Digging less than two feet down, a flat stone surface appeared in front of them.

The four of them swept away the gravel around the stone face, revealing the entire stone face. It was not so much a stone surface as a stone tablet lying under the sand, and the inscription was intricate and intricately notched, and the fifth Tingyun carefully cleared the lines filled with gravel, and then saw the whole line.

This stele is about a zhang long and six feet wide, and if it is erected, it must be a majestic stone stele.

Moreover, the pattern formed by the notches on the surface of the stele was very strange, and they had never seen this kind of pattern anywhere. The four of them squatted around the stone stele, looking at the lines on the stele, and they all remembered the sealing formation that the five elemental masters of the gold, wood, water, fire, and earth systems worked together to build in the hunting operation last time.

Although the formation of the sealing technique is in no way the same as this pattern, it is all the same weird.

Therefore, they speculated that the lines on this stone tablet should be some kind of front, and only by activating these arrays and activating the formation could it be possible to find the entrance to the underground palace. And maybe this thick stone tablet is the gate of the underground palace.

"But how do you activate it?" said Concubine Wanjian, at a loss for help at the stone tablet.

Fifth Tingyun pointed to the lines and said, "Look, what are these?" as he spoke, he rubbed his fingers in the marks of those lines, and when he picked up his hand again, his fingers were bright red, and it was obvious that the dark black material deposited in the lines was blood that had not dried up.

Xiao Mengdie analyzed: "This is likely to be the key to activating the front. Don't forget, the group of people from the Tianshan Sect came here not long before us, and this blood is most likely what they used to open the door of the underground palace. ”

"Reasonable. Concubine Wan Jian smiled, snapped her fingers, and then hurried out of the valley, and went around the high stone wall on the left from the side, for there was still a dead body lying on it. Since activating the formation on this stone tablet requires blood to guide it, then the dead bow-wielding cultivator comes in handy.

It didn't take long for Concubine Wan Jian to drag the dead body back and throw it directly in the center of the stone tablet.

Next, a magical scene happened.

The corpse's shoulders and neck were already bleeding, but as soon as they were placed on the stele, the little blood left in the corpse rushed out like a flood and flowed on the stele's surface. Then, the thick black blood, as if pulled by some force, flowed into the nicked lines. As the thick blood entered the lines, the entire stone tablet bloomed with a dazzling red light.

In the light of light, they only blinked an eye, and they could no longer see any blood, only some black marks were left at the root of those lines, proving that those blood had indeed flowed on the stone tablet.

The stele completely devoured the blood!

Thundered.

At this moment, the earth suddenly trembled, and the fifth hearing clouds understood that the source of the trembling of the ground came from the stone tablet in front of them. They didn't guess wrong, the lines on the stone tablet were the formation that opened the entrance to the underground palace.

The stele shook violently, then retracted backwards, revealing the downward stone steps that had been obscured by the stele.

The four of them hurried over and found that the stone steps were covered with horseshoe prints and human footprints. And the stone steps stretched diagonally down at an angle of forty-five degrees, as if they had reached the depths of the earth, and when they looked down the stone steps, they felt that nothing could be seen clearly in the darkness below, but they could clearly feel that the stone steps were very deep down.

"What do you say?" Concubine Wan Jian flicked her wrist and took out the moonstone from the Sumeru ring, this fluorite itself can emit light, and it is a more reliable light source than candles and torches.

Lei Fengxiang said: "Needless to say, it's all here, can you still give up all your efforts?"

"Okay. Concubine Wanjian walked down first, holding the moonstone in his hand, and he was able to find the way ahead.

They left the horses on the ground and went down one by one. After walking down the stone steps for more than thirty steps, they heard a rumbling sound overhead, and when they looked back, it turned out that the stone monument had been moved back to its original position, and the stone steps leading to the ground were resealed.

"It's fucking too big, how are we going to get out?"

The stele was closed, and there was only a faint light emitted by the moonstone in an instant, Concubine Wanjian ran back a few steps, looked at the tightly fitting stele, and said with annoyance: "This stele weighs thousands of catties to say the least, how can the four of us break it? And there is a formation on the stele, isn't it going to be trapped underneath?"

Xiao Mengdie said: "Don't worry, since the people from the Tianshan Sect have also come down, then they must have a way to get out." The top priority is to find the young sect master first, and after making sure that Bai Jie is safe, then find an opportunity for the Yin Tian Mountain Sect to ask for an antidote. ”

"Yes, Lao Xiao is right. The fifth Tingyun nodded and said, "Let's go." ”

The stone steps were very spacious, and the four of them walked side by side, still feeling a little empty, which showed that there must be a lot of space underground. An underground palace of this scale, buried for dozens of miles outside this Yandang Pass, I don't know how many years, and the things hidden in it can make the Tianshan Sect painstaking, and all kinds of signs show that this underground palace is by no means simple.

I don't know how far I walked along the stone steps, and finally I reached the end of the stone steps, and the road ahead became smooth, but the places where the moonstone could shine were still limited. I don't know how many meters underground, and the surroundings are truly silent, and I can only hear the footsteps and breathing of four people.

After moving forward horizontally for a while, everyone could feel that the space ahead suddenly became much wider. Concubine Wanjian raised the moonstone in her hand, and could see four stone pillars of hugging thickness, this seemed to be a large hall, and some strange patterns were carved on those four stone pillars, and they studied for a while, and found that they could not understand the meaning of these reliefs.

Except for the four stone pillars, this large hall is empty.

"This way!"

Then the glimmer of the moonstone, the four of them searched around the main hall, and after a while, Xiao Mengdie's side seemed to have found something. Fifth, listening to the clouds, they and Xiao Mengdie rendezvous, and Concubine Wanjian stretched the moonstone forward, and in front of her was a two-open stone gate about one zhang high. The stone door also had intricate notched lines, and at this moment the stone door was tightly closed, and under the stone door, a female corpse fell in a pool of blood.

Fifth, Tingyun took a closer look and found that the female corpse had obviously not been dead for long. She was only fifteen or sixteen years old, and she should be one of the many girls who were determined to marry strongly. Her fatal wound was a finger-wide wound on her neck, and it was impossible to tell what sharp weapon had been used to cut it. The upper and lower flesh of the wound were rolled upside down, and the throat inside could be seen directly.

"Looking at the look of fear on her face, did she see something terrible?"

Lei Fengxiang sighed and stepped forward to drag the female corpse to the side.

Fifth Tingyun shook his head and said, "It shouldn't be that I saw something, but I didn't expect Panxin to let her die." You can see the wound on her neck, it's obvious that it's caused by a sharp weapon......"

Before he could finish speaking, suddenly the stone door in front of him shook and opened through the hole.

Concubine Wanjian put the moonstone nearby, and everyone just saw that after Lei Fengxiang removed the female corpse, the blood under the female corpse flowed towards the stone gate like water, and then the stone gate completely absorbed the blood that was about to dry up like thirsty soil.
