Dantaiyue lived in wuyinmen as a child and read ancient books. Although the stone tablet in front of her is very old, she can still recognize some of the characters.

Although it's not complete, it's also very helpful for them to open the secret channel at the bottom of the lake.

"What is the meaning of the writing on the stone tablet?"

Chen Tao turned his head and looked at tantaiyue. He always felt that the strange pattern in the middle of the stone tablet seemed familiar, but he couldn't remember where he had seen it.

"The spirit of heaven, the spirit of earth!"

Dan Taiyue's mouth slowly spat out such a sentence, then, she shook her head and said: "the remaining handwriting is too old, I can't distinguish, but if you want to open the mechanism, I'm afraid you still have to start from this pattern."

Chen Tao stares at the revolving pattern on the stone tablet, and suddenly feels that a wisp of flame jumps out of the pattern and comes straight to Chen Tao's eyebrow.

Chen Tao suddenly felt a pain in the center of his eyebrows, and he felt a strong burning pain. Subconsciously, he reached out and stroked the center of his eyebrows, and snorted,

he felt that there was a burning meteor falling from the endless darkness in his sea of Qi and snow mountain.

At the moment, the nearby Tan Taiyue also noticed that Chen Tao seemed to have something wrong. She hurried over and asked with concern, "Chen Tao, what's the matter with you?"

"There is a wisp of flame into my eyebrow, extremely painful."

Chen Tao's mouth twitched a few times. When he released the palm of his hand, she exclaimed: "Chen Tao, there is a mark on your eyebrow. It's like a fire..."

Chen Tao stretched out his finger and gently touched the flame mark on his eyebrows. After a few flashes, it disappeared.

After the mark of the flame penetrated into Chen Tao's eyebrows, he seemed to understand the meaning.

"Chen Tao, how do you feel now? Is there any discomfort? "

Dan Taiyue is worried that the flame mark will hurt Chen Tao's divine consciousness, so she is ready to cast the pure heart curse of the fog hidden door at any time.

Chen Tao waved his hand and said, "I'm ok. I seem to know how to open the seal of the stone tablet."

Chen Tao felt that his head was swollen and painful, and there was a strong

message flowing into his divine consciousness, which was ancient and obscure, and could not be completely accepted for a moment.

However, Chen Tao heard a voice in his mind to remind him: "the fire of blood leads to the opening of gold and stone!"

After a moment, Chen Tao gradually calmed down, his forehead exuded a layer of sweat, and then suddenly reached out and bit his finger.

Tan Taiyue saw that, there was no time to stop him. Chen Tao's bloody palm had already been printed on the mark of the flame on the stone tablet.

The blood instantly covered the mark on the stone tablet, the light exploded, and the stone tablet began to shake violently.

Chen Tao and Tan Taiyue subconsciously step back a few steps, looking at the shaking stone, accompanied by a huge sound, at the foot of Chen Tao cracked a stone.

The crevice slowly widened to reveal a hole, with winding steps spreading downward.

Chen Tao and Tan Taiyue look at each other and look at the dark hole below.

"Why can your blood untie the seal? Do you have any connection with the people who built the Taiji map and Dharma array underground in Jiulong village Dan Taiyue looks at Chen Tao with some doubts, and some kind of speculation emerges in her heart.

"First of all, let's go down and have a look. The array eye should be down there."

Chen Tao jumped into the hole first. Tan Taiyue worried that Chen Tao would be in danger and immediately followed him.

When two people go into the dark hole, the pulse bead in tantaiyue's hand becomes more and more bright.

Chen Tao takes out his mobile phone to light it up. The steps in front of him are extremely slippery. The stone walls around him are covered with moss. Within the range of the mobile phone, Chen Tao can vaguely see some murals on the stone walls on both sides.

Then, the two men stopped, put aside the moss on the stone wall, studied it carefully, and found that the deeds recorded on the stone wall were ancient things.

"It's like the sacrifice in ancient times."

Dan Taiyue pointed to the carving on the stone wall. There was a man standing on the high platform, his hands open, accepting something to the sky.

The next mural shows a flame falling from the sky, and the underground people immediately prostrate on the ground and kowtow.

After the worshipers accepted the flame, it suddenly rose. They saw that the whole sky was submerged by the flame, and the people creeping on the ground were scared and ran away.

But these people did not escape, they were engulfed by the fire. At this moment, a figure suddenly appeared, holding a bowl like object in his hand. He floated into the void, and after a great war, he led the flame into the bowl.

However, as Chen Tao and Tan Taiyue continue to look at the murals, they find that the murals have been destroyed.

"What happened after that? Why were murals destroyed? "Chen Tao knew that the flame on the mural and the flame that rushed into his eyebrows seemed to be the same.

"It seems that this underground hole is even older than the time when the Taiji diagram array was built. Maybe it was the elder who didn't want to let the later generations know what happened on the mural."

Tantaiyue frowned and her soft voice spread far underground.

Chen Tao took a look at the dark passage in front of him, and said in a deep voice, "let's go back and study the murals. We'd better find the earth vein first."

"The earth vein should be deep underground. As long as we follow this passage, we should be able to find it."

Dan Taiyue put away the doubts in her heart, and Chen Tao, one after the other, groped along the passage.

As she went deep into the ground, a gloomy breath came, and the probe beads in tantaiyue's hands became more and more transparent.

"It seems that we are not far away from the earth."

Dan Taiyue clenched the pulse probe bead, applied the earth source skill, and began to explore the location of the earth pulse.

However, after some exploration, tantaiyue did not find the specific location of the earth vein. They could only follow the stone steps to the huge cave at the end of the passage.

The stone cave is extremely wide. It is obvious that someone opened up such a space at the bottom of the lake. It is surrounded by stone walls. Although the stone slab at the foot is not very flat, there are obvious signs of artificial excavation.

"This is the depth of the earth. Why don't you see the locked veins?"

Chen Tao searched here for some time, and found nothing except the surrounding stone walls. There was no trace of the earth vein. Dan Taiyue immediately clenched the pulse probe bead in her hand, operated the Diyuan Gong

method, and explored it carefully. A moment later, she opened her eyes and looked at the stone slab under her feet.
