Chapter 16 The Pain of Breathing (16)

Different from Yu Di's coffin-like shelter, the rebels who occupied the construction site nearly a hundred meters away also included the building to the east.

Although the building itself was not fully enclosed, they did not lack building materials. The man with the horn mask refused to live underground, so they sealed off the upper floors and installed filtering pipes, barely allowing him to wear protective clothing for a long time.

Time stayed inside. He stood in front of the window all day long and looked in the direction of the dungeon without saying a word. His eyes were hidden behind his sunglasses, giving people the feeling that he was making some calculation.

He actually didn't have any calculations. He didn't even think about anything. He was emptying his brain and body. The engineering team recruited a few days ago was dug all the way from the Class B No. 163 underground city along the originally planned subway line.

The underground cities are not isolated entities, but are connected through sealed subway lines. After this engineering team completes the excavation of this section and the closure of the subway entrance, it will enter the Class B where Yu Di stayed before

City No. 164.

Yu Di didn't pay much attention to the distribution of dungeons before. After communicating with Cheng Die, she slowly figured out the levels of dungeons in this world.

There are three levels of underground city construction. The Grade B underground city that Yu Di stayed in before can accommodate a maximum population of 30,000. In addition to basic life facilities, it is also equipped with a research institute and engineering department. The higher Grade A underground city can

With a population of about 18,000, the top scientific researchers are concentrated here, equipped with a large number of weapons and defense facilities, and also has a small underground farm.

That's right, underground farms.

There are seven Class A dungeons in total, and you can tell what kind of people live in them just by thinking about them on your knees.

The deterioration of the environment has made it impossible for crops to grow, but that is for a large area. The Class A underground city retains all the animal and plant sources that humans could collect before the migration. They have arranged for dedicated people to create an environment suitable for their growth and to breed them.

For residents to take food. You want to ask what the animals eat?——Nutritional cakes.

The food and drinks at the bar in the Class B City Research Institute were given to them by Class A City as rewards.

Class C cities are where most people live. The population capacity of Class C cities is more than twice that of Class B cities, but except for residential areas, protective clothing must be worn in other areas. Class B cities also have dining areas.

, you can always get a piece of cake when you are hungry, but there is no such thing in Class C cities. Their nutritional cakes and drinking water are limited to each person.

In addition, Class C cities also have "livestock areas" where genetically modified pigs with extremely short growth cycles are raised. Because of the quarantine area, the livestock sheds are smaller than human residential areas. The fat-headed and big-eared livestock inside eat

After sleeping and eating, they will be slaughtered in less than half a year and transported to Class A cities. There are many people willing to do this job, because every time they are transported, the breeders can take the opportunity to go to Class A cities to see them.

Look, you can even get two pounds of cooked pork.

However, Class C cities do not have research institutes and engineering departments, and they do not have the power to govern independently. The administrator of Class C city is like a supervisor, and must obey the arrangements and orders of Class A city in everything. In contrast, every Class C city administrator

Each city is protected by a corresponding Grade A city, and the manager of a Grade B city with certain autonomy is more like the leader of a small country.

The explosion caused by the fight between the man in the horn mask and the engineering team cut off the communication between the engineering team and the underground city. Without contact in advance, they could not determine the exact location of the underground city platform. If they dug at the wrong angle or height, they would become adults.

They were like criminals. And their supplies were not enough to support their activities for a long time, so the engineering team leader surrendered decisively.

The man in the horn mask took a fancy to the cooperative attitude of the engineering team leader, and generously gave them an isolation vehicle so that they could have a good rest. When he heard that the engineering team's destination was the nearest underground city, the man in the horn mask started to think.

Tell the captain that as long as the engineering team helps him reinforce the ground base and set up basic filtration and purification facilities, he is willing to provide vehicles, weapons and even manpower to send them to the underground city.

The engineering captain is a flexible person. Although he felt that the proposal of the man in the horn mask seemed uneasy and well-intentioned, the defensive strength of the underground city was not something that only a few dozen people could break through. He simply agreed first, hoping to use their power to get through it first.

Let’s get in touch with the dungeon.

Just when they were about to complete the construction, Yu Di and the others also cultivated their plants. But because they could often hear the movement on the surface, they still didn't dare to show their heads. When they saw these people looking like they were about to leave, Cheng Die thought.

Anyway, I have nothing to do. Use this time to test the purification ability of this plant.

So Lanlong and Yanlin worked as coolies again, reopening the sealed ventilation ducts, climbing to the second floor, and moving the observation boxes back to the fourth floor one by one. The place where they lived was packed to the brim, and Mibao had nothing to do with it.

He had room to crawl under the bed all day long, occasionally knocking over an incubator, and had to be taught by Cheng Die for a long time while carrying his slippers.

After moving the plant seedlings from the incubator to the observation box, Cheng Die and Yu Di kept an eye on the data for two months. Until the early morning of that day, the test paper showed that the soil acidity had dropped to 4.2, which was what existed on the surface before the deterioration.

Among plant species, it is possible to

The lowest pH for survival and growth. Cheng Die couldn't hold it back and grabbed Yu Di, who was dozing, and burst into tears. Lan Long was so frightened that she thought she was ill. It was Yu Di who was surprised when he saw the data record in Cheng Die's hand with his sharp eyes.

Tell Lan Long and Yan Lin the good news.

Under the influence of Cheng Die, Yan Lin has completely changed from the "Evolution Party" to the "Purification Party". After witnessing that the surface soil was really changed by this plant, he was so excited that it was unspeakable. This plant was discovered and cultivated by them.

Come out, round up, aren't they the saviors?! His name Yanlin will be written in textbooks, his deeds will be engraved on stone tablets for future generations to learn from, and his appearance will always exist in the memory of mankind.!

While Yan Lin was still dreaming, Cheng Die had wiped away her tears of excitement, found the design drawings of the shelter, and pointed to an experimental field she had originally favored - an abandoned small park across the road.

Cheng Die's plan for this experimental field is quite detailed, but because it is still in ruins, they have to slowly clean it up before they can start the planting plan. The environment in the open air is different from that in the observation box. When the plants are actually moved,

Before planting it in the ground, you need to do an additional air adaptability test. But judging from the situation when Yu Di discovered this thing, it shouldn't be a big problem.

So the first goal now is to drive away those annoying thugs outside.

Yan Lin watched them discuss the plan and suddenly thought of something: "Hey, let me tell you, you guys have been calling 'Youya', 'Youya', doesn't this thing have a name?"

name?

Cheng Die was stunned for a moment. This thing seems to have no name. She looked at Yu Di: "You discovered this thing. Does it have a name? If not, you can come up with one."

Yu Di thought for a while: "Since it looks like a melon and can improve the soil pH, how about it be called an alkali melon?"

Cheng Die was amused by the name for a long time, then patted Lanlong on the thigh: "It's called Jing Gua!"

The second update is here!
