Fang Yu jumped into the lake, and there was a dark green in front of him.

The lake is muddy and visibility is very low.

But after entering the lake, Fang Yu could clearly sense a breath coming from below.

It should be the breath of that Cao Tian.

Fang Yu kicked under his feet, rushing towards the position where the breath came from.

......

At this time, Cao Tian was already at the bottom of the lake about 100 meters.

Beneath his feet was the dark ground.

"It's right down here!"

Cao Tian was extremely excited, and his whole body lay on the ground.

Then, his swollen body suddenly shrank into inches, disappeared from the ground, and entered the underground.

This is the innate supernatural ability of their immortal race.

Able to move freely underground.

"I can already feel the scorching heat, it's not far below!" Cao Tian's speed increased to the extreme, quickly approaching the fire in the center of the earth.

At this time, Fang Yu had just landed in the position where Cao Tian had been standing.

"Going down?" Fang Yu looked down at the ground under his feet, his brows furrowed slightly.

He wasn't like an immortal, he couldn't go directly underground.

The only way for him to get underground is to forcibly create a passageway. In other words, to pierce the ground.

Fang Yu raised his foot and was about to step down.

But his feet lifted into the air and suddenly stopped.

"There's no need to rush, let's see what's underground. ”

Thinking so, Fang Yu closed his eyes and put two fingers of his right hand on his forehead.

When he opened his eyes again, Fang Yu's pupils glowed red, and white runes swirled inside.

Now, Fang Yu's vision could penetrate the thick underground soil and see what was below him.

The order structure of the underground was much simpler than that of the ground, and there were many fewer rules and regulations, making Fang Yu's vision particularly clear.

Fang Yu frowned, looked straight down, and soon saw an extremely small outline.

This figure should be Cao Tian.

The reason why it was so small was because he had now entered a very deep position underground, far away from Fang Yu.

"These people move underground with the same ease as we fly on the ground, and the soil itself is solid, but it can't stop his progress, what is the principle?" Fang Yu thought to himself.

Following the direction that Cao Tian was rushing towards, Fang Yu continued to look down.

Further down it was pitch black, and nothing could be seen.

What's going on?

Cao Tian has been going deep into the ground, what is it for?

Underneath the ground, it seems like there's nothing.

Could it be that what Cao Tian wanted to find, he couldn't even see these eyes?

Fang Yu's brows furrowed, looking down intently, and then his brows furrowed.

In his field of vision, where Cao Tian rushed towards, there was actually an extremely small point of light, like a little spark in the night sky.

Due to the distance, this point of light was so small that it was almost impossible to see, so it was ignored by Fang Yu.

"Looks like that's it. ”

Fang Yu stared at this point of light tightly, and then put the fingers of his right hand on his forehead.

The red light in the pupils of the eyes shines even more dazzling!

The white runes in the pupils of his eyes spun rapidly in a clockwise direction.

At the same time, Fang Yu's field of vision began to zoom in!

The spots of light are getting bigger and bigger.

Soon, Fang Yu could see clearly what this point of light was.

It's a fire!

In a small enclosed space thousands of meters deep underground, a fire burns!

The color of the flame is exactly the same as that of other flames, and there is no essential difference.

But Fang Yu knew that this flame was by no means an ordinary flame.

Also known as the Eternal Flame, it is a flame that will never be extinguished!

This flame is said to have existed since the beginning of the formation of the earth.

In the previous immortal cultivation world, many monks spent their lives looking for the fire in the center of the earth.

Just because, the fire in the center of the earth can be absorbed into the body!

Historically, several monks have absorbed the fire of the center of the earth, and then they have all become powerful people and have successfully ascended.

It is said that the cultivation talents of these monks originally belonged to the extremely mediocre category.

But after absorbing the fire of the center of the earth, their bodies have undergone tremendous changes, and they have ascended to the sky in one step!

Their deeds also became the motivation for other monks to pursue the fire in the center of the earth.

However, finding the fire in the center of the earth is quite difficult.

First of all, the fire in the center of the earth exists in the underground, and does not emit a trace of breath.

There is no shortcut to finding it, only luck.

Anyone who can encounter the fire in the center of the earth has extremely strong luck!

And in the entire history of mankind, there are only a few people who have seen the fire in the center of the earth.

As time passed, the existence of the Fire in the Center of the Earth gradually became a legend, and fewer and fewer people looked for the Fire in the Center of the Earth.

Others believe that the fire in the center of the earth is long gone.

Those few great powers have absorbed all the remaining fire in the center of the earth on earth.

Unexpectedly, today, thousands of years later, Fang Yu discovered the fire in the center of the earth!

"This ......"

Fang Yu was a little stunned.

At this time, he noticed that Cao Tian was already quite close to the fire in the center of the earth.

Fang Yu came back to his senses, and there was some excitement in his eyes.

The fire from the center of the earth sent to the door, if he doesn't laugh, I'm afraid he will be thundered by the sky.

Fang Yu leaned down, his head facing the ground, floating in the water.

Then, he clenched his right fist, and bursts of golden true qi swirled from his right fist.

"Hopefully this punch won't destroy the whole lake. ”

Thinking so, Fang Yu threw a punch towards the ground!

"Boom!"

The originally calm surface of the lake suddenly erupted into bursts of water, one higher than the other!

Ye Shengxue, who was not far from the lake, changed his face and retreated again and again.

At this time, she felt the ground shake!

"What's going on down there?"

Ye Shengxue's face was solemn, and she pulled Ji Feng up and stepped back for a distance.

She was hesitant to tell her family to send someone to help.

But after some thought, she decided not to do it.

This matter involved the orderly and another organization, and Fang Yu was also involved, the situation was relatively chaotic, and the Ye family was really not suitable to intervene again.

"Teacher Ji, how long will it take for your companion to arrive?" Ye Shengxue looked at the weak Ji Feng and asked.

"It's almost there. Ji Feng, whose face was bloodless, replied.

......

"Wow...... What's going on!?Hurry up and take pictures! What a wonder of the world!"

The lake suddenly burst into a column of water, causing many students who were walking by the lake to exclaim.
