As soon as the sun reached the sun, the blazing divine light shone on the mist, and the mist rippled, and began to curl up like a living thing, but it was not extinguished, but only clumped.

Li Yu frowned.

Under his full urging, the temperature of this Burning Sun Demon Slayer Divine Light was extremely high, and even the dark iron essence gold could melt, and he couldn't help this mist.

This mist seems to be neither spiritual energy, nor demonic energy, nor any kind of alien energy in this world, but more like a special substance, but at the same time it has a strange spirituality.

Li Yu urged the sword intent, wanting to use the supreme edge contained in the sword intent to kill it.

Bibo Sword Intent is extremely fast, capable of slashing divine souls, and extremely sharp, easily cutting this mass of material in half.

But......

It didn't take long for the mass to fit together and return to its original form.

Next, he used various methods such as flooding, burning, and poisoning, but this mass of material was like a copper pea that could not be steamed, cooked, pounded, or fried.

No matter what method is used, it can't be helped.

However, without this thing, the weasel never came back to life.

In the face of this strange thing, Li Yu didn't dare to be careless, but he was also interested in this thing and decided to go back and study it.

After thinking about it, Li Yu simply took out the Gengjin copper bottle.

With just one urge, a huge suction force suddenly appeared on the mouth of the heptane gold copper bottle, which contained this strange object, and he quickly plugged the cork.

The Gengjin copper bottle seems to be just an ordinary magic weapon, but in fact it has a great origin.

If it was an ordinary magic weapon, Li Yu would not be so careless.

However, according to his understanding of this thing, this thing was left by the Wulingsan people, and it was combined with the other Xinjin copper bottles, which could be turned into a special secret treasure - Taiyuan Golden Hu.

This thing is related to some of the plans and backhands of the Wulingsan people.

It's about a Yin God Great Cultivator, and this thing can't be simple.

The heptane copper bottle did not disappoint him.

In Li Yu's observation, the strange object inside turned around a few times, and he wanted to find some gaps, exits, etc. to escape, but after wandering around for a long time, he couldn't find any flaws.

To be on the safe side, Li Yu's fingertips flickered, and he put a layer of prohibition seal on the Gengjin copper bottle, and then put it away.

Then, Li Yu looked around, and saw that the treacherous fog had not dissipated, and he continued to go deeper.

The weird weasel of Oxhorn Mountain has been killed by him, so here's the problem.

Why hasn't the fog gone away?

The answer is simple.

Maybe there's not just one weasel, or maybe there's another reason for the weirdness.

But maybe it was because Li Yu had already killed the weasel, and after that, he never encountered any tricks again.

More than an hour later, Li Yu came to the edge of a cliff.

It's quite high, it's rocky, and the fog seems to be thicker than anywhere else.

On the cliff face, there is also a strange tree growing on the side.

The tree was as thick as a dozen people hugging, its trunk was vigorous and straight, its roots were intertwined, firmly rooted in the rocks, and its branches and leaves were lush.

The whole tree looks like it's almost overshadowing the sky.

But both the roots and the trunk of the tree had a grey lime colour, and even the leaves had a strange greyish white.

Wisps of grayish-white mist seep out of these leaves and flow to other areas.

Li Yu even saw that there was a tree hole above the big tree, and there was a faint smell of fishy smell coming from it, which was almost the same as the smell on the weasel.

This is clearly the weasel's den just now!

"It turns out that the strange source of this Niujiao Mountain is actually a tree!"

Li Yu was amazed, thinking that he might have found the strange truth of this Niujiao Mountain.

A spiritual light flew out of his sleeve robe, turning into sword light, green and clear, and as soon as it circled in the air, it pulled out a long ray of light, and smashed many branches and leaves and tree trunks.

Debris was scattered and scattered, and most of them fell to the bottom of the cliff.

Seeing that this strange tree did not react, in response to Li Yu's thoughts, the green snake flying sword turned softly, flying up and down, and smashed the trunk inch by inch.

Rao is the trunk of this tree is as solid as stone, and under the spirit weapon green snake, it is no different from tofu.

However, after more than a dozen breaths, a towering ancient tree was destroyed in Li Yu's hands.

He reached out and summoned the green snake flying sword, and the sword light wrapped in something fell into his hand.

It's a dark green, almost black thing.

Like a spar, like a tree heart, the thickness of the arm, half a foot long.

Li Yu could perceive that it contained a large amount of Yimu essence, but more of it was a majestic and evil vitality, with a trace of weird aura.

In this section, there is also a gap, on which are some fine tooth marks, looking at the shape of the tooth marks, it is clear that they were left by the previous weasel.

"Could it be that this is the culprit that created the weasel to transform into a two-headed nightmare?!"

Guessing in his heart, he looked over and over for a moment, and didn't see anything abnormal, Li Yu put it away and looked up.

I saw that after the tree was destroyed by him, the surrounding fog gradually faded a little, and according to this trend, within a few hours, the fog of the entire Niujiao Mountain would dissipate.

He escaped and came to the cliff.

A tree doesn't become like this for no reason.

It must have been polluted by something, or some reason why it became like this, Li Yu already had a faint guess in his heart.

Under his urging, the sword light crisscrossed like lightning and flint, cutting through all those gravel shrubs along the roots of the tree.

After cutting through the small half of the cliff, Li Yu found that there was a strange cave hidden in the mountain rock.

In this cave, there is a crack, more than half a foot long, the width of the palm, the inside is dark and blurry, and it is impossible to see things clearly, but there is a trace of cold and strange aura outside.

One of the thickest roots of the great tree poked into the crack in the cave.

"Sure enough, it's a void rift......

Li Yu's eyes were deep.

Weird is not something from this world.

It only came out more than 7,000 years ago.

Ever since its appearance, this world has been plagued by strange things.

After a fierce encirclement and extermination, some of the overhaul powers in this realm discovered these strange and strange things, the power is strange, diverse, and terrifyingly polluting, even the monk's divine soul and even the Yin God and Yuan Shen can be easily polluted.

And even if it is destroyed, there will still be many strange things that will continue to emerge.

The reason for this is that the world barriers in this realm have become a little fragile for some reason, and some are often torn apart by power, and then many void cracks appear.

It's like the weird girl killed by Li Yu before, which was polluted by the tricky white jade hairpin.

And some of the weirdness was polluted by the strange power from some void cracks that connected to the outside of the domain.

The Demon Tribulation a few months later is actually not unrelated to these void cracks.

Li Yu had no other way to deal with the void crack in front of him for the time being, let alone use his divine thoughts to probe it.

This thing is quite dangerous, and who knows what's hiding on the other side?

If something terrible really provoked, he couldn't resist it.

So he simply pulled out the root, found gravel to block the cave, and left the place.
