There is a lot of fog, this place is really a little weird, even with Lin Xuexin's cultivation, the divine sense can't talk about the depths.

It just feels as if there is an incredible presence in front of me.

"Impossible, if there is really such a terrifying existence, how can it covet these ten taels of Ziyao Copper Essence." Xiao Yu shook his head in his heart, and stepped into the fog with Lin Xuexin.

Lin Xuexin was cautious, and even took out the Yuqing Treasure Jian that she was carrying, and was on guard at any time.

Swish!

Xiao Yu's eyes were scorching, flashing with moving light, and the crystal clear Great Dao runes were constantly changing in his eyes.

"Barrier!"

He whispered to himself, but there was no fear on his face, according to the earth, at this time, he had already surpassed the innate realm, enough to absorb it.

"Roar!"

A low roar sounded in the distance, Xiao Yu and Lin Xuexin turned around at the same time, and there was a faint darkness there, as if there was a cave.

"How many miles does this fog pervade over a radius?" Xiao Yu asked softly.

"It's about ten miles or so, ordinary creatures don't get close to this place at all, I can't imagine it, and now there is something living in it, it's really surprising."

Lin Xuexin sighed and said.

"Let's split up and look for it, I'll go to the cave, you go ahead and look for it, and we'll meet at the entrance of the cave in a moment."

Xiao Yu's sudden opening surprised Lin Xuexin, but she was still full of vigilance against Xiao Yu, afraid that he would escape after obtaining the treasure.

Thinking of this, she hesitated for a moment.

"Even if you don't believe me, you have to believe in your mother!"

Xiao Yu suddenly looked back at her, his eyes were incomparably clear.

"This ...... Well, I'll trust you once. Lin Xuexin dodged Xiao Yuye's gaze for a moment, and finally nodded.

At this point, the two finally separated, Xiao Yu took five hundred steps forward and walked into the dark cave, while Lin Xuexin continued to walk forward.

Swish!

After Lin Xuexin left, Xiao Yu's eyes suddenly flashed with a burst of brilliance, and he could see things at night and walked into the cave.

The cave was pitch black and empty, making Xiao Yu almost doubt his judgment.

"Something is wrong, no flaw is the biggest flaw, how can there be nothing in such a cave." Xiao Yu's eyes suddenly lit up.

He lowered his head and dug into the ground with his hand a few times, and suddenly a black skeleton appeared on the ground.

"Sure enough." Xiao Yu muttered to himself.

But then he began to be surprised.

In this dark cave, it was densely packed with white bones, which was extremely terrifying, and I really didn't know how much killing it would take to achieve such a level.

"What the hell is it?" Xiao Yu finally began to be surprised, at this time, there were not only human corpses in the cave, but also demon beast bones.

The unknown existence seems to be not far away, and nothing can escape its poisonous hands.

This is, a gust of cold wind blew, making Xiao Yu's neck chill, and then the hair on his whole body counted down, as if something was approaching him.

"Who?"

Xiao Yu suddenly turned around and looked around, but he couldn't see anything, as if there was really a yin spirit in this small cave.

Phew!

A flame suddenly appeared in his hand, extremely scorching, as if it could scorch people's souls, extremely powerful, and the original gloomy atmosphere disappeared as soon as this fire came out.

The deeper he went, the number of bones became scarce, but the more strange it became, and the skeleton was extremely complete without the slightest damage.

"It's ......"

Suddenly, Xiao Yu's eyes lit up, and he stood there, only to see a skeleton appear there in the corner, sitting and lying, and there seemed to be something else beside it.

Xiao Yu walked over, but suddenly stopped, there was still handwriting written in blood on the ground, but at this time, it had dried up for a long time.

Hundreds, thousands of years!

He couldn't tell.

Xiao Yu lowered his head, looked at the bloody big characters, and sighed for a while.

"Mysterious monsters, devouring human flesh."

He became cautious and looked around vigilantly, could there really be an incredible existence.

"No way, my spiritual sense is very strong, if there really is such an existence, I can't not feel it." Xiao Yu shook his head, not convinced.

He lowered his head, picked up a cloth bag beside the skeleton, opened it gently, and suddenly a fire-like light radiated from the cloth bag.

"It's so full of vitality, it's the source!"

Xiao Yu sighed, during this time in the Lin Mansion, Xiao Yu had also seen the Pure Source a few times, and he couldn't be more familiar with such things.

He looked at it, and there was about a pound of yuan in it, and a booklet, I don't know what it was.

He took it out casually and looked at the pamphlet, which contained some nonsense.

"Eighty thousand catties of blood red source, a volume of the Changchun Sutra, a cold light sword, hereby to celebrate ......the New Year"

Xiao Yu glanced at it a few times, this seemed to be a birthday gift post, but the things in it were not quite the same as the post.

He only saw about a pound or so of blood red source, as for the Changchun Sutra and the Cold Light Sword, there was not even a shadow.

"I see that this is a loose cultivation, these things should have been obtained by robbery...... Well! ”

Before Xiao Yu's words fell, he suddenly felt that this post was a bit strange, and there seemed to be something inside.

He started directly, and with a click, the post was completely torn, and then he saw that in the middle of this post, there was a brocade woven of silk.

Vaguely, hundreds of ancient characters appeared on it, which was extremely cumbersome, Xiao Yu couldn't recognize them at all, only vaguely recognized a few words.

"Divine source, scriptures, curiosities, emperor!"

Xiao Yu suddenly gasped, he was not unfamiliar with the word emperor, all worlds were the same, he really couldn't imagine that such a thing still hid a secret about the emperor.

He directly put away the Jinpa, this thing will definitely be able to be used in the future.

At this time, his eyes were even hotter, and as soon as he walked here, he saw such a valuable thing, which was even more internal.

He walked step by step, and finally walked over.

At this time, after Xiao Yu entered another cave, the scene inside was suddenly very different from the outside world.

On the top, there are continuous stalactites, constantly dripping stalagmites, which are beautiful in an instant.

However, only people like Xiao Yu who can see things in the dark can see, and the others seem to feel that it is pitch black.

"Huh!"

Suddenly, a pair of eyes lit up, which made Xiao Yu startled, extremely red, as if he was a bloodthirsty demon, terrifying.

"Is this what they call a bloodthirsty demon?"

Xiao Yu exerted all his strength, and suddenly rose into the air and chased towards the red ray.
