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

"Zero, have you just felt the eyes of others?"

"I have to cooperate with screaming, it's the kind...the kind in the small movie. Since I want to act, I have to act in full."

Zero retreated a little, indicating that he was unwilling.

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

"Ah..." Zhang Ran screamed in pain.

Perhaps, this voice was probably...got to be heard by someone else?

It's almost like this...

Zhang Ran bit his teeth and opened the portal of the sub-space.

His ability is also limited. Although he can open subspace anywhere, he can only maintain access to one door.

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

"How is it?" Zhou Chengfeng hurriedly "swimmed" over.

"It's a coward game, of course I won," Zhang Ran said with a smile, "I cheated on a lot of high-end machinery. Many, many!"

Lin Qiuyue hurriedly participated in the discussion of the expert group, and a surprise voice soon came.

"Really, that machine has been obtained...and that ICP-MS and that high-precision substance analyzer have all been taken out?"

"Are they...n't they ready to develop science?"

"It will definitely not develop anymore. It's a good idea to survive with just 500,000 people. What kind of science will be developed? I guess there are not many places for scientists."

This fact makes everyone feel moved.

The development of science requires a large amount of energy resources. Now, more than 40 million people are backed by the earth, and the development of science and technology is already very difficult.

What's more, there are 500,000 people, a large number of powerful people, and only one small universe.

"Okay, okay, let's not talk about these things for now, do the serious business!"

After a day of design, discussion, and calculation, these experts had almost no rest except for eating.

They completed the general design work at the fastest speed - of course, it was just a shell of the shelter, with no details inside.

And with experience, most of the structures of the "Eden" refuge were copied.

The professor in the lead had red eyes and his voice hoarse: "Time is too tight. I mean, let's first create a small refuge that can live in 300,000 or 500,000 people to appease the army that may riot."

"Let's control the army first."

"Then it will be improved slowly and take three months to build a super-large refuge. The structure of the Garden of Eden can be referenced, but it cannot be completely copied. After all, we have to build a circle."

"The life span of the earth is still three months, so you can't be too anxious."

"You are right." Zhang Ran nodded.

"Your Highness, there is another question, which is very important." Professor Huo asked suddenly.

"you say."

"How big can the space door you can open?"

Zhang Ran was silent for a moment and said, "A real world door is needed as a carrier. The bigger the real world door is, the bigger the space door I can open."

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

"If I draw a circle on the equator and think that this circle is a door, can you bring the entire earth into subspace? What other refuges will be created in this way?"

Zhang Ran was stunned for a moment and was stopped directly.

This...what is this?

But it is another very meaningful question.

To bring the entire earth into subspace, there is no need to worry about resource difficulties at all.

You should know that the earth's mass is 60 trillion tons, and it is complete whether it is oxygen, water, metal, coal, or geothermal heat.

No matter how strong Zhang Ran's ability to create is, compared with the earth, it is just a cow's hair.

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

Because, he just asked how to expand the space gate.

[In your era, the study of dimensions is limited to the primary stage. If you want to open a larger space door, you need to consume additional creative energy.]

The space door below 100 square meters is free.

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

If it exceeds this area, a certain amount of creative energy must be maintained.

A space gate with an area of ​​one square kilometer requires 1 o'clock creative energy and can only last for one hour.

And so on, a space gate with an area of ​​2 square kilometers requires 2 points of creation energy.

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

Zhang Ran shook his head: "No, it can only be maintained at most 100 square meters of doors. No matter how big the door is, it will cost an extra cost."

"No..." Professor Huo Dong frowned.

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

Zhang Ran nodded: "This should be OK."

Huo Dong said: "It's very good, it's much easier to transport supplies."

Next, it's time to do the serious business.

"Your Highness, you first follow this drawing to create two symmetrical shelters, 200 kilometers apart, connect them with carbon nanotubes, and then rotate them to make the angular velocity reach 0.01rad/s."

Zhang Ran looked at the drawings and found that humans had created a refuge that could live in 500,000 people, so this drawing was obtained after the improvement of the ready-made product.

In fact, it is two super-large cages, connected by ropes, and rotated around the center point.

Each refuge has a length of up to 2.8 kilometers, a width of 1.6 kilometers, a height of 500 meters, and a total living area of ​​40 square kilometers. In theory, it can 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 areas, dirt treatment areas, industrial areas, commercial areas, entertainment areas, power areas, etc.

A single 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 refuges are only part of the total ring and one percent of the total construction volume."

Zhang Ran nodded: "I understand, it's better to be early than it is so late, so let's start now."

【create……】

Silently recite in my heart and follow the design drawings.

A white big guy with a trace of curve was soon created in the void.

This white paint has a certain warmth effect.

Then there is the creation of internal structure.

Since all matter is piled up with various materials, even if this thing has never appeared in human history, it will not affect Zhang Ran's creation.
Chapter completed!
