Global Disaster: I have a dungeon

Of course, Liu Yue and Liu Yiyi knew what Liu Chen said.

That is to bring about 200 million residents in the satellite city to space to avoid refuge!

What is 200 million?

How old is the refuge?

They didn’t even dare to think about it.

“Brother, don’t you kidding!”

Although he knew that Liu Chen had some secrets, Liu Yue was still incredible.

Liu Chen smiled, and it meant that it was self -evident.

Immediately, he didn’t talk nonsense, and opened the system directly.

【graduate School! .

[Level: 23! Upgrade system currency required for the next level: 150000,000! Need the dungeon level: 28! .

[Space Technology! .

[Lunar probe, research cost: 2000 system currency! .

[Mars guess, research cost: 20000 system currency! .

[Saturn detector, research cost: 80,000 system currency! .

[Neptune probe, research cost: 100000 system currency! .

[Solar space detector, research cost: 500,000 system currency! .

[Galaxy space detector, research cost: 50,00000 system currency! .

[Small refuge module x1, research cost: 500 system currency! .

After the last option came into Liu Chen’s eyes, Liu Chen looked at him.

But then his brows sank.

Is this a bit cheap? Intersection

But the more cheap this kind of thing, the more Liu Chen is, the more you have. After all, it is where countless people have been avoided in space. There is no hidden danger. It does not immediately study, but open its attribute panel first.

[Space refuge module! .

[Level: No study! Studies require system currency: 500! .

[Effect: Different modules are required to be stitched into a space shelter! .

Seeing this, Liu Chen understood.

It is considered to understand why there must be a “X1” logo behind this option.

Why is it so cheap!

It turns out that this needs to be stitched!

But think about it, and right, a single launch helps to do greater. If the entire launch is launched, the carrier rockets needed

I’m afraid it’s scary.

So Liu Chen asked: “How much is the space shelter that is stitched by the 10 different space shelters modules? How many people can support?”

The system answered: “The internal space of 1000 cubic meters! It can accommodate 500 people at the same time!”

Liu Chen calculated carefully: “That means that 5000 system currency can make 500 people, and the 200 million people need 2 billion system currency.”

Liu Chen nodded.

It is enough to set up a system currency for refuge, which is enough, and it is more cost -effective.

However, it doesn’t work alone.

There must be sufficient supplies, sufficient water sources, sufficient oxygen, exhaust system, drainage system, etc.

Otherwise, it won’t live for a few days even if you get it up.

Do these things have to expand room again?

After expansion, do you need to install other equipment?

How much do you need to expand for a month on it?

How much system currency is consumed?

These are all problems!

Liu Chen had no bottom, and there was no specific number.

After thinking about it, Liu Chen directly asked the system.

The system’s answer is very general, and he immediately sends a specific parameter to Liu Chen.

Including how much oxygen is equipped, how much space is occupied, how much material is equipped, how much space is, how much water is equipped, how much space is

Do not worry about exhaust and drainage systems.

For a bit of roughly, to make the entire space shelters be fully built, it costs about 5 billion system currency.

Then Liu Chen had another account.

Is it a good job of living in the dungeon? Still entering space!

If you live in the dungeon, spend a system currency to open the oxygen dismissal station!

That system currency is quite amazing.

Fortunately, when the previous section of oxygen concentration is not very high, there is no need to start the oxygen dispellation station.

But after a long time, as the oxygen concentration increases.

That must be required, so don’t ask.

If you enter the space refuge, you will pay at one time.

Of course, he also thought that satellites could be launched when the blue star oxygen concentration reaches a fatal critical point.

But this method quickly rejected.

After all, in his opinion, it is really tantamount to finding death!

In the case, Liu Chen finally determined that the expenses of these two methods were almost the same.

But relatively speaking, it is safer to enter the spatial refuge.

After all, there is no air in space, don’t worry about oxidation.

“Then choose to build a space shelter!”

With attention, Liu Chen just chose to act.

“Study the module of the spatial refuge!”

【Ding! .

[I have received the instructions from the host, and I am studying the module of the Space Shelter X1]

[The research of the module X1 of the Space Fair is successful! Is it made immediately? .

“yes!”

After studying more than 100 space shelters and manufacturing in a row, Liu Chen began to make rockets again!

It is used to carry the module levels of each space shelter to enter space.

After everything was ready, Liu Chen called Liu Yue, Liu Yiyi, and Fu Hao to her.

Tao: “I want to build a space shelter, you should be clear.”

“Now, I let you go to space for the first batch, do you have no opinion?”

Liu Yue, Liu Yiyi, and Fu Hao glanced at each other, and their expression was dull.

Really said to do it?

“no problem!”

Fu Hao’s first statement, he said, “However, this time this time is too dangerous, let me go alone first, Yueyue is still the two of Yiyi, and then go behind.”

Liu Yue said: “Why? My dream is your first Tang Guo astronaut! Now your dreams will become a reality soon, why should you stop me?”

That tone sounded a little unhappy.

Liu Yiyi also said: “During this time, my results in the driving test simulation base are not worse than you!”

Seeing the tone of the two, Fu Hao couldn’t help scratching his head.

“Isn’t this afraid of something wrong?”

Liu Chen laughed.

Is there a risk of things produced by the system?

That must be there!

Immediately: “I’m not let you go to be a cannon fodder!”

“This time let you go first, there is a task. After there, I will soon launch a group of people up. Fortunately Never open, do you understand? ”

“This time, it is related to the survival of human beings, and there must be no splits in the Space Shelter!”

When the three heard, their eyes were bright.

I ca n’t help for such a long time, and now I finally have a chance to appear!
