"The willow tree is above the seaman?" When Liu Chang heard Li Qingshui's words, he was a little puzzled, "The people under the sea have giant beasts, American technology, and all of them are brain domain mutants. Of the two, I think the undersea people should be more dominant. Moreover, because of the support of the behemoth, the undersea people can completely turn a nuclear bomb without a guidance system into a single weapon, and they can carry out a nuclear strike purely by inertial impact. ”

Liu Chang himself had launched a nuclear bomb attack with a hand cannon - so he believed that the behemoths possessed by the undersea people, who were hundreds of times larger than him, were more capable of firing nuclear bombs alone.

Nuclear bombs are all ready-made, and it is not difficult for Haitians to modify a launcher - and Willow was afraid of even humans who did not have nuclear launch capabilities on the human side, so it should be even more afraid of the weapons possessed by the people under the sea.

"You think Willow is afraid of nuclear weapons?" Li Qingshui said about Willow's problem, the happy component in his tone was sharply reduced by half, and his tone brought out a deep sadness, "Willow has always been afraid of nuclear weapons not for the nuclear weapons themselves, but for the nuclear winter." ”

"Nuclear winter?" Liu Chang frowned, trying to recall whether he had any knowledge reserves in his mind, but after thinking about it for a long time, he didn't come up with a reason - although he is now a brain domain mutation, but because the time of the mutation has only been a few days, and in the past few days, he has been busy non-stop, and he has no time to calm down and systematically study knowledge.

And knowledge is such a thing, it's not because your IQ suddenly becomes high, he can jump out of thin air. The flexibility of the brain will make it easier for people to learn knowledge, and it is not easy to forget after learning, and they can apply what they have learned. But Liu Chang has never studied at all, so naturally he is lacking in knowledge.

"Hmm. Nuclear winter. It seems to know Liu Chang's predicament. Li Qingshui explained in a calm tone, as he did a few years ago: "Nuclear winter is after the nuclear explosion. The environmental phenomenon caused by the dust flying into the stratosphere of the atmosphere, because after the nuclear explosion, the particles of the dust are very small, so they can be above the stratosphere. Stays can be up to a year. ”

"And because the dust blocks the light, there is a greenhouse effect on the ground, which causes the surface temperature to plummet. You know what that means, right? ”

"The temperature drops again?" When Liu Chang heard this word, he instantly understood the serious consequences that this matter might cause.

The temperature on the surface of the earth is now very low, very low -- much lower than the temperature of the Earth's ice age. This temperature of dozens of degrees below zero has made the earth's organisms and the ecosystem face a great challenge, if the temperature drops again because of the nuclear winter. Then all the life systems on earth will collapse.

"If nuclear winter comes, how much will the surface temperature drop?" Liu Chang asked.

"If only time is enough. It is possible to reach infinitely close to absolute zero. Li Qingshui said: "After all, there is such a thing as heat. It was brought by the sun's rays, originally because of the coming of winter. The red mist has blocked a large part of the light, and if it is covered with a layer of dust, the double layer of heat filtering, the equation that blocks the light is not additive, but multiplied or powered. Li Qingshui explained: "At that time, the ground may fall into absolute darkness, and if the heat consumes the writing, it will be very close to the temperature of those lightless stars outside the universe." ”

"Oh, no wonder, after the night came, the big willow tree turned out to be much more honest." Liu Chang sighed, "How many nuclear weapons do you need to cause a nuclear winter?" ”

"In the past, the figure given by the United Nations was 5 billion tons of equivalent, but now, it should be less than 1.5 billion tons, because of the balance of red fog on the environment, so the environment has less tolerance for heat loss, which is the real prophet of the future!" As Li Qingshui spoke, his eyes looked at the sky and became hollow.

And Liu Chang calculated the number of 1.5 billion tons of equivalent and found that this number would not kill a large willow tree buried 800 feet on the ground. After all, the willow tree has an area almost equivalent to three provinces, and the roots are even deeper into the ground, so it is not so easy to kill them all.

But the people at the bottom of the sea are not stupid, and if they come this time, if they are not a little sure, they will not come to die.

So, the problem becomes complicated -- the two sides are at war, there are the constraints of the balance of the environment, there are humans sitting next to the fisherman, and there are all kinds of brainless animals to make the variables.

Therefore, this is a battle in which Liu Chang cannot deduce the course of the battle -- or war, no matter how much he spends his brains. After all, both sides of the battle are the current true throne-level overlord species on the earth, and both have intelligence beyond humans and the ability to survive above other species.

And Liu Chang has a benefit, he won't think hard about things he can't figure out.

After retreating from the difficulties, he knew that at present, the most important thing for him was to recover his body first, and then make other plans.

……

Time waits for no one.

During the confidential talks between Liu Chang and Li Qingshui, the progress of the undersea people will not be slowed down in the slightest because of the aborted death of Willow Shu's plan in Beijing.

On the nearly 1,000-kilometer journey from Qingdao to Zhengzhou, the seabed people and those giant beasts, like an expeditionary force, are constantly stepping on their footprints.

During this journey of more than 1,000 kilometers, the coverage of the jungle is very high, but the tall trees and dense shrubs cannot stop those monsters whose size reaches tens of meters or even hundreds of meters in length. These monsters, wearing armor and holding battleship-level "guns" in their hands, carried teams of undersea people on their backs, opened up huge passages in the frozen jungle - no matter how difficult the terrain was, it could not stop the progress of a huge intelligent creature.

Wherever they passed, the mountains and rivers shook, and the great trees collapsed.

Maybe the jungle can stop the tires of human vehicles, maybe the mountain streams can stop the tracks of tanks, but it definitely can't stop these giant beasts from moving forward. They are very intelligent and agile, and there are all kinds of seabirds and even helicopters in the sky - except that helicopters are obviously a modified species, and the pilots of the planes are no longer humans.

The little sea creatures with bulging eyes, each of them seemed to have very strong eyesight, piloting helicopters, they were no slower than the giant seabirds in the sky, and they were in the sky, scouting the way for the expeditionary force below.
