Start a Subspace

Zhang Ran closed the door of the room and let go of the two girls.

Zero, did you feel the eyes of others just now?

I have to scream in conjunction with it, that kind of... the kind in a small movie. Since you want to act, you have to complete it.

Zero stepped back a little, expressing his reluctance.

Lin Qiuyue stared at the data on the phone screen, raised her head expressionlessly, and kicked Zhang Ran's calf.

Ah... Zhang Ran cried out in pain.

This voice, perhaps, probably... spread out and was overheard by others, right?

It's almost like this...

Zhang Ran bit the bullet and opened the subspace portal.

This ability of his is also limited. Although the subspace can be opened anywhere, it can only maintain the entry and exit of one door.

If the second door is opened, the first space door will disappear.

How is it? Zhou Chengfeng hurriedly swimmed over.

The coward's game, of course I won. Zhang Ran said with a smile, I cheated a lot of high-end machines. A lot, a lot!

And Lin Qiuyue hastily participated in the discussion of the expert group, and soon there was a voice of surprise.

Really, that machine is actually in hand... that ICP-MS, and that high-precision material analyzer, are they all taken out?

Aren't they... aren't they going to develop science?

It's definitely not going to develop. There are only 500,000 people. It's good to survive. What kind of science is there to develop? It is estimated that there are not many scientists.

This fact made everyone feel emotional.

The development of science requires a lot of energy resources. With a population of more than 40 million and the backing of the earth, the development of science and technology is already very difficult.

What's more, with 500,000 people, a lot of dignitaries, and only one small universe.

Okay, okay, let's not talk about this, let's do business!

After a day of design, discussion, and calculation, these experts hardly had any rest except for meals.

They completed the general design work as quickly as possible—of course, it was just a shell of the shelter, with no internal details at all.

Moreover, with experience, most of the structure of the Eden shelter was copied.

The leading professor's eyes were red and his voice was hoarse: Time is too tight. What I mean is, let's create a small shelter that can accommodate 300,000 to 500,000 people to appease the army that may riot.

Let's take control of the army first.

Then slowly improve and spend three months to build a super-large shelter. The structure of the Garden of Eden can be used as a reference, but it cannot be completely copied. After all, we have to build a circle.

The life of the earth is still three months, and there is no rush.

That's right. Zhang Ran nodded.

Your Highness, there is one more question, which is very important. Professor Huo asked suddenly.

you say.

How big is the space door that you can open?

Zhang Ran was silent for a moment, then said: A door of the real world is needed as a carrier. As big as the door of the real world is, the door of space I can open is as big as it is.

Professor Huo asked: What is the specific definition of the door to the real world?

If I draw a circle on the equator and think this circle is a door, can you bring the whole earth into the subspace? In this way, what kind of shelter will be created?

Zhang Ran was stunned for a moment, and was immediately stopped by the question.

This... what is this?

But it's an interesting question.

Bringing the entire earth into the subspace, there is no need to worry about resource shortages at all.

You must know that the mass of the earth is 60 trillion tons, whether it is oxygen or water, or metal, coal, and geothermal heat, they are all complete.

No matter how powerful Zhang Ran's creation ability is, it is nothing compared to the earth.

But soon, he realized that this was impossible, at least for now.

Because, he just inquired about how to expand the space door.

[In your era, the study of dimensions is limited to the initial stage, and to open a larger space door, you need to consume additional creation energy. 】

Space doors under 100 square meters are free.

That is, the area of ​​10 meters * 10 meters, more flexible can also be 25 meters * 4 meters.

If it exceeds this area, a certain amount of creative energy is required to maintain it.

A space gate with an area of ​​one square kilometer requires 1 point of creation energy, and it can only last for one hour.

By analogy, a space gate with an area of ​​2 square kilometers needs 2 points of creation energy.

The radius of the earth is 6371 kilometers, and the cross-sectional area is about 120 million square kilometers, which requires 120 million creation energy, so it is impossible to directly take the earth into it.

Zhang Ran shook his head: No, you can only maintain a door of 100 square meters at most. No matter how big the door is, it will cost extra.

Can't you... Professor Huo Dong frowned.

There is another question, can the space gate be set anywhere in the subspace?

Zhang Ran nodded: This should be possible.

Huo Dong said: Very good, it's much easier to deliver supplies.

Next, it's time to get down to business.

Your Highness, first, according to this blueprint, create two symmetrical shelters with a distance of 200 kilometers in between, and connect them with carbon nanotubes, and then let them rotate so that the angular velocity reaches 0.01 rad/s.

Zhang Ran looked at the blueprint. Human beings have already created a refuge that can accommodate 500,000 people. Therefore, this blueprint is an improvement of the ready-made product.

In fact, it is two super-large cages, connected by ropes, which rotate around the central point.

Each shelter has a length of 2.8 kilometers, a width of 1.6 kilometers, a height of 500 meters, a total living area of ​​40 square kilometers, and can theoretically accommodate 500,000 people.

The mass of a single shelter is as high as 800 million tons, so the connected carbon nanotubes are also extremely thick. Of course, there are certain structural divisions inside the shelter: residential area, sewage treatment area, industrial area, commercial area, entertainment area, power area, and so on.

Each shelter has the ability to survive alone, even if one of them has a big problem, it will not affect the operation of other shelters.

And these two shelters are only part of the total circle, one percent of the total project volume.

Zhang Ran nodded: I understand, so late is worse than early, let's start now.

【create……】

Think silently in your heart, follow the design drawings.

Soon a big white guy with a slight curvature was created in the void.

This layer of white paint has a certain thermal insulation effect.

Then there is the creation of the internal structure.

Since all substances are made of various materials, even if such a thing has never appeared in human history, it will not affect Zhang Ran's creation.

Half an hour later, a large shelter appeared in the void.
