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

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

However, the stone walls on both sides are extremely slippery and steep, and without tools, they can't climb up at all.

According to Wukong's experience, there are at least two waterfalls upstream of the underground river, which are dozens of meters high. It is unknown whether there are waterfalls downstream of the stone platform, which is a hundred meters long and twenty meters wide. After all, the downstream is pitch black and there is nothing to see.

The reason why Wukong encountered Lie Zhenbei and others underground was very simple. This 100-meter stone platform dug by the Double Cultivation Mansion was built fifty years ago!

Every day it is about morning, a square basket will be lowered at a height of a hundred meters above the stone platform, with enough food for all prisoners to eat for a day, and a full thirty candles.

The only way to leave this terrifying underground stone platform is to sit in that big basket and be pulled up from above. In addition, there is no second way for prisoners who have already taken the lock pill but have no tools.

Of course, it is OK to sneak into the big basket while delivering items every day, and then pull the chain and climb onto it secretly, but this is useless at all, because once you find that the weight is wrong, the person above will immediately sprinkle turmeric oil down.

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. The two prisoners who returned to level nine in the void were guarded by them.

Such a terrifying black prison, the Double Cultivation Mansion has built seven entirely in various cities of Youzhuo two prefectures. A century of history has proved that no prisoner has ever been able to escape from such black prisons...!

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

The reason why Western officials chose to beg them here is actually very simple. The only reason is that the environment here is considered to be the best among the eight underground black prisons!

That's right, it's just a ghost place where you don't have to wear shackles, eat and drink every day, and you can still move around without any trouble, and you won't see the light of day. That's the most comfortable black prison.

However, what the masters of the Shuangxiu Mansion never expected was that they all believed that the living environment was the best and impregnable underground prison in Chang'an, which had a major accident more than 20 years ago!

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

"Sir, after hearing what you said, I finally understand the source of those tools." After speaking in a low voice, Lie Zhenbei pointed to hundreds of stone chiseling tools in the corner.

When they were just put on the stone platform, they discovered something strange, that is, there was not only a broken bone with broken legs, but also a bunch of neatly arranged..., various small stone chiseling tools.

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

Then, they found that two rows of extremely regular rows of holes were built on the stone wall opposite the dead bones, and they kept climbing upwards. So one of them continued to climb along the hole until about forty meters high, and there was no more hole for climbing upwards.

After the man came down, everyone guessed what his identity was, and why he risked his life to dig two rows of escape holes in this black prison that he had never used before.

This person is definitely not from the Dual Cultivation Mansion, nor is he a prisoner or prisoner in the Black Prison. The reason is very obvious. The road to escape from the upwards was actually useless at all.

On the ground of the Black Prison are the manors where the prisoners who have lived here for generations have settled. Therefore, even if they follow the climbing holes and dig up a road that leads to the ground, they are useless at all.

The owner of the dry bone obviously didn't know this, so he squandered the power of the ox and tigers and built such a useless climbing trail.

It is actually useless to figure this out. There are still many problems, and they are placed in front of Lie Zhenbei and others.

Who is the owner of the dry bone, how did he get here, and why there are a bunch of small stone chiseling tools..., etc., and the problems are still completely impossible to solve.

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

So, these uncommon uncles and aunts of all kinds became secret stone chiselers in this dark prison.

The escape route they chose was to be carved from the downstream of the stone platform and it was all the way upstream.

The reason for carving like this is very simple. Since the owner of the dry bone floated upstream, there must be an exit to the ground upstream...

This is an obvious thing, because the owner of the dead bone cannot come from below, right?

Therefore, for nearly a few months, these people became more and more interested in the stone wall and finally built an extremely simple climbing trail leading to the first waterfall.

Is it useful? Obviously it's useless!

After listening to Goku's story, all of them figured out all the mysteries and understood that their escape path with great hope was useless at all.

"Oh..., it turns out that such a lot of effort is wasted, it turns out... it's all useless." After saying frustrated, Gu Ningqing lowered his head sadly.

The owner of the dry bones was obviously the craftsman who once built the Prince's Underground Palace. Why did he fall to the stone platform and how did those tools come from? Actually, you can tell by thinking about it.

Of course, the passage that Wukong fell not only can only deal with domestic garbage, but its other function... is to deal with corpses.

In order to keep the secret, after the Prince's Underground Palace was built, all the craftsmen involved in the construction must be dealt with.

The reason why the owner of the dry bone was not dead at that time was no longer important. As long as you know that he came down from that passage, it is impossible to reach that passage exit directly above the canyon... in fact, it is already possible.

"Forget it, listen to the lord's story. That bastard girl, I guess she will release us in a few days. Anyway, there is food and drink here, so we will..." Before Lie Zhenbei finished with a wry smile, Wukong interrupted him and continued.

"Don't wait. Just climb up this stone wall and tell the people above me about my situation. They will definitely...!" Before Wukong finished speaking confidently, Gu Ningqing said with a wry smile: "It's useless. The climbing trail is only more than 40 meters high, and it is nearly fifty meters away from the top stone house. Moreover..., the jailers above are all deaf and mute people. They are... and they can't hear it at all."

When he heard this, Wukong was stunned on the spot. After a while, he was extremely unwilling and whispered to himself: "Can I... just rely on my luck..., wait...?"
