. Ordinary people dare not even use oil lamps.

The two maids went out one after another, and Cheng Jinzhou Shi Shiran took out the copied manuscript from his bosom. There were about two hundred characters per page, densely written in small script.

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

Cheng Jinzhou raised one foot and read "Elements of Geometry" again from the beginning to the end. To be honest, he has never read this book after so many years in school - a normal mathematics student, after 2000 years , and rarely take "Elements of Geometry" as an optional reading.

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

After using up most of the candle, Cheng Jinzhou just put the manuscript away and fell asleep.

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

Within Jinchuan Prefecture, the Cheng family private school is quite famous, because every five years, it can produce more than a dozen imperial examination scholars. If you are lucky, it can also produce star-level star warlocks, which are comparable to those Unlike those who cheated by their body size, those who were lucky enough to become a Star Soldier with a rank were like a carp jumping through the dragon gate, leaping to the top of the empire.

In the entire Great Xia Dynasty, one person might not be able to pass the rank evaluation every year. Of course, countless ordinary-level star warlocks could still be born, although for most people, becoming a star warlock is extremely difficult.

The education Cheng Jinzhou received was mainly based on the imperial examination. For a wealthy and famous family, even if the conditions can be met, if you don't have the talent of a star warlock, it is better to become a civil servant - if you are a little smarter, you can always find a good position.In the field of astrology, the advantages brought by family background are much weakened.

The young professor on the stage was still shaking his head, reading a sentence by himself, and asked the students below to read a sentence.The voice was very clear and fluent, but he didn't have the guts of old Mr. Cheng yesterday, and he pretended not to see any of Cheng Jinzhou's actions.

Cheng Jinzhou was so happy that he turned out a few pages of the Elements of Geometry that he had copied, and used a quill pen to calculate with difficulty, trying to memorize all the proof processes. Occasionally, he would look out the window, as if thinking sluggishly.

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

Soon, a "chi" sound came from the side, and a child's voice came: "The reputation of our noble family members was ruined by people like you."

The resentment in the words is very deep...

Cheng Jinzhou turned his head involuntarily, and it turned out to be a little boy wearing a light green vest, maybe only 10 years old, looking for the memory of the sick child Cheng, but he had never seen it before.

When the young lady saw Cheng Jinzhou looking directly at her, she immediately said in a childish voice that had not yet changed her voice: "If you don't learn and have no skills, how can you set an example for others?"

This guy talks in a set way.Cheng Jinzhou couldn't help laughing and said, "My reputation as an aristocrat has been ruined long ago, so what does it have to do with me?"

The sharply contradictory social relations have nothing to do with keeping oneself clean, so Cheng Jinzhou would not discuss it in detail with a little kid.

The little boy's childlike voice remained the same, and he amplified his voice: "The noble relatives of the family are the root of my dynasty..."

"Learned it from your father?" Cheng Jinzhou interrupted the other party rudely, shook his hand, and said harshly: "Study hard and don't stare at me. You have time to look at me, so why not take a break?" If you focus on your textbooks, your father will send you to a private school in vain."

Cheng Jinzhou also has a long-standing hatred for studying, so he inevitably said a few more words with the little boy. Seeing that all the classmates in the room looked over, he simply stood up and cupped his hands and said, "Sir, I am anxious."

Forget it, he just walked away like that, leaving behind a sad-faced, hot-hearted Angry Tai who roared from a distance: "Where am I staring at you..."

The professor also didn't want to stop Cheng Jinzhou, and sighed secretly. The Cheng family's private school has a wide range of students. Not only some families in Shaonan City and nearby prefectures will send their children here, but even those new big families will also send their children home. The bastard came to study, this job is not what it looks like on the surface.

The world of primary school students is still not peaceful...
