Luo Fatzi and the three of them also followed Wu Ze and touched it, when Luo Fatzi saw the closed stone door in front of him, he was also stunned, there is no gap in this stone door, how to break it now?

"Let's look around for any mechanism or something." Wu Ze frowned and said.

Wu Ze walked to the stone gate, only to see that there were some obscure rune patterns carved on the stone door, and he couldn't understand what these meant.

Wu Ze knocked on the stone door with his hand, it felt very thick, it was carved from a huge stone, and it might be really difficult to break through the door by force.

"Wu Ze, look, there is a groove here, could it be related to this stone gate?" Just as Wu Ze was inspecting the stone gate, Jiang Yan shouted beside him.

Wu Ze turned around and walked towards Jiang Yan's side.

The groove in Jiang Yan's mouth is on the wall on the right side of the corridor about one meter away from the stone gate, this groove is only about the size of a palm, and under this groove, there is a portrait carved, and the face of the whole portrait is vacant, and the vacant part is this groove.

Wu Ze glanced left and right at this groove, but he didn't find anything strange about this groove, but he always felt a little strange when he looked at the faceless figure under the groove.

Is this statue missing a face? The face of a portrait? Wu Ze always felt that he had found a portrait of the face somewhere, but now his head was a mess, and he had no clue at all.

"Think about it, where do we see a portrait of a face? I always feel like I've seen a portrait face about the size of this groove, do you have any impressions? Wu Ze pointed to the groove on the wall.

"Portrait face? Statue of a human face? Hey, didn't we find a wooden carved human face in that sand pile before? Could the wood carved human face be related to the face of this figure? After Jiang Yan muttered a few words, her eyes suddenly lit up, and then she said the question in her heart.

"Ha, yes, how did we forget that wooden statue? I looked at this groove, and it was about the size of the wooden carving, where was the wooden carving? Hurry up and take it out and see if it fits. Luo Fatzi said excitedly.

"Well, that makes sense, Yan'er, I remember that the fast wood carved human face ended up in your hands, you look for it, where did you put it?" Wu Ze was reminded by them, and finally remembered this stubble, and hurriedly urged Jiang Yan.

Jiang Yan was stunned, where exactly did she put that thing, she couldn't remember it a little, was it in her bag or pocket? Or was she just put in the car? Jiang Yan herself was a little confused.

So she put down the backpack behind her, squatted down and searched for a while, and finally found this fast wood carved human face in a pocket of the backpack.

Jiang Yan wiped a handful of sweat on her forehead before handing the fast wood carved human face to Wu Ze, fortunately this thing was put in her backpack, if it was put in the car, she would have to go back to the ground to find it.

Wu Ze took this woodcarved human face and compared it to the groove on the wall, the size of this woodcarved human face was just the same as the size of the groove, quite matching.

Wu Ze was a little excited in his heart, it seems that this thing is worthy of here, he pressed the human face in his hand directly into the groove, only to hear the "click", this wood carved human face was tightly inlaid on this wall, as if it was originally grown here, the statue on the wall was immediately put together completely, and a statue with a head and face was completely presented in front of everyone.

The next moment, something magical happened, only a "boom" sound was heard, and a crack was cracked in the wall of this corridor, and then the gap in the wall opened wider and wider, and after a while, a door had opened on this wall.

Wu Ze and the four of them were a little stunned, the wood carved human face was really the key to this secret room, but the problem was that it was the wall that was opened, not the stone door, could it be that this secret room was behind the wall, and the stone door was just used to confuse people? They were all a little confused.

Wu Ze thought about it for a while, and felt that it was difficult to figure it out, so he simply didn't think about it.

"Damn, this ancient man is a real thief, fortunately we accidentally got this wood carved human face, otherwise, we spent all our energy on breaking the door, and when we broke the stone door, we found that there was no secret room behind, so it is estimated that a few people will go crazy." Luo Fatzi looked happy.

"Haha, that's right, if someone spent a lot of trouble to break this stone gate, and then found that there was no way back, then it would be really impossible to go crazy." Jiang Yan echoed with a smile.

Wu Ze looked inside the cracked door, and saw that behind the wall of the corridor, there was a secret room, and from the outside, you could see that in the middle of the secret room, there was a coffin.

Wu Ze cautiously walked into the secret room, and when he entered this secret room, he found that in this secret room, in addition to the coffin placed in the middle, there were also many stacked cow skulls on the floor around this secret room.

Wu Ze counted, each stack is seven cow skulls, a total of seven seven forty-nine stacks, these cow skulls, densely placed under the walls around this secret room, white cow heads, empty bull's eyes, look a little weird.

"Brother Ze, what does this mean? Why are there so many bull heads here? Luo Fatzi asked with some puzzlement.

There were not so many cow heads in the stone room above, and they were not so neatly placed, Luo Fatzi only noticed the dried corpses hanging on the wall at that time, and didn't think about what was going on with the scattered cow heads on the ground.

Now I found a secret room here, there was not a single dried corpse in this secret room, but there were many neatly stacked cow skulls, and Luo Fat Man looked a little puzzled.

"It is said that thousands of years ago, some tribes in this land were bound to slaughter cattle when they sacrificed, in their opinion, using cattle to sacrifice the dead is the most reverent practice for the dead, which is also an important part of their religious rituals, this is stacked into seven layers of bull heads, it means that these dead people have seven layers of soul, of course, the specific situation at that time is no longer examinable, these are the guesses of later generations, whether it is true or not, no one can tell." Wu Ze explained.

"There are countless interpretations of these bull heads stacked into seven layers, and what Wu Ze said is only one of them, these interpretations are different, and various statements are supported and opposed, so up to now, there is no exact standard answer in the academic world, these statements, you just treat them as if you were listening to a story, just listen to them, don't take them seriously." Jiang Yan added with a smile.
