After the golden light passed through the hole, the seven target points were the jade gui in the hands of the civil official, the light points coincided with the groove, impartial, just right, Song Siyuan finally knew what the role of the red gold copper slip was!

They have always been curious about why the Chao family emphasized that the key to the Soul Palace was found on the red gold copper slip, and they didn't think that the copper slip was of any use along the way, it turned out that they just didn't know the use of the fire.

"If Tong Jian is in the Haidong Imperial Mausoleum, how did the emperors of Li Tang enter the Soul Palace to worship?"

Xu Xiake looked at the red gold copper slip, and saw that the use of the copper slip was true, and he couldn't help but say the doubts in his heart.

"I guess that the seven positions of the bronze man must be in the hands of the emperors of the past dynasties, but they don't know that when Yuan Tiangang and Li Chunfeng were making the organ, they also made a red gold copper slip privately to hide the secrets of the organ, no matter what they were thinking, at least we found the organ, everyone hurry up to see the bronze man, how to make a deal to open the ghost door."

After finishing speaking, Yue Guanchao and they walked to the middle of the bronze official, the distance between the copper officials is mostly an arm's length, which can allow a person to pass flat, and when looking down at the hem of the clothes, you can see that there is about half a gap between the hem of the clothes and the ground.

He moved back and forth with the civil figurines in his arms, looking like a mechanism but not moving at all, and everyone was the same, looking at each other.

"Could it be that we guessed wrong?"

Song Siyuan walked away and looked at the civil figurines, who were holding wat boards in their hands, which attracted her attention.

She walked to the front and took a closer look, the hands of the civil figurines holding the wat board, you could see the seam between the hand and the arm, and she turned back and forth on the wat board.

With a click, she turned her wrist downward when the wat board was pressed down, and she turned the bronze figurine again, and sure enough, it could rotate clockwise.

This is obviously the way the organ is opened, and everyone just now also saw her approach, according to Song Siyuan's method to draw a scoop according to the gourd, the seven bronze figurines rotated in turn, and the rumbling sound was endless.

After the seven bronze figurines were completely displaced, the deer platform shook violently, and in the expectation of everyone, it can be seen that the array under the stage stopped shaking, but after a cup of tea, the ground closest to the deer platform was already seen rumbling forward, and the cast iron terracotta warriors and horses moved backwards.

When the roar was completely over, Yue Guanchao and the others accepted the copper slips, and got off the deer platform to the ground.

This dark underground entrance just occupies two phalanxes, and the distance between the front and back is about ten meters, even if you fill in a house, you can live in it.

"I thought that it would be the bronze ghost gate that was opened, why didn't Li Tang's people eat the bronze door, and they had to open a new door on the ground."

Xu Xiake's questions were also curious, Song Siyuan looked at the giant gate behind him and explained: "Li Tang's people are probably not able to open the bronze ghost door at all, they can't open the door, they can only open the side door underground, and at the same time, they can also use the side door to create a mechanism, which confirms our previous guess, they are indeed doves occupy the magpie's nest and make things in the ghost gate." ”

"It is estimated that this bronze door can only be opened by the ancient Chu ancestors."

Yue Guanchao turned on the flashlight, inside was the steps that kept going down, they took a deep breath, lit the faint lamp and walked into this dark space, although the steps were steep, they were not much, about nearly a hundred steps later, a forked platform appeared.

Everyone diverted down the Y-shaped staircase, bypassed the staircase to the front of the platform, and a round arch went out, and appeared in front of them.

"According to the location we are in, it should be the underground of the ghost gate, and I don't know what will happen after we walk in, everyone pay attention to safety."

Saying more unintentionally, they passed through the arch cave and came to the cave behind the ghost gate!

Yue Guanchao's vision passed through the darkness and gradually became brighter, and the world behind the ghost gate gradually spread out around everyone.

"It turns out that the underground rivers that disappeared have all gathered here!"

In front of everyone, a vast underground lake appeared, the area was so large that it was more than half the size of the military position cave they had seen, leaving only a rock wall tens of meters wide to form the lakeshore, countless wild grasses and mosses covered the ground, and it was rare to see bare cold rock formations.

They walked along the rugged shore of the lake to the lake, and they could see that the water surface was cold and cold, and the countless mist rippling on the water surface formed an ethereal clear smoke floating on the surface.

Only some of this light came from their flashlight, and most of the light came from the light hole at the top of the sky, which was supposed to be artificially chiseled, like a disc that introduced sunlight into the cave, sprinkling a rich white light, illuminating the center of the lake, just reflecting the water surface like gold and silver, sparkling.

For a while, everyone seemed to see the sun again overhead, because they had stayed in the dark cave for too long, they didn't dare to look directly at the light cave, and their noses and eyes were red because of the bright light.

The most peculiar thing is the ancient locust tree in the center of the lake!

This locust tree is produced from the groundwater, as thick as a house, the branches cover the sky and the sun, the top is connected to the stone wall, the surface is covered with vines Ganoderma lucidum, and thousands of branches strive to grow densely upstream, like the mythical Tongtian God Tree.
