Chapter 4256: Trapped, cooperate.

At this time, Mu Yun and Mo Xuan concubine fought more and more fiercely.

And Mu Yun also discovered that after the Concubine Demon Xuan reached the First Stage of Slashing Heaven Realm, she was several times stronger, and her entire temperament seemed to be greatly improved and leaped.

For a while, he couldn't take the Demon Xuanfei.

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

Dozens of Domination Realms are also unscrupulous shots in this vast underground world.

And gradually, the ground began to crack...

Before everyone noticed, cracks appeared everywhere in the entire underground world, and in the end, these cracks spread out and instantly surrounded as a net, collapsed in the sky and cracked underneath.

The rumbling voice kept ringing.

"Yun Mu!"

Wu Xinyao shouted loudly at the moment.

"Miss!"

Over there, the martial artist of the Sky Demon Sect also changed his expression.

Mu Yun and Mo Xuan concubine fought each other towards the depths.

At this time, the earth broke and fell from the sky, and the bodies of the two people were wrapped and disappeared.

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

"Damn it."

Wu Yuanhan also cursed in a low voice at this time.

Those falling boulders completely smashed the underground world, and everything disappeared.

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

Wu Xinyao stepped forward at this time and slammed a punch between the stone studs.

However, a shocking scene was discovered.

Shi Dui remained motionless at this moment.

Wu Xinyao was taken aback, and under closer inspection, her expression changed, and said, "This is not an ordinary stone, it is a fire-refined primordial stone."

The fire-refined primordial stone is an ordinary stone that is formed after being roasted by the source fire.

This kind of fire refines the primordial stone, in terms of the degree of hardness, it can't do anything to dominate the realm.

"Damn it!"

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

The Demon Xuan elder of the Sky Demon Sect had an ugly face.

Heavenly Demon Sect is located in the realm of Heavenly Demons.

Everyone only knows that the young master of the Sky Demon Sect, Demon Youlin, has outstanding talents and will take over the task of Sect Master Demon Yunting in the future.

But in fact, Concubine Demon Xuan is more talented and enchanting than her brother Demon 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.

How can this be good?

Rumbling...

The roaring sound continued at this time.

It seems that the interior is still collapsing.

At this time, the underground world is indeed constantly collapsing.

As the collapse began, Mu Yun was directly hiding in the depths.

The same is true for Concubine Mo Xuan.

The two went hand in hand, and at this time they couldn't care about who shot at whom.

But behind, the top of the sky and the ground all began to collapse, falling rocks.

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

This is the Heaven-cutting Realm!

It is impossible for ordinary rocks to cause any injuries.

It can only be explained that those stones are not simple.

Mu Yun was even more careful at this time.

The two ran away desperately.

In the end, it seemed to come to the end of the underground world, a wall.

The stone wall is smooth, glowing with a faint cyan light.

Seems to be...

The thunder canopy.

Again?

Mu Yun's eyes changed.

He had entered such a place before, but there was no way into the sky and nowhere.

Now there are again!

What happened to the Lei Di back then, how are there such places everywhere in the secret area.

but……

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

Enter, how to get out?

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

Come in!

Buzzing fame sounded, and Mu Yun's figure disappeared in front of the sky.

Concubine Mo Xuan turned pale when she saw this scene, and hurriedly followed.

Two figures disappeared into the underground world.

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

Behind the sky.

At a glance, it was a space opened up.

There are mountains, waters, trees and flowers.

Very peaceful.

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

At this moment, Mu Yun also took a breath.

Mo Xuan Fei immediately swallowed a pill and digested it.

"You said, did I kill you now, or should I give you to that first and then kill you?" Mu Yun looked at Concubine Demon Xuan and snorted.

Hearing this, Concubine Mo Xuan's face immediately tightened.

She was hit by a huge boulder just now, causing her to be seriously injured. If Mu Yun tried his best to kill her... it might be possible.

"You can kill me now."

Concubine Mo Xuan said: "It's just that if you kill me now and you can't get out here by yourself, wouldn't it be lonely to stay here forever?"

Hearing this, Mu Yun grinned with a sneer.

"I am not afraid of loneliness, the big deal is to practice here until I can leave this place!"

Concubine Mo Xuan's face was cold.

"You want to kill me, yes, but be prepared to kill one thousand and harm yourself eight hundred." Mo Xuan concubine's body, with twenty-four daggers, appeared again.

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

Not long after, Mu Yun got up and looked behind him.

Here is the edge of the secret realm here, a curtain descending from the sky.

Mu Yun stuck out his palm, and within the curtain, thunder broke out.

Not long after, Mu Yun turned back.

"Here is surrounded by formations." Mu Yun said directly: "Can't get out."

"But, it's not that I can't get out all 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 Demon Xuan.

Concubine Mo Xuan wore a black dress and sat on the ground with a pale face, but she looked a bit charming and moving out of thin air.

"The appearance is good, it's a pity to kill the monster!"

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

"However, when I practice in retreat here, my boundary lines are strengthened, and one day I can go out."

"Kill you, I am really alone."

"But, you need to understand, to save your life, if you kill me, with a posture that you don't know anything about the formation, you will never go out by yourself."

"Between you and me, there is no feud, you want to grab my things, I shame you once, we are even!"

"Next here, I hope we can get along in peace!"

Mu Yun's words are very clear.

Cooperation.

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

"If you don't do it to me, I won't do it to you."

"It's so good!"

Mu Yun glanced forward.

"To break the boundary formation, it takes me a long time to practice and condense the boundary lines. We must have a general understanding of this and know whether there are other dangers here before we can rest assured."

Mu Yun looked at Concubine Demon Xuan and said, "Can you still go?"

"can!"

Concubine Mo Xuan struggled to stand up, panting slightly.

Mu Yun didn't help either.

He doesn't spit out kindness, what if he gets overcast at this time?
