Most importantly, if it makes sense to use one Scavenger spacecraft for reconnaissance, it is a bit unreasonable to use three Scavenger spacecraft at once.

"Brother Fei, what do you say?" Xiao Qiao asked Liu Fei.

"I don't know." Liu Fei stood up and beckoned to Liu Xiaofei, who hurriedly got up and followed.

"Brother Fei, what are you going to do-hey, go to fitness-" Xiao Qiao watched Liu Fei enter the gym a little depressed.

"Sleep for a while, the romance begins." Da Qiao sighed, she was deeply dissatisfied with Xiao Qiao's stubbornness and sticking to Liu Fei's side despite a girl's family.

"Oh-"

Looking at Da Qiao's angry look, Xiao Qiao spit out his pink tongue, and reluctantly stood up and followed Da Qiao into the bedroom.

――

"What would you do if you did become human?" Liu Fei did not exercise, but walked to the floor-to-ceiling window and looked at the deep night sky.

"I don't know." Liu Xiaofei thought for a long time, and his face showed a trace of confusion, obviously, he hadn't thought about this problem. Evolution is just an instinct of aliens, just like humans eat and dress in pursuit of a better life.

"Aren't you aliens going to die?"

"Theoretically, not, however, the vast majority of xenomorphs will die." Liu Xiaofei answered the alien questions quickly and without thinking.

"Why?"

"Aliens will degenerate if they don't evolve, and degradation is death, the vast majority of newborn aliens can't evolve to a higher stage, they will age over time until they die, and if they want to live, they must evolve through constant migration."

"Why keep on the move?"

"Only constant migration, hunting for higher intelligent beings through migration, can make up for genetic defects."

"If the intelligence of the aliens surpasses that of humans, then don't you also have to die?"

"I don't know, theoretically, in the universe, there are many planets occupied by us, but in fact, after we hunt down the advanced creatures of that planet, if we don't have the ability to migrate away from that planet, we will gradually die."

"In other words, every time you occupy a planet, that planet will gradually become barren and devoid of any advanced life?" Inexplicably, Liu Fei felt a little uneasy, the evolution form of the alien must allow them to keep invading and plundering, which coincided with the evolution form that the little monk said.

"Yes, at the moment, the only planet that can allow us to thrive on a large scale is the one inhabited by humans."

Liu Fei didn't speak, and there was a long silence.

It is inferred from the evolution of the alien that as long as the intelligence of the alien does not surpass that of humans, then the alien will not die.

What would it mean if the intelligence of the aliens surpassed that of humans?

It means that human beings have been wiped out by the aliens, and the aliens will continue to expand in the universe, looking for higher levels of life as opponents, and then conquering each other, and this evolutionary form will always be replicated.

If the alien has been invincible and cannot meet a more powerful existence than it, then the alien occupies the entire universe, and the life of the alien has come to an end.

This is a desperate evolutionary history - it is impossible for two advanced intelligent beings to exist in the universe at the same time.

Without the enemy, that is, at the end of life.

Obviously, the evolution of humans is somewhat different from that of aliens, at least, humans don't need enemies to reproduce. The evolutionary form of human beings made Liu Fei unable to agree with the theory of cosmic destruction that the little monk said, after all, if only human beings were left in the entire universe, there was no reason for human beings to disappear.

The problem is that human beings are certainly not the most powerful beings in the universe, and there are countless powerful life forms in that vast universe.

――

"Come, don't you want to learn human fighting?" Liu Fei is not a person who drills the horns of the bull, so he doesn't bother to think about it if he can't figure it out, so he pulls out Yuehua.

"Okay—"

Liu Xiaofei suddenly jumped up, with his simple head, he naturally didn't think that Liu Fei wanted to take the opportunity to kill him, let alone that Liu Fei's use of a knife was unfair and dangerous.

"Whoosh"

In a swift sound of breaking the air, Yuehua rushed like a bolt of lightning, with a momentum like a rainbow and a murderous aura.

"Whew-"

Liu Fei's hand speed was too fast, and he struck first to take the lead, and when he was caught off guard, Liu Xiaofei couldn't dodge, and was cut on his right arm by Yuehua, and immediately, the muscles of Liu Xiaofei's arm turned out, revealing the dark muscles inside.

Liu Xiaofei let out a thrilling chirp, and retreated one after another, and in that retreat, the valgus muscles recovered at a speed that could be seen by the naked eye, and it looked extremely weird-

Liu Fei didn't stop, Yuehua flashed rapidly in the air, and the sword light was like the endless river, rolling towards the colorful alien shape, the speed was so fast that it was shocking.

It's still a bit of a learning experience, it's a desperate fight, and the gym only sees countless afterimages moving rapidly, like ghosts.

In just a few minutes, Liu Xiaofei had already been stabbed hundreds of times, and he was scarred and shocked.

Liu Xiaofei didn't think that this was an unfair battle, it was completely possible to describe his fighting spirit with high spirit, in the impenetrable sword light, he hadn't forgotten to observe Liu Fei's every move, in this kind of contact, he would keep imitating Liu Fei's movement and change direction.

As time went by, Liu Fei became more and more shocked, Liu Xiaofei's progress was very fast, at the beginning, he couldn't dodge Yuehua's edge at all, and later, Liu Fei's chances of hitting him became smaller and smaller.

Liu Xiaofei's bouncing ability and physical toughness are extremely amazing, and his judgment ability is extremely sharp, in the gradual adaptation, he has been able to find Liu Fei's law, Liu Fei must keep changing the angle, not to let his knife technique repeat, so as not to let him predict Yuehua's next trajectory.

This is an extremely challenging battle for Liu Fei.

Human limbs are fixed, can not change direction like aliens, in fact, every movement of human beings is traceable, if the body as the axis, the diameter of human hands is not more than two meters, in this less than two meters to make others unable to predict the next trajectory, it can be seen how difficult it is.

It's easy to kill the multicolored aliens, dismembering them into thousands of pieces in an instant.

Gradually, Liu Fei gave up the idea of killing Liu Xiaofei.

In fact, no matter how fast Liu Fei had, obviously, it would be impossible to dismember Liu Xiaofei into thousands of pieces in the midst of lightning and fire.

At present, Liu Fei's highest speed record is 30 knives per second, and this is Liu Fei's highest record.

Theoretically, if the strength and speed are enough, thirty knives are enough to dismember an alien, but there is often a big gap between theory and reality.

In addition to its super speed, the multicolored alien itself has a terrifying ability to resist blows, even if Liu Fei's thirty knives completely slash into the colorful alien, the degree of cutting is no longer fatal. What's more, the multicolored alien also has the ability to heal beyond the reach of humans, if the wound is not deep, it can recover almost immediately, from the first knife to the thirtieth knife, perhaps, twenty of them have recovered.

The Alien's body structure is comparable to that of a chemical factory, and it is too perfect.

Giving up doesn't mean the end of the fight, Liu Fei's willpower is unusually tenacious, and he begins to test the specific location of the multicolored alien linear heart through skill.

Speed was no longer able to kill the alien, Liu Fei began to pay attention to skills, and only skills could test the linear heart of the colorful alien.

Liu Fei firmly believed that if he could grasp the exact location of the linear heart of the multicolored alien, with his knife speed, he could completely smash the linear heart of the colorful alien in a few seconds.
