Future library

When Cheng Jinzhou got home, it was already dark. Cheng's mother was still waiting in the room. When she heard the noise outside, she ran out with her skirt in hand and said half complaining and half distressed: "Don't go out so late in the future. Your body is too weak." Weak, you should get more rest on weekdays. It is the ancestral rule to go to the clan's private school. If you can't help it, don't run around after school."

"I'm fine." Seeing the worried look on Cheng's mother's face, Cheng Jinzhou felt warm in his heart. He recalled that when he was at home, every time he went back late, he would get the same kind of words, and he couldn't help but laugh out loud. Then he became a little sad.

Whether it’s time travel or something else, you always have to gain something and lose something.

"Still laughing." Cheng Muqiao said angrily: "The day of ancestor worship will come in a few days. What will you do if you get hit 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 daddy, and there is a small official who will inform him about Cheng Jinzhou's affairs.

Cheng Jinzhou chuckled 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 of grain, right?"

18 shi of grain is almost 900 kilograms. It is basically the best land and the most meticulous work. However, there is still a huge gap with modern agriculture - in the 21st century, grain fields with a mixed yield of 1,000 kilograms per mu are no longer a special case. If not, 1.8 billion acres of land would not be able to feed 1.3 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 eldest girl next to him immediately said pleasantly: "Third brother is so smart and works hard in school. He must have great potential."

As she said this, Cheng's mother sighed, patted Cheng Jinzhou's head and said, "I don't ask you to be successful, just stay safe, like your uncle, what a great person he is..."

As he spoke, he started to cry.

Cheng's mother's eldest brother was originally the most promising star warlock of the Zheng family in Hexi. Unfortunately, he was killed in an airship when he was leading troops 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 bed. Pearl, please go over and help me."

Having no choice but to be driven into the east wing, Cheng Jinzhou had to wash up again under the service of two maids, muttering unwillingly: "It's only 9 o'clock, I slept 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 late, you might as well take a nap.”

Influenced by the West, the Xia Dynasty also began to use the 24-hour clock, especially among wealthy families.

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

Pearl took out four thumb-thick candles from the drawer, lit them and placed them near the bedside. Just like in China in the past, candles were very bright and expensive, but ordinary people didn't even dare to use oil lamps.

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

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

Cheng Jinzhou raised one foot and read "Elements of Geometry" from beginning to end again. To be honest, he had never read this book in so many years in school. A normal mathematics student would read "Elements of Geometry" after 2,000 years. , and rarely take "Elements of Geometry" as an optional reading.

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, there may not be one person who can pass the grade assessment every year. Of course, countless ordinary-level star warlocks can still be born, although for most people, becoming a star warlock is already 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 still shook his head, read a sentence to himself, and asked the students below to read a sentence too. His voice was clear and fluent, but he lacked the courage of the old man yesterday and pretended not to notice anything Cheng Jinzhou did.

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 couldn't help but turn his head, and it turned out to be a little boy wearing a light green vest, maybe only 10 years old. Looking at the memory of the sick man Cheng, he had never seen him 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 the same way. Cheng Jinzhou couldn't help but laugh and said: "The reputation of my noble family has been ruined long ago. 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 loudly said: "A noble relative of the aristocratic family is 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 had a long-standing hatred for studying, so he couldn't help but talk to the little boy a few more words. Seeing all the classmates in the room looking over, he simply stood up and cupped his hands and said, "Sir, I'm worried."

That's all, he just walked away, leaving behind a sad face and a burning angry heart, shouting from a distance: "I was staring at you..."

The professor did not want to stop Cheng Jinzhou and sighed secretly. The Cheng family's private school has a wide range of students. Not only some families from Shaonan City and nearby cities will send their children here, but also those newly rising big families will also send their children to their families. The concubine came to study, and this job was not as glamorous as it seemed.

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