Although he was very interested in the history of Mars, in the next few days, Chen Mulin did not bother the mother and son, but went to do the experiment of barrier defense against shock waves.

Facts have proved that Xuannu's idea is feasible.

After several days of repeated experiments, the commissioning was finally completed, and the barrier had the ability to defend against shock waves, and at the same time the flight was guaranteed.

For example, in the event of a sudden shutdown of power at high altitude, the barrier can also counteract the impact force of the fall.

After Chen Mulin finished his work, Tie Zhenzhen's mood also stabilized a little, and he couldn't see any sad emotions from his expression.

Taking advantage of the lunch time, Chen Mulin and Tie Zhenzhen talked.

After thinking about it for a long time, Chen Mulin didn't know how to speak, after all, there were too many questions on Mars, and he couldn't finish asking them one by one, so he had to pick the key points and ask the whole Martian question directly: "Sister Zhen, there is one thing I'm curious about, what happened on this planet?"

The title of Sister Zhen was called out by Chen Mulin on his own initiative, and he couldn't keep calling Ms. Lady, and it was not good to call her by name, after learning that Tie Zhenzhen was only in her thirties, she finalized the title of Sister Zhen, and naturally, Chen Mulin became Xiao Chen.

When Tie Zhenzhen heard Chen Mulin's question, she was stunned for a while, and was silent for a while, as if she was thinking about what she had written, and then she spoke: "Actually, I don't know these things very well, but I saw a little bit when I was in school before." ”

Chen Mulin was not surprised when he thought about it, after all, it was a long time ago, and it was normal for Tie Zhenzhen not to know.

Although there is only a little information, it is better than nothing, and Chen Mulin became serious.

"It's better to know a little than nothing, let's hear it!"

"Okay then!" Tie Zhenzhen nodded, and said after brushing his thoughts: "Actually, all this is caused by aliens, because their jaws are very pointy and their heads are like a triangle, so we call them triangular people......"

At lunchtime, Tie Zhenzhen told everything she knew, although there was not a lot of information, but for Chen Mulin, who had watched a lot of science fiction movies, it was not a thing, and his brain could be completed.

It turned out that after the Triangle Man invaded Mars, due to the serious damage to the spacecraft equipment and other equipment, the invasion was not successful, although the Martians suffered heavy casualties, but they still almost wiped out the Triangle Man.

And the leader of the triangular people is naturally annoyed and angry, his equipment is so good, why should he be exterminated by you Martians, how humiliating it is, in order to save face, the leader of the triangular people decided to die with the Martians, and moved out an artifact, which shook the buildings on the surface of the entire planet into powder, including the black technology artifact, which is also the reason for the thinning of the Martian atmosphere.

The Martians had long known the intentions of the Triangles, but they had no choice but to hide under the dangerous underground.

And those alien beasts existed a long time ago, they rarely go out of the ground, almost all hide underground, and only a few times will come out, that is, the Martians hid in the territory of the alien beasts, which saved their lives.

This is not over, although the leader of the triangle people made the decision to die together, he still does not want to die, and when he activated the artifact, he led his subordinates to hide underground early, and he also survived.

Of course, at this time, both sides thought that the other was dead, and for a long time, they were developing separately, trying to build a second home underground, and they began to wage war with the alien beasts.

Relying on talents and small arms left behind, the triangular people are naturally relatively easy to deal with strange beasts, as long as they are given enough time, they will soon be able to regroup with knowledge.

But they were not so lucky, the triangular people were too careless, and their numbers plummeted under the sneak attack of a large number of strange beasts, and the most unfortunate thing was that all their talents died.

A critical attack of the alien beast has set the technology of the triangle people back by N years, and those who survived, even if they have the ability to develop technology, are all three-legged cat kung fu, they have lost a lot of advanced technology manufacturing capabilities, and they don't know how to make them, and they don't even have design drawings.

Slowly, the Triangle people also settled down, and they didn't go out of their way to provoke the beasts again.

The Martians are much luckier than the Triangle people, they know this place, and they also have a way to deal with foreign beasts, and after seeing the technology of the Triangle people, they also began to develop technology, starting from a blank slate.

But the good times didn't last long, and before the Martians studied for long, the Triangles discovered one of their living spaces, and the war was about to break out, and in the end the Martians were still defeated by the Triangles, and the space was destroyed because of the battle.

Although Chen Mulin didn't know where the address Tie Zhenzhen was talking about, it was certain that the ruins he saw underground should be the one that was abandoned at that time.

According to Tie Zhenzhen, it is recorded in their history books that the Martians once captured a triangular person, and learned from him that their group of triangular people were all defeated on the home planet, and they failed to seize power, so they had to plunder other planets.

After searching for a long time, they finally found a suitable target in a galaxy, and when they were about to get close to the target, the spacecraft malfunctioned and finally crashed on Mars, resulting in damage to a lot of equipment and equipment, and the Martians were also very tough, which led to the invasion has not been successful.

This is interesting, 100,000 years ago, the Martians had already developed a kingdom, and it was the kind that dominated the whole of Mars, and the Earth was still in the Stone Age, ready to go out of the African continent.

In other words, the combat power of Mars 100,000 years ago can throw N streets on the earth.

Note that the triangle man said that the spacecraft malfunctioned and crashed to Mars when he was about to get close to the target, and the original target was not Mars, but most likely Earth.

Just imagine, Mars is not as big as the Earth, and there is a kingdom, and the Earth is just a barren land, of course, it is the first choice for invasion, and you can catch a wild man to watch or something, and it is not too late to invade Mars after it settles down.

In this way, the earth at that time was quite lucky, if it weren't for the failure of the Triangle man's spaceship, the earth would be the planet of the triangle people.

Even if the Triangle people crashed on Earth instead of landing safely, even if their advanced technology was more seriously damaged, it was impossible for the earthlings at that time to resist the invasion of the Triangle people.

Fortunately, the triangular people crashed on Mars, if they crashed on the earth, and when they recuperate, in the end, Mars will have no ability to resist, a solar system, two planets will be pocketed by the triangular people, and Mars is still intact Mars, at that time they don't need to use the same method of dooming.

Thinking of the society of Mars 100,000 years ago, Chen Mulin suddenly became interested in the development of Mars again, and he asked: "Your history books should also record the history before the triangular people came, right? I want to compare your development trajectory with ours. ”
