It was a cold night, and it was pitch black all around.

Well, it's not that dark in fact, the embers of the explosion in the central control room are still there, and through the remaining sparks, you can barely see the surroundings.

In fact, these Mars are so sparse that they would not be able to be seen at all if it were a normal night. But now the surroundings are so dark, like an airtight dark room, so you can barely see something through Mars.

For example, the thick tree behind them, or the crushed passage not far away. According to Duanqing, following this road, it only takes 250 meters to reach the side of the ship, which is very close.

However, absolute darkness blocked them, like the dark maws of a prehistoric monster, not knowing what was in the darkness. Although only 250 meters.

Xu Liang even doubted whether the night itself was the real night.

Because no matter how dark it is, you can at least see some stars, or something in the sky, but now you can't see anything.

"It's not night according to the time." Duan Qing analyzed, "How long has it been since the end of the tsunami, in fact, we can't be completely sure. Duan Qing said, "When I woke up from a coma, it may have been a few hours, but it may have been more than ten hours, this, cough, from the fact that I haven't eaten a bucket of instant noodles yet, it can be seen that the time should have passed a long time." Then, in terms of time, it should be a daylight day. This level of darkness is too abnormal. ”

From where they were, they could see the sky, because the roof of the biosphere, the deck of the Ecosphere, was glass.

It is precisely because of this that several people feel that the current "black" is not normal.

"Two possibilities." Duan Qing said, "The first one is that the Ecology has sunk to the bottom of the ocean. This is the most likely. ”

"Because no matter how clear the water is, its light transmittance is only 200 meters, and no matter how deep it is, it is absolutely a pure black world. The 'Ecology' I designed has undergone a special structure to resist the ultra-high pressure of the deep sea, so we can explain the current darkness at the bottom of the deep sea. ”

"The second possibility: we're still on the water, the tsunami is gone, and there's an amazing change around the world, and it's so amazing that we can't see the sun at all!"

Xu Liang thought for a moment.

"Amazing change? What are you referring to? ”

Duan Qing: "In the process of building a large ship for a long time, we have actually thought about many other questions, such as what kind of changes will occur to the surface environment after the 13 tsunami? This change is an astonishing change. ”

"For example, we speculate that the surface environment after the tsunami is: global warming! Eventually, the Earth becomes like the surface of Venus, producing an extreme greenhouse effect, and the world is dead silent, with no life alive. ”

Xu Liang: "Jin Xing (not Sister Jin)??" Can you elaborate on that? ”

"Hmm. In fact, the greenhouse effect is already a fairly popular concept. Carbon dioxide, a greenhouse gas, is the main culprit, which is why carbon emissions are being limited globally. But few people know that carbon dioxide is not the only greenhouse gas. ”

"In fact, methane is also a greenhouse gas."

"And, relative to carbon dioxide, methane is an extremely strong greenhouse gas! The same amount of methane produces more than twenty times the greenhouse effect of carbon dioxide! However, because the amount of methane naturally present in the atmosphere is very small, the greenhouse effect caused by methane is not obvious. ”

"yes, you've probably guessed what I'm going to say."

"After the tsunami, this will change completely! This is what I and other scientists have speculated is the most likely scenario for the global aftermath of the tsunami. ”

"This tsunami is a total explosion of all methane on the ocean floor! This explosion is enormous, and there will always be incomplete combustion of methane released into the air, and only a small part of the total amount will not be completely burned and enter the air, which will increase the greenhouse effect of the atmosphere to a maximum! And even more deadly, the methane explosion itself produces a lot of carbon dioxide......"

"So if you combine the two factors, global warming is almost inevitable!"

Xu Liang dragged his chin and thought for a while, and seemed to have some truth: "What is the situation of Venus you just said?" ”

"Venus is a 'model planet' where the greenhouse effect has developed to the extreme. As a planet in our solar system that is quite similar to ours, it has an atmosphere that contains 1,500 times more carbon dioxide than our Earth, and its surface temperature reaches ...... 500 degrees Celsius! Venus does not have any liquid water on its surface, and in addition to carbon dioxide, there are dark clouds and torrential rain formed by concentrated sulfuric acid in the atmosphere, making it a hellish fiery red world, and its 'golden' appearance also comes from this. ”

"We're going to be the second Venus, and that's what we speculate will be Earth after the magnitude 13 tsunami."

If that's the case, it's pessimistic.

"Of course, this is without manual intervention by the undersea civilizations that have not yet appeared."

"But this is a global change, and even undersea civilizations will not be able to reverse this form in the short term."

"In fact, even the waste heat from the explosion of all methane compounds can raise the surface temperature by a lot."

Duan Qing said quite a bit about the reasons why the world is going to warm, and it does have some truth.

It seems that global warming is inevitable.

However, Duan Han, who was studying rabbit fangs, suddenly raised his head and interjected, "It's so cold." ”

Duan Han hugged his arms and added a piece of clothing from Lao Xu's bag, but he still felt cold, and it was getting colder and colder.

Sister Duanqing was also a little shivering, and she had already felt cold. So he frowned and said, "I can't figure this out either, so, what's going on outside?" Must check it out as soon as possible. Who's that, Xu Liang, right? We thought we shouldn't rest for the night, and now we should go straight to the road. ”

"It's a short distance, only 250 meters!"

"Follow the direction of the crushed passage to get out!"

"Moreover, if it is not seawater outside, you can use your fangs to corrode a hole in the glass outside, and you may go to the outside nature. You'll know what's going on outside! ”

Duan Qing's words were very eager, but she found that Xu Liang didn't listen very carefully.

By the light of the embers of the explosion in the central control room, she saw Xu Liang tilting his head and ears sideways to listen to something else...... Ignore her!

"Are you listening to me?" Duanqing was a little anxious. Of the three, she was the one who wanted to know most about what was going on outside.

"Listening." Xu Liang replied briefly.

"Then you don't ...... yet"

"Shhhh......h Sister Duan Han pulled her sister next to her and explained in a low voice: "Lao Xu's hearing is much more sensitive than ours, don't make a sound first, he may have found something." ”

Xu Liang did find something, he even lay on the ground, his ears on the ground. This can be felt more precisely, and his expression is becoming more and more serious.

Duanqing still couldn't hear anything, but she suddenly thought of something related to it:

Mutant creatures!

Those rabbits can mutate, why can't other creatures? The rabbit has retreated for the time being, but other creatures may not come?

Could it be ......

At that moment, a voice began to hear in her ears.

From nothing, from extremely subtle to progressively clear.

"Rustling ......"

"Rustling ......"

It's a bit like the sound of shaking paper, and it's also a bit like the sound of branches and leaves shaking.

Just when Duanqing wanted to listen more carefully to what it was, Xu Liang suddenly slapped his thigh and jumped up!

Immediately after, he began to rummage through things in his backpack like crazy!

Even in the face of the rabbit just now, Duanqing didn't notice that he was so nervous!

"What's wrong? What are you looking for? ”

"Fire! Hurry up and start a fire! Xu Liang threw the contents of the backpack out one by one, and finally found the flint, "Hurry up!" Otherwise it will be too late!! ”
