The cave was dark and dark, and it wasn't a straight line, and even the headlamp couldn't shine far. But as soon as Su Lifeng glanced inside, he saw a piece of clothing that had not yet rotted. He picked at it with his bone wings, and saw a hand bone covered by his clothes.

Decay, deformed bones, and the joints are not the same as normal humans.

The one who gave up the skin bag ...... "Skin" may be one of those giant rats just now, but Su Lifeng's focus is not this. His attention was still on the cave itself.

"It's not strange that there will be xenomorphs in the tunnels, but why make holes here?" Su Lifeng thought about it, and after absorbing the E-class xenomorph in turn, he crawled into the cave.

If it weren't for the bones to open the way, he really wouldn't dare to go in so rashly.

Sure enough, he didn't climb far, Su Lifeng saw that the cave was at the end, and a huge space appeared below, and as soon as Su Lifeng got closer, he was almost smoked by a foul smell.

Fortunately, when I was doing the experiment, I smelled too much bad smell, and Su Lifeng just covered his nose, hooked the edge with his bone wings, and carefully leaned down.

This is a sewer, where the headlight line sweeps, Su Lifeng saw a large number of abandoned skins, but in the same way, in the place where people walked beside the waterway, Su Lifeng saw a lot of fresh human-shaped footprints.

"What's going on?"

A large number of xenos are transferred to other creatures to dig holes, and then more humanoid xenos are brought in here?

For what?

Judging from what Su Lifeng saw, the defense of the quarantine area was definitely very tight.

But the purpose of these xenomorphs gathering here is also self-evident......

After staying here for a long time, Su Lifeng was afraid of being discovered, after all, in the dark, he was like a huge target with a headlamp. But just as he was about to leave, he suddenly noticed something.

Su Lifeng stared at the red dot for a moment, then his bones loosened and he jumped down. He hooked the red dot with his bone wings almost the moment he hit the ground, and the next moment he was back in the cave.

"Roar!"

An indeterminate roar came from the depths of the sewers, and Su Lifeng was back inside the tunnel. The roar saw that it didn't notice anything. And it faded away.

When they were arguing about whether to go to Su Lifeng, Su Lifeng came back.

"Are you alright?" Li Heng was the first to spot Su Lifeng's figure, and as soon as he took two steps forward, he was stunned with his mouth open.

Yu Zai also immediately looked at it when he heard it. When he was about to ask Li Heng what was going on, he also showed a look of shock.

And the firefly, who was opposed to finding Su Lifeng, suddenly contracted its pupils the moment it turned its head...... Su Lifeng actually came back with a corpse......

Part of the corpse that had been dissected, to be exact, with two hideous, blackened spider legs. and a long tail pin.

The cold-as-a-frost female soldier was wiping the dagger she had just used, and at this time, she couldn't help but glance at Su Lifeng more.

"You...... You actually killed her......" It wasn't until Su Lifeng walked up to him that Yu Zai finally came back to his senses, pointed at him and said in horror, "And you're not a strength type either!" ”

"I've never said that, it's just you who think so." Su Lifeng carefully put the dismantled limb on the ground, and then untied the backpack from his back.

"You're going to bring these back?" Yu Zai asked.

Although he didn't say it explicitly, just by looking at his expression, he knew that he thought these things were terrifying and disgusting.

At first glance, these parts are very similar to familiar creatures, but the details and sizes have nothing to do with the creatures of the earth. And human beings are interested in subverting their own perceptions. In fact, there is an instinctive sense of resistance.

"Yes." After Su Lifeng finished speaking, he saw that everyone was staring at him with a crazy look, so he had to sigh and add, "Don't forget, I'm actually a student of biology ......."

"Oh, yes." Looking at Yu Zai's expression of sudden realization, there is a kind of meaning of "If you don't say it, I will forget that you are actually a polite graduate student".

The female soldier also looked at Su Lifeng with some surprise, but then she heard Su Lifeng say like a few treasures: "These parts are the most complete of her abnormal transformation, but in fact, if I can, I hope to bring back her complete body." You may not know. She even has the ability to reproduce......"

"Descendants? You mean...... That kind of monster can still reproduce?! Li Heng's scalp was numb and he said in horror.

Su Lifeng glanced at him, zipped up the backpack that had already contained these limbs, shook it, put it back on his back and said, "Don't be so surprised. I said yes, but I didn't say she would. In fact, it is still unknown whether xenomorphs will produce offspring through this sexual reproduction. And in her case, whether she should merge with spiders or humans, no one can say. Assuming it was a spider, would there be such a big spider to match her? That hypothetically is human...... Alas. If she was able to reproduce, it would still be scary to think about. ”

The female soldier looked at him stunned, while Li Heng and Yu Zai shook their heads desperately: "No, we think it's still you who is more terrifying." ”

"Tell me, how did you know she was still ...... to reproduce?" Yu Zai asked sharply.

Su Lifeng was silent for a while, and then silently walked to the front and said, "Isn't there still a task?" Let's go. ”

These people have no idea what serious scientific research is......

The two spider legs were very hard, and after Su Lifeng scraped off the corrosive liquid on them with a knife, he found that if he could make such a thing into a weapon, the effect would definitely be better than that of a knife, although it was not suitable for him.

And the poisonous needle made him think of a person immediately.

If it's used for her, the effect should be very good, just to make up for her lack of attack power.

For thermal weapons, Su Lifeng always had a sense of awe. In the hands of the army, this thing can play a very powerful role, but in the hands of ordinary people, once there is a problem, or if the ammunition cannot be replenished in time, it will be difficult to play a real role.

So just in case, Su Lifeng always wanted to find a more suitable means of attack for them.

On the way, he looked at the female soldier from time to time, and the other party also seemed to notice that Su Lifeng was looking at him, but she still looked expressionless.

"The army and the survivors have a large population base, and she is already using the awakening ability with impunity, does it mean that this ability is already recognized in the quarantine area? Or is it ...... Was she the first person to eat crabs? Su Lifeng thought to himself.

Just as he was thinking about how to ask to get an accurate answer, the firefly, who had not spoken since he returned, suddenly snorted. (To be continued.) )
