Ling Yun could faintly hear rustling sounds coming from the distance, like a snake swimming, as an aura swept towards the pit.

"What is it?" Ling Yun's expression became serious, this was the belly of the mountain, under the ground, what kind of snake could move about unhindered?

Earth Worm Python?

Impossible, this is not the aura of the Earth Worm Python.

Jade Horned Serpent? Impossible.

There were too many types of snakes in the world, and it could be said that they were the most of any species. There were at least a dozen or so species of snakes that could drill through the ground.

Moreover, most of them had only heard about it and had never seen it before. Naturally, they were not clear about its aura.

The snake was still quite far away from where they were. Of course, this so-called 'far' should be about two or three hundred meters away from the dark, lightless cave.

Furthermore, the surrounding rock layers were extremely thick and were as hard as iron. The major powers had laid down a Spiritual Array that would greatly weaken the range of the spiritual will. Thus, it was impossible to determine what it was.

A big battle was unavoidable, but in this place, they had their reservations and didn't dare to let go.

If they were to make a huge move, it was very likely that the mountain would collapse. At that time, even if the two of them didn't die, they would most likely be trapped in this place.

On the contrary, the snake-like creature was able to move underground. It could be said that it had the advantage here, and their situation was extremely bad.

He did not believe that this snake happened to pass by by chance. Snakes were blind, but the snake's tongue was sensitive to auras and could sense the breath of life from afar.

Neither he nor Ling'er noticed that wisps of invisible smoke had attacked them and blended into the air, then flowed into their bodies through their breathing and slowly precipitated …

"Ling Yun, don't you still have the Escape Symbol, Thousand Li Rune and the Escape Rune? If we take one out, won't we be able to leave? " Ling'er said as he shrunk into Ling Yun's embrace, as if he remembered something.

Ling Yun laughed bitterly. If it was useful, he would have used it long ago, why wait for Ling'er to remind him. He said helplessly: "I don't know if this place is special or sealed by a major power.

"What kind of bastard is this, to be so bored that he runs all the way to this crappy place?" Ling'er scolded angrily. Some special terrain could indeed seal space and prevent Escape Symbol from being used to teleport there. However, that place was very rare and she did not believe that she would be unlucky enough to encounter one.

However, teleporting into the depths of the mountain was one of a million, and they still encountered it. Coincidentally entering those special places was also very possible.

Ling Yun tried to activate the Holy Spirit's pupil to see if he could see anything. He did discover something, he saw that the hard stone layers were covered with dense spirit engravings.

Moreover, the Spirit Marks were special. They made it so that his eye technique could not see through them. He wanted to see what the snakes that wandered over were.

"Hmm?" Ling Yun's eyes suddenly widened, and immediately after, he gnashed his teeth and cursed: "Bastard!"

A few lines of small words were left on a stone wall as far as his eyes could see, "Later, congratulations, come to the belly of the mountain. Let me tell you, when I am bored, this place is engraved with a Spirit Sealing Rune, you are not allowed to go in or out. Don't try to break it.

It was as if he could see the gloating expression of the person who left the message, and his expression was one of unbridled joy.

"How f * cking boring are you!" Ling Yun scolded, his body trembling in anger.
