"I know you're not interested in science." Duan Qing said, "I also know what questions you are interested in. ”

"You must be curious to know how strong a 13-magnitude tsunami really is."

"I think I can help you build a real idea of the strength of a Category 13 tsunami. In this way, you will have a minimum of mental preparation for what will happen after the tsunami. ”

"Before describing its intensity, we might as well evaluate the strength of nuclear weapons. It is used as an analogy with the intensity of a tsunami. ”

"Nuclear weapons are the most powerful weapon that mankind can build, and they are the most powerful means of changing the environment that mankind has mastered. The strength of nuclear weapons is naturally very strong, for example, you now have a nuclear weapon in your hands, and you have a way to control its launch, which is enough to destroy the structure of a large ship. I had no choice but to come over obediently. ”

"But how does the strength of nuclear weapons compare to the strength of a tsunami?"

"Let's start by comparing it to the famous Indian Ocean tsunami that occurred in 2004. The Indian Ocean tsunami was triggered by an earthquake, and if it were to be detonated by explosives, it would require the consumption of 35 billion tons of TNT-equivalent explosives to achieve it. ”

"Yes, you heard it right."

"35 billion tonnes of TNT equivalent."

"And the total, peak stockpiles of nuclear weapons in the world...... Only 18 billion tonnes of TNT equivalent (1986)! ”

"The most powerful bomb that man can make, the Tsar Bomba, a large bomb with a yield of 50 million tons made by the mighty northern Slavic peoples, if it were placed on the bottom of the Indian Ocean. I'm afraid it will only set off small waves on the shore. ”

"You are too superstitious about nuclear bombs, and think that they are the strongest combat power that mankind has in their hands. However, in relation to nature itself...... Nuclear weapons, not a thing. ”

"It is true that if nuclear weapons were to explode all over the world, it could destroy human habitation, but that would only be a sequelae of radiation. The earth doesn't care at all, and for the earth, that little equivalence is like tickling. ”

"Let's repeat that if all the world's nuclear weapons explode at once, doubling that energy will only trigger a tsunami in the Indian Ocean."

"And the 2004 Indian Ocean tsunami was only a Category 5 tsunami, to be exact, a Category 4+."

"For each level of a tsunami, the energy released quadruples, which means. A Category 13 tsunami, a tsunami with waves of kilometer heights, is about 200,000 times more energy than the 2004 Indian Ocean tsunami! ”

"200,000 times!" Duan Qing's tone gradually became excited. and Duanhan, as long as the two scientist sisters talk about numbers, their emotions will become excited.

"Do you know what this concept is?"

"This means that this energy can make everyone on the earth boil 10,000 tons of boiled water, which means that 100,000 tons of matter are all converted into energy, and it means that all human beings in the world continue to develop according to the current electricity consumption, the sum of the energy produced in 1,000 years, and the terrifying ability to release in just a moment!" She said excitedly.

"You may think that human civilization is very strong."

"But human civilization is too weak in the face of nature."

"You think that human civilization can destroy the whole world, but human beings are still six or seven orders of magnitude away from mastering the energy to cause a 13-magnitude tsunami."

"It's not six or seven times, it's six or seven orders of magnitude!"

"That's 100,000 times - 1 million times the difference!"

Xu Liang listened to Duanqing Biao's data silently, and his heart was full of emotion.

He is a data-insensitive person. This complex conversion of TNT equivalents is too difficult for Xu Liang to understand.

But this does not prevent him from understanding the relationship between the strengths and weaknesses of these concepts.

The "nuclear weapons", the most powerful combat power that mankind can build, are still far from the Indian Ocean tsunami; And the Indian Ocean tsunami, which seems to us to be already devastating, is not even scum compared to the upcoming Category 13 tsunami.

Xu Liang not only grasped this relationship, but also keenly noticed a keyword that Duanqing had mentioned several times:

Human civilization.

It's not a word that can be used casually.

If the word is used repeatedly, it probably means one thing - she wants to use the word "human civilization" in contrast to other words.

And what?

What words can be compared with the four words of human civilization?

At this moment, Xu Liang suddenly thought of the mysterious key he obtained, which allowed him and Duan Han to obtain a huge key to improve their abilities. The key has a strange name, and the word "civilization" is also included in the name.

The key to the arena of civilization.

Human civilization, the arena of civilizations......

Xu Liang felt that he had faintly grasped something.

"Do you want to say ......," he asked tentatively.

Duanqing nodded, and then his words continued: "Your intuition is very sharp, you feel that something is wrong, but you can't say what is wrong, right?" ”

Xu nodded.

"Let me be clear about what is wrong: the scientific cause of the Category 13 tsunami has been studied. And that's shown in my sister's research, my research, and the study of the National Academy of Sciences – a one-time burst of fossil fuel reserves on the ocean floor that could be used by humans for thousands of years. ”

"But the question of who lit the fire seems to have never been answered."

"That's right!" Xu Liang slapped his thigh, "You hinted so much in front of you, do you want to say ......?"

"Hmm. That's what I want to say. Duan Qing said, "It's not people who light the fire." ”

"It's not you, it's not me, it's not any conspirator, terrorist."

"Nor is it human civilization."

"Because the nuclear bomb, the strongest weapon that human civilization can make, can only release a pitiful amount of energy, and human civilization is far from being able to grasp the energy released by causing a level 13 tsunami."

"Far from it!"

"Did you know that even if all the combustible ice was lying under the seabed, waiting for us to detonate it, we wouldn't be able to detonate it?"

"Do you know what a huge amount of exudate from the bottom of the sea, that is, reactants with combustible ice?"

"Do you know how strong the technological development and how strong the civilization is needed to ensure that all the reactions explode at the same time?"

In the quiet combat command room, Duan Qing's questions were thrown one after another.

Although the volume was not loud, it aroused a great shock on everyone's mental level.

Xu Liang had already guessed the answer she wanted to say. However, the middle and high-level officers next to them who reacted slowly and half a beat did not feel cold until these questions were asked!

The hint couldn't be more obvious.

If all the data of Duanqing is true, then there is only one answer to the question of "who lit the fire"!

"It's another civilization!"

"A civilization much more powerful than us!"

"This civilization has been hidden at the bottom of the sea for a long time, and it is 'them', and it can only be the fire lit by 'them'!"

"And the 13-level tsunami is only the first step in destroying us!" Duan Qing said in a deep voice.

At this time, the combat command room was so quiet that even a needle could be heard clearly when it landed.
