Deep in the abyss of the Boundary River.

The place where the inner area meets the central area.

At this moment, there is a figure hidden behind a dark stone.

His gaze kept glancing ahead.

This person is none other than Liu Hao.

He was now observing the situation around him.

Because, he already sensed a powerful crisis.

But it's not sure where this crisis is coming from!

Therefore, he is constantly observing through the Qiankun Heavenly Eye at the moment.

However, what puzzled him was that after scanning around, he didn't find anything.

"That's not right!"

Liu Hao's brows furrowed slightly, "It's definitely not normal to be so quiet here!"

"But why can't I find out where the crisis is through the Qiankun Sky Eye?"

He didn't act rashly.

While thinking, I was still observing.

There is a road straight ahead.

The road is narrow.

Surrounded by low mountain packs.

All are formed by blackstone.

Obviously, these Black Stone Mountain Bags have an impact on Liu Hao's Qiankun Tianyan's penetrating power.

That's why he couldn't see more.

It's just that what he didn't expect was that after nearly half an hour of continuous observation, there was still no discovery.

Immediately, he gritted his teeth, his body moved, and he rushed straight forward.

In his opinion, if there is really a crisis, when he rushes out, he will definitely find out.

But what he didn't expect was that even if he rushed to the middle of the mountain bag, there was still no reaction.

It's as if the sense of crisis is fake.

"What the hell is going on?"

Liu Hao's brows furrowed even deeper.

"There are no beasts here, and there is no breath of life!"

"But the immortal aura is incomparably strong!"

"Most importantly, there is a strong sense of crisis!"

"But there's nothing, you can't sense anything!"

"There's definitely something wrong with that!"

Immediately, he used the Qiankun Heavenly Eye to look around again.

As a result, it's still the same.

Nothing was sensed.

"Hell yes!"

Liu Hao is a little unbelieving.

He headed forward again.

Every time I walked a little ahead, I used the Qiankun Heavenly Eye to sweep the surrounding situation.

In this way, he walked directly out of this low mountain bag, but there was still no gain.

Moreover, what is even more inexplicable is that within a radius of kilometers, there is still no breath of life.

But that sense of crisis has weakened a lot.

If it weren't for the incomparably sharp six senses, he would almost not have sensed this crisis.

"No, there must be a problem!"

The more he couldn't find the source of this sense of crisis, the more unwilling Liu Hao became.

Immediately, instead of going any further, he turned around and walked towards the back.

When he walked to the middle of the mountain bag, Liu Hao stopped.

He glanced at the mountain bags on either side, and then, with a movement of his body, jumped onto the mountain bag on the left, and looked around.

No!

Nothing!

I jumped to the mountain bag on the right and continued to look at it again.

Or not!

Then he stood on top of the mountain bag and did not move.

He frowned and fell into deep thought.

About a quarter of an hour later, suddenly, Liu Hao squatted down and put his ear on top of the mountain bag.

Sneer......

As soon as it was pasted on top of the mountain bag, all of a sudden, an extremely harsh and strange sound came.

It sounded like something was fried in oil.

"Is it down here?"

Liu Hao looked at the black stone mountain bag in front of him, his face condensed slightly.

This is the Black Stone, which has a great influence on his Qiankun Heavenly Eye.

He couldn't see through it.

Again, he couldn't punch it through.

So, what is the situation down here? Is the sense of crisis really coming from here? Liu Hao has no way of knowing!

Immediately, he stood up and prepared to leave.

But, having only taken a few steps, he suddenly hesitated again, and then, crouching down, once again pressed his ear to the ground.

Then, the sound in my ears became a little louder.

"I see!"

After discovering this difference, Liu Hao put his ear on the black stone and kept listening everywhere.

After listening to the mountain bag on this side, he ran to the mountain bag on the other side to listen.

After listening to it once, I listened to it a second time.

In the end, Liu Hao chose a point that sounded the loudest.

"This should be it!"

Liu Hao stared at the loudest point, and then slammed it down with a punch.

Bang!

There is no trace of the hard black stone.

This is normal.

Black stones like this are stubborn stones, and they can't be bitten and boiled.

But......

Liu Hao's fist sank a little.

The part where the blackstone was located also sank a little.

Liu Hao's punch seemed to be smashing on the mud!

Then, from Liu Hao's body, there was a trace of immortal spirit power that began to condense on his fist, and he frantically surged towards the black stone.

Suddenly, the black stone became extremely soft.

Brush!

But after a moment's effort, the black stone suddenly sank, as if it had turned into a sponge, and it sank straight down.

Liu Hao's body lost its center of gravity, and fell directly after it.

......

Whew......

There was a constant harsh sound of wind in my ears.

It is also accompanied by extreme heat.

At the same time, in Liu Hao's sight, a purple flame rose into the sky and burned directly to his feet.

Through the firelight, Liu Hao could see that there were countless holes around.

These holes were large and small, but the huge flames, without exception, did not go towards the holes.

Instead, it just rises in the direction it is in.

It feels as if this is a Dan furnace that is ventilated everywhere.

The flames in the Dan furnace were controlled by people, or rather, sealed, and could not get out.

However, in the holes around them, one or two fairy beasts would run in from time to time.

Then, he was buried in the fire.

Bang!

The next moment, Liu Hao landed.

Then, he saw the bones of immortal beasts all over the ground.

All of them were bones that had been burned to ashes when touched.

Especially in the center of the flame, it was almost a small fire made of animal bones and ashes!

"It turned out to be a mutated immortal fire - Burning Demon Fire!"

At that moment, Liu Hao's face was also slightly moved.

In Liu Hao's cognition, 'Burning Demon Fire' belongs to the mutated species of some special flames.

The conditions for its formation are also extremely harsh.

generated, it must itself be a fairy fire.

This kind of fairy fire has a spirit, but it has not yet been completely formed.

Secondly, nearly ten super powerful demon beasts are needed as burial offerings.

Moreover, these super powerful monsters can't die yet.

There must be a struggle.

In the process of struggling, they will destroy each other with the spirit of immortal fire, and at the same time, they will also merge.

In this way, a mutated special flame can be formed, the Demon Burning Fire!

Then, it will turn into a huge furnace that constantly incinerates demon beasts, and begin to continuously increase its flame intensity!

"Judging from these ashes alone, it is estimated that this 'Burning Demon Fire' has existed for at least a thousand years!"

Feel the power of the flames.

Liu Hao's brows tightened, "I don't know, can I refine this 'Burning Demon Fire'!"

Roar......

Liu Hao's thought had just emerged, and suddenly, in the ashes, there was a shocking roar,

Then, Liu Hao saw a dark purple flame rushing towards him!

Moreover, the heads of many demon beasts actually emerged from this fire......
