Chapter 4251 Trapped, Cooperate

At this time, the fight between Mu Yun and Concubine Mo Xuan became increasingly fierce.

And Mu Yun also discovered that after Concubine Mo Xuan reached the first level of the Fighting Heaven Realm, she became several times more powerful, and her whole temperament seemed to have been greatly improved and transcended.

For a while, he couldn't take down Concubine Mo Xuan.

The two of them fought like this, becoming more and more violent.

Dozens of masters in this vast underground world are also taking action unscrupulously.

And gradually, cracks began to appear on the ground...

Before everyone noticed, cracks appeared everywhere in the entire underground world. In the end, these cracks spread and instantly surrounded them like a net. The sky collapsed and the bottom cracked.

The rumbling sounds kept ringing.

"Yun Mu!"

Wu Xinyao shouted loudly at this moment.

"Miss!"

Over there, the expressions of the warriors from the Heavenly Demon Sect also changed.

The fight between Mu Yun and Concubine Mo Xuan went deep.

At this time, the earth cracked and fell from the sky, wrapping up the two bodies and disappearing.

At this time, everyone can only exit the outside world along the way out.

"Damn it."

Wu Yuanhan also cursed lowly at this time.

Those falling boulders completely destroyed the underground world, and everything was gone.

The figures of Mu Yun and Concubine Mo Xuan could not be seen at all.

Wu Xinyao stepped forward and punched the stone.

However, a shocking discovery was made.

Shi Lei was motionless at this moment.

Wu Xinyao was stunned for a moment. After examining it carefully, her face changed and she said, "This is not an ordinary stone, it is a fire-refined Yuan Stone."

Fire-refined primeval stones are ordinary stones that are formed after being roasted by source fire.

This kind of fire-refined Yuan Stone, in terms of hardness, can't even do anything in the Dominion Realm.

"Damn it!"

Wu Xinyao looked at the Heavenly Demon Sect and hummed: "Now you are satisfied. Yun Mu is gone, and so is your lady. If they die, they will die together."

The Demon Xuan elder from Tianmo Sect had an ugly face.

Tianmo Sect is located in Tianyan Realm.

Everyone only knows that the young master of the Tianmo Sect, Mo Youlin, has outstanding talent and will succeed the sect master Mo Yunting in the future.

But in fact, Concubine Mo Xuan is more naturally evil than her brother Mo Youlin.

If the lady dies here...

Then he is dead!

But right now, the entire underground world is completely covered.

Can't get in!

Let alone talk about it.

What should I do?

Rumble...

A series of roars continued to sound at this time.

It seems that the inside is still collapsing.

At this time, the underground world is indeed collapsing.

As the collapse began, Mu Yun evaded directly towards the depths.

The same is true for Concubine Mo Xuan.

The two of them were running side by side, and they couldn't care less about who was attacking whom at this time.

But behind, the roof above and the ground began to collapse, and rocks fell.

Concubine Mo Xuan was accidentally hit by a stone, and a mouthful of blood spurted out, but the stone did not break.

This is the Falling Heaven Realm!

It is impossible for ordinary rocks to cause any injuries if they fall down.

It can only show that those stones are not simple.

Mu Yun was even more careful at this time.

The two fled with their lives.

Finally, it seemed that we came to the end of the underground world, a wall.

The stone wall is smooth and glows with a faint cyan light.

It seems like...

Thunder sky.

Again?

Mu Yun's eyes changed.

He had entered such a place before, but there was no way from heaven to earth.

Now, there is another!

What happened to the Thunder Emperor back then? How come there are places like this everywhere in the secret land.

But……

If you don't go in, you will be completely buried by the boulder.

Enter, how to get out?

Seeing the boulders approaching, Mu Yun had no time to think.

Enter!

With a buzzing sound, Mu Yun's figure disappeared in front of the sky.

When Concubine Mo Xuan saw this scene, her pretty face turned pale and she hurriedly followed.

Two figures disappeared into the underground world.

At this time, the underground world was also completely covered.

Behind the curtain.

At first glance, it is a space that has been opened up.

There are mountains, water, trees and flowers.

Very peaceful.

It's not like when Mu Yun entered before, there were thunder beasts everywhere.

At this moment, Mu Yun also took a breath.

Concubine Mo Xuan immediately swallowed a pill and digested it.

"Tell me, should I kill you now, or give you to that one first and then kill you?" Mu Yun looked at Concubine Mo Xuan at this time and snorted.

After hearing this, Concubine Mo Xuan immediately tightened her expression.

She was hit by a boulder just now, causing serious injuries. If Mu Yun tried his best to kill her... he might be able to do it.

"You can kill me now."

Concubine Mo Xuan said: "It's just that if you kill me now, you won't be able to get out of here. Wouldn't it mean that you will end up alone here?"

Hearing this, Mu Yun grinned mockingly.

"I'm not afraid of being alone. The worst I can do is practice here until I can leave this place!"

Concubine Mo Xuan's face turned cold.

"If you want to kill me, you can, but be prepared to kill a thousand enemies and lose eight hundred to yourself." Twenty-four dagger lights appeared around Concubine Mo Xuan again.

At this time, the situation between the two is delicate.

After a while, Mu Yun stood up and looked behind him.

This is the edge of the secret realm here, and a curtain falls from the sky.

Mu Yun stretched out his palm, and thunder exploded inside the curtain.

Not long after, Mu Yun turned around and returned.

"This place is surrounded by formations." Mu Yun said directly: "You can't get out."

"But it's not like I won't be able to get out for the rest of my life."

Concubine Mo Xuan looked at Mu Yun at this time, always cautious.

At this time, Mu Yun sat down, less than ten meters away from Concubine Mo Xuan.

Concubine Mo Xuan wore a black dress and sat sideways on the ground. Her face was slightly pale, but she looked somewhat charming out of thin air.

"She's pretty, but it would be a pity to kill her!"

Mu Yun looked at Concubine Mo Xuan and said, "I just checked the location of the boundary wall. The formation is very strong. With my current formation skills, I can't get out."

"However, by practicing in seclusion here, my boundary lines will be strengthened, and I will be able to leave one day."

"Kill you, I am indeed quite lonely by myself."

"However, you need to understand that if you kill me while keeping your life, you will never be able to get out on your own with your ignorance of battle tactics."

"There is no life-or-death feud between you and me. You wanted to steal my things, but I tricked you once. We are even!"

"Next here, I hope we can live in peace!"

The meaning of Mu Yun's words is very clear.

cooperate.

Concubine Mo Xuan looked at Mu Yun's handsome face and hummed, "I know."

"If you don't attack me, I won't attack you."

"So good!"

Mu Yun glanced ahead.

"To break the boundary formation, I need to practice for a long time and condense the boundary patterns. We need to have a general understanding of this place and know whether there are other dangers here, so that we can stay at ease."

Mu Yun looked at Concubine Mo Xuan and said, "Can you still leave?"

"Can!"

Concubine Mo Xuan struggled to stand up, panting slightly.

Mu Yun didn't help him either.

He won't show his kindness indiscriminately. What if he is tricked at this time?
