Liu Chengfeng took Li Zhang and them along the excavated mountain road all the way forward, the mountain road became narrower and narrower, and in the end they could only go side by side, but Li Zhang was not worried about safety, because the officers and soldiers he brought had blocked the roads up and down the mountain, and there were wild dogs in front of them escorting Liu Chengfeng to explore the way, and he was not afraid of any tricks played by the other party at all.

When the excavated mountain road came to an end, Liu Chengfeng actually took them on a path full of wild grass, and there was no trace of the mountain wall next to it, the road was full of gravel, very rugged, which made Li Zhang also frown, and asked loudly at the moment: "Liu Chengfeng, you don't want to play any tricks, there will be no road any further!" ”

"Just ahead, past that tiger-shaped boulder!" Liu Chengfeng wiped his sweat at this time and pointed to a huge stone road in the distance, this stone has a strange shape, and it looks like a crouching tiger at first glance.

"Okay, the wild dog will take him up and have a look!" Li Zhang looked at the boulder in the distance, and then commanded the wild dog.

I saw the wild dog nodded, suddenly reached out and grabbed Liu Chengfeng's collar, carried him a few flies to the boulder in front of him, and bypassed the boulder, after a while, I saw the wild dog poke his head out from behind the boulder and shouted: "Big brother, there is a strange cave here!" ”

Hearing the wild dog's words, Li Zhang also immediately sped up, and soon bypassed the boulder to come here, only to see the wild dog and Liu Chengfeng standing behind the boulder, in front of them was a dense bush, the wild dog pulled up the bush at this time, revealing a round hole in the ground, it looked like a well, and because there were shrubs and boulders before, if it wasn't for Liu Chengfeng to lead the way, I'm afraid it would be difficult to find even if it was walked by.

"This hole ......" Li Zhang walked a few steps forward at this time, and squatted down in front of the cave entrance, because he found that this cave entrance was quite strange, mainly because it was too round, as if it had been drawn on the ground with a compass.

Li Zhang came to the cave to observe carefully, only to see that the hole was straight up and down, and the bottom could not be seen at a glance, and the hole was not very round, and then Li Zhang reached out and touched the stone wall of the cave, and his face also changed, because he found that the stone wall was smooth and abnormal, and it did not look like it was formed naturally, nor did it look like it was artificially excavated, because the excavated stone wall could not be so smooth at all, unless it was polished a little bit after excavation.

"Bring the torches!" Li Zhang immediately instructed the entourage behind him, and someone immediately handed over the prepared torches, which was also requested by Liu Chengfeng before, because he said that the evidence was in a stone cave, but Li Zhang didn't expect that the evidence had not yet been seen, and this stone cave alone was so peculiar.

At that moment, Li Zhang stretched the torch into the hole, and he couldn't see anything in the darkness below, but his face changed again, because he saw that the stone wall was extremely smooth, and even reflected like a mirror, and Li Zhang also lay on the ground at this time and carefully observed the stone wall, and found that the stone wall was no longer a rough stone, but a glass-like thing on the surface, which was why it was so smooth.

Li Zhang stretched out his hand and touched the stone wall again, he felt that this thing was somewhat familiar, it seemed to be a glass-like crystal obtained after the stone melted and cooled, he remembered that he had been to the volcano in his previous life, and after the magma emitted by the volcano cooled, some formed a glass-like thing, obsidian is a kind of volcanic glass, and the stone wall in front of him is similar to the volcanic glass he has seen.

"It's not a volcano, it's impossible to erupt magma, how can there be volcanic glass?" Li Zhang frowned at this time and said to himself, not only is this stone wall strange, but the entire cave entrance is also too round, it looks like it was cut out of a circle by some tool, it is incredible.

"Li Yushi, the evidence is in this cave, and this stone cave is also very strange, until now I don't know if it is natural or man-made?" At this time, Liu Chengfeng suddenly spoke, he saw Li Zhang studying this cave entrance so seriously, which made him also show a relaxed expression, Li Zhang was interested in the cave entrance, and the things in the cave would definitely make him more interested.

Li Zhang also stood up at this time, then glanced at Liu Chengfeng and asked, "How did you find this hole?" ”

"Don't hide it from Li Yushi, this matter is actually a coincidence, the last time the hat demon was troubled, many people here in Luoyang have seen the hat demon, and we have also collected a lot of rumors related to the hat demon, among which there is an old Hui man who used to be a stonemason here in Longmen, according to him, he has seen more than a dozen times the hat demon appeared in Longmen, and even some hat demons fell to the side of Dongshan, he came to Dongshan to look for it out of curiosity, and found this hole, and also saw a piece of evidence left by the hat demon at the entrance of the cave." Liu Chengfeng didn't hide it, and said again very sincerely.

Li Zhang didn't suspect it when he heard this, he looked at the records of the hat demon in Luoyang Mansion before, and knew that there were indeed many witnesses to the hat demon on the Longmen side, but he didn't pay attention to it at the time, because there were too many rumors of witnessing the hat demon back then, and now that he thinks about it, it seems that the incident of the hat demon on the Longmen side is higher than in other places.

