Wu Zhiyuan saw that he was now in the center of an octagonal clearing, which was about 100 feet square, and what surprised him the most was that this octagonal clearing was exactly like the eight sides of the eight trigrams, and there was a bluestone step on each of the eight corners that went straight up, and he walked down from the westernmost step.

Looking at the strange landscape in front of him, Wu Zhiyuan suddenly sighed, and he quickly understood in surprise that there was such a passage leading to this place under each coffin, so it seems that there are coffins in a total of eight houses on the ground, and these eight houses are located in eight different directions, and their positions are exactly the eight directions of the gossip.

Looking at the bluestone steps and blue brick walls, this layout design must have been a long time ago, and it is still difficult to determine which dynasty designed it. Wu Zhiyuan hesitated for a moment, and suddenly remembered the strange woman's cry he heard at the entrance of the hole in the ground, and now he looked around, this open space was completely closed, except for the eight upward stone steps There was no other exit, and the upward stone steps were all leading to the coffin on the ground, where did the woman's cry come from?

Wu Zhiyuan listened calmly, thinking that the cry might sound again, but he didn't expect to wait for a long time, and he didn't hear the weird cry again. He couldn't help but feel a little lost, and he had to go down to the cave with great difficulty, but found nothing, which was really unexpected.

After walking around the open space a few times and not finding anything suspicious, Wu Zhiyuan walked to the stone steps directly west, intending to return to the ground. As soon as he stepped on the two steps, his eyes suddenly caught a glimpse of a recessed hole in the wall due west, which looked like the lamp trough of a wall lamp, but what was placed in it was not an oil lamp, but a thing similar to a bird, Wu Zhiyuan reached out and took the thing in his hand, and took a closer look, only to see that this thing was made of bronze, and its image was very much like a swallow that was spreading its wings and gliding, only the size of a palm, with a unique shape, delicate patterns, and exquisite workmanship, which was breathtaking.

"What is this for?" Wu Zhiyuan put the bronze swallow in his hand and played with it, and subconsciously looked up at the other seven walls, and in the light of the torches, he could vaguely see that there was the same groove in the other seven walls, and the same bronze swallow was also placed in the groove.

Wu Zhiyuan was puzzled, at this moment, he suddenly heard a "bang" sound from the chain pulling in the wall, and then the wall shook, and suddenly all the eight grooves of the eight walls erupted into a raging fire, and eight fire snakes sprayed wildly towards the center of the octagonal clearing, Wu Zhiyuan dodged and fell on the upward steps, so he was not burned by the sudden fire snake.

The temperature in the air suddenly increased, but the recesses of the eight walls were still spraying eight lines of fire, as if there was no intention of stopping. Wu Zhiyuan only felt that the air was hot, and hurriedly climbed up the steps, just after climbing a dozen steps, he heard a "bang" sound similar to that made when a chain was pulled, and the sound sounded from east to north and then west and then on the south side, and then it stopped, and at the same time, the eight lines of fire suddenly stopped spraying.

Wu Zhiyuan was shocked, he looked at the bronze swallow still in his hand, and instantly understood what was going on, presumably he inadvertently took out the bronze swallow in the groove of the wall, so it triggered the mechanism in the wall, so the fire in the groove will breathe.

But why is there fire in the eight grooves, instead of spraying water or other things, Wu Zhiyuan can understand it when he thinks about it in combination with the direction of the eight trigrams, the layout of this cave is secretly in line with the eight directions of the eight trigrams, and what he took away is the bronze swallow in the wall due to the west, and the west belongs to the off-position in the gossip, and the separation represents fire, so there will be fire sprayed out of the groove.

If the guess is correct, take away the bronze swallow on the east position, and there will inevitably be water spraying out. Feeling the scorching heat of the air around him, Wu Zhiyuan planned to take out the bronze swallow due east to try, if it really spewed water, it could also lower the temperature in this cave.

Thinking about it, he put the bronze swallow in his hand back into the groove on the west wall, so as not to trigger the mechanism again, and then walked down the steps, and as soon as his front foot stepped on the stone slab in the clearing, he reflexively retracted suddenly.

Sitting on the steps and waiting for a cup of tea, the temperature of the stone slab on the ground gradually receded, Wu Zhiyuan dared to walk into the open space, he walked straight to the opposite side, just halfway through, at a glance saw the groove in the wall in the south, the south corresponds to the Kun position of the gossip, and the Kun represents the earth, if the bronze swallow of the Kun position is taken away at this time, I don't know what will spew out of the groove of the eight walls?

Without thinking too much, Wu Zhiyuan folded directly in front of the south wall, reached out and took out the bronze swallow inside, and before he had time to look at the appearance of the bronze swallow carefully, he suddenly felt a shaking of the ground, and then "Hulong", the stone slab on the octagonal open space suddenly made a flip, Wu Zhiyuan stepped on the air under his feet, and fell into the unknown deep hole.

Before Wu Zhiyuan could react to what was going on, the whole person fell to the bottom of the deep hole, and his body didn't know what he had hit, making a "click" sound.

Wu Zhiyuan only felt that the bones in his body were about to fall apart, he struggled for a while, but he couldn't get up, and when he turned his head, he found that the torch had also fallen, and at this time it was not far from him, the fire was not extinguished, and it kept beating.

Under this look, Wu Zhiyuan couldn't help but be surprised, only to see that the area illuminated by the torch was full of dead people's bones, and then look at himself, he was lying in the pile of dead people's bones at this time!

Wu Zhiyuan screamed in fright, got up in a panic, accidentally stepped on a round thing under his feet, suddenly slipped, and fell to the ground, he hurriedly stretched out his hands to support it, but opposite the tip of his nose was a terrifying dead skull! The flesh on the skull had long since rotted away, and only a pair of black holes with no eyeballs remained, which was terrifying!

Wu Zhiyuan gasped, and forced himself to comfort himself not to panic, this is just the bones of a dead man. After a moment of self-suggestion, he slowly got up and picked up the torch. Lifting the torch to the level of his shoulders, the light of the torch suddenly illuminated the range of ten feet around him, Wu Zhiyuan looked at it and was immediately surprised!

I saw that the bones of the dead people in the line of sight were like mountains, and in the distance where the light was faintly dimmed, the white bones still could not see the end......
