"Pu, pu" sound, Chu Xunyu and the other two finally came out of the damn copper door. The three of them held the copper door with their hands and directly carried it to the ground, falling into a pile. Chu Xunyu got up and blew the fire breaks. The three of them looked around and found that this was a small square room, not very big, with leftover skeleton valleys everywhere. It seemed that it was the snake's nest. It could lick open the copper door and rested here every time after preying. Mu Yuan held the snake head in his hand and asked, "How could this demon snake grow a human head?"

"Let me see." Chu Xunyu was also curious. He took it and flipped it around for a while. He saw the trick, threw it on the ground casually, and said angrily, "Fake it, we were all scared by the critical situation just now. This is just a giant python fed by the sect. Although there are some tricks, it is not that scary. As for the snake head, it was stretched out with the old woman's human skin."

"Then this old woman's face is big enough." Mu Yuan kicked, "It can actually cover such a big python head."

"It's not a single person." Chu Xunyu shook his head, "When you look closely, you will find that the surface flesh was pieced together by several people, otherwise where would you go to find such a big-faced old woman."

Wangchen didn't forget to look back at the flashing copper door just now, pointing to the back of the door and saying, "The back is pear blossom copper, no wonder it takes to use saliva to open it."

Chu Xunyu shook his head helplessly: "This 'pear blossom copper' comes from a dry place in the north. The copper rust produced is swelling when dry and shrinks when water is encountered. It is extremely tough. No wonder it cannot be stabbed with a sword, but you can even open this door even if you bring a bowl of clear water. However, we didn't expect to meet it in the southern border. It seems that it is no joke that the ancient Dian Kingdom once had a very brilliant bronze civilization. In order to create a strange atmosphere, these ancient Dian Kingdom masters have taken great pains to make up, and even these bluffing methods have been used."

"It turns out that they are all charlatans who run around the world." Mu Yuan breathed a sigh of relief. "We were really stunned. Let's see where we go next and turn this place upside down before talking about it."

The ground was filled with mountains of skeleton valleys. The three of them stepped on them and were very inconvenient. The walls were covered with spider webs. Chu Xunyu used the tip of his sword to open them and check them one by one. Wangchen touched one by one with his hand and said, "Here."

When I gathered over and saw that this place was originally an entrance, but it was sealed with bricks, leaving only a contour on the wall, carved with some ancient Miao texts, Mu Yuan sighed, "We can't understand anything we say."

Chu Xunyu narrowed his eyes and looked for a while, and replied, "What he said is: Be careful when entering this door, sins will turn into dust."

"Okay, you." Mu Yuan and Wangchen looked at him in surprise, "When did you learn to know this kind of text?"

"Who said I know the ancient Miao text?" Chu Xunyu pointed at the bottom of his hand, "There is a line of small characters here, which are small seal scripts of our Han people, and I just read them."

The two of them rolled their eyes in anger. Chu Xunyu stretched out his head and sniffed the wall, telling the two: "The technique is very clever. This wall is made of iron juice, mixed with many other things. There are at least twenty kinds of herbs that I can tell, and there are also talismans, formations, pangolin scales, rooster blood, etc., to ward off evil spirits, insects, and brute force damage. This material can prevent most foreign invasion methods. Even if an invisible ghost is called in, it cannot penetrate it." After saying that, he poked it with the Jianqing Sword. After only one inch, he could never penetrate it. This is not because the Jianqing Sword is not sharp enough, nor because the wall is too hard, but because the material is extremely tough. The Jianqing Sword seems to be poked on a ball of sticky mud inside the wall, and the bonded sword blade cannot enter or come out.

Mu Yuan smashed the wall with his fist: "After you say that, this is simply a wall of iron and iron, and it is not invaded by water and fire. How can I break it?"

"Hmph..." Chu Xunyu sneered, "Just just use the Buddha's light to burn it. Although this wall is powerful, there is one key point, that is, there are many corpses mixed with corpses in it. You can burn it with the Buddha's light first, and then burn it with fire."

"Corpse worm?" Mu Yuan asked strangely, "Can this thing be used to build walls?"

"Yes." Chu Xunyu replied, "Corpse worms are born in corpses and belong to the Yin. Use it to build walls to ward off fire and drive away water. They are used in the tombs of princes and nobles of the Song and Yuan dynasties. The secret method is a royal secret, which is difficult for ordinary people to know. From this, it can be seen that the owner here is extraordinary. You first use Buddha light to burn the corpse worms in the wall to powder, so that you can roast them with fire, otherwise it will not be ignited."

"Welcome to meet Buddhist disciples to dig the ground!" Mu Yuan laughed and laughed, holding the wall with both hands, releasing the Buddha's light again. When Mu Yuan stopped, Chu Xunyu took out some old clothes, lit them, and placed them under the corner of the wall to burn. After the fire was extinguished, he used the brute force of the martial artist to use the remnant long sword to pry it down the burning place bit by bit. After a cup of tea, he took out a small hole the size of a fist. The three of them stretched their heads and looked at it. There was a black air inside, but there seemed to be a downward staircase, empty and quiet.

The three of them opened the hole with their hands, and the fire was loosened a lot. They made a hole with half a person and bent down and crawled in. This was a black stone staircase that had been covered with dust for many years. There were some simple torches on the walls, which could be turned into powder with just one touch with their hands. Chu Xunyu thought about it, and turned around and picked up a dead leg bone, tied it into a simple torch with old clothes. After igniting it, the three of them understood that the staircase was winding down. Mu Yuan asked, "What will be below?"

"I don't know." Chu Xunyu smiled relaxedly, "Anyway, it's not that the host is ready to entertain us."

"Let's go." Wangchen was also happy, shrugged his shoulders and took the lead and walked out.

Unexpectedly, the stairs were not long. Not long after going down, I saw a flash of wooden doors, which could be pushed open easily. After entering, I found that there were several small rooms on both sides, but the rooms were already empty and no one had come for many years. Among them were the already broken bed boards. Mu Yuanqi asked: "What's the solution? Did you open an inn in the mountains?"

"No, it's a cell." Chu Xunyu replied quietly, holding the torch to a prison door. "It's all fences made of copper strips. It seems that many prisoners have been detained here for some reasons."

"The lock is open." Wangchen stood by the door and picked up a rusty copper lock, "It was opened by someone with a key. It seems that there is no accident."

"Then the words on the door we just came in outside..." Mu Yuan thought for a while, "Can this be understood as this is the Heavenly Prison of the Gu Dian Kingdom back then? It is specifically detained prisoners?"

"Thinking like this is OK." Chu Xunyu nodded, "What does sin mean to turn into dust? Maybe it's because there are many traitors and evil people from southern Xinjiang here."

The range of torches illuminated was very small. The three of them stood in the dark and faint corridor of the cell. Even a needle fell to the ground could be heard. It was hard to imagine what had happened here. Suddenly, a sound of iron chains disturbed everyone. Chu Xunyu said angrily: "Bajie, stop making trouble!

"It's not me." Mu Yuan raised his hands with a grievance, "Where should I go to find the chain?"

As soon as these words were spoken, the three of them suddenly changed their expressions and they all looked at the end of the corridor, where it was pitch black...
