Before the first tsunami came, Xu Liang came into contact with the key to the Civilization Arena. In a series of coincidences, he acquired it. And in a moment of crisis on a fighter, mastered how to turn it on and use.

But for this key, that is, a string of these 13 precision parts, he didn't figure out what it was at all.

The key helped him improve the sensitivity of his intuition and helped Duan Han improve his rational thinking. All in all, a very powerful key. But what this thing wants to explain scientifically, its origin, and who made it, Xu Liang said that it is very confusing.

Duan Han has also been studying this thing for the past few days, and has come to the conclusion that it is "alien-artificial". Of course, when Sister Duanhan said this conclusion, her expression was quite frustrated, because she couldn't study it, so she had to say why. For those who insist that science can explain everything, this is quite frustrating indeed. And there are so many things to deal with these days, and I don't have time to do this.

Anyway, this thing is useful, and it doesn't cost money, so just use it for the time being.

But now the situation is different, the word spoken by Sister Duanqing hooked up all Xu Liang's memories.

She has a civilized arena?

I have the key!

Isn't this just a pair of CPs?

Xu Liang took out a small string composed of 13 parts, this thing and a rosary can almost be worn in the hand or in the arms, even if you look at it, there is no "key" shape.

Xu Liang asked Duanqing with half confusion and half shock: "So, this maritime city, no, this 'civilization arena' was also built by you?" ”

If it was really made by Duanqing, then Duanqing would be ...... It's awesome!

Duanqing's scientific research strength...... The creation of 'spider dinghies' and 'big ship systems' is at least within the understandable realm of technology. However, this kind of thing that forcibly improves the ability of the individual is still the ability of the brain, and it is not clear to explain it with the scientific method anyway.

Duan Qing replied decisively: "No." ”

Everyone breathed a sigh of relief. It seems that everyone does not want common sense to be subverted.

But the question arises again, if it wasn't made by Duanqing, then who else could it be?

"I don't know." Duan Qing explained, "Do you remember the information I sent you? The location of the large ship system is Kiribati, a Pacific island nation. The main reason for choosing such a place is actually because of this civilization arena. ”

"It's because the Civilization Arena is here that I built the big ship here."

So that's the case?

Xu Liang: "Then what is the purpose of this so-called arena?" Oh, who made this thing? ”

Duan Qing: "I just said, I really don't know who made it here. But I know exactly what it's for. This civilization arena is something that can save lives at the most critical moment of human civilization. And it must be used with a key. ”

"Only a key can open it."

Duan Qing glanced at Xu Liang meaningfully, and continued:

"The key problem is that the keys are issued randomly. In other words, look at luck. ”

"Moreover, the key can improve the ability of the holder, and the improvement is still very large."

"I think that's why you're so powerful and so strong. Maybe that's why my sister was able to discover new mathematical laws and have an absolute advantage in electronic warfare? ”

"Can you tell me how you got the key?"

After listening to Duan Qing's description, Xu Liang told his bizarre experience.

After hearing this, Duan Qing rubbed his head and said, "I can't figure it out." There are so many coincidences. It seems to be really luck. ”

Xu Liang rubbed his chin: "I can't figure it out either." I have a lot of questions, and I feel like you haven't made it completely clear...... Tell me more about it? ”

"Because of the family, because of the special channel...... Forget it, it's another long story. Very, very long, I can tell you. But I think we should get through the biggest tsunami crisis first! I'll talk about the story later. Duan Qing said, and then she continued to add, "After all, there is only a little more than one day left now. ”

"The length of the day, which is based on the findings of surviving scientific instruments, is incorrect. It's possible to delay, but it's more likely to be sooner! ”

"So, we have to prepare for the worst!"

"The final Category 13 tsunami came in a different way than the previous two times."

"According to instrumental observations, in the end, the combustible ice deposits on the seabed will not erupt in small batches as in the previous two times. Rather, it erupted at the same time! ”

"In this way, the tsunami will be at its most destructive. In the corresponding targeted design of the big ship, I have also added some corresponding links. ”

When my sister Duanqing talked about the way to deal with the final tsunami. Xu Liang also really began to investigate the structure of the big ship.

He looked out the window.

Xu Liang looked through the seemingly chaotic but actually regular system outside the window, and his brows furrowed more and more. Duan Han, who was standing on the side, knew Xu Liang very well and knew that he had unparalleled intuition. So Xu Liang's expression is now...... Is it because he sees potential danger?

Could it be that although the 'big ship system' is very strong, Xu Liang still thinks that it can't withstand a super tsunami of this level?

Sister Duanqing continued: "The threat of a tsunami mainly comes from two aspects, one is the lateral impact, like the waves washing onto the shore, it is horizontal, similar to the erosion from the sea to the land, which can knock down objects such as the number of houses horizontally. At sea, that means capsizing the ship. ”

Xu Liang listened to her description, pacing back and forth, his brows furrowed even deeper.

Duan Qing: "Another threat is the impact from the bottom up, like a blast, which is longitudinal. It's like a big bomb underwater, which explodes and pushes the boat out of the water. ”

"For both threats." "I've got it all," she said. The lateral threat can be solved by a sufficient number of thick chain connections, and all the super-mega ships I have built, with useless top measures removed, the deck is completely closed, and there is no fear of water at all. ”

"And there are vertical threats that are also being addressed. Because the large ship system is a spider web, or fishing net structure, most of the longitudinal explosions will pass through the 'mesh', which relieves a lot of pressure on the hull that can withstand the capacity. ”

"So I'm confident."

Duan Qing briefly explained the projections of the large ship system to fight the tsunami. All the officers agreed as if they didn't understand, but Xu Liang, who didn't understand science at all, had become extremely ugly.

The waves outside the porthole were quite intense, while the big boat system was unusually stable. The system, which is formed by the union of countless chains and tens of thousands of huge ships of different sizes, has its own inherent stress, and can cope with the pressure of the waves.

This seems to fully prove the strong practicability of the system built by Duanqing.

However, Xu Liang's face became more and more ugly.

"No way!" He said suddenly.

Duan Qing: "Questions?" ”

"The problem is serious! Your big ship system will fall apart! Xu Liang said solemnly, "You underestimated the destructive power of the final tsunami!" ”
