"Does this really have to go here?" I looked at the sewers of the black hole and felt a little worried, although it was said that walking here could hide our whereabouts, but I always felt that there was danger and murder lurking in the darkness.

"Don't talk nonsense, I'll go down first, don't leave the second, Mecca third, and after the Cliff Palace, I'll go down first to make sure it's safe and then you can come down."

Wolf Fang turned on the flashlight as he spoke, holding it to his mouth and tentatively stepping on the ladder into the sewers. In order to find such a sewer with a ladder, we also rummaged through a lot of manhole covers to find it.

Shortly after the wolf's fangs were completely hidden in the darkness, his cry came from below, "It's okay down there, don't leave, come down." ”

Hearing the wolf's fangs, I stepped on the ladder into the sewers, and climbed down a little by little by the light shining from the flashlight by the wolf's teeth.

This sewer should have been built for some years, and you can feel the iron filings falling when you hold the ladder tightly, so it should be that the ladder is a little corroded and rusty. The last time I climbed such a ladder was because I lived in the upper bunk of my dormitory when I was in college, and it has been several years since I graduated from college, but I haven't climbed such a ladder again.

"Anyway, look at it."

The sound of wolffangs came from behind me, and I lowered my head as I said, and found that I had stepped on the last bar of the ladder and jumped off it.

After that, Mecca and Limya also descended from the ladder in turn, and the four of us met up and moved along the pipe according to the instructions on the tracker.

Only the footsteps of a few of us could be heard in the pipe. Maybe it's because it's been unused for a long time, and there's not much sewage, so it's slightly damp.

It's just that I always feel that something is wrong, but I can't tell what is wrong, and the uncomfortable feeling of ignoring something important has come again, but I still can't remember what I have overlooked.

It's so quiet in this pipe, so quiet that it even makes me feel a little weird, and my heart beats unconsciously faster.

"Do you think there's something wrong here? I finally couldn't help but say, looking around to find out what was strange to me.

"Strange? Do you mean the smell? It's normal to have some weird smells in the sewers, nothing strange. ”

We came to a crooked point, and Wolf Fang answered me as he stopped and drew something on the wall. From the moment he entered the place, he made a mark on the wall every time he came to a corner, and this was the third one.

"Still, if there's anything strange, the walls here are strange, a little soft, the marks are hard to draw, and if you push too hard, they will sink in and debris will fall." Wolf Fang said, reached out and pressed it against the wall, easily buckled off a piece, put it on his hand and twisted it, turned around and spread his hand out in front of us to show it, "You see, the material of this wall is a little strange, it is all composed of this small strip of small particles, I don't know what kind of material it is." ”

I reached out and took some of the wolf's hand and put it on my hand, watching it carefully in the light of the flashlight. As the wolf's tooth said, they were small black strips, wet and soft, and could be easily crushed with your fingers. I endured my nausea and sniffed closely, it smelled the same as the smell in the sewer, only stronger, I don't know if its smell was emitted into the sewer, or if the smell in the sewer was absorbed by it.

"It's probably dirt or something, and it is estimated that no one has cleaned it up for a long time, and it is normal for some dirt on the walls to adhere to it." Lin Ya also looked at the black particles and guessed and said, "Let's go quickly, the location of the key displayed on the tracker is still some distance, hurry up and find the key and come back quickly, after all, there are many dreams at night." ”

Wolftooth nodded and walked forward again according to the location on the tracker, and based on the distance above, we were already halfway there. I was expecting to see some kind of underground river with stinky water, or sewage that we need to pass through, but none of that happened, and we found a way to walk every time we needed to change direction, and we were so lucky to have it so smoothly.

It's just that this is too smooth a journey, but it makes me a little uneasy, and I always feel like everything has been arranged, not help, but conspiracy.

I hope I'm just worried.

But what's the matter with this feeling of mine, the feeling of being targeted before seeing the wolf's fangs has reappeared, and it is not as strong as before, but it still makes my heart hairy, and a layer of cold sweat oozes from my back. But wasn't that because the wolffangs were secretly following me? Now he's ahead of me, is that my delusion?

"Sister Mo Li"

"What's wrong?"

Hearing Mecca's voice, I turned my head slightly and asked casually, the feeling of being targeted was getting stronger and stronger, but I was not sure if it was my delusion, and I was so irritable that I was in no mood to respond to Mecca.

Yuguang saw Mecca shrink her neck slightly, swallow her saliva, look around and whisper to me, "I feel as if something is following me." ”

Hearing this, I subconsciously paused, only to find that Wolf Tooth and Lin Ya also stopped together to look at me and Mecca. Did Mecca feel it too? That's not my delusion

"I thought it was my delusion, but you felt it too." Lin Ya said to Mecca, looking up at me and Wolffang, "I feel the same way as Mecca, what about you?" ”

"I have it too, and it's not the first time, I felt this way before I met the wolf fang, and I thought it was the wolf fang stalking me that made me feel this way."

