With the light of Sun Zhongyuan's flashlight, they saw that there were also a row of holes on the stone walls and stone roofs on both sides three or four meters ahead.

These holes are much larger than the holes in the door. It has to be the size of a football, and the interval is the same distance.

"Mechanism?" Kuroko took a breath and scolded instead, "These Tartars are really calculating, it's almost at the door, and people's vigilance has been relaxed, so they set up such a mechanism!"

The army took two steps forward, "It must be a stampede trigger underground, right? ”

Chen Danyang thought for a while, "It's not early today, I think, if it doesn't work, let's withdraw first, and come back tomorrow to study, just bring some more corresponding tools." ”

The four of them briefly discussed it and decided to withdraw first.

By the time they had disguised the hole in the valley, the light was already a little exposed.

The four of them returned to the town, had breakfast, and went to sleep.

In the evening, the four of them went to the valley together.

"This way of boiling, day and night, is about to become a night owl. Chen Danyang smiled bitterly.

"You have to take it tonight, or you'll have to do it for days in a row, and the innkeeper's curiosity will be a bad thing. Sun Zhongyuan lit a cigarette and looked out the car window, the night was dark, and the branches of the trees on the side of the road were rustling, adding a bit of cold.

This time, it was considered extremely skilled, and the four of them quickly went down to a place more than twenty meters away from the hole stone gate in the tomb.

Before, the army and Kuroko had carefully inspected the tomb passage to confirm that the place they walked through should be fine.

They each pulled out two lumps of lead and threw them at the stony ground beneath the holes in the stone wall.

I only heard the sound of Kerala, and the stony ground in that place suddenly sank!

Then, the ground collapsed!

It turns out that the stony floor here is only a thin and brittle stone slab, and if there is a little weight, it will collapse!

At the time of the collapse, in the stone cave at the top of the stone wall, slender sharp stones suddenly fell! These sharp stones, only a dozen centimeters in diameter, but one meter long, pierced directly into the stone pit after the collapse!

However, the holes on both sides did not react.

The four of them looked at each other several meters apart, and they didn't speak, but they all understood what they meant by each other: wait.

Sure enough, after waiting for about three minutes, something like oil slowly flowed out of the holes on both sides of the stone wall, and it all flowed into the stone pit.

After about ten minutes of observation, the oil-like stuff basically stopped flowing, showing a slow ticking pattern, and the four of them walked to the edge of the stone pit.

When I walked to the side, I saw that this stone pit was six or seven meters deep, and the four walls were very smooth. Even if you fall and don't die, you may be pierced to death by the sharp stones falling from the holes above, and even if you can't die, you won't be able to get up, and I'm afraid you will starve to death.

"What is this oil for?" Kuroko sniffled, "It seems to have a sweet smell!"

Sun Zhongyuan looked at the oil on the top and bottom of the stone pit, "I don't know what kind of special oil it can still flow out after so many years." However, there should be honey or sugar added to it!"

Chen Danyang shouted, "I see! If the person who falls down cannot be pierced to death by a sharp stone, then this oil can make the stone pit more slippery and more difficult to climb up! At the same time, if honey is added, it will attract ants and all kinds of insects! Let the people below be attacked!"

"It's so vicious!" Kuroko spouted.

Sun Zhongyuan smiled bitterly, "It's not that people are vicious, it's that we want to dig people's 'ancestral graves', won't there be nothing wrong if we don't come in?"

The army took a hard puff of his cigarette, "Don't discuss this, how can this pass!"

It turns out that this stone pit is not only deep, but also the width of the collapse is not small, it has to be more than five meters, and it is too difficult to jump over! Even if the long jump champion comes to run and jump, the height of this top is too low, and it is difficult to jump.

And isn't this also climbing a mountain and a tree, and the rope with a hook is thrown flat, and nothing can be hung up.

Sun Zhongyuan smiled, took two steps back, and then ran the internal force, and after a forward rush, he fell slightly to the edge of the pit, and then kicked the edge of the pit with his foot, and suddenly flew flat to the opposite side and fell down.

"Throw the rope here, I'll drag you all over!" Sun Zhongyuan said after standing still.

Chen Danyang was the first to come, fixed around his waist, and tightly grasped the rope with both hands; as soon as Sun Zhongyuan mentioned a belt, Chen Danyang flew over, and when he landed, Sun Zhongyuan used Tiangang's thirty-six hands and took it easily.

As concocted, the army and sunspots also came.

"Hard work, you'll have to come again when you go back!" Kuroko said with a smile.

"Don't say so much, hurry up. Pay attention to check if there is any abnormality. Sun Zhongyuan replied.

The four of them carefully checked while moving forward cautiously, and there was nothing abnormal, and finally walked to the stone gate.

As soon as the flashlight flashed, the four of them saw clearly that the hole the size of a ping-pong ball on the stone gate formed a vermilion bird pattern.

However, the stone door seems to be embedded in the stone wall, and it seems that there is no place to open it.

Chen Danyang carefully observed this Vermilion Bird pattern.

The hole in the stone door was not pierced, but only a dozen centimeters were entered.

At this depth, the stone gate was not penetrated, which shows that the thickness of the stone gate is not small.

"Wouldn't it be the core of this Four Elephants Divine Qi Array, there is no way in, right? After it is completed, it will be completely sealed, and this Vermilion Bird Gate is actually a big stone?" the army said.

"Impossible!" Chen Danyang shook his head, "If the Four Elephants Divine Qi Array is completely sealed, then what can we talk about echoing heaven and earth? And these four elephant doors should be able to be opened, otherwise it will be useless!"

Sun Zhongyuan took out a cigarette, sent it around, and looked at the time again, "It's still early, let's take a look at it together." ”

Chen Danyang looked at this Vermilion Bird pattern and was fascinated.

The Suzaku pattern composed of this hole is not an ordinary bird, but is arranged according to the seven stars of the Suzaku area, and each star uses a different number of stars.

In the end, Chen Danyang actually stretched out his fingers and counted them one by one.

Finally, his eyes lit up, and he pointed to a hole and said, "There are seven Nakshatras in the Vermilion Bird Star Zone, and the number of stars used for each Nakshatra varies. You see, the other constellations are five or six at most, two or three at the least, but only the Ghost Golden Goat is one!"

The Ghost Golden Sheep is one of the Seven Nights of Suzaku Bird.

Sun Zhongyuan immediately said, "This formation, with the golden qi as the respect, only the ghost golden sheep has set up one, could it be that this hole is the weakest?"

"It's not just weak, I guess, this stone hole should have been passed, but it was blocked later!" Chen Danyang said, picked up a crossbow arrow, and pierced the hole.
