After walking for about ten meters, the lights behind him were already very dim.

According to the human light sensing system, there is no way to tell whether you and the focused lamp are in a straight line.

I walked forward slowly, but I didn't dare to speak.

About 100 paces later, we reached the front of a stone wall.

When I looked up at the wall, I realized that the huge wall could not be opened at all.

The walls are made of granite, which is very hard.

When Chad looked at it, he realized that it was a large stone wall, and it could be said that there was not even a gap.

I know that this kind of stone wall, if you want to call it in professional terms, it should be called a jack pendant.

Jack pendants are actually rare.

Because according to the technology of the ancients, making a jack pendant is not something that can be completed in three days and two ends, and it is necessary to cut a stone from the stone mountain intact, and then carefully polish it and then stuff it in.

This "plug" is knowledgeable, because the tunnel mouth is so large, there is no way to transport such a large wall, so many places are to cut the jack pendant and move it in, and it is assembled inside. For example, the Empress Dowager Cixi's bedroom was a jack pendant, which could not be opened in the end and was collapsed by a cannon.

And the huge wall in front of me is a jack drop.

It's not up to strength at all, and if nothing else, there should be a mechanism here.

And based on the beam coming from behind, it can be seen that there should be an absolute correlation between the mechanism and the beam.

Uncle Biao was pestled in front of the stone wall, his hands pulling at something on the stone wall, but I wasn't very close to him, so I couldn't see what he was doing, maybe he was debugging the password or unlocking the mechanism.

However, from his sigh a few minutes later, I seemed to feel that Uncle Biao couldn't unlock this mechanism, because the jack pendant didn't move at all.

The question is, what's inside this jack pendant?

A treasure full of gold and silver? Or some untold secret?

I suddenly had a idea, it can't be Jiang Ziya behind this wall, right?

However, according to the current situation, I think Uncle Biao's technology is not suitable for entry at all, otherwise it will be looking for death.

Uncle Biao stood in front of the stone wall for about ten minutes, but he didn't notice any movement.

Suddenly, I saw him turn his head to look at the beam behind me, then pat his head, and return to the bronze mirror.

Am I grass? What's going on? Do you feel like you're following the beam of light?

At this time, Uncle Biao took another step and walked cautiously to the side.

It seems that he walked very carefully this time, and he looked back after almost walking a dozen or so steps, probably for fear that he would deviate a little.

I looked at Uncle Biao's every move, and I felt very funny, and I had an idea in my heart, although the switch of this beam to find the mechanism is a bit clever, but it is still easy to be discovered, and it is still very conspicuous.

Whites like this can see the mystery of such a mechanism, and it is not difficult to suspect that this thing should be a heuristic mechanism.

When it comes to heuristic mechanisms, it's actually quite ingenious.

It's the kind of mechanism that you seem to be able to crack easily, and you can still do it according to your own ideas, but when it comes to the last step, you will fail to crack it or be injured by this kind of mechanism.

Watching Uncle Biao repeat it over and over again, every time it was in vain, I firmly believe that it is definitely not so simple to open the jack pendant.

Although Uncle Biao is very old and spicy, it is precisely because of this that he can easily fall into the trap of this heuristic mechanism.

This lamp and distance is a trap that you will always repeat but never complete.

I watched Lao Chen walk back and forth over and over again, and I really didn't know whether to be happy or sad at this time.

Whether this person dares to put "me" on the slope with confidence out of selfish desires or other reasons, it is completely unjustifiable on this point.

If it's me, even if it's back, I'll be with my companions.

About an hour later, Uncle Biao stopped and sat on the ground panting, and it was obvious that his physical strength had reached its limit.

Taking advantage of the splashing light, I could see him sitting on the ground with his head drooping, covering his face, as if he was frowning.

Now that I think about it, I'm starting to get a little angry, I came to find you for Xiaohua, and it was good to me at first, and how did I walk in front, but now it seems that this is in the way of me, and at the critical time, it knocked me out.

I just stood a short distance from him, watching how he would perform next, whether he would go back or how he would drop.

After about ten minutes or so, Uncle Biao stood up and sighed, it was obvious that he couldn't do anything about holding the huge wall.

I thought he was going back, and followed him back to the slope, where my body was also lying.

I saw him rummaging around again, and after a while, he finally found something wrapped in an oilcloth and took it out.

The thing was not very big, but I could see that his expression was very solemn.

I watched as the thing was opened layer by layer, and I couldn't help but gasp, this thing turned out to be a bunch of high explosives, which is what we often call directional blasting explosives!
