Doomsday Bunker Upgrade

A silver dome stands in the darkness, and the curved dome structure reveals light from the inside, lighting up the entire dome.

Although the light is not very obvious, and the thickness of the dome also restricts the penetration of internal light, this still makes the dome like a lighthouse in the dark, guiding passers-by from afar to return home.

However, at this moment, a meteor that was far brighter than the dome streaked across the sky.

The friction between the star and the air ignited the air, burning a bright light, like a sun rising in the dark night, illuminating the dark sky.

The meteor streaked across the sky and fell towards the dome, as if aiming at the dome deliberately, trying to smash it down.

As the meteor continued to fall, it finally hit the dome, broke through the outer heat insulation material, airbag layer and steel structure support of the dome with irresistible momentum, and fell into the interior of the dome.

However, when the meteor fell into the dome, everything seemed to be paused and stopped.

"It seems that after the diameter of the meteorite exceeds one meter, its destructive power is enough to destroy the current dome city." Chen Xin's figure appeared on the dome where the meteorite penetrated, looking at the penetrated place and around the breach Chen Xin frowned as the flames ignited.

This is the virtual projection he made in the holographic image room of the shelter, through virtual images to simulate the possible damage caused by the meteorite hitting the dome.

Chen Xin simulated the damage caused by meteorites of various sizes hitting the dome, from the smallest one with a diameter of one centimeter to the meteorite with a diameter of one meter just now, one by one meteorites just hit the simulated dome directly.

However, through testing, Chen Xin discovered that the meteorite did not cause too much damage to the dome itself.

Even when the meteorite with a diameter of one meter hit the dome just now, it did not cause too much damage to the dome. It just caused all the EFTE airbags within a radius of 50 meters around the impact point to be squeezed, resulting in a It's just a breach of about five meters.

This is not a particularly serious damage to the dome itself, which has a diameter of five kilometers.

Although it is necessary to replace all the EFTE airbags within a radius of at least 60 meters around the impact point, and replace the steel structure support within a radius of at least 100 meters below, the damage is still not very serious.

However, for the dome city itself, a meteorite with a diameter of one meter, the damage caused by the impact is enough to destroy most of the city.

"So there is no problem with my thinking, but the city itself cannot withstand this kind of series of impacts." Chen Xin straightened his thinking, and recorded the test results of the last impact in his experiment notebook.

The purpose of Chen Xin's test is mainly to test whether the structural support inside the EFTE airbag that he thought before can enhance the defense performance of the dome.

After testing, Chen Xin came to the conclusion that if the meteorite was not large, then doing so would indeed help maintain the structure of the dome itself, and would not break a large hole due to the impact.

This is mainly because during the impact process, the dome will be squeezed by the impact of the meteorite impact. The closer the EFTE airbag is to the impact point, the easier it is to be crushed. Under such circumstances, if there is a support structure inside, it can undoubtedly maintain the airbag. The general shape of it will not collapse due to being squeezed.

Of course, the support structure also has a limit. As the size of the meteorite grows, the area being squeezed becomes larger and larger, and the closer to the impact point, the more serious the damage to the airbag will be. Even the support structure itself will crushed.

But on the airbag that is a certain distance from the impact point, the support structure has played a very good role. Even if the airbag is squeezed, the support structure can still maintain the shape of the airbag without collapsing.

Therefore, this method of erecting supports inside the EFTE airbag can indeed enhance the structural strength of the airbag itself, but the defense against meteorites has not been greatly improved.

But this is normal. After all, it was a meteorite, not anything else. The force generated by the impact was enough to penetrate the main armor belt of the battleship. Even if Chen Xin laid a layer of steel plates on the dome, it should still be penetrated. .

Chen Xin's original idea was to use the dome as a buffer layer, so that the force of the meteorite hitting the ground would not be so great.

But after testing, he found out that this doesn't actually have much effect.

Although the dome does act as a buffer to a certain extent, for meteorite impacts, when the meteorite can penetrate the dome and hit the ground, the meteorite itself, which can be greatly reduced in impact, will not cause too much damage, but will cause a large area. Destroyed meteorites can still cause great damage even if their power is reduced.

What's more, when the power of the meteorite reaches a certain level, it can directly destroy the entire dome city, but the dome itself is just knocked out of a big hole.

According to this test, Chen Xin came to the conclusion that it is necessary to strengthen the strength of the airbag, but it is not as reliable as developing a city-level shield to rely on it to resist the impact of meteorites.

After sorting out his thoughts, Chen Xin turned off the projection in the holographic image room, restoring the place to its original appearance, and was about to leave for a rest when he noticed Qin Lan standing there at the door.

"What's the matter, Alan?" Chen Xin looked at Qin Lan standing at the door with her arms folded, and asked her, "What do you need from me?"

"I can't find you if I have nothing to do?" Qin Lan replied to Chen Xin, walked towards him, and asked him: "I saw you doing experiments, that is the dome city to be built?"

"Yes, what's the matter?" Chen Xin wondered why Qin Lan would ask this question.

"Then when the city is built, can we move there?" Qin Lan looked at Chen Xin expectantly, bit her lip before continuing: "I'm thinking about our future, if we have children, it's impossible Let the child still live underground like this?"

"Child?" Chen Xin couldn't help thinking when he heard Qin Lan say that.

I have to say that Qin Lan raised a very realistic question.

Although the relationship between Chen Xin, Qin Lan and Mo Qingyan is very delicate, after all, all three of them want to have children in the future.

And having a child, the issue of raising the child in the future is a problem that must be considered.

It's just that Chen Xin hasn't thought about it carefully. He thought about it and said to Qin Lan: "Moving to live in a new city is not a big problem. But how did you think about your child?"

"I..." Qin Lan blushed and didn't know how to answer, so she simply hugged Chen Xin's neck and kissed his lips.
