"Whew-whew-"

In the underground world under the yellow sand, Yi Yun could feel a hot wind blowing in his face, blowing his body as if it was about to burn.

You must know that Yi Yun is a cultivator of the Pure Yang Law, but even so, he feels that it is not easy to bear it, which shows the tyranny of the Pure Yang Yuan Qi here.

Yi Yun kept descending, and he fell tens of thousands of zhang, and he couldn't see the bottom of this hole.

It wasn't until about 100,000 zhang deep that Yi Yun saw a vast underground lake.

There is a lake under the desert, which really makes Yi Yun feel incredible.

However, Yi Yun was taken aback when he saw the water in the lake, all the water in the lake was dark red, and waves of heat came from the surface.

Yi Yun looked closely, but found that the lake was not water, but like molten metal.

If you look at the rivers that flow into the lake, they are also flowing molten iron.

Such a river...... Lake, if this molten iron evaporates, will there be a rain of iron sand?

These thoughts flashed through Yi Yun's mind, and he deeply felt the wonder of the world.

At this moment, Yi Yun suddenly felt a chill in his heart, and he looked back, in the dark river of molten iron, a head poked out silently, and a pair of empty and godless eyes were staring at him.

What is it!?

Yi Yun was vigilant, this head was the size of a basin, and its facial features seemed to have been burned off by molten iron, leaving only holes one by one, how terrifying it looked to be.

Crash!

The head leaped out of the dark river of molten iron, splashing molten iron and scattering in all directions.

This is a humanoid creature, three meters tall, thick arms are about the same thickness as Yi Yun's thighs, its whole body muscles are pierced, it looks very strong, his body is wrapped with red chains, and he holds a thick-backed knife more than one person long in his hand, and the molten iron keeps rolling down its skin as it walks, and after it cools down to the ground, dark red steel balls are formed.

Monster or human?

Yi Yun didn't expect that there was such an indisputable thing in the underground world.

Boom! Boom!

The weight of the humanoid creature was very terrifying, and it could step on a deep footprint with one foot, and what made Yi Yun feel frightened was that the aura of this humanoid creature was very powerful, and it was better than his own.

"Boom!"

The humanoid creature suddenly burst out, smashed the earth with one foot, and slashed at Yi Yun with a knife, there was no law comprehension, no sword intent, but what it possessed was terrifying speed and power!

Yi Yun's heart was shocked, this sword was too fast, and the speed exceeded the speed of his sword by several times!

Three-foot time sword!

The speed is not enough, use the law to make up for it!

Yi Yun distorted time and space with a sword, forming a space-time cage, but before this cage could be closed, it was broken by a powerful force!

The warrior's attack is extreme, and it can shatter the void, and this knife of the humanoid creature at this time is like this!

Click!

The power of time and space exploded directly, and Yi Yun had no choice but to use the Pure Yang Broken Sword to block this blow head-on.

Clang!

The swords struck, and the powerful impact swept through Yi Yun's body, Yi Yun only felt that his arms were numb, his body shook heavily, and the tiger's mouth was directly torn apart.

He snorted, a bloodshot spilling out of his mouth.

What kind of strange force is this!?

Yi Yun was completely surprised, he didn't even understand what the other party was, he was attacked by a head and face, and its strength was so terrifying!

A simple flat slash, when the speed and strength are both extreme, but there is such power.

Crash!

Yi Yun had just barely resisted this slash, and the chains of the humanoid creature were thrown at Yi Yun again!

The iron rope roared, as if it was about to split the space in two, Yi Yun's pupils shrank, and his body exploded!

He knew very well that he couldn't use his sword to block this iron rope at all, otherwise the iron rope would entangle the Pure Yang Broken Sword, and he would even have to take his sword away.

Yi Yun stepped back a few dozen feet, and then he stabilized his pace, he clenched the Pure Yang Broken Sword, and his eyes became solemn.

This humanoid creature, not to mention the attack power, the defense power is also very amazing, fighting with it, Yi Yun didn't dare to fight hard at all, in this dangerous and unknown underground world, being injured is not a joke.

He can only break with skill.

"This monster's intelligence shouldn't be high, I'm going to outwit ......"

Yi Yun stretched out his palm without leaving a trace, a small black roulette wheel rotated in the palm of his hand, Yi Yun had already decided to look for an opportunity to punch the Ten Thousand Demon Life and Death Wheel into the body of this humanoid creature, in this way, no matter how strong the opponent's defense was, it would be useless.

But...... Just as Yi Yun was about to act, he stopped, and the Ten Thousand Demon Life and Death Wheel that had just been condensed in his hand also dissipated.

The scene that happened in front of him made Yi Yun only feel a trace of cold air rising from the soles of his feet, rushing straight to the heavenly spirit.

Behind the chained humanoids, in the slowly flowing river of molten iron, seven or eight more heads emerged one after another.

Each head was the size of a basin, and its facial features were hollow, as if they had been burned off.

And then, in the center of these seven or eight heads, a larger head emerged, this head is no longer the appearance of burnt facial features, but has clear facial features, and there are some metal pieces condensed on its head, like a simple helmet.

This humanoid creature with a helmet, with an even more powerful aura on its body, is clearly the leader of the other humanoid creatures.

So much!?

Yi Yun felt bitter in his heart, he might not be able to deal with any of them, seven or eight at once, and there was a stronger leader!

In this underground world, there is such a terrifying existence, if there are more of these terrible things, I am afraid that the Seven Star Dao Palace will be destroyed by them.

Originally, Yi Yun knew that the things buried in the sea of sand were very good, but now it seems that he may still underestimate it.

Escape!

If you can't beat it and don't run, you're going to die.

Yi Yun didn't think about it, turned around and flew away, he soared his speed to the extreme, and at the same time applied the laws of time and space.

"Roar!"

The humanoid creatures let out a dull roar and chased after Yi Yun!

Their muscles bulged and they raced quickly on the ground, the ground trembling with the violent impact of their soles against the ground, and the scorching sand that was raised flew into a long dragon.

Yi Yun's speed was at full speed, and he couldn't get rid of these humanoid creatures, but was chased closer and closer by them.

Especially the humanoid creature in the lead, it was four meters tall, and its speed was a cut faster than Yi Yun!

It's going to be overtaken!

Yi Yun felt a chill in his heart, once he was caught up, he was afraid that he would be dead!

However, at this moment, something happened that made Yi Yun feel desperate, he sensed and probed out, and found that he had run to the end of this underground world!

Although the underground world is vast, Yi Yun originally appeared at one end of the underground world, and now he naturally runs to the point where there is no way out!

Heaven forbids me?

Yi Yun's mind is in a hurry, seeking possible vitality in the land of death!

However, at the moment when he had no way to go to the sky and no way to enter the ground, a slightly old voice suddenly sounded in Yi Yun's ears - "Come to my side!"
