No kind of language and behavior can eliminate such hatred, so for so many years, the Martians have sharpened their knives and horses, waiting for the earthlings to come back to retaliate, and there are thousands of particle cannons flying around Mars, but they have not waited for 200 years - it is generally believed that the earthlings have become homeless people, and they don't know where they have gone, but everyone knows that they must still be alive in some places, eyeing Mars - there is no place in the solar system other than the earth that can make people live more comfortably than Mars.

So it's not afraid that the earthlings are coming, anyway, Martian physics is fifty years ahead of the earth, and all your physical attacks are ineffective against the Martians, so I'm afraid that they won't come, hiding in the corner and suffocating.

In the middle of the landing craft rushing into the Pacific Ocean, Zhang Tianhe had been thinking about the question of thermonuclear war and Martian war, and he was a little distracted, and now he called up the hologram of the landing craft's detection while giving a few orders, asking Shulmi to warm up the huge particle cannon on the Star and keep an eye on Shi Kning's vicinity to prevent any accidents from happening.

The largest particle cannon on the Star can directly penetrate the Earth after gathering energy, but concentrating the energy in such a narrow range will not do anything to hit the Earth at this magnitude, just like embroidering needles to prick the blue whale (alas, this great creature is extinct on Earth), it doesn't feel any difference. But you can feel the power of this cannon, if other ships approach the Star, he hits this cannon on someone else's engine, penetrating its magnetic field, the fusion engine will explode out of control, the Martians used this craft to defeat the earthlings in the first place, but now it is just closer.

Back to Earth.

Now the entire land of the earth is emitting green light at the junction of the plates, and the original thermonuclear war provoked the fission of a large number of heavy elements on the earth, and no part of the earth's crust is clean, but the thermal radiation is more obvious in these places where the plate movement is more active, and it looks very terrifying from space. But the earth is not as dead and silent as the moon, her planet has its own unique circulatory system, and now the nuclear clouds that permeate the surface of the earth have been metabolized, if the earth can also breathe, then she is equivalent to a few puffs of smoke, but the problem is not big, with her magnitude this cigarette will not affect health, but this smoke into the earth's body makes human beings unable to survive. People need air, water, and the sun (or the moon as well) to live, and thermonuclear warfare destroyed all three, but the sun was the first to recover, and the earth metabolized all the nuclear dust in the air to the land and the sea decades ago, so now it can be seen directly from space.

Actually, she is not much different from before, the green is a little green, but just like the girls change their makeup, changing their clothes may be refreshing! You know, there was a time when her main trait was red, when she was just starting to develop, she was a fiery metallic planet, and her beauty was perhaps more intoxicating at that time, but it was probably not a good thing for humans.

Therefore, although the earth is no longer suitable for human habitation, she is still extremely beautiful, and it may be a lot easier for her after the human beings leave. Nowadays, the sky of the earth is still blue, the ocean is a little green but it is still blue, and the land is grayish and yellowish and green, but from the aesthetic point of view of art, this contrast makes her bluer, so the earth is more beautiful in color. There was a painter in Italy named Caravaggio in the Earth Age, and his oil paintings were particularly fond of using light and shadow effects, and if he were asked to paint an earth, it might be like this.

In the life of the earth, there have been countless earthquakes, global volcanic eruptions, comet impacts, asteroid rain impacts, magnetic pole displacements, polar reversals, solar energetic particle storms, cosmic gamma-ray bursts, and even planetary cores as large as Mars collide head-on with her, for her, this is enough to be unlucky, human beings put tens of thousands of fusion bombs may be equivalent to a girl mite disease, When the earth was flying with the sun, she suddenly itched a little, scratched her face and set off, which caused skin cystitis and her skin was bad for a while—that's all, but she couldn't live if she scratched it like this, so she had to change places and pit other planets. As far as the earth is concerned, it makes no difference whether it is paramecium, trilobites, nautilus, dinosaurs or humans who live on her, if she can speak, she must have this sentence to give to humans: Give you a chance, you don't fight!

The Martian was not convinced, and said that sooner or later I would try again and find this field!

Ah, now the advance troops have arrived.

In the middle of the landing craft hitting the earth's atmosphere and ocean, Zhou Limin has been doing exploration, it has been proved that the amount of radiation in the air and water is not suitable for human survival, human beings can not breathe such air and drink such water, people can travel on the earth for a short time, but it is impossible to live here for a long time, the human body is actually very fragile, human life is a process of continuous aging and disease, in this environment, people will not last long, will swallow quickly, this discovery makes everyone a little depressed. In fact, everyone has this expectation, but seeing and thinking are two different things after all, because the observation angle is different, for a while no one on the landing craft speaks, everyone just looks at their respective instruments, and dives down from the landing craft.

