Lin Sen, who rushed out of the underground passage, would never have thought that what greeted him in the room at this moment was actually a group of infected xenos who had been silent for fifteen years.

Although these things are stiff when awakened, the bloodthirsty instinct is still crazy.

As each of the surviving cells on their bodies felt the energy available for devouring and ingesting, they began to squeeze themselves frantically, and then rushed towards their target.

It's a pity that these things have been silent for too long, no matter how crazy they are, they now look like old men in their last years, and all their actions are like slow motion.

Lin Sen was a little scared at first, but when he saw this scene, he wanted to laugh inexplicably, but it was a bit out of place, so Lin Sen didn't say a word, took down the "growler" behind him, and went all the way forward, beating these things into ashes one by one.

The surging energy solved these vulnerable xenomorphs in three or two clicks, but Wu Huan scolded again and again: "Stupid! A sucker! What are you shooting! Just get around and go! You know how much trouble you're going to get with those shots! ”

Lin Sen also had a hot brain, and now that he thinks about it, he can't help but regret it, but Lin Sen's style of doing things does not say that he regrets it, since he has done it, he is ready to bear the consequences.

So Lin Sen didn't answer, put away his weapon and continued to rush towards the right fortress.

When he arrived at the computer room, sure enough, the piled up corpses were also restless, Lin Sen felt like a magnet, and those xenos saw Lin Sen passing by, and they stretched out their hands to him like beggars, but unfortunately they couldn't catch it at all.

Lin Sen, who fled back to the fortress on the right, learned to be obedient this time, and when he entered the house and saw that the female corpse in the office area had also crawled up, kicked her down with a flying kick, and then pressed her under the table with a single kick.

Then I listened to Wu Huan and said: "Take out all the things and arrange the defense according to what I said." ”

Lin Sen nodded silently and began to get busy, and Wu Huan didn't have time to explain the use of equipment to Lin Sen one by one, only told him how to install it and where to put it.

About half an hour later, as the night deepened, Lin Sen finished placing the last defensive mine and retreated to the office on the inside of the fortress, holding the Growler with a nervous expression.

At this moment, only the sound of Lin Sen's breathing and the fading struggle of the skeleton outside the room were left, and everything was quiet.

This kind of silence is not normal.

Originally, Lin Sen could faintly hear the sounds of insects in the woods and the sounds of some unknown birds, but now the world outside was completely quiet, and even the sound of the wind was gone.

It's so weird, it's so abnormal.

While Lin Sen was highly nervous, he was also communicating with Wu Huan in his heart.

"What the hell is going on, can you say it now?" Lin Sen asked.

"I just hope I'm wrong, but if it's true, it's too much trouble!"

"Don't beat around the bush." Lin Sen rolled his eyes angrily.

"Huh...... Let me start by asking, how much do you know about xenomorphs? "Wu Huan has a temper.

"Not much, only that they can infect humans, and they are bloodthirsty!" Lin Sen had only these xenos in his impression, although he had heard of some special xenos, such as the mother of the infected, a disgusting monster covered in sucker-like sores like a huge pustule, but he had never actually seen them.

Even the xenos that caused him to fall into the pit that time were no different from the xenos who bit off the spine of Lin Sen's sister Lin Yan.

"Your common sense is pretty good." Misty Huan's little problem of teasing people was always there, and she paused for a moment and said, "Those are just the lowest xenomorphs, and they can't even be considered xenomorphs, they are just infected. There are many types of real xenomorphs, generally speaking, there are second-class, low-level Z-level, medium-S-class, high-level K-class, nightmare level and dominant-level, their degree of evolution is far beyond your understanding, even in the face of human cutting-edge weapons, these xenos that seem to only have the most primitive killing ability can easily hunt humans. ”

Wu Huan's lecture, Lin Sen listened very carefully, but he was also a good student who was eager to learn and loved to ask questions, when he heard the word "hunting", Lin Sen couldn't help frowning and asked, "Why do they hunt humans?" Is it true that all species other than humans have enmity with humans? ”

"Yo, your question is quite mean, I really didn't think to say it without asking. In fact, it is not just the hunting of humans, for xenomorphs, any target with evolutionary value is prey, and there is no difference between the same and the other. However, we later discovered that the reason why xenomorphs are more inclined to hunt humans is that humans are relatively weak, and partly because the progenitor cell base fluid of humans is rich in the inhibitors they need, although this component has not been fully resolved, it is certain that the cell base fluid in the human body is like a drug to xenomorphs, which can give them a sense of calm and pleasure in the crazy evolution. Wu Huan explained in detail.

Lin Sen listened very carefully.

When he heard that humans were like drugs to xenomorphs, Lin Sen finally understood why those alienated monsters were so crazy about wanting to kill. If people can't suppress their cravings for drugs, they are probably not much different from those aliens.

But Teacher Wu Huan seemed to be off topic after talking for a long time.

Lin Sen couldn't help but remind: "So, you still haven't said what makes you so scared!" ”

Wu Huan was silent for a while before saying: "If my guess is correct, we experienced a 'death notice' in the arsenal just now, and it is by no means a coincidence, it is a real evolutionary ability, although it is not clear why it affects us, but I can be sure that there is an Xenomorph above the S level near this outpost." ”

"What!?" Lin Sen was a little incredulous.

Is there such a bug-like existence in the evolutionary ability? It sounds like a dream.

"There is no doubt that I was seriously injured when you first met me, and that time it was because my team was chased by a xenomorph who had evolved the ability of 'Death Prophecy', and I was the only survivor, but I was also bitten off my spine by that monster and sucked the cell base fluid, and the feeling of being eaten raw was really ...... Quite interesting......! Wu Huan said lightly, but Lin Sen was already in a cold sweat.

He suddenly realized that he had always despised the little girl in his body, or in fact, he was the silly boy who had just entered the school, and he still felt good about himself......

"Now, do you know what I'm afraid of? Hehe......" Wu Huan's mood began to fall, and the feeling of indifference was like losing hope.

Lin Sen was silent for a long time before he said, "Didn't you say that you would accompany me back to Cerberus?" Gave up so quickly? ”

There was a slight tremor in the comfort of pretending to be calm, and although he failed to pretend to be cool, he also made the fog laugh.

"yes, I think I did!"

"Heh, you have to talk and count." Lin Sen also relaxed a little, he quietly raised his head and looked out the window, but the moment he poked his head out, a silver mark flashed.

The fighting instinct in Lin Sen's body allowed him to quickly dodge the fatal blow backwards, and when he looked at it again, the growler in Lin Sen's hand had already turned into two, and at the same time, there was a sharp roar from the defense device outside the house, and the mine was triggered.
