I remember the last time, I followed my grandfather in panic, like a little tail, for fear that my grandfather would disappear from me in a blink of an eye.

Now, when I walked into the cave again, I relied on my own efforts. I silently recited in my heart, Grandpa, I did not disappoint my promise, I did it.

I took a step slowly and walked into the cave. At this time, the snow outside the cave reflected the sky light and shot into the cave, so it was not too dark here.

At least, even if the oil lamp in the cave has been turned off, I can clearly see the surrounding scenery.

In the narrow cave, there are straw mats and futons on the ground, and there is a stone pier next to it. On the stone pier, there is a small oil lamp, but the oil inside has long been exhausted, and there is still darkness in the depths of the cave.

Grandpa, but he is not here either.

But there were obvious signs of sitting and lying down on the straw mat. I squatted down in confusion, reached out to look at the straw mat, and picked up a piece of gray hair, about two inches long.

I felt a little moved and looked carefully. My hair was obviously my grandfather's, but I clearly remember that when my grandfather left, my hair was definitely not so long. This shows that my grandfather not only did not die at that time, but also lived in a cave, and at least he lived for two or three months.

Because looking at the length of this hair, it is impossible to grow so long in two or three months, but from then on, it has been almost half a year. Where has my grandfather gone for the remaining months?

I stood up and looked around in the cave.

The cave is not too big, and it will be checked in a short time. However, there is nothing else in it except the straw mattress and stone cushion, and the stone piers, except for the four stone walls.

It's so strange. I stood at the entrance of the cave, dazed. Judging from the situation where I broke the hole just now, it shouldn't have been opened, because it doesn't make sense. If my grandfather had cracked something and no longer needed to seal the cave, then after returning home, there would be no reason to just put down the pipe, come back, and seal yourself in the cave again.

This does not conform to the behavioral logic of normal people.

If my grandfather wants to tell me something, he can also leave me a letter. If my grandfather leaves, there is no reason to leave his cigarette pouch, because it is his forbidden object, a forbidden object that uses prohibition laws.

But if grandpa really went home and then came back to the cave, why was the entrance to the cave closed but he was not inside?

My mind was messy, and these problems were like a mess, tangled together, and I couldn't straighten it out for a while. I subconsciously sat down on the cushion, staring at the entrance of the cave in a daze.

A thought suddenly flashed in my heart. No, it might be that my grandfather didn't seal himself in the cave at all. It might be that my grandfather had disappeared after leaving me that letter. His cigarette pipe was always in the hands of others and was placed on the table at home, just to lead me to the mountain and then to deal with me!

But this is not right. If so, how can I explain the hair in my hand? Could it be someone else's?

I couldn't figure it out, so I put my hand on the stone pier next to me in wonder, and subconsciously knocked on it, thinking about the whole thing in my heart.

Suddenly, my hand accidentally touched the small oil lamp on the stone pier. I was stunned. Although the strength I used just now was not strong, it was probably enough to knock the oil lamp down. Why was the oil lamp still motionless?

I turned around and saw that the oil lamp seemed to be made of copper. It looked a bit old, but it could not be connected to the stone.

I reached out to grab the oil lamp, shook it slightly, but unexpectedly found that I couldn't shake it at all. The oil lamp really seemed to be connected to a stone!

My heart moved, and I jumped up quickly. I grabbed the oil lamp with both hands and tried to pull it up a few times, but it still didn't move at all. I tried to turn left and right again, but this time, it actually moved!

I was overjoyed. A copper oil lamp connected to a stone cannot shake or pull it up, but can rotate left and right. What does this mean?

There must be a secret passage in the four walls of this cave!

I immediately grabbed the oil lamp, left and right, right, left and right, left and left, and repeatedly tried it. Although I had no reaction after turning it for a long time, I knew that it was a way I had not touched it. Since the oil lamp was strange and grandpa disappeared from this cave, there must be problems.

However, I tried for a long time without any discouragement, but still had no response. I neither heard the expected mechanism, nor did I hear a special sound in the mountain wall or somewhere under my feet.

This was not right. I stood up in wonder, grabbed my hair, ran to the four walls of the cave again, picked up a stone on the ground, grabbed it in my hand, and started to hit the mountain wall with jingling.

If there are empty sounds or obvious traces of mechanisms, I should be able to find them.

While knocking on the stone wall, I leaned over and listened carefully. At the same time, I reached out and stroked around the mountain wall. I didn't even have any idleness under my feet. I was kicking hard on the ground. Maybe there was a hidden secret passage somewhere underground.

However, I insisted on knocking the four walls of the entire cave, and even stepped on every inch of land under my feet. After checking, I still found nothing.

This cave is like a rice cooker with excellent seals, without any gaps or holes, and no traces of mezzanine.

This was really strange. I walked to the stone pier again and stared at the oil lamp, thinking to myself that the problem might still be on the oil lamp, but how can I find the right way?

I was staring at the oil lamp in a daze, but at this moment, a bright light suddenly lit up on the oil lamp.

I looked back and saw that the afternoon sun was dazzling, shining on the snow outside, reflecting a very dazzling light, just so it was projected on the oil lamp.

For some reason, the light on the oil lamp was refracted obliquely upward, but it just shone on a corner of the stone wall. From a distance, it seemed something strange there was.

I hurriedly walked over. The position was just parallel to my sight. At this time, under the reflection of light outside the cave, I could clearly see that there was a piece of stone wall about the size of a finger, with a dark red color on the stone wall there.

I was secretly happy. If something was wrong here, then God would help me.

I reached out and touched the place, and found that it was a groove. I did not hesitate and immediately pressed it with force. If this was the hub of the mechanism, it would be a coincidence.

However, this time, it didn't press it. It seemed that it was just a hard stone. Judging from the feel of the hand, it shouldn't be pressed.

However, if you can only press such a sunken place with your fingers, is there any other way to open it?

Or, this is just an ordinary stone, and the reflection of the light is just a coincidence?

No, it was not that simple. I took my finger back, put it in the light in confusion and looked carefully, then put it at my nose and smelled it, but my heart suddenly moved.

There were a slight red mark on my fingers, and there was a very faint, bloody breath!

That's right, it's the breath of blood. Over the past few months, I have been dealing with blood, and it's all my own blood. I not only know the breath of blood, but also the color of blood. Now the blood stained on my fingers should have been a long time, but the hole is wet after all, and the blood can be clearly identified. It's absolutely impossible to be wrong.

There are traces of blood in such a small groove. What does this mean?

Of course I don't know, but I can give it a try!

I just fucked it. I put my fingers in my mouth, took a bite, and blood immediately flowed out of my fingers. I hurriedly put my fingers in the groove and squeezed them hard, so I watched my blood slowly flow into the groove.

My heart was pounding, and I wondered if this would work. After my fingers stopped bleeding, I quickly took two steps back, held my breath and carefully observed the changes in the mountain wall.

But I waited for a while and there was no movement. I thought about it carefully and suddenly realized that I hurriedly walked over again, stuck my finger into the groove, and pressed hard...

Suddenly, a faint sound of rotating clumps came from my ears.

Crack... Crack...

I widened my eyes silently and saw a mountain wall next to me slowly opening a secret door...

There seemed to be a wind blew out from it.
