This coma was another three days. Pen, fun, pavilion www. biquge。 info

And in three days, the underground world of the new world has undergone tremendous changes.

The nineteen-meter underground space opened up by Li Guan was successfully planted with crops by the logistics team.

Nineteen meters underground, this depth, humidity and environment, it stands to reason that no plants can be grown, let alone crops.

However, in today's logistics group, there is no shortage of experts and doctors, and there are already ways to overcome these problems that are not problems at all.

Not warm enough underground?

It doesn't matter, as soon as the exit is blocked, a few boilers are burned inside, and even the greenhouse is not used, it directly becomes stuffy, and the temperature rises instantly.

No sunlight underground?

What is sunlight? It's nothing more than ultraviolet rays, and photosynthesis.

The Cuihu Steel Mill immediately produced a batch of ultraviolet lamps, the strength of which can be adjusted according to the environment, in addition to the white light lamps that imitate the sunlight throughout the underground space. Illuminate the entire underground space 24 hours a day, illuminating as bright as day, so that this underground space is daytime 24 hours a day.

In the midst of the lights, turn on the UV lamps from time to time. The external environment was immediately imitated. If I don't tell you, you won't even know that this is 19 meters underground.

There's nothing that the logistics department can't do.

Especially after being kidnapped by Li Guan and a few scientists came, Cuihu Steel Mill completely soared into an immortal. You can make anything high-tech.

A total of 10 areas have now been developed underground.

The first floor is nine meters underground, and that area is the first underground area opened up by Li Guan.

Now all the people who live here are the old, weak, sick, disabled women and children, and they live very well, and they even have the illusion that this is actually the outside world. The only difference is that one can't see the blue sky when he looks up.

Li Guan created various districts, just rough houses. And after the engineers and mechanics of the logistics team came in, this was completely renovated.

Throughout the first zone, there are vents that have been carved out everywhere.

These vents are very complex and are not carved all the way up. Rather, use PVC pipes to form a ventilation vein.

The logistics team built the vents as if they were underground drainage systems. The effect is remarkable.

They inserted a PVC pipe into the wall on the left as a place to exhaust the exhaust gas, and there was an exhaust fan at the mouth to continuously extract the internal air and exhaust it out.

There are exhaust vents in every room throughout the first zone, and the pipes converge in the dirt into the large pipes before they emerge from the ground. And the exhaust vents on the ground are all in some geographical dead ends, not to mention people, and there are some places where rats can't go.

The same is true for the air intakes, where a large main pipe runs from the ground to the ground, and when it reaches the first zone, it is dispersed into many PVC pipes, which are distributed from different places into the various rooms.

In order to allow fresh air to come in, there is a core heart in the main pipeline, which is the silent high-power exhaust fan of the battery developed by Cuihu Steel Mill.

After the air is pumped into the main pipe and dispersed into each room, there are also small silent exhaust fans inside the walls of each room.

And in order to prevent the outbreak of zombies in the outside world, there will be bacteria in the air. This main exhaust duct is also full of science and technology.

There are many air filtration systems, and in addition to them, liquid filtration systems are also built.

They set up a cistern, and the cistern was full of disinfectant. The air entering the first zone must first pass through the air filtration system, the precision filtration system, the disinfectant pool filtration system, and the precision filtration system.

Then they will be drawn into the first section. In order not to let people smell the disinfectant water, there are air purifiers and air fragrances in each PVC pipe.

Therefore, the entire space of the first district is ventilated everywhere at all times, and the air is extremely fresh at all times.

Those who lived in the first district in advance only felt that this was simply the living environment that was infinitely close to the era of peace after the end of the world.

This is the most important part of the logistics department's setting - the environmental atmosphere.

Since it is an underground kingdom, although it is underground, it is a kingdom. Since the kingdom is the kingdom, everything must develop according to the aspects that are most suitable for life.

Now that the zombies have not swept over, everyone has time to develop the environment. In the future, we must make plans to live underground for a long time, and the environment cannot be ignored.

Not to mention the living environment, all the live animals in Yunnan have also entered the 19-meter animal husbandry area, and the air level in the breeding area is also the appearance of the first area. This is due to the fact that the pipes of the exhaust system are extended, which by the way enters the livestock area.

These animals live in a particularly hilarious way. Happily eating feed every day, playing happily every day, and then being slaughtered.

There are special biologists in the logistics department who are responsible for them around the clock, and scientific breeding allows them to reproduce quickly, grow quickly, and produce meat with high quality.

The water source is a bit complicated, because the logistics department directly opened up the underground river and pumped it directly into the underground purification plant. Evolved into tap water, which enters various areas through water pipes.

It's a difficult project and it's still not finished.

In short, everything is basically in place.

All the population of the New World can move into the underground at any time. The environment may not be good in the first few months, because in addition to the first area and the breeding area, other deeper areas have not been renovated, and there are no exhaust ducts, so you may have to go to the first area every once in a while to breathe.

Now that the zombies have not arrived, it has given the logistics team a lot of time to buffer, and they are determined to set up the underground kingdom before the zombies arrive.

Li Guan woke up, and there was no doubt that the island had expanded again.

His earth-walking skills have evolved again.

Zhang Wenjing asked nervously, "How is it?" ”

Li Guan leaned in her ear and whispered, "I can reach a depth of about forty meters now." The sensing range is about 1,000 square meters. ”

Zhang Wenjing exclaimed: "It's so powerful, how can you jump and evolve?" ”

Li Guan shook his head: "I don't know either." But I feel like every time I evolve, my abilities increase exponentially. I think that now, except for the Yangzhou Alliance, I can provoke the whole world. ”

Zhang Wenjing gasped: "A thousand square meters...... Wouldn't you be able to carve out a space of 5,000 square meters in a matter of seconds? ”

Li Guan smiled: "I'm going to go to Yuxi to show my strength." ”

"Why do you want to go to Yuxi?"

"Kunming is about to be hollowed out by me, so I can only change positions. This time, I prepared to dig out a five-square-kilometer training ground 40 meters underground in Yuxi. ”

Li Guan's eyebrows fluttered and said. (To be continued.) )
