After Shen Rui was surprised, he quickly calmed down and immersed himself in making rice.
Zhang Yue on the side had a hint of envy in her eyes, but she didn't say much, as she seemed to be used to it.
She took a bite of steamed buns and asked Shen Rui curiously: "Why didn't you buy food from the canteen?"
Shen Rui had just finished eating two potatoes and raised his head and said, "Classmate Zhang Yue, you seem to have misunderstood me. In fact, my family is just an ordinary peasant family. We don't have a back door, and we don't have any good conditions."
Of course he understood what the other party meant. He knew from the memory of his predecessor that there was a difference between a large canteen and a small canteen.
The large canteen has a fixed supply, while the small canteen can be purchased using a circulation coupon.
If your family is wealthy, you will naturally have many such circulation coupons, which can be used to purchase many additional supplies.
For Fu Yunqing's food to be so good, he must have bought it from the canteen.
However, it was impossible for Shen Rui to buy it himself. His family had very little savings and had to keep it for big use.
If he were in the past, he might not be able to tell the true situation of his family so calmly, but after several years of social life, he understands very well that you should not be hypocritical and cover up your family environment. It will not bring you any glory. All you need to do is Be down-to-earth and work hard to change your family environment.
Zhang Yue was slightly moved. High school students at this age are still very vain. Many people are unwilling to say that their family conditions are poor, but this classmate is blunt.
"Sorry, I misunderstood you. It seems that your physical skills must be very good." Zhang Yue said sincerely.
Shen Rui nodded and said he didn't care. This classmate was outspoken and would not plot behind others' backs.
Fu Yunqing's eyes lit up slightly, but he didn't say anything.
The three of them finished their meal quickly and then went to study in the evening.
At this time, it was completely dark in the school. There were no street lights on the road. Only the lights from the classrooms in the distance barely illuminated the road.
In the playground opposite, there are still a few street lights lit, and many people are training there.
Fu Yunqing asked: "Are you going to read a book or go to the playground to exercise?"
"I'll go back and read." Shen Rui decided directly.
"I, I'd better go to the playground to practice more and try to get started early. In this way, I can work with the school's field team on weekends." Zhang Yue thought for a while and said.
This is the second time Shen Rui has heard this concept. He has very little memory about this concept. He only knows that the school organizes gifted students and senior students to go to some of the more popular places around the castle on weekends under the leadership of experienced teachers. In a safe area, you can do gathering and hunting, or go to some villages and camps to collect supplies.
It is not only to increase experience, but also to make full use of manpower.
It seems that Zhang Yue's family is better than his, at least he has more experience.
Fu Yunqing nodded and said to Shen Rui: "Well, student Shen, I will go to training with Zhang Yue. You can study by yourself."
Shen Rui nodded and left.
When I returned to the brightly lit classroom, I saw that there were not many people in the classroom.
He glanced at it, returned to his seat, and immersed himself in reading, while continuing to sort out the memories of this world.
Before dinner, he had already browsed through the books on the desk.
He took out a book and started to read it.
The title of the book only has two words: "Geography".
In high school in his previous life, he remembered clearly that the college entrance examination of his year did not take geography, history, and biology, but only five subjects, mathematics, English, Chinese, physics, and chemistry.
However, in this world, "Geography" and "Biology" have become the key points. Physics, chemistry, and mathematics are also included, but the content has changed. But in English and Chinese, he did not see where the books are...
By the way, there is an ideological education class on Friday afternoon.
Shen Rui looked through the "Geography" book carefully, and some questions were slowly solved.
The course "Geography" naturally includes astronomy, and the same goes for geography in previous lives.
This book tells the story of fifteen years ago, when the sun changed, the apocalypse came, and strange things were rampant.
It took humanity five full years to gradually recover, using the remaining industrial system to build castles everywhere to defend against aberrations.
There is a map of China in the book. There are scattered dots on it, all of which are fortresses. This is the age of castles.
From south to north, there are hundreds of large and small fortresses in the entire Chinese homeland, more in the south and fewer in the north.
The standard fortress is a city wall with a height of 50 meters, made of cement and reinforced concrete, and a thickness of 10 meters. It can defend against the impact of monsters below the fifth level.
The large fortress wall is 150 meters high and 30 meters thick.
The walls of the small fortress are 20 meters high and 5 meters thick.
Human beings now live in the form of fortresses. Human life is despicable, but human power is precious, and every minute cannot be wasted.
This seems to be a contradiction, but in fact it is not. The valuable manpower refers to those who can gain a foothold in the wild, that is to say, those who have at least first-level physical skills.
Those who cannot gain a foothold in the wild can only rely on castles for protection. Obviously, the human value is very low. The resource output in the castle must be limited, and the jobs are also limited.
Only the vast wilderness can support large-scale primary industries such as collection and planting. Relatively speaking, industries occupy less space and can operate within the castle.
Of course, it is not that no one has thought about building multi-story greenhouse agricultural buildings in the castle and using electric energy instead of solar energy. However, the investment is too high. Secondly, any life has the risk of mutation. The higher the density, the higher the risk of mutation.
Even plants cannot escape this law.
If you engage in multi-story greenhouse agriculture in a densely populated castle, once mutated plants appear, the harm can be imagined.
You must know that many plants can bloom and contain pollen. Once such plants mutate, they will spread quickly and annihilate the entire castle like a plague.
The book gives several examples of southern castles.
There are abundant water resources and convenient hydroelectric power generation there. Some people have thought about using solar lights to build multi-story greenhouse buildings. However, several major plant disasters have occurred because of this.
It suddenly broke out within the castle, spread rapidly, and finally became difficult to defend, and the prosperous fortress turned into ruins.
The most famous one is the "Xiabao Ruins", located near Nanjiang River, where a huge vine monster that mutated from a cucumber still stands.
High city walls, coupled with some special protective measures, can block similar plant disasters.
It is precisely because of this that the primary industry is struggling and food supply is difficult. Relatively speaking, the secondary and tertiary industries have been able to survive a lot.
Necessary mining areas such as coal fields, oil fields, and iron ores have special castles built for protection.
A coalfield only covers an area of tens of square kilometers and can supply hundreds of millions of tons of coal every year, which is basically enough in this apocalyptic world. However, growing food on dozens of square kilometers of land cannot feed many people.
