Zhang Ping took the compass from Wumei's trembling hands, walked forward a few steps, stopped again, walked a few more steps to the left, and stopped again.

Wang Yan looked around and said, "It seems that there is a magnet in the hall." He ordered the guards to bring an iron key, tie it with a rope, carry it on his own, and also walk around and stop in the hall.

The iron key is not obviously adsorbed, and it only feels a little absorbing on some grounds, walls, and the black pool edges of the Yin and Yang Pools.

The compass pointer in Zhang Ping's hand trembled and swayed in every direction and could not stop.

Wang Yan chuckled: "Interesting, it seems that the magnet must be hidden behind the stone wall, polished into powder and applied in the gap. What is the purpose of this arrangement?"

Lan Jue said: "I heard that some mechanisms must use magnets, the stone doors in the hall are opened and closed, and these two thousand-pound stone pillars are raised flat on the ground. The mechanisms inside them rotate, or have the power of magnets."

Zhang Ping walked to the side of the wall: "The officials thought that in addition to the possible failure of the agency, it was still for the purpose of deterrence."

Wang Yan said, "Yes, most of the tomb robbers have compass. The tools for digging soil and stones are mostly iron tools. The key body is small and you don't realize anything. If a larger iron guy is held in his hand and is attracted by magnetic force, he will feel heavier or something unusual. In addition, the compass needle jumps and feels guilty, he will feel like hell."

Wumei, who was chanting scriptures and drawing talismans in the void, paused a little awkwardly when he heard this.

"The Master Wuliang Heavenly Lord. You all practice Confucianism and often hold the theory of no ghosts. But I think that the underworld has many spirits and must be respected."

Wang Yan briefly said: "I have never seen a ghost in our department. It has it or not. I am the official, but I have to check the haunted case." He looked at Zhang Ping again, "What, do you have any other ideas?"

Zhang Ping lowered his head to the dome: "Report to the master, I think that if you look down, you can make a more accurate judgment."

Wang Yan's pupils shrank: "What did you say?"

The guards and Wumei also looked at Zhang Ping together. Lan Jue glanced around: "Oh? There is another hall, but the headquarters did not find it."

Wang Yan stared at Zhang Ping: "Previously, our department led people to check whether there were other agencies. We have not found the secret door leading to another place. Have you found it?"

Zhang Ping bowed to Wang Yan: "The official wants the two guards to retreat outside the door first, please let the Lord allow it."

Wang Yan nodded and pointed two guards nearby and retreated outside the stone gate.

Zhang Ping gave another gift, walked straight to the Qian Gua wall, raised his hand and pushed the lotus support under the brazier of the Qian Gua lamp post. The support actually turned slowly. Zhang Ping pushed it six times, and then pressed it on the hexagram on the ground a few times. The ground suddenly shook, the stone gate closed, and some fragments fell from the dome.

Zhang Ping walked to the Kan hexagram again, held the lamp eight times, and pressed it on the hexagram on the ground again. The ground began to tremble again, and the black body of the Yin-Yang Pool slowly sank, revealing the top of a ladder.

Several guards rushed to the entrance of the cave, lowered a lantern into the cave, and then asked Wang Yan to go in first.

Several other yamen runners approached other pillars, and Zhang Ping said, "These should not be used." He also walked to the nearby Xun Gua, pushed the light support, and pressed the hexagram. The walls of the stone hall shook a few times, and two pieces of slag fell, and nothing else happened.

Zhang Ping stood up, Wang Yan stood by the cave, looking at him with his hands behind his back: "Li Kan is opposite, Li Gua rises, and Kan Gua falls. When Li Gua opens, the Kun position stone gate opens, so the Qian hexagram can only be activated by closing the stone gate. It is because the headquarters did not think about these carefully enough, and let you go first. I have also thought that the lamp post is also a step to turn the mechanism, but how do you know how many times should the lamp support turn?"

Lan Jue also looked at Zhang Ping. When Zhang Ping turned the light support just now, he also paid attention to counting the number of circles, six and eight...

Zhang Ping lowered his eyelids: "When I replied to the master, the official found that the location in the hall might be wrong, so he calculated the location he should have."

Lan Jue said: "You asked Wumei to take the compass to confirm this? The number of times you turned the lamp holder at the Qian hexagram and Kan hexagram did not match the hexagram."

In the innate Bagua, the direction is the south, and the corresponding number is one. In the acquired Bagua, the direction is the northwest, and the corresponding number is six.

Zhang Ping turned six times at the Qian Gua, which was the same number corresponding to the acquired Bagua.

But the number eight is the north direction in the innate Bagua, and the north direction in the acquired Bagua, and the north direction in the acquired Bagua has nothing to do with the Kan hexagram. The direction in the Kan hexagram is east in the innate hexagram, corresponding to the number six, the direction in the acquired hexagram is north, and corresponding to the number one.

