It was at the outskirts of the Tianyuan mountain range at this moment.

There was a group of people slowly moving forward on a relatively flat and open terrain.

The person in the lead was the Great Elder of the Ancient Witch Sect, Duan Kun.

Duan Kun's face was gaunt, and his pair of triangular eyes were as cold and gloomy as a venomous snake. With a single glance, one could tell that he was not a kind person.

A few days ago, Feng Biao had asked a disciple to go back and seek help. After the disciple went back and reported to him, Duan Kun felt that something was not right.

He knew very well about the Tianyuan mountain range.

Thirty years ago, his father had come here to train. There was definitely only a small stream in Qingyan Valley in the past.

He used to rest by the stream often.

If the disciple said that the stream had dried up, he would have believed it. But to say that a huge mountain had appeared, this was absolutely impossible.

If this disciple was telling the truth, then Feng Biao would definitely be in danger!

However, how could Feng Biao, the most capable general of Ancient Witch Sect 's Great Elder, die without any reason? If this news were to spread, he would definitely be ridiculed. This was something that he definitely could not tolerate.

Hence, he personally led the team and even called his good friend, Chen Wei, to come along.

Chen Wei was also an elder of the Ancient Witch Sect. He was only a guest elder, but his strength was not to be underestimated. He was slightly weaker than Duan Kun, who was at the fourth level of the Dharma Realm. He was at the third level of that realm.

"A high mountain has really appeared?" Chen Wei looked at Mount God of Heaven in front of him with a surprised expression.

Duan Kun took out a map and looked at it repeatedly. He also kept looking at where they came from.

"Strange, it's too strange. There's something wrong with this mountain!" Duan Kun said with a serious expression.

He glanced at Chen Wei and continued, "I'm afraid that Yu Sisi and Feng Biao are both caught in it. They're probably doomed!"

Chen Wei's expression changed as he thought to himself.

"Do you still want to go and check?" Chen Wei said slowly.

Duan Kun's sinister eyes swayed left and right as if he was hesitating.

Actually, he didn't care about whether Feng Biao was dead or alive. He wanted to know Yu Sisi's whereabouts more. It would be best if he could find her.

It was also because of this that he brought so many people here to search around the mountain thoroughly.

After all, as long as he could capture Yu Sisi, he would be able to obtain the key to that secret treasure.

Who would have thought that an unknown small family was actually one of the descendants of an expert from a mystic realm.

If he had known that he would encounter this mystic realm, he would not sacrificed the entire Yu family. They are the key of the mystic realm. 

When he learned that there was a girl who was still alive, he was naturally extremely excited.

But he was busy at that time, so he could only let Feng Biao handle the matter.

He didn't expect to encounter such a strange thing.

Now, he knew that there were treasures in the mystic realm. However, without the key, he couldn't get them.

"Duan Kun, you have to understand that this is only the foot of the mountain. it was not too late to leave." Chen Wei narrowed his eyes.

Duan Kun glanced at Chen Wei and said coldly, "This mountain had never appeared for so many years, and it suddenly appeared now. It can't be fallen from the sky!"

Chen Wei nodded and said, "Yes, Tianyuan mountain range is extremely complicated. Not only are there magical beasts, but there are also peerless masters hidden here. This mountain that suddenly appeared must have existed before. But it was blocked by some enchantments in the past, now that the enchantments have been removed, and this mountain naturally appears. Therefore, something must have happened here!"

Did anything happen?

Duan Kun thought of the huge black shadow that suddenly appeared a few days ago.

"I remember that the huge shadow that appeared a few days ago appeared in this area," Chen Wei said.

Duan Kun and Chen Wei looked at each other.

It seemed that they were thinking of the same thing.

Duan Kun nodded slightly. Chen Wei knew that Duan Kun was very familiar with this area. When he saw that Duan Kun had confirmed it, he looked at Mount God of Heaven again. When he was recalling the scene that day, his pupils constricted slightly.

Even now, when he was recalling the scene that night, he could still feel an incomparable palpitation in his heart.

"That should be this place. Two peerless experts once fought here. Duan Kun, you can't go to this mountain range. Think about it. Just the pressure emitted by that huge black shadow that covered the clouds and the moon was enough to make us lie on the ground and not able to move. How powerful must the expert that fought with that black shadow be!"

Chen Wei hurriedly explained.

Duan Kun also gradually began to think about it, and his eyelids couldn't help but twitch.

"This... could it be the Spirit Saint Realm?" Duan Kun's voice at this time was slightly trembling.

The Spirit Saint Realm!

The most supreme existence in the Divine Ao Mainland!

It actually appeared in Yanzhou?

Moreover, it was in this Tianyuan mountain range?

This would probably be something that could be bragged about.

Chen Wei nodded very seriously.

"Great Elder, look, what is that?"

At this moment, the top of Mount God of Heaven was covered with black clouds. Countless spiritual energies were crazily gathering into the clouds like a tidal wave. At the same time, countless red thunderbolts were striking from the dark clouds.

The thunderbolts crazily struck down toward the top of the mountain. One after another, they finally gathered in one place, as if they were preparing for the last attack.

Such a terrifying scene made everyone who was watching dumbstruck.

"What is this?"

"How can there be such a terrifying power of lightning, yet we don't feel any of the aftershocks!" Chen Wei said with a solemn gaze.

Although this black cloud and red lightning weren't as tyrannical as the giant shadow that obscured the moon that night, from the scene, it was still extremely terrifying.

Perhaps what happened that day was because it was during night time, so everyone could only rely on their senses and could not detect it with the naked eye. Only some elders who had stepped into the Dharma Realm could detect the silhouette of the black shadow.

However, whether it was the shadow that obscured the moon that day or the terrifying thunderclouds that appeared on the mountaintop now, none of them were able to come into contact with the power.

However, one of the biggest differences between now and that day was that the invincible and overbearing spiritual power pressure that day had suppressed all of them until they were unable to move.

And now, facing such a situation, logically speaking, they should be able to sense the aura.

And they might even be affected!

But there was nothing.

They couldn't feel anything.

But this made Duan Kun and Chen Wei even more terrified.

This reclusive almighty was actually able to seal off space, preventing the aura from spreading out.

What kind of strength was this!

What kind of powerful realm was this!

Just what kind of battle was the master of this mountain engaging in! 

"We can't go there! Duan Kun, even if the person you're looking for is up there, I'm afraid that all of them have already been shattered by this heavenly tribulation-like terrifying thundercloud!" Chen Wei's eyes were in a daze as he muttered to himself.

Duan Kun's hands trembled slightly as he silently wiped off the cold sweat on his forehead. Then, he turned around and said with a slightly hoarse voice, "Go, hurry up and leave now!

In the past, the central area of the Tianyuan mountain range was a dangerous area. Now, even the outer area is filled with danger. Hurry up and leave!"

Duan Kun frantically circulated the spiritual energy in his body and ran out without turning his head back.

As for those mystic realm treasures?

They were not as important as his own life.

Just like that, a group of people rushed over aggressively, but now they left the periphery of the Tianyuan mountain range as if they were running for their lives.
