Looking at the fat man who hugged the black mallet, he also rolled his eyes speechlessly, the mallet fell to the ground and waited to smash a pit on the ground, when we used the mallet to smash the hole just now, I also paid attention to it, and there was no trace left on it.

The fat man grinned at me and stood up, packed up the schoolbag under his feet, and said to me: "Fat man, I will take the lead, you follow me, fat man, my back will be handed over to you today, and our revolutionary friendship has officially begun." ”

"Let's go!" I smiled and raised my head at the fat man.

The fat man raised his flashlight and looked at the stairs in the cave first, then put his head into it, and then said: "Damn, I didn't expect it to be so deep, be careful when you come down." ”

Although the hole has been smashed by us, the fat man can only barely squeeze into it, and if it is any smaller, it seems that it will be stuck.

After a head poked in, I found that it was really as the fat man said, the hole we smashed out now is about a meter away from the stairs below, although it is not very high, but after all, I have to come in on my stomach, so it will be very uncomfortable, the fat man took a handle and dragged me in directly.

Inside, I first held a flashlight and looked ahead, and found that this passage is much shorter, only about two meters, which allows people to walk upright, but the top of the passage is more than ten centimeters away from the head, giving people a very depressing feeling.

The two sides are very wide, more than three meters, this passage now gives me the feeling that it is flat, the walls on both sides are pitch black, without any patterns and words, as if it has been smeared with a layer of things that can absorb light, this flashlight shines forward, it seems that you can only see the distance of more than ten meters in front.

Once the walls are painted with something that absorbs light, it is very uncomfortable, and it feels very strange, always feeling like disappearing at the end of the sight, as if something is about to pop out.

"Why are you so short, if that soldier brother comes in, he won't have to bend his neck to walk." The soldier brother that the fat man said should be Liangzi, and I don't know how this guy and Ge Lao are doing now, the injury should be almost better, maybe he has returned to the army.

"We don't have to bend our necks to walk, I always feel that this passage is not quite right, you should be careful, don't capsize in the gutter later." I looked at the fat man's back and said.

The fat man walked very slowly, and both of them walked cautiously, and walked like this for about fifteen minutes, and there was still no end in front of him.

"Something is wrong...... How can a tomb during the Qing Dynasty be so large-scale? Is it still a prince's tomb? "I'm starting to feel a little uneasy, after all, after walking in it for ten minutes, if I'm outside, I'll walk through the street.

The fat man's face was a little wrong, and when I finished speaking, I noticed that he had been staring at the corner, so I asked, "What are you looking at?" ”

"We've been here just now......" The fat man's brows tightened, and then he ran to the corner of the wall, and when I looked at it, I found that there was a cigarette butt in the corner, and it was really hard to find it if I didn't look carefully.

The fat man squatted on the ground, picked up the cigarette butt, looked at it and said, "I smoked it just now...... We're back here again. ”

"Are you sure you just threw it?" I looked at the cigarette butt in the fat man's hand, and said with some astonishment, you must know that we didn't go to a fork in the road just now, and from the perspective of logic, this is simply impossible.

"Sure! Who else can there be in this place besides us, and the brand of this cigarette, and the location of the throw, I'm sure it was I just threw it, it's weird, we haven't taken a fork in the road, why did we run back again? As he spoke, the fat man squeezed the cigarette butt in his hand violently, and it was still on the ground again.

"Go further and try it!" I'm a little unconvinced, after all, we've been going down in a straight line, and no matter what angle you think about it, it's impossible to turn back to where we've already walked before.

The fat man nodded, slammed the mallet against the wall, and then continued to walk forward, still leading in front, I followed the fat man, all the time leaning sideways, observing the situation behind the person, and soon, the position of the cigarette butt just now disappeared into the darkness.

What made me desperate was that ten minutes later, I saw the fat man walking in front of me jump up all of a sudden, pointed to the mark on the wall that was smashed by a black mallet and scolded: "I'm grass his grandma, look!" We're back again! ”

I looked at the marks that had been smashed by the fat man, lowered my head and looked for it, and found the cigarette butt that the fat man had pinched in front of me, and suddenly a chill began to spread from the soles of my feet.

"Impossible...... What the hell is going on? "It was unbelievable that we didn't go through any forks in the road, kept going down the stairs, and we just went around and back.

"We shouldn't have encountered ghosts hitting the wall, the evil door in this ancient tomb, I didn't bring the black donkey's hooves this time, I didn't expect the fat master to encounter ghosts hitting the wall, let me think about what to do when I encounter a ghost hitting the wall." The fat man sat down on the ground with no fear in mind, and began to ponder as he rubbed his thighs.

I took a deep breath, kept myself calm and thought about it, and said: "It's not a ghost hitting the wall, the ghost hitting the wall is wandering in place, being blinded, let's spare it alive, it shouldn't be a concept." ”

This kind of thing is actually a hazy state of human consciousness from a scientific point of view, this kind of thing generally happens at night, and this point is usually the time to sleep, so the subconscious mind is hazy, and it is easy to circle around, or directly step in place, and from a supernatural point of view, it is to be blinded by ghosts, and everything you see is your own hallucination.

I thought about it and ruled it out, and my head began to spin wildly, wondering what was going on.

It's always going down the ladder, and it's all in a straight line, which is absolutely impossible logically, so if we want to go back to where we are, the first two assumptions are wrong.

Thinking about it this way, I have to rule out that we are going down, and we are not walking in a straight line, only in this way can we be established in space, and in three-dimensional space, it is impossible to go all the way down, and we can return to the original position.

Thinking of this, I lowered my head and carefully looked at the wide, long, but not high staircase under my feet, and when the light of the flashlight shone, the staircase did not reflect the light, but absorbed some of the light.

Then I looked at the wall twice, and a picture suddenly popped up in my mind, which was something I was curious about studying and playing a few years ago, and I remember that when I was about to take the college entrance examination, I didn't review it well, so I studied some messy things.

"Fatty, do you know the Penrose Steps?" I looked at the fat man and said.

"What silk? Fat man, I know Prometheus, the mystery of the origin of mankind...... What are you talking about, what screws? The fat man was still thinking about how to crack the ghost wall, I asked, looked up at me a little puzzled, and asked.
