Doomsday Fast Travel: Kill That Black Butterfly

Chapter 16 The pain of difficulty breathing (16)

Unlike Yu Di and his 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 in the horn mask refused to live underground, so they sealed off the upper floors and added filter ducts, barely enough to keep him inside for a long time in a hazmat suit.He stood in front of the window all day long and looked in the direction of the dungeon without saying a word, his eyes hidden behind the sunglasses, giving people a feeling as if he was planning something.

He didn't actually have any calculations.He didn't even think about it.He is emptying his mind and body.The engineering team recruited a few days ago was dug all the way from the No. 163 underground city of the second level along the originally planned subway line.The underground city and the city are not isolated individuals, but are connected through closed subway lines.After the engineering team completes the excavation of this section and the closure of the subway entrance, they will enter the B-level No. 164 city where Yu Di stayed before.

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

There are three levels of dungeon construction. The level B dungeon that Yudi stayed in before can accommodate a maximum population of [-]. In addition to basic life facilities, it is also equipped with a research institute and engineering department.The higher Grade A dungeon can accommodate a population of about [-]. The top scientific research personnel 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 Grade A dungeons in total, and you can tell what kind of people live in them with just your knees.

Environmental degradation makes it impossible for crops to grow, but that is for large areas.The Class A dungeons keep all the animal and plant sources that humans can collect before the migration, and they arranged for special personnel to create an environment suitable for their growth and breed them for the residents to feed on.What do you ask animals to eat? ——Nutritional cakes.

The food and beverages at the bar in the research institute of the second-tier city were given to them by the first-tier city as a reward.

And the C-level city is where most people live.The population capacity of Class C cities is more than twice that of Class B, but except for residential areas, protective clothing must be worn in other areas.There is also a dining area in the second-tier city, and you can get a piece of cake whenever you are hungry, but there is no such thing in the third-tier city. Their nutritional cakes and drinking water are limited to each person.

In addition, there are "livestock areas" in Grade C cities, where genetically modified pigs with a very short growth cycle are raised.Because of the quarantine area, the barn is smaller than the human living area.The fat-headed livestock inside will be slaughtered in less than half a year after eating and sleeping, and transported to the first-tier city.There are quite a few people who are willing to do this job, because every time they transport, the breeders can take this opportunity to visit the first-tier city, and even get two catties of cooked 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 a C-level city is like a supervisor, and has to obey the arrangements and orders of the A-level city in everything. In contrast, every C-level city has a corresponding A-level city to protect, and the B-level city with a certain degree of autonomy manages People are more like the ruler of a small country.

The explosion between the man in the horn mask and the engineering team cut off the connection between the engineering team and the dungeon. Without prior contact, they could not be sure of the exact location of the dungeon platform. A class of sinners.And their supplies were not enough to support their activities for a long time, so the engineering captain decisively surrendered.

The man in the horn mask took a fancy to the cooperative attitude of the engineering leader, and generously gave them an isolation vehicle to let them have a good rest.Hearing that the destination of the engineering team was the nearest dungeon, the man in the horn mask began to think about it and told the captain that as long as the engineering team helped him strengthen the ground base and get the basic filtration and purification facilities ready, he was willing to provide vehicles and weapons. Even the hands, send them to the dungeon.

The engineering captain is a person who can bend and stretch. Although he feels that the man in the horn mask seems uneasy and kind, but how can the defense of the dungeon be broken by dozens of people in this area?Simply, he agreed first, and wanted to use their influence to contact the dungeon first.

Just when they were about to complete the construction, Yudi's plants were also cultivated.But because they could often hear the movements on the surface, they still didn't dare to stand up. Seeing these people looking like they were about to leave, Cheng Die thought that they were idle anyway, and used this time to test the purification ability of this plant.

So Lan Long and Yan Lin worked as coolies again, reopened the sealed ventilation ducts, climbed up to the second floor, and moved the observation boxes back to the fourth floor one by one.The place where they lived was packed to the brim, and Mi Bao had no room to have fun. He crawled around under the bed all day, and occasionally knocked over an incubator, and Cheng Die had to educate him with slippers for a long time.

After moving the plant seedlings from the incubator to the observation box, Cheng Die and Yu Di stared at the data for two months straight.Until the early morning of that day, the test paper showed that the soil acidity had dropped to 4.2, which is the lowest pH that can survive and grow among the plant species that existed on the surface before the deterioration.Cheng Die couldn't hold back, and she grabbed the dozing Yu Di and burst into tears, scaring Lan Long into thinking she was ill. It was Yu Di who saw the data record in Cheng Die's hand and told Lan Long the good news. Long and Yan Lin.

Under the influence of Cheng Die, Yan Lin has completely changed from an "evolutionary party" to a "purification party".After witnessing that the surface soil was really changed by this plant, he was so excited beyond words.This plant was discovered and cultivated by them, rounded up, aren't they the saviors? !He said that Lin's name will be written in textbooks, his deeds will be engraved on stone tablets for future generations to learn, and his appearance will always exist in human memory.!

While Yan Lin was still fantasizing, Cheng Die had already wiped away the tears of excitement, found the design drawings of the shelter, and pointed to a piece of experimental field she had hoped at the beginning—it was 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 clean it up slowly before starting the planting plan.The open-air environment is different from the environment in the observation box. Before the plants are actually transplanted into the ground, an additional air adaptability test must be done first.But judging from the situation when Yudi discovered this thing as a child, 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 their plans, and suddenly thought of something: "Hey, let me tell you, you guys have always called 'Young Ya', 'Young Ya', doesn't this thing have a name?"

name?

Cheng Die froze for a moment.This thing does not seem to have a name. She looked at Yu Di: "You discovered this thing. Does it have a name? If not, please choose one."

Yu Di thought for a while: "Since it looks like a melon and can increase the pH of the soil, why not call it a melon?"

Cheng Die was amused by the name for a long time, and then slapped Lan Long on the thigh: "It's called Alkaline Gua!"

　The second one is here!
