Sun Zhongyuan walked around and looked around, the green bricks on the four walls were all built to the edge of the dome, and he knocked many places with his hands, all of which were real sounds.

Chen Danyang looked at the green bricks on the ground, stepped on them while watching, and finally pried open a piece of the green bricks on the ground, and found that there were mountains and rocks below, which were very smooth, and there was no soil pad.

When he was irritable, Sun Zhongyuan lit a cigarette, and as soon as he took a puff, Chen Danyang shouted, ", there isn't much oxygen, you still smoke!"

"That's it!" Sun Zhongyuan sucked hard, but then extinguished.

Kuroko and Dajun stepped forward, and Dajun said, "If you don't find any breakthroughs, sit down and talk!"

Even if you discuss countermeasures, you have to save effort and energy, so the four of them sat down.

"The only place to ventilate this burial chamber is the stone door. When the stone door is closed, no matter how tight it is, there are gaps, and the outside is blocked with boulders, and the tomb road collapses, and it can always be a little breathless. If there is no other way, we move less, save air, and support until dawn, in case someone outside comes and sees that the hillside has collapsed, we still have the possibility of being dug out. The army said.

"It's too unlikely. Sun Zhongyuan shook his head, "I have been to this valley once before. For there were no trees, and there was little grass, and no one came to herd the sheep. Usually you don't see a human figure at all. And as you can see, the soundproofing of the valley seems to be very good, the huge stone balls vibrate, and the village did not react at all. ”

There was a moment of silence.

I don't know when it started, Chen Danyang stared at the Nine Palace Flying Star in the dome.

Sun Zhongyuan, Dajun, and Kuroko didn't have any ideas for a while, and they also looked at it. However, when they looked at it, it was just nine balls protruding, seven large and two small.

At this time, they all felt a little unpleasant breathing.

There are two theories about the nine stars, the first is the sun, the moon and the seven planets, and the second is the Big Dipper plus the two stars on the left and right. Obviously, the Nine Palace Flying Stars in this dome are the second type. ”

Chen Danyang muttered to himself. The three of them estimated that Chen Danyang was contemplating something, which might be related to whether they could find clues to get out, so they all listened quietly without interrupting.

"There are nine stars in the sky and nine houses in the earth. If it is set up with the feng shui of the barberry, the woody earth qi here becomes the fire earth qi. The Nine Palaces contain the five elements of the eight trigrams, among the five elements, the Zhen hexagram, the Xun hexagram, belong to the wood, the separation hexagram belongs to the fire, and the middle palace has no hexagram, that is, there is no five element attributes······"

Chen Danyang said, stood up, "The position of the coffin should be the middle palace." ”

Sun Zhongyuan, Dajun, and Heizi seemed to understand whether they understood or not, but they couldn't help but stand up as well.

"Is there any chalk?" Chen Danyang suddenly turned his head and asked.

"Yes!" Kuroko pulled out a stubby piece of chalk from her bag. This tool is always available, and sometimes when you go to the tomb, you need to mark it on the wall, etc.

Chen Danyang surrounded the coffin and drew a nine-square grid on the ground. And the location of the middle palace is naturally the coffin. The remaining eight squares are surrounded by all sides.

In the face of this nine-square grid, Chen Danyang marked the gossip symbol on it, and at the same time, on the edge of the nine-square grid, the central five-star map that the Xuanyuan star map used to display was also drawn.

"Nine is the largest number, five is the central number, the so-called ninety-five supreme, that's how it came about. Chen Danyang looked at them, "This cave, according to various signs, should have a natural foundation, because it was found in the mountain behind the best place for feng shui, and it was expanded, repaired, and transformed. ”

"If you want to echo the feng shui setting of barberry, heaven and earth echo, in addition to the 'time of day', there must also be 'location'. When the sky is in time, the handle of the Big Dipper in the dome points to the southeast, which is the turn of spring and summer, and the mystery in this is not bothered for the time being;

The other three didn't fully understand, but they vaguely felt that there was a breakthrough about to happen! Kuroko said anxiously, "Let's get to the point! This breath is already a little uncomfortable!"

A smile appeared on Chen Danyang's face, "Wood makes fire, it is the state of earth qi change, this dome nine stars, corresponding to the nine palaces on the ground! The middle palace is empty, so Cao Cao dares to set up a coffin, this position is the unchanged position! And the other eight palaces, the earthquake position, Xun position is wood, and the departure position is fire, and here the double wood becomes fire!"

As he spoke, Chen Danyang drew a straight line leading to the departure from the earthquake position and the Xun position in the palace grid on the ground.

There is an intersection in the middle of these two lines, and Chen Danyang extends from this intersection point to the out-of-position and draws an arrow!

"In this direction, there must be a natural exit! Otherwise, the Nine Palaces Flying Star Feng Shui setting here cannot echo the central setting of the barberry!" Chen Danyang said, threw away the chalk with a snap, followed the direction of the arrow, and walked to the side of the blue brick tomb, "Do it!"

This location is roughly the left side of the inner chamber.

At this moment, Sun Zhongyuan understood! Originally, there should have been a natural passage in this cave! This passage is also the key to the feng shui setting of the Nine Palaces, echoing the barberry wind! And Cao Cao did not dare to move this passage in vain, otherwise the feng shui setting would be broken!

Dajun and Kuroko immediately found the tools and assigned them to Sun Zhongyuan and Chen Danyang.

For four strong people, it is not difficult to tear down the brick wall, and besides, the army of sunspots is still an expert. Soon, the blue brick wall was torn down, and a piece about a meter wide was removed.

What was revealed was not a mountain, but a white plaster!

Obviously, this can't be something native to the cave, but something that was reinforced later!

The plaster is thick and deep. Eventually, the plaster they dug up formed two large piles in the burial chamber. On the mountain wall, a bamboo shoot-shaped stone crack that extends inward has been cleared!

The stone crack is one and a half meters high, the widest bottom, half a meter, and the middle, more than a foot.

As soon as the stone crack opened, the breathing suddenly became much smoother, and the whole burial chamber was much cooler!

Chen Danyang was relatively thin, he picked up the flashlight, lowered his body and got in.

A minute later, Chen Danyang drilled back again, "It's more tortuous inside, but it's getting wider and wider, and you see!"

Chen Danyang's fingers showed a touch of wetness, "We have analyzed before, the excellent place of feng shui is backed by the mountain, near the mountain, there are likely to be underground karst caves and underground rivers, I estimate that this stone crack can be connected!"

Sun Zhongyuan nodded, "The reason why Cao Cao can't block this stone crack can only be disguised, and not daring to destroy the feng shui setting is the key, but in fact, he can't block it, because it is connected to a large underground space." ”

The army and Kuroko high-fived each other. At the beginning, he avoided the stone ball, thanks to Sun Zhongyuan's meticulousness, and after being trapped, he found out this line of life, thanks to Chen Danyang's profound research on occult arts. The two of them, veteran tomb robbers, were dwarfed by each other.

At this time, Sun Zhongyuan and Chen Danyang were staring at the set of catalpa coffins again.
