He was about to continue to introduce the situation at the bottom of the cliff to everyone, when a sudden rumbling sound came from behind him, which made everyone's hearts tighten, and they turned on the flashlight to look ahead, and under the convergence of the flashlight, everyone gradually saw where they were!

The space they are in, consistent with Song Siyuan's description, is a sub-karst cave located below the mother cave, but the sub-karst cave is completely different from the mother cave, and it is a "U" shaped karst cave valley.

The burial chamber they escaped from was built at the bottom of the U Canyon, and the mirror palace with a height of 100 meters was built on the stone walls on both sides of the canyon.

Look closely, this canyon is steep in the west and gentle in the east, the west cliff rarely has a gentle slope, the steep mountain wall is almost straight up and down, there is no possibility of digging the road in the stack, compared to the west cliff, the east cliff seems to be much gentle, all over the trestle and stone road, like a snake eel winding to the front, and then completely blending into the darkness.

Yue Guanchao looked up at the top of his head, the upper karst cave carved out a grotto the size of a roof in the rock wall, and a stone beast was specially carved outside the cave entrance.

This stone beast has a head like a unicorn, antlers on its forehead, and a strong leopard body full of black scales, its front paws are on the ground and its back paws are curled up, its eyes are like copper bells, and its fangs are angry, like a body the size of two private houses, giving people the strongest sense of oppression!

The opening of the grotto was just in the mouth of the stone beast, and in the dark environment, it seemed that a stone beast suppressed the tomb, and the underground spring water was constantly spitting out, causing the water to leap down and boom.

The burial chamber under its mouth has been flooded for several hours, and springs have sprung up from the cracks of the holes everywhere, and have flowed into the canyon by the difference in terrain, becoming an underground silver waterfall.

The momentum of galloping thunder, as if to open the sky and split the earth, the rift valley into a gully, so close, even can feel the mist wrapped in the cold wind paving, blowing people breathless, want to jump in and follow.

"The Stone Beast of Zhenshui turned out to be not a crack in the rock formation, but a mechanism that has existed for a long time."

The moment the cat saw the water beast, the doubts in his eyes gradually became clear, he, like Song Siyuan, suspected that the collapse of the tomb was not an accident but an inevitability, seeing that the water beast was intact, he had another layer of understanding in his heart about the work of seizing the world and creating the tomb of the Mirror Palace.

Song Siyuan nodded at the cat master: "The water inlet and outlet arch hole we encountered in the well pool is probably connected to the town guard beast mouth, usually the water inlet and outlet arch hole is completely closed, when we trigger the first mechanism, the water inlet is closed, the water outlet is opened, and the water in the well pool is quickly poured out, so we can go down the tomb." ”

"Ayinzun is so suspicious, he must be able to calculate that his mirror palace tomb will be patronized by tomb robbers, in order to protect his body, he built a mechanism on the top of the tomb, once his body is out of the pillar, the top of the tomb will collapse out of the hole, and then the mechanism in the well pool will be activated again, and the water outlet and water inlet will be opened at the same time, and this water beast will flow out of the underground spring, completely submerging the entire tomb."

Her words, the cat master naturally knew what it meant, stroked his beard and said proudly: "It's a pity that he didn't see through the death level after all his calculations, and deliberately left a way back for himself, and also asked us to take advantage of him and pick up a life from the tomb." ”

"I guess he is determined to leave the tomb robber in the tomb to be buried with him, then we really don't want the heavens and the earth!"

"This is called Jiren's own natural appearance."

When the cat master shook his head and spoke, Song Siyuan continued to observe the surroundings, although the flashlight was not bright enough, she still recognized the gloomy woods all over the mountains and fields from memory!

On the many slopes close to the east cliff, countless gloomy trees up to tens of meters high are placed diagonally and horizontally, towering like clouds, like mysterious statues standing in the caves, like collapsed broken walls, telling their mysteries for thousands of years with their pitch-black bodies.

"As we guessed, this cave is indeed a gloomy wood, so this also means that most of the bucket arch beams in the tomb are taken out of this sub-cave." Song Siyuan turned on the flashlight, and when she saw that her guess was true, her tone was full of joy.

The cat observed the surroundings and glanced to the side casually, they are all good thousand-year-old gloomy wood, they are rarely inferior, and the black appearance is even wrapped in gold wire, this kind of gold silk gloomy wood is catalyzed by golden silk nanmu, it is difficult to buy an inch.

Seeing such a scene, even the cat master, who was accustomed to seeing treasures, had to admire: "But, how can there be so many gloomy woods here, is it possible that Yinzun really found an auspicious place, and even the rare gloomy woods in the world are too many to count." ”

Song Siyuan observed around, how to say that these gloomy woods are thousands of years old, they have already been carbonized into half trees and half stones in the cave, the surface is like a rock wall, becoming dark and steep, hard and cold, the only thing that can still be seen to be trees is the original flowering and leafy branches, they are gradually wrapped in gum and wax, and after hundreds of years of carbonization, they form full of tree crystals!

With a flashlight, the texture of the flowers and leaves reflects the bright light, like a vortex, like a messy silk, like a velvet ball, just like the crown of the tree branches hung with stars

Seeing that everyone had made the mistake of idealism again, she explained to everyone: "Master Mao, where is this auspicious place, I guess that the entire karst cave is the product of the early volcanic eruption of Changbai Mountain, just a special topography!" ”

"The black forest behind the Jiaolong Temple, that is, after the volcanic eruption, the forest covered by volcanic ash, they luckily did not die, under the arrangement of Ayinzun, it became a bloodthirsty tree with withering outside and glory inside, according to the tracing of the volcanic eruption, we look at the karst cave at present, which is likely to be formed in the volcanic activity of an earlier era!"

"Earlier volcanic activity?"
