The full-scale tuba is in the apocalypse

Chapter 11 Geography
After Shen Rui was surprised, he quickly calmed down and buried himself in cooking.

Zhang Yue at the side showed a hint of envy in her eyes, but she didn't say much, as if she was quite used to it.

She took a bite of the cornbread, and asked Shen Rui curiously, "Why didn't you buy food from the small cafeteria?"

Shen Rui just finished eating two potatoes, looked up and said: "Student Zhang Yue, you seem to have misunderstood me, in fact, my family is just an ordinary peasant family, there is no back door, and there are no good conditions."

Of course he understood what the other party meant. From the memory of his predecessor, he knew that the canteen was different from the big canteen and the small canteen.

The large canteen is rationed, and the small canteen can be purchased with a circulation coupon.

And wealthy families naturally have many such circulation coupons, which can be used to purchase many additional supplies.

Fu Yunqing's food is so good, he must have bought it from the small cafeteria.

However, it is impossible for Shen Rui to buy it himself. The family has very little savings and needs to save it for great use.

If he was in the past, he might not be able to calmly tell the real situation at home like this, but after several years of society, he understands very well, don’t pretend to cover up your family environment, it will bring you no glory, all you need to do is Be down-to-earth, work hard, and change your family environment.

Zhang Yue was slightly moved. A high school student at this age is still very vain. Many people are unwilling to say that their family conditions are poor, but this deskmate is outspoken.

"Sorry, then I misunderstood you, it seems that your physique qualifications must be very good." Zhang Yue said sincerely.

Shen Rui nodded, expressing that he didn't care, this classmate was outspoken and would not plot against others behind his back.

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 by themselves in the evening.

At this time, the school was completely dark, and there were no street lights on the road, only the lights from the classrooms in the distance, barely illuminating the road.

On the playground opposite, there are still a few street lights on, and there are still many people 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 directly decided.

"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 dispatch team on weekends." Zhang Yue thought for a while and said.

This is the second time Shen Rui has heard of this concept. There is very little about this concept in his memory. He only knows that the school organizes gifted students and senior students. In a safe area, do gathering and hunting, or go to some village camps to collect supplies.

It is not only the growth experience, but also the full use of manpower.

It seems that Zhang Yue's family is better than his, at least they have more knowledge.

Fu Yunqing nodded, and said to Shen Rui: "Then student Shen, I will go to training with Zhang Yue, you can go to study by yourself."

Shen Rui nodded and left.

Back in the brightly lit classroom, I saw that there were not many people in the classroom.

He glanced at it, returned to his seat, immersed himself in the book, and continued to sort out the memories of this world.

Before dinner, he had roughly browsed through the books on the desk.

He took out a book from it and began to read it emphatically.

The title of the book has only two words - "Geography".

In the high school in his previous life, he remembered very clearly that his college entrance examination did not take geography, history, biology, etc., but only five subjects, mathematics, English, Chinese, physics and chemistry.

However, in this world, "Geography" and "Biology" have become the key points. There are also physics, chemistry and mathematics, but the content has changed, but English and Chinese, he didn't see where the books are...

By the way, there is still an ideological education class on Friday afternoon.

Shen Rui flipped through the "Geography" book carefully, and slowly solved some questions.

The lesson of "Geography" naturally includes astronomy, and the same is true for the geography of the previous life.

In this book, it tells that 15 years ago, there was a sudden change in the sun, the doomsday came, and strange things were rampant.

It took human beings five full years to gradually recover, using the remaining industrial system to build castles in various places to defend against strange monsters.

There is a map of China in the book, with sporadic dots and fortresses on it, and it is now the age of castles.

From south to north, there are hundreds of fortresses in the entire Chinese homeland, with more in the south and fewer in the north.

The standard fortress is 50 meters high, made of cement and reinforced concrete, and 10 meters thick, which can defend against the impact of strange monsters below the fifth level.

The walls of the large fortress are 150 meters high and 30 meters thick.

The walls of the small fortress are 20 meters high and 5 meters thick.

Human beings are now living in the form of fortresses. Human life is humble, but manpower is precious, and every cent cannot be wasted.

This seems to be contradictory, but in fact it is not contradictory. Precious manpower refers to those who can gain a foothold in the wild, that is to say, those who have at least one level of physical skills.

Those who cannot gain a foothold in the wild can only rely on the shelter of the castle. Obviously, the value of manpower is very low. The output of resources in the castle must be limited, and the number of jobs is also limited.

Only the vast wilderness can support the primary industries such as collection and planting that occupy a large area.Relatively speaking, industries occupy less land and can operate within the castle.

Of course, it’s not that no one has thought about building multi-storey greenhouse agricultural buildings in the castle, using electricity instead of solar energy, but firstly, the investment is too large; secondly, any life has the risk of mutation, and the greater the density, the higher the danger of mutation.

Even plants cannot escape this law.

If multi-storey greenhouse agriculture is carried out in a densely populated castle, once mutated plants appear, the harm can be imagined.

You must know that many plants can bloom and have pollen. Once this plant mutates, it will spread rapidly, obliterating the entire castle like a plague.

Several examples of southern castles are given in the book.

There are abundant water sources and convenient hydroelectric power generation. Some people thought of building multi-storey greenhouse buildings with the help of solar lamps. However, there have been several large strange plant disasters because of this.

It erupted suddenly within the castle, spread rapidly, and finally became difficult to defend, and the bustling fortress became ruins.

The most famous one belongs to the "Xiabao Ruins", which is located near the Nanjiang River, where a giant vine monster mutated from a cucumber still stands.

And the tall city walls, combined with some special protective measures, can prevent 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 can survive a lot.

Like coal fields, oil fields, iron ore, and other necessary mineral areas, there are special castles built for protection.

A coal field 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 doomsday world, but growing food on tens of square kilometers of land cannot feed many people.

　I have already signed a contract, and the 2nd update will start tomorrow.There are three updates after the recommendation.
