Return — The Sewer Signal

I know the door's locked. I'm just overthinking. It's always locked when I go back. I'm really not going back.

I know the door's locked. Damn it. I can't break this habit. I still have to check.

We need to investigate. It can't be the wiring. We've been looking all night. That's the only clue we found.

Let's go now. Alright, let's go. Go. The wire in the footage.

It's right here. Yeah, exactly here. But I don't see any wire. The wire's landing point in the footage.

It's these two buildings. Yeah, let's go up and check. Why does it stink so bad here? Can sewage smell this bad?

No. This isn't your usual sewer stench. Rats couldn't cause this. And not people either.

Farther ahead. The water flow is slowing down. The air's warmer too. Up ahead is the first fork.

Take the right. Wait. The cats and dogs dumped above. They probably all ended up here.

Careful. Molted shells of mutant ants. And not just one. Why are they so different in size?

Maybe their size and diet also vary. Let's keep moving forward. Commander, can you hear me? Go ahead.

The drone spotted bodies passing by. I saw a faint glow. No, it's a group. Distance.

Directly ahead of you. They're fast, about a hundred meters. Subtitles: Li Zongsheng