I replied to Lin Ya's words, because I felt nervous and afraid, my hands were clenched at some point, and my palms could feel slightly sweaty.

"I've felt this way before, and I thought it was a delusion." Lin Ya said.

Mecca chimed in: "I felt this way when I was in school before. ”

That's not my delusion! The reason why I've been haunted by this feeling before can't be because the wolf fangs are following me!

I was thinking about it when Wolf Fang, who had been listening to our exchange in silence, spoke.

"I didn't follow you, and as soon as I saw you, I walked straight to you." Wolf Fang said as he took out the knife on his body and held it in his hand, "And the feeling you said, I also had it when I first entered here, and now that I think about it, the ones who are staring at me and you should be those rats." ”

I suddenly connected all the joints, why I felt like I was overlooking something, why I felt like I was missing something from the plan in the first place, why I felt strange here, why the walls were soft and smelly, why the journey went so smoothly, why this feeling of being stared at was getting stronger and stronger

"Soon after I entered here, I found out that we were being targeted, but I was afraid that you would panic, so I didn't tell you."

Wolf Fang guarded the surroundings with a knife, and stood still and did not move any further. Although his tone was calm, what he said made me feel a sense of panic when I heard it in my ears.

"Are you saying you already knew it was a trap, but you still took the initiative to drill into it?" I was shocked, not understanding what Wolf Fang was thinking.

"Trap?" Wolf Fang looked at me and asked curiously, "Do you know something?" I didn't know it was a trap, but whether it was here or on the ground, we would be targeted by the rats, at least the space here is relatively narrow, and they are not easy to use to their numerical advantage, so even if they find out about our existence, I will simply continue to move on here, I think it will be better than outside. What do you mean by snare? ”

"Better? It's so good that we went straight to the base camp where we killed the rats. The nervousness and fear sent chills through my body, and the feeling of being stared at intensified, and I even had the illusion that there seemed to be a pair of eyes full of blood and murder everywhere, waiting for the time to tear me apart, "It's a trap, those rats brought us here." ”

"The rats told us to come here? What does that mean? Lin Ya also took out the knife on his body and guarded, and at the same time asked me, motioning for me to continue.

"Except for the time when Ho Yan was killed and Mecca was in distress on the rooftop, we didn't see rats at any other time, right? This shows that the rats spend very little time on the ground, and more time not on the ground, such as underground," I tried to calm myself down and clear my mind and explain to them, "and the whole city, many of them were killed in their rooms, but the doors were not damaged, which shows that the rats had a way of entering the room that we didn't know about." ”

"These huge numbers of rats need a place where they can hide on a weekday, and this place is underground, so it's easy to guess that this is where we're standing now - the pipes. And the pipes that connect every corner of the city, every toilet is connected to the sewer, and they also enter people's homes through these pipes, and then kill them and transport corpses. I continued to analyze according to my own speculation, and the more I analyzed, the more I found that my speculation was completely consistent with the facts, "And He Yan's body disappeared in front of the wolf's tooth eyes, also because of the pipe." I remember that in the place where He Yan was killed, there was a well, which is why the body disappeared as if it had been buried in the ground. ”

"What about the trap? You mean the rats brought us here? Why do they do it? ”

Wolffang asked with a frown, and it was clear that he also thought my guess was right.

"The walls here are not ordinary building materials, but rat droppings." I thought about the fact that I had touched and smelled the rat droppings with my hands before and felt a little sick to my stomach, but now is not the time for me to be hypocritical, "I felt something was wrong when I entered here, but I never figured out what was wrong before, and I just thought it out because there was no response here." ”

"With such a large passage, it is logical that there will always be an echo, but the sound of our footsteps does not echo here. This is because the texture of the rat droppings is relatively soft and moist, and it absorbs the sound, so there is no reverberation. ”

"And if these walls are made of rat droppings, then it means that the roads we are walking are all built by those rats. It's not so much that we've gotten here ourselves, it's the rats that have led us here. ”

"As for the purpose, I assume that they have undergone some intellectual evolution as a result of mutation, then there are only two possible reasons why they have brought us here. One is that the researchers were there before, and they knew what was appealing to humans. The second is that this is where they hunt and eat, and the keys are brought here with the corpses of the researchers. ”

"So, if I'm right," I said, taking a deep breath and uttering my reasoning, "we're going to be attacked by the rats when we get into the area where the key is." ”
