"Since it's a ghost hitting the wall, we have unconsciously turned back, that is to say, between us moving forward and turning back, there will be a node, and the ghost who is a ghost is on that node!"

So, the question now is - how do we find the node? As long as this node can be found, then the problem is easy to say.

"Wait, what do you mean, we've established now, is this a ghost hitting the wall? Isn't there any other possibility? ”

It was He Chuxue who said that the ghost hit the wall, and she was the one who objected. Perhaps, she couldn't believe that we had adopted her rookie advice so easily.

"If you still want to make sure, the road is not long anyway, we can walk it again, this time, we are all carefully watching the surroundings, maybe we can find the node."

The three of us are still in the order at the beginning, I am in the front, He Chuxue is in the middle, and the cold frost and rain are in the back. The only difference is that in order to prevent accidents, He Chuxue dragged my clothes with his hands, and Leng Shuangyu and He Chuxue only saw each other, and they also had their own ways of contact.

This time, we walked more carefully, ashamed to say, it was the third time to go, I vaguely felt that the road was a little uneven, to be precise, it was a little downward, but this downhill was exceptionally gentle, if I didn't pay special attention, I'm afraid I still can't notice.

"You feel it, right? The road is downward. ”

I didn't say that at first, but after walking for a while, I still felt like I had to remind them that it wasn't necessarily possible if the two of them could think of anything.

But who knows, as soon as I finished speaking, He Chuxue let out a puzzled cry, she pinched my waist and retorted to me: "Why do I think we are on the top...... What do you think, Sister Leng? ”

Cold Frost and Rain was silent for a while, as if patiently perceiving, before speaking: "I also think that we should be going uphill, although the slope is very gentle, but I shouldn't feel wrong." ”

Let them say this, I feel a little wrong, we were obviously going downhill just now, this feeling, normal people don't feel wrong, but now, how can I feel that it is uphill?

Damn, I must have just sensed that it was going downhill, so all I thought about was downhill all the way, no, even if it had already started to go uphill, my mind was still downhill, so even I was dizzy.

I cursed and said to myself, I must not know where, we had missed that node, and now, we began to walk in the direction of the cave again.

I stopped, and the two of them sensed something was wrong: "What's going on?" Have we already come along? ”

I nodded, and analyzed that the well water must have flowed up from a low place, but this well is only about six meters high, and it is obvious that compared with ordinary wells, this depth is far from enough, so this passage must also be downward.

There is no reason to go all the way down and then up again, and then the slope loses its original meaning.

"So what do we do now?" He Chuxue rubbed my clothes, looking a little nervous.

Actually, that's what I'm thinking about, what do we do now? Do you keep going, go out, come back, or go back?

"You say, if we keep going, it's the way out, then if we go back, will we be able to get where we want to go?"

The cold frost and rain thought of it with me.

"That'...... Let's go back and try it! ”

We made a U-turn and also changed direction because my left hand was injured and I had to use my right hand to hold the wall.

This time, I almost looked down at my feet, indeed, we are now going downhill, the only difference is that this time it was the cold frost rain that went first, and I walked last.

We walked for a while, and the cold frost and rain stopped again.

And I said to myself, What has happened again? I feel very clear now, it's going downhill!

Unexpectedly, Leng Shuangyu took out his small bag and took off a coat. She only wore a suspender belt inside, and just looking at it from behind, it felt sexy.

He Chuxue turned her head and glared at me fiercely, her expression was very serious, I quickly lowered my head, and silently thought in my heart, don't look at incivility, don't listen to incivility......

Leng Shuangyu found a piece of rotten wood from the ground, wrapped her clothes around it, and then took out a small bottle from her waterproof bag and poured all the liquid on her clothes.

I guess the bottle must have been filled with alcohol.

Sure enough, after doing this, she took out her lighter, lit a cigarette for herself, and then lit her clothes, which became a simple torch.

It's just that this hole is narrow, and even if there are torches, they can't be placed vertically, as long as the cold frost and rain are held flat, and the torches are facing forward.

"You're smart!" I'm bored, and I don't have anything to say. Strangely, they both ignored me, as if they hadn't heard.

I took a breath and was about to continue talking, but He Chuxue suddenly turned around and told me with a smile: "Don't talk, carefully observe the surroundings!" ”

I nodded and looked at the wall, and suddenly a thought came to my mind: "You say, if we draw a mark on the wall, for example, if we draw a line all the way, then if we actually pass through a node, on that node, won't there be a mark on the opposite wall?" ”

I patted my head and blamed myself for not having thought of this sooner. However, Leng Shuangyu suddenly said: "There is another thing that is very strange, if it is true that we are passing through a node, the three of us can no longer be simply described by points, to be precise, I am a line ......."

I understood what she meant, she was trying to say that if we really just pass through a plane, a point, we will pass through, but the line is different, the line has a length. In other words, if I was the first to cross that node, then when I walked back, the cold frost and rain had not passed through, wouldn't I meet her who was still behind the node?

However, we didn't encounter it, so what is going on? Could it be that this is not a node, but a distorted space?

Thinking about it, I shuddered coldly, it's really terrible, the more I think about it, the more scared I become, if this node is thin enough, wouldn't we be able to see our ass without looking back?!

"So, there's another possibility, this node is very thick."