Li Zhang looked at the black hole, and then threw the torch down, and found that the hole was indeed straight down, but it was much shallower than he expected, and the torch fell to the ground about twenty meters down, and with the light of the fire that was not extinguished, Li Zhang found that there seemed to be a larger space below.

"Put the ropes!" With Li Zhang's command, someone behind put down the prepared rope, this hole is actually not very big, the diameter is about two meters, but the stone wall is extremely smooth, there is no place to climb at all, if there is no rope, it is impossible for people to climb up if they fall.

The wild dog was about to be the first to go down at this time, but Li Zhang grabbed him at this time and whispered: "Be careful, if you encounter any danger, come up immediately!" ”

Although Li Zhang believes in the strength of wild dogs, this hole is really a bit weird, and it is related to the legendary hat demon, so Li Zhang has to be careful.

After hearing this, the wild dog nodded, took out the dog's leg knife and put it in his mouth, and then went down the rope to the hole, and when he landed, he immediately held a torch and walked around the hole, and then said loudly to the top: "Big brother, there is a lot of space below, and there are many black and slimy passages around, I don't know where it leads?" ”

"Is there anything strange that proves that the Hat Demon has been here?" Li Zhang asked loudly again at the moment.

"I haven't found it yet, but there's a human skeleton underneath." The wild dog replied again.

"Human bones?" Li Zhang was stunned again when he heard this, and then looked at Liu Chengfeng next to him.

"There are indeed human bones underneath, but there are not many, and I suspect that someone accidentally fell into the hole over the years and died." Liu Chengfeng hurriedly explained at this time.

Li Zhang was also very curious about the situation under the cave at this time, but before he went down, he still let Liu Chengfeng go down first, lest he play any tricks on it, but Liu Chengfeng was wearing shackles at this time, and he had already opened his shackles when he went up the mountain before, and if he was allowed to go down the rope, his shackles must also be opened.

Li Zhang thought that the wild dog was below, and he didn't have to worry about Liu Chengfeng escaping, so he asked people to open his shackles, and then Liu Chengfeng went down the rope to the hole, and then Li Zhang asked some officers and soldiers to go down to help the wild dog watch Liu Chengfeng, and also help survey the terrain, and finally he went down to the cave himself.

At this time, a lot of torches had been lit in the cave, and when Li Zhang was down-to-earth, he immediately found that there was something wrong with his feet, and when he moved the soles of his feet, he found that there was a broken bone under his feet, and there were also a lot of white bones scattered on the surrounding ground, among which there were also wild beasts, which should have accidentally fallen from the ground into the cave and died.

At that moment, Li Zhang looked at the entire cave, and saw that the cave was not very big, the whole was hemispherical, and this hemispherical shape was very regular, like a huge bowl upside down on the ground, whether it was the ground or the top of the head, it was all very smooth, and the material of the stone wall seemed to be all vitrified, and around this space, there were seven or eight holes, and the black and slimy did not know where it led?

It's just that to Li Zhang's surprise, there are no other conspicuous things in the entire space except for the scattered white bones on the ground, and there is no evidence of what Liu Chengfeng said, which made him a little puzzled, and immediately asked: "Liu Chengfeng, where is the evidence you said?" ”

"Li Yushi is in a hurry, the last time we came, the evidence was placed on the ground, but then I put it away!" I saw Liu Chengfeng come out of the crowd at this time and said, just now in order to prevent him from escaping, the wild dog and others have been staring at him, because there are holes around, they are afraid that this guy will escape.

I saw Liu Chengfeng walking towards one of the holes, but he was blocked by wild dogs, which made him look at Li Zhang a little helplessly and said: "Captain Li, the evidence is inside, and the holes here are all dead ends, there is no way to escape." ”

"Let him get it!" Li Zhang immediately signaled to the wild dog.

Hearing Li Zhang's words, the wild dog let go, and then saw Liu Chengfeng holding a torch to a hole, and along the light of the torch, Li Zhang also saw that there seemed to be something on the ground in the cave, and then saw Liu Chengfeng bend down and drag out a rather heavy thing, then Li Zhang found out that it was a box, but the box was very new, which made Li Zhang immediately suspicious, but then he thought that Liu Chengfeng said that he had put away the evidence before, so this box should be used by him to hold evidence.

Thinking of this, Li Zhang also let go of his suspicions again, only to see that after Liu Chengfeng dragged the heavy box out, he seemed to be tired, and he took a breath before he said to Li Zhang: "Li Yushi, the evidence is inside, do you want me to help you open it?" ”

"Open!" Li Zhang immediately commanded, he didn't know what was in the box, and of course he didn't want to let others take risks.

For Li Zhang's carefulness, Liu Chengfeng smiled slightly, then bent down and grabbed the handle of the box, and suddenly lifted the lid of the box.
