The place where Wukong and the others are now is in a huge underground canyon about two hundred meters above the ground.

On both sides of the canyon, there are steep stone walls as smooth as mirrors, the difference is that on the stone wall opposite Wukong and the others, there are hundreds of irregular spots of light of different sizes, emitting this green light, but the stone wall behind them does not have this situation.

However, the stone walls on both sides are extremely slippery and steep, and it is impossible to climb without tools.

According to Wukong's experience, it is speculated that there are at least two waterfalls tens of meters high in the upper reaches of the underground dark river, and it is unknown whether there are any waterfalls in the downstream of the stone platform that is 100 meters long and 20 meters wide where they are standing at this time, after all, the downstream is pitch black, and nothing can be seen at all.

The reason why Wukong met Liezhenbei and others underground, the reason is very simple, this artificially excavated 100-meter stone platform is the Shuangxiu Mansion fifty years ago...... , build a secret black prison!

Every day around the morning, a hundred meters above the stone platform, a large square basket would be lowered, which contained enough food for all the prisoners for a day, and a full thirty candles.

The only way to get out of this terrifying underground stone platform is to sit in that big basket and be pulled up from above, and there is no second way for prisoners who have already eaten the lock pill and don't have any tools.

If you want to sneak into the big basket and then climb to it with a chain while you are delivering items every day, of course, you can, but it is useless to do so, because once you find out that the weight is wrong, the person above will immediately pour fire oil below.

Even if you are lucky enough to climb up, it is still useless, because the prisoners who have no combat power will definitely not be able to pass through the small room guarded by two jailers who have returned to the ninth level.

Like this kind of terrifying black prison, there are seven more in the cities of the two states, and the history of a hundred years has proved that no prisoner has ever been able to ...... from this kind of black prison and escape!

However, since these black prisons were built, in fact, there have not been many people in total, and this secret black prison under Chang'an has been built fifty years ago, and Lie Zhenbei and others are the first batch of prisoners here.

The reason why the Western Buchen chose to detain them here is actually very simple, just because the environment here is the best among the eight underground black prisons!

That's right, this kind of ghost place where you don't need to wear shackles, you can eat and drink every day, and you can still move and move without seeing the day, it is the most comfortable black prison.

However, what the successive lords of the Shuangxiu Mansion did not expect was that they all thought that the Chang'an underground black prison with the best living environment and impregnable living environment was more than 20 years ago...... , there was a major accident!

And this accident is a precious opportunity for Lie Zhenbei and others to try to escape from the black prison.

"My lord, hearing you say this, I finally understand the source of those tools. After saying in a low voice, Lie Zhenbei pointed to the corner, hundreds of various stone drilling tools.

When they were just sent down to the stone platform, they discovered a strange thing, that is, there was not only a dry skeleton with a broken leg on the stone platform, but also a pile of neatly arranged ...... , a variety of small stone drilling tools.

In this dark prison, these things were discovered, which really made Lie Zhenbei and the others, who had just fallen into trouble, both surprised and completely confused.

Then they found that there were two rows of extremely regular, upward climbing holes in the stone wall opposite the dry bones, so one of them continued to climb along the small holes until it was about forty meters high, and there was no more hole to climb up.

After the man came down, everyone speculated about the identity of the owner of this dry bone that had been dead for 20 years, and why he would risk his life to dig out two rows of escape holes in this unused black prison.

This person is definitely not from the Double Cultivation Mansion, let alone a prisoner or jailer in the Black Prison, the reason is very obvious, the upward escape path he carved is actually useless at all.

On the ground of the black prison is the manor where the jailers who have lived here for generations have settled, so even if you dig a way up the small holes to the ground, it is useless at all.

The owner of the dry bones obviously didn't know this, so he wasted all his strength and built such a useless climbing trail.

After figuring this out, it is actually useless, there are still a bunch of problems in front of Lie Zhenbei and others.

Who is the owner of the dry bones, how did he end up here, and why is there a pile of small stone chiseling tools...... And so on, and so on, and there is still no way to solve it.

However, these questions are obviously not important, for Lie Zhenbei and others, the only important thing is how to use that pile of small hammers, small axes, and small chisels to create a way out for themselves.

As a result, these uncles and aunts with extraordinary identities became secret stone chisels in this dark prison.

The escape route they chose was carved downstream from the downstream where the stone platform was located, all the way upstream.

The reason why it is so chiseled is very simple, since the owner of the dry bones is drifted from the upstream, then there must be a ...... upstream , an exit to the ground!

This is an obvious thing, because the owner of the dry bones, he can't swim up from below, can he?

Therefore, for nearly a few months, these people competed with the stone wall, and finally built a very simple ...... The climbing trail to the first waterfall comes out.

Does it work, apparently it doesn't work any!

After listening to Wukong's story, all of them figured out all the mysteries, and they all understood that the escape path they had great hopes for was useless at all.

"Alas...... , in vain with such a lot of effort, it turns out that ...... It's all useless. After saying it in frustration, Gu Ningqing lowered her head sadly.

The owner of the dry bones is obviously the craftsman who once built the prince's underground palace, why did he end up on the stone platform, and how did those tools come from, in fact, you can know it if you think about it.

The passage that Wukong dropped is, of course, not only for dealing with household waste, but also for another function...... , that is, to dispose of corpses.

In order to keep it a secret, after the construction of the prince's underground palace, all the craftsmen who participated in the construction must be disposed of.

It doesn't matter why the owner of the dry bones didn't die at that time, as long as you know that he came down from that passage, and with the existing conditions, it is impossible to reach the exit of the passage directly above the canyon...... , in fact, it is already possible.

"Forget it, listen to what the adults say, if you don't submit to that bastard girl, it is estimated that in a few days, we will be released. Anyway, there is food and drink here, so let's ....... Without waiting for Lie Zhenbei to finish with a wry smile, Wukong directly interrupted him to continue.

"Don't wait, just climb up this stone wall and tell the people above about my situation. They must be ......!" Without waiting for Wukong to finish speaking confidently, Gu Ningqing said with a wry smile: "It's useless, the climbing trail is only more than forty meters high, and it is nearly fifty meters away from the stone house at the top." And...... The jailers above are all deaf and mute. They are...... , I can't hear it at all. ”

As soon as he heard this, Wukong was directly stupid on the spot, and after a while, he was extremely unwilling and whispered to himself: "Am I ...... , it can only be relied on luck...... Are you waiting......?"
