The sudden change caught them off guard.

Soon, after a large area of river water poured in, the ancient dead insects that were still active in the ruins were flooded in it.

In the midst of their screams, they turned into pieces of black water and died completely.

But at the same time, the rapidly surging water level also makes them precarious in the river.

"Find a place to stay, if we continue like this, we will also be drowned!"

Lin Yu held the lantern and shone towards the heights.

Inadvertently, he saw a slightly higher terrain and immediately pointed to it.

"Let's get there, maybe it's safer!"

"No problem, you're sure!"

The old mountain demon responded, and then waved its strong limbs and began to swim quickly in the icy water.

The mountain demon's swimming talent seems to be innate.

The old mountain demon slid quickly through the water, and after passing through most of the area, they managed to get close to the high ground.

As the underwater horizon climbed, the old mountain demon finally surfaced, but after a few steps, it stopped, and then looked straight ahead.

It turned out that when the river leaked, some ancient dead insects, in order to avoid the water body, relied on instinct and also came to this high place.

At this time, they were tightly hugging into a ball, sticking to the ground, forming a huge black pillar on the ground.

By virtue of this approach, most of them have managed to avoid flooding.

"It's not good! They occupy the place we fancie! ”

The water level in the space-time cave was still rising rapidly, and while the old mountain demon was speaking, the water level had already risen from its calf to above its knees.

It won't be long before the river will flood over their heads.

However, there were countless ancient dead worms in front of them, and they couldn't take another step forward.

"You try to keep your balance, I'll take care of it here!"

Lin Yu also noticed the situation ahead, he hung the lantern on the horn above the old mountain demon's head, and then jumped down.

The river that drowned to the knees of the old mountain demon almost reached his neck.

Lin Yu spit out the river water in his mouth, and after that, he took out his black sword and aimed it in front of him.

"I'm going to try to light it down this time, but the water is too strong and it might affect me! If I can't hold it up, you'll find a way to get me! ”

"No problem, I'll look at it! Why don't you stand on my hand and I'll send it to you? ”

"This method is not appropriate, you take care of yourself first!"

The underground water flow is particularly turbulent, there are undercurrents everywhere, the old mountain demon stood behind him, and used his body to help him block some of the turbulent river water, taking advantage of the calm level of the surrounding river now, Lin Yu told the old mountain demon to endure the extremely low temperature of the river and rush forward.

When his body came out of the water, ancient dead insects began to appear around him.

Although they are afraid of the river, they are even more difficult to control in the face of fresh life.

For a time, countless ancient dead insects swarmed in.

Some of them fell into the water and were dissolved by the water, but most of the rest crawled past the corpses of their own kind, which had not yet been completely dissolved, towards Lin Yu.

"Die!"

Lin Yu could also feel those insects crawling towards him in the dimness.

After silently counting the three numbers in his mind, he slashed out with all his might.

As the sword qi dissipated, a black flame burst out silently.

In the darkness, countless ancient dead insects, burning with black flames on their bodies, fell into the water.

But more ancient dead insects also came at the same time, they crowded each other, wriggled and wriggled against each other, and some unfortunately fell into the water and were dissolved by the water.

All the sounds, intertwined, to form a slimy and suffocating noise.

Lin Yu stood in the water, the temperature of his body began to drop, he trembled, and his upper and lower teeth couldn't stop fighting.

But he still held on, silently reciting the numbers in his heart.

One, two, three...... A sword swinged.

The cycle repeated, until he didn't know how many swords he had, his hands were no longer able to lift up, and the black sword fell into the water, making a crisp sound, and then disappeared.

And in front of him, countless insect corpses floated on the surface of the water like black foam, up and down.

"Enough! They can't stop me anymore! Hero, you did your best! ”

The old mountain demon saw that the ancient dead insects had collapsed into a swarm, so it moved its body, crawled forward, and walked with difficulty in the turbulent river.

When it came to a high place and pushed all the remnants of the ancient dead insects on the ground into the river with its hands, the remaining insects around it could no longer pose a threat.

At this time, Lin Yu, who had exhausted his strength, fell wet on the insect corpses all over the ground, panting heavily.

The old mountain demon sat on the stone next to him, took off the lantern on the horn with two fingers, and then placed it on Lin Yu's chest.

It looked at the exhausted Lin Yu and praised: "You are worthy of the hero I am optimistic about, you are very powerful, and you have once again let us out of trouble!" You are the dragon's Kwanalin! ”

From its mouth, Lin Yu heard that unfamiliar word again.

He turned his head weakly and asked, "What does this mean, Quanarin of the dragon?" ”

"Hmm! I forgot, you don't have the knowledge I have, and Quanarin is the champion and winner of the ancient dragons' language. Because their voices are a little different from those of current spirit animals and humans, I can only explain some words to you by simulating similar sounds. ”

"So, now your explanation, no longer needs to be priced?"

Lin Yu still didn't forget the price that the other party kept repeating when he first saw this old mountain demon.

"That's just an excuse, because my knowledge is precious, and it's all precious treasures that I have lived for thousands of years!"

"And now?"

"Wealth is far less important than life, I want to go out, get out of here, go to a place with sunshine!"

"Huh! Really! ”

"Haha!"

The old mountain demon made a rough sound with him, and after laughing for a while, it suddenly stopped.

"Hero, you have a name, right?"

"Of course, every person has a name! What about you? ”

The old mountain demon scratched his rough scalp, and his deep eyes were wrinkled.

"The mountain demons only roar, they can't speak, so we used to use our voices to distinguish each other, but now it's different! I'm the only one in the mountain demon clan who can communicate with humans normally, so there should be a title, but my knowledge is not used to adapt to this. ”

"Then I'll call you the old thing! Anyway, you're so old, and if you don't die old, you're a thief! ”

Lin Yu lay on the ground and said with his arms on his pillow.

"Old thing? It's not a nice name, but it comes from your mouth, so I reluctantly accept it! ”

Then the old mountain demon let out another heavy, bold laugh.

After that, the water level in the cavity underneath rises at an extremely slow rate.

Most of the underground has been submerged by the water, and the ruins have sunk to the bottom along with the ruins and the ancient dead insects within.

"Looks safe for now!"

Lin Yu rested for a while and finally regained some strength.

He sat up and prepared to wash the stains off his body with water.

But when he reached the water's edge, as soon as his hands touched the water, they were stained with a layer of viscous black objects with a pungent smell.

He quickly got up and left the water's edge, calling backwards at the same time.

"Old thing, give me some light!"
