Come to the turtle lake, where the turtle prison is located.

Surrounded by mountains, there is a lake fed by the eastern mountains, which is the only narrow outlet at the pass.

There are many turtles in the lake, so it is called turtle lake.

And the turtle prison is in the northeast of the lake, close to the pass, that is, the outlet of the lake.

There is no road here, you need to climb over the mountains infested by fierce beasts, if you are a little careless, or you are not familiar with this place, you will be trapped in the mountains, and the masters above the great monk may get out of the mountains with the ability to come and go, but the ordinary monks, lost in the mountains, that is nine deaths.

This is because the eastern mountains are so dense and forested that each peak is about the same shape, and you can't tell if you're walking on the same peak.

People who are lost in the mountains and have a slightly lower cultivation may become the rations of fierce beasts, or even food for spirit beasts.

Wan Fei chose to build a prison in Li, and he also sinned in the city.

He believed that the guilty were exiled and imprisoned in the city of sin.

Ordinary criminals are in the city, they can go to the mine every day to mine to atone for their sins, reach a certain degree of contribution, and may be exempted from crime and go home, but this sin city has not been built for a long time, and no criminal has been put back for the time being.

And those criminals who deserve to die, but are not executed, are generally people with high cultivation, they are imprisoned in cultivation, forced to do the work of ore processing, and the main reason why they did not die is sparring, they were imprisoned in the turtle prison, used up to take it out, used up to send it back, since the establishment of the crime city and the turtle prison, there are tens of thousands of people who have been exiled to the crime city and imprisoned in the turtle prison, and now I am afraid that there are not even 10,000 people.

Wan Fei formed a guard team, about 400 people, all of whom were selected from slaves and had cultivation talents, and sent them here for training, Wan Huo was one of the leaders, and he was recently mixed with the Grand Commander.

This is also because of his own efforts, and his cultivation is high and his father has been following Wan Fei for a long time and gaining Wan Fei's trust.

Wanho was a regular visitor here, transporting supplies, escorting criminals, transporting slave guards for training, and so on.

Familiar with the road to get here.

Before entering the city again, Wanhuo gave a detailed description of the situation here.

Wan Huo spoke in detail, and Zhang Xian listened carefully to keep it in mind.

This is a small stone town, with a huge stone masonry wall of more than ten zhang high on three sides, and a cliff on one side.

There is no gate, and access is through an abandoned mine.

The mine cave is more than a mile long, and there are two animal oil lamps on the two walls every thirty or so steps.

This entrance is unguarded, and the beast oil lamp will be lit when you walk in, and it will be extinguished when you walk through, this is the masterpiece of the master of the mechanism, Peng Ze.

Peng Ze was once a disciple of the Boat King, but later disappeared, but he didn't expect to be caught here by Wan Fei.

This entrance to the mine mechanism came from him.

Because Wan Huo knew the control of the mechanism, he walked all the way to the gate of the Sin City without being attacked by the trap of the mechanism.

The person who collected the door knew Wan Huo, opened the three-foot-thick Si Gate, and let them into the city.

Zhang Xian observed it and found that the stone material of this stone gate was not ordinary, it should be iron ore.

With his cultivation, it was not easy to smash the stone gate as soon as possible.

The most terrible thing is that there are crossbow arrows on both sides of this stone gate, and when you attack the stone gate, you will touch the mechanism, and dozens of crossbow arrows will shoot you into a hedgehog in an instant.

Unless you're a half-step legend or a legendary realm powerhouse