The Martians' monitoring of the Earth is like this, they are concerned about whether the planet is not suitable for a large number of human gatherings, whether there are signs of a large number of large-scale industries created by human beings, and occasionally explorers will come to take a look, but in recent years, as the Martian civilization has become more and more stable, this kind of exploration is almost non-necessary to see her, because she knows that she will not be able to let humans survive for at least a few hundred years, and there seems to be nothing wrong with living on Mars. But this is the core problem: according to George, the Martian Council actually anticipates the negative impact of life on Mars on human beings, but the vast majority of people do not have this sense of crisis, after all, people will not live for more than a hundred years, and it is not their turn to worry about this. For the Martian government, its doubts about the Earth mainly come from whether its earthlings will come back, and the secondary is to observe her recovery, after all, the evil consequences of life on Mars have not yet been shown, so its monitoring of the Earth is to beware of the earthlings. The council knows that the earth is getting better day by day, but it is still far from the return of humans, so they mainly observe industrial signs, not environmental changes.

The landing craft has different observations than the Martian government, Zhang Tianhe has other plans, Jenny Yang also has other methods, and Zhou Limin and George's student Brian also has other observation methods, but no one can be happy after they really come back, because this place is what they know, and it doesn't seem to have changed.

The Earth is now better known as the water balloon, and the thermonuclear war has triggered a series of chain effects, the most obvious of which is global warming, the melting of glaciers at the poles, and now you don't see the Arctic Ocean on Earth, only the North Water Ocean. There is still some ice left in Antarctica, and now the coolest and most temperature-friendly place on Earth is Antarctica, whose ice has not yet completely melted. From the perspective of space, the rise in the sea level of the earth has flooded a large piece of land, but it is still the previous sentence, it is not a big problem for her, she has lived days without water and days when there is more water than now, it is not a big deal, and as long as she maintains the current metabolic rate, the temperature will still slowly decrease, but the high temperature and low temperature do not matter to her, or can only hurt human beings themselves.

The landing craft set the line straight down, and at this time George also came to the captain's room, and was directing Brian to scan the surrounding biological environment, at first more than 2,000 meters deep, he found nothing, and the ocean was dead silent.

"Well, as I thought, the creatures in the shallow sea were destroyed by that war...... "George said as he looked at the scanner from the hologram, "and we should take some samples of seawater and see how the microbes are doing." Brian! Did you hear me? ”

"Just do it a little bit further......," his student replied.

"I don't know if I can see fish, or shellfish, or crustaceans, cephalopods, and so on...... A war would turn the evolutionary history of living things back hundreds of millions of years, and who would have predicted that......" George said.

"I think those people who fired the first shot in a nuclear war would have expected ......," Zhang Tianhe replied, "We humans are the only animals that if I have to die, I'd better drag others to carry them on our backs." ”

"From the point of view of biological evolution, it may not be a good idea to go ashore, after all, seawater metabolizes pollutants much faster than land and air......

"Actually, it's pretty much the same, no one is good when the war reaches the atomic level."

"But the radiation in the ocean is much smaller than on land, and the medium is different......"

"Four thousand meters, is there nothing?" Zhang Tianhe asked.

"The scanner didn't find anything...... In fact, this may also be because this place is where the tectonic plates meet, which is not usually seen, but now this is the place where the radiation is most severe......"

"Didn't you say that the further you dive, the less radiation you have?"

"That's right! But the living conditions of creatures diving into this depth are getting worse and worse! ”

"Don't talk like that, that's what humans think is the living conditions of creatures......"

The landing craft in the middle of Zhang Tianhe's conversation with George dived to a depth of more than 5,000 meters, and the radar of the landing craft was divided into several parts, mainly the optoelectronic radar, which emitted light waves and electromagnetic waves outward, and used the reflected photoelectric waves to scan and detect. Zhou Limin has a radiation measuring instrument, Brian is measuring bioelectricity, and Jenny Young can sense a magnetic field, and nothing near the landing craft can escape everyone's eyes under such a comprehensive detection. But that's it, from Shi Kening to Zhang Tianhe, they first heard a strange sound, the landing craft creaked as if it had suddenly been strangled by something, and then there was a rattle as if something sharp was vigorously crossing the outside of the landing craft.

"Sonic cannon!" Zhang Tianhe pushed George away and shouted.