The hexagrams engraved on the ground of the stone palace are the innate Eight Trigrams. In this way, there is only one possibility—

"Can the hexagrams engraved in the hall are not the correct direction? The innate hexagram, six is ​​Kan. The mechanism of Qian hexagram you just pressed is actually Kan. And the mechanism of Kan hexagram you pressed..."

Zhang Ping took the lantern from the guards and illuminated the Kan hexagram: "Sir, please look."

Lan Jue walked closer and sure enough, although the stone bricks were painted into the Kan Gua, the concave shape was Kun!

Wumei bit his finger: "I am really confused. Aping, this is not dry or tampered, it is..."

Zhang Ping said: "In fact, it is just confusing the direction. The ground and walls of this stone hall were originally going to be turned."

Wumei gasped: "Can you turn?"

Zhang Ping looked at the dome: "But I can't turn anymore at this time, and I've been stuck in the mechanism."

Wumei was also staring at the dome, but he was still very dizzy. Zhang Ping took out an egg from his pocket, turned his head upwards, and slowly turned it.

"If this upper half was a stone hall, the original mechanism would move, its stone wall would be able to rotate like this."

Zhang Ping knocked on the top of the egg again and smashed some egg shells.

"But after the stone pillar rises, the stone bed where the sarcophagus is placed is stuck here, and it can't rotate."

Wumei stared at the egg, licked his lips, and swallowed his saliva: "But, why does it turn?"

Zhang Ping held up the egg and said solemnly: "Turn, it's the mechanism."

Wang Yan looked around: "You are a little confused when you transferred our headquarters."

Lan Jue said in a warm voice: "The meaning of Zhang Magistrate Zhang is probably that this hall is an inverted maze array. It is similar to the Bagua Magator listed in the book. However, the Bagua Magator uses a formation to trap people, making it difficult for people to distinguish between east, west, south and north, and it is difficult to distinguish between the Life and Death Gate. However, this hall uses magnets and misguided hexagrams to confuse the direction, and then use the power of the mechanism to rotate the walls and ground, trapping people in it."

Zhang Ping looked at Lan Jue with bright eyes, and Wang Yan raised his eyebrows: "It sounds very precise, but it is useless in this case. Since there is such a mechanism, why do the woman in the coffin smash mercury, throw a bottle, and turn it around directly, trap the criminals here, fight for one and die together, and starve them to death, wouldn't it be?"

Zhang Ping said: "She must press that mechanism and close another door. The lower official can't fully infer why she gave up the opportunity to start other mechanisms and press that hexagram first."

Lan Jue had already walked to the mechanism where the stone pillars were raised, and he also discovered the mystery. In fact, all the hexagrams were composed of nine small stone bricks, but the vermilion color made people ignore the gaps in it, making people directly believe in the image drawn.

After seeing through it, these tricks are actually very simple, but if you neglect, you will be misled.

It is like passing through a curved and oblique passage, entering the Xuan Palace, and then seeing the bronze statue of Hewang, you will subconsciously feel that the underground palace is inverted between the earth and the sun, and the first direction on which the bronze statue should be located south and north. The door behind the bronze statue should be the north of the round hall behind, so you believe in the hexagrams on the ground, which are confused and inverted.

The mechanism pressed by the woman in the coffin is the Li hexagram, but the three straight roads are trapped, Gan.

Dan, this is the south, which corresponds to the sky.

What is the real meaning of opening the Tianmen and sending me back to Quetai?

Wang Yan stared at Zhang Ping who took out a piece of paper and wrapped the egg: "What you said about closing another door is definitely not referring to the stone door of this hall."

Zhang Ping bowed and said, "Report to the master, the door is below."

Wang Yan narrowed his eyes: "Is that sure?"

Zhang Ping held up the egg and raised his head slightly to indicate the top.

"Sir, if there is opening, there will be a close relationship."

Wang Yan looked up at the dome, then withdrew his gaze and looked at Zhang Ping: "How many boiled eggs have you brought?"

Zhang Ping was stunned, Wumei coughed, and secretly pulled his sleeve. Zhang Ping took out another intact egg from his pocket and presented it with both hands.

Wang Yan took the towel from the guard, wiped his hands, took the egg, knocked on the guard's knife handle, and peeled it open. Zhang Ping took out another egg and Feng and Lan Jue.

Lan Jue took it with a smile. Zhang Ping took out another paper bag, which contained three buns.

Wang Yan said: "You have brought a lot of dry food."

Zhang Ping looked at the guards and the guards beside Wang Yan hurriedly said, "Sir, please give up your own use. You are not hungry."

Zhang Ping handed the bun to Wumei, Wang Yan swallowed an egg, waved his hand to signal the guards who came up to report the safety of the Yin-Yang Pool to wait for a while.

"Just eat quickly, and then go to another layer after you finish eating."
