According to the nature of the mechanism that affects the whole body, it is indeed very likely that a second chain of mechanisms is placed on these four stone walls.

It's just that what makes Wu Yi feel strange is that these four stone walls look like four rectangular boulders as a whole, not made of small stones, so it stands to reason that there is no way to place institutions inside the stone wall, the more Wu Yi thought about it, the more strange he felt, so he reached out and touched the wall in front of him.

With a light touch, Wu Yi immediately let out a sigh of surprise, and immediately felt that there were many shallow marks carved out of the surface of this stone wall, which were like lines of patterns, as if they were outlining some shapes.

Because the stone wall was black, these shallow marks could not be seen at all if you only looked at them with your eyes, and if you had not touched them with your own hands, you would not have been able to find them at all.

When the three of them heard this, they also hurried to the other three stone walls to touch, and sure enough, these three stone walls were the same as the situation Wu Yi said, all of them were crisscrossed with shallow marks, as if they were recording some pattern information.

The blind man touched and touched, and suddenly sighed, and wondered,

"Master Wu, this ...... This wall doesn't seem to be made of stone, you hear the voice-"

As he spoke, the blind man tapped the wolf-eye flashlight in his hand on the stone wall in front of him a few times, and there was a crisp sound of 'sonorous and sonorous' from above, not the sound of 'knocking and knocking' when hitting the stone.

Wu Yi also tapped a few times and listened, and it was the same, and he couldn't help frowning, these four things are not made of stone, what could they be? It sounded like metal, but it didn't feel metal, and then, the blind man gasped and said,

"Master Wu, the old man knows, this wall is made of stone and metal zinc mixed together, you smell it carefully, it still retains the unique pungent smell of metal zinc!"

The fat man was full of thoughts on the pagoda, anxious to get the treasure, so he had been waiting for a long time, and when he saw that the blind man mentioned what metal zinc, he immediately said impatiently,

"We're not here to make a geological report, you don't care what it's made of? Don't interrupt Xiao Wu's train of thought, let him see if there is a mechanism on this wall first! ”

A look of horror appeared on the blind man's face, obviously thinking of something, and hurriedly said,

"Fat man, don't you know, when the metal zinc encounters mercury, it will dissolve immediately, that is to say, if the mercury in the pagoda flows out, these four walls will be melted immediately, if there is really any mechanism hidden in this wall, as soon as the wall melts, they will all be triggered!"

Wu Yi didn't know anything about this kind of chemical knowledge, and when he heard the blind man say this, he was also surprised, and touched the shallow marks on the wall, and said,

"Let's figure out what is engraved on these shallow marks first, maybe it's some information about this temple, and then we can find a way to crack the mechanism inside.

If you can't crack it, you can use bombs to blow up all these walls, and even if there are mechanisms inside, they will all be blown to pieces at once! ”

After speaking, he looked at the fat man again,

"Fatty, your trick should come in handy again, I just don't know if we still have so much paper for you to burn."

The fat man was stunned for a moment, and then understood what Wu Yi was referring to, patted his chest and said,

"These walls are all black, there is no need to burn paper, I will go to the neighborhood to collect some fine ash, and I will wipe it on the wall later, and I can see it clearly!"

After speaking, he took off the mountaineering helmet on his head, and used it as a container, and collected the fine ash nearby, and within a few minutes, it was full, Wu Yi and the three of them also learned from the fat man to get a lot, and the four of them were assigned it, each responsible for a wall, and then quickly began to wipe the fine ash into the shallow marks on the wall, and the patterns and words outlined by the whitish lines gradually appeared in front of several people!

The four of them gathered together, first looked towards the east wall, the surface of the wall, many positions have been damaged and blurred, but the overall preservation is still complete, it can be vaguely seen that it is carved on a grand picture, from left to right can be divided into three parts.

Seeing the thing drawn on the first part on the far left, Wu Yi and the fat man couldn't help but shrink their pupils, only to see that the one depicted on it turned out to be the strange snake with a human face!

This strange snake is portrayed vividly, a shallow mark of ups and downs, as if it is a snake with layers of scales, it is entrenched in front of a village at this time, in the contrast of its huge size, the village is as small as a toy, its snake tail, there is also a mountain peak, making a move that wants to use this peak to smash the village in front of it.

The fat man exclaimed,

"Why is this snake so big, is this still a human-faced snake, it's just a human-faced dragon!"

Wu Yi shook his head and said,

"When the ancients depicted the things they admired in their hearts, they generally deliberately exaggerated it, perhaps this human-faced snake itself was only the size of a palm, but in order to show its power, it was painted so big."

The fat man nodded thoughtfully, and then looked at the second part in the middle, the highest part of the second part, depicting a crack in the sky, under the crack, there is a Buddha stepping on the lotus throne, is slowly falling from the sky, the Buddha is wearing a wide robe, one hand points to the huge human-faced snake, the other hand twists a string of Buddha beads, the footsteps are slightly forward, as if to prevent the human-faced snake from attacking the village with the mountain peak.

The third part of the picture depicts the scene of the battle between the human-faced snake and the Buddha, the scene is even more magnificent, everything around has become ruins, in the black smoke miasma, the face of the human-faced snake looks extremely hideous, very vicious, is spitting a long snake letter at the Buddha, and there seems to be a black poisonous mist spewing out of the mouth.

The Buddha is sitting on the lotus throne, solemn and serene, stretched out a finger, pointing at the human-faced snake, on the fingertips, but also carved many strange Buddhist symbols, on which exudes brilliance, I think it should be the kind of spell to suppress evil spirits and the like.

But what is the victory or defeat between the Buddha and the human-faced snake, it is not depicted again, and several people hurriedly turned their heads and looked at the wall on the right, the content engraved on it is connected with the content of the wall just now, and it is really about the final result.

The fat man looked at it and immediately said happily,

"Hey, this snake was quite arrogant just now, isn't it still kneeling in front of the Buddha now?"
