The rumbling sound in the depths of the cave grew stronger, accompanied by a series of heart-stopping roars, as if some ancient creature was awakening..

Lu Chen and Chu You looked at each other and saw a trace of seriousness in each other's eyes..

The two of them had been fighting fiercely in this cave for an entire day and night, but no demon beasts had appeared in this cave. Why did they suddenly make such a huge commotion?

Lu Chen's expression was solemn. His eyes were fixed on the depths of the darkness. He held the meteorite brick tightly in his hand, ready to deal with the imminent crisis at any time..

Chu You also stood up. He stretched his hand to his waist and lifted the dagger..

"Looks like there's something big hiding in this nest..

Chu You's lips curled into a smile..

After she dual cultivated with Lu Chen, she directly broke through to a minor realm. Her strength increased greatly, and her confidence also increased..

"Perhaps this is a great opportunity. It is the only secret realm that the Blue Cloud Sect has preserved since ancient times. Since we are lucky enough to find it, why not explore it in depth?.

”

Lu Chen frowned and thought to himself.

As soon as he entered the nest, he encountered an ancient third-tier demonic beast. If Chu You had not crushed the Blackthorn Demonic Gorilla at the peak of the Golden Core Realm, it would have been a bitter battle..

Now, his strength had only increased to the peak of the Foundation Establishment stage and had not yet consolidated his advancement. If he encountered an ancient fourth-tier demonic beast, he might not even have the chance to escape..

Four days till the end of the mystery?.

.

.

While there was still time, he would find an opportunity to ruthlessly pluck Chu You's nourishment. After plundering her cultivation, he would break through his own cultivation to the Golden Core stage. It would be safer to explore this ancient demonic beast nest again..

Thinking of this, Lu Chen said," Chu You, don't be rash..

The commotion just now was very strange. I'm afraid it's dangerous and unpredictable. We can't go deep rashly..

”

Chu You snorted coldly," If you're afraid, just wait here. Sister will go by herself.".

Then she walked toward the direction of the voice..

Lu Chen gritted his teeth..

.

.

There were still abnormal movements in the demon beast nest. There must be opportunities hidden inside. If Chu You took it away, he would not be her opponent anymore..

If Chu You did not take it away and was instead harmed by demonic beasts, then wouldn't it be a waste of this excellent cauldron?.

No, he had to keep up..

As the two of them went deeper and deeper, the aura in the cave became more and more suppressed, but the surroundings became brighter and brighter. The stone walls flickered with a strange light..

Chu You carefully scouted the way ahead, holding the dagger tightly in his hand..

"Lu Chen, hide behind my sister. Don't drag me down..

Chu You whispered..

Although Lu Chen was unhappy, he could not flare up. He just silently observed the surrounding environment..

Suddenly, a huge stone door appeared in front of them. Strange runes and patterns were carved on the door..

Chu You stopped and carefully observed the stone door." This seems to be some kind of array seal..

”

Lu Chen walked forward and looked at the complicated runes on the stone door. He frowned and muttered to himself,

This array formation seal is so complex and obscure, it seems that it is not easy to break it..

Chu You stared at the stone door for a moment. The corners of his mouth curled up slightly." So that's how it is.".

”

Her hands quickly formed seals, her slender fingers moved, and she chanted. The spiritual energy in her body surged into her fingers..

Then, he slammed his palm on the stone door. Spiritual energy surged out like a tide and slowly flowed into the runes on the stone door along a strange trajectory..

：.

The runes that were originally dim began to emit a soft and mysterious light under the infusion of spiritual energy. They interweaved with each other and formed a beautiful light curtain!

After a while, a crisp crack was heard as the stone door slowly opened..

Lu Chen looked at Chu You's back and was surprised..

I can't believe she knows so much..

The moment the stone door opened, a powerful air current suddenly gushed out!

"Huff!"

The two of them were forced back repeatedly. Before they could stand firm, a black shadow flew out from the door!

Looking closely, it was actually a huge python. Its scales flickered with a cold light, its eyes were like burning red flames, and its tongue hissed..

" Be careful, it's a demonic beast!"

Lu Chen and Chu You were both shocked. They quickly adjusted their bodies and prepared to deal with this sudden crisis..

The python twisted its thick body and occupied most of the space in an instant. It opened its bloody mouth and a fishy wind blew towards it..

Chu You reacted very quickly. He stabbed the dagger in his hand directly towards the python's eyes..

Unexpectedly, the python tilted its head and avoided this attack. At the same time, its tail swept over, bringing with it a whistling sound..

Chu You did not panic at all. Her beautiful eyes narrowed slightly and she directly cast Shadow Shield. A purple light appeared on her body and she disappeared from where she was..

In the next moment, she appeared behind the python. She waved the dagger in her hand fiercely, and a powerful spiritual light flashed past, directly slashing at the python's seven-inch position..

The python's body was pierced in an instant. Its huge body trembled violently for a few times before it fell heavily to the ground and no longer moved..

Just as Chu You pulled out the dagger, the python's body actually began to emit waves of demonic energy..

Lu Chen walked forward and frowned as he looked at the python corpse..

Its body was filled with a dense demonic aura, but its flesh and blood were gradually disappearing in a strange way. Most of its body was gone..

queer.

.

.

This feels like the Death Resurrection Technique..

.

.

Thinking of this, Lu Chen quickly asked with his spiritual awareness,"Old man.".

.

.

Master, what's going on with this demonic beast?"

Su Li replied in Lu Chen's consciousness,"This is an ancient second-tier demon beast, a leopard python.".

As for why it disappeared like this, I'm not too sure..

”

"But it looks like some form of supply..

Perhaps the beast exists to power something more powerful deep in the cave..

”

Lu Chen frowned. If that was the case, then the things in the depths of the cave would be extremely terrifying..

"Hiss!"

Before they could understand, there was a strange sound from around them..

Lu Chen and Chu You looked around vigilantly. They saw more leopard pythons slowly swimming out of the stone door and surrounding them!
