The sun gradually rose from the East and came to the middle of the sky, burning the yellow sand on the ground.

Somewhere in the vast desert, you can see a big pit on the ground. If you observe it carefully, you will find that there is a pyramid in the pit. The depth of the pit is at least hundreds of meters, and the height of the pyramid seems to be more than this figure.

If you stand on the edge of the pit, you can still see that from time to time, groups of yellow sand wrapped by Lingli rise up from below, fly to the distance, and then be poured out again.

At the bottom of the pit, Yun batian and Yang Xuan are constantly using their spiritual power to carry the yellow sand below in order to see the true face of the pyramid.

Unconsciously, they have been tossing about all morning. Finally, when Yang Xuan wrapped the yellow sand with his spiritual power, he found that he had touched a hard thing. Remove all the yellow sand on this thing. Yang Xuan just found out. This is a huge slate.

The whole pyramid is placed on this stone slab, which extends into the yellow sand and seems to be farther away.

On the other side, yunbatian, whose progress is only a little slower than Yang Xuan, has also touched the bottom. After they looked at each other, they stopped at the same time.

Around the pyramid, there are still less than one meter thick gravel. In other words, apart from these places, the whole pyramid has been displayed in front of them.

This is a pyramid with a height of more than 300 meters. The whole body is made of stones, and the surface is very smooth. Although you can see the gap between each stone, Yang Xuan tried and found that the gap was so close that he couldn't even insert a hair.

Yang Xuan was surprised to find that it seemed to be a solid pyramid, because his divine sense could not go deeper.

The bloody jade piece in yunbatian's hand still reacted violently, but they didn't find any clues related to the secret place here.

"Could it be that we missed something and didn't check it?" Yang Xuan thought and explored the whole pyramid up and down again. This time, he didn't just touch the pyramid with divine knowledge, but wanted to find the hidden mechanism.

But a few hours later, they were tired and panting, and there was still no result.

Yunbatian sat on the ground and said to Yang Xuan reluctantly, "it seems that we should have found the right place, but only when the secret place is opened can we see the real appearance of the blood burial secret place."

"Maybe." Yang Xuan also reluctantly agreed. Otherwise, he couldn't explain what happened to the tightly fitting pyramid.

Yang Xuan sat on the ground and looked around to see what he had left out. Suddenly, out of the corner of his eye, he saw something on the ground, which made him jump up suddenly.

But after he stood up, he found that the ground was still empty.

"What's the matter?" Seeing the movement of Yang Xuan, Yun batian asked puzzled.

"I seem to have seen words on the ground just now." Yang Xuan observed the ground as he spoke, but after a while, he still got nothing. In desperation, Yang Xuan had to scratch his head and said reluctantly, "it may be my illusion."

When yunbatian saw Yang Xuan, he didn't find it, so he didn't continue to check. He sat on the ground, knocked on the ground with his hand and said, "the floor is quite hard." Then, under the trend of curiosity, he hit the ground with his fist with psychic power.

But I don't know what the stones that paved the ground are made of, but they are undamaged. You know, even if yunbatian didn't use much force just now, he can still smash a kilogram boulder. However, after hitting the floor, the ground was intact. The strength of the rebound also made yunbatian absorb cold air for a while.

When Yang Xuan saw yunbatian's embarrassment, he immediately laughed. Yunbatian also stared at Yang Xuan helplessly. At this time, he suddenly found that there was a burst of light under his body.

"What's going on?" Yunbatian looked at the light on the ground as if he had found a new world. The light shines as like as two peas of Yang Xuan's hands.

The red light extends in a straight line, then divides into two and continues to spread in two opposite directions. The light extended so fast that a picture was drawn on the ground in the blink of an eye.

"Is this a hidden array?" After the red light, Yang Xuan had already flown up, and then he saw that the red light on the ground had formed a strange scene.

"Has anyone finally come here?" A voice suddenly sounded. Yang Xuan turned his head and looked at Yun batian: "brother batian, did you hear anything?"

"Yes." Yun batian nodded, and the expression on his face was very serious.

"Cough, don't be surprised. It's me. My name is Gu Tiannan. You can also call me Tiannan venerable or Tiannan Taoist friend." The sound sounded again, much clearer than the vague sound when it first sounded.

"Tiannan venerable?" When Yang Xuan heard these four words, he suddenly became vigilant. From the vision just appeared, the owner of the voice should have fallen asleep again for a long time, and it should be just a soul. This kind of existence is the most dangerous existence in the immortal cultivation world, because their spiritual power is strong and they may lose others at any time.

"Venerable Tiannan, we came here to find a place called blood burial secret place. I don't know if you've heard of it?" Yang Xuan thought about it and asked in the void. At the same time, he raised his vigilance and was ready to display the Phoenix Sky fire at any time. The lethality of Phoenix Sky fire to the soul is no different from highly toxic arsenic. Only in this way can he fight back if Tiannan Zun is violent.

"Of course I know, because this secret place is what I found and told the world." That day, nanzun didn't mean to make a move. Even now, Yang Xuan and Yun batian only heard his voice but didn't see him.

But from Gu Tiannan's words, Yang Xuan heard some useful information. At least Gu Tiannan knew about the secret place of blood burial.

"I dare ask you, elder, where is the secret place of blood burial, and how can I get in?"

"Hahaha, young man, do you want to enter the secret place of blood burial? But don't worry. You might as well listen to me tell you the origin of the secret place of blood burial, and then decide whether to go in or not?"
