As soon as the sun reached its peak, the blazing divine light shone on the mist, causing the mist to ripple and begin to curl up like a living creature. However, it was not wiped out, but just rolled into a ball.
Li Yu frowned.
Under his full force, the temperature of the flaming sun's demon-killing divine light was so high that even black iron and fine gold could melt, but it was unable to do anything to the mist.
This mist seems to be neither spiritual energy nor demonic energy, nor any kind of alien energy in the world. It is more like a special substance, but it also possesses a weird spirituality.
Li Yu activated his sword intent, intending to kill him with the supreme sharpness contained in his sword intent.
The Bibo Sword Intention is extremely fast, capable of killing souls, and is extremely sharp, easily cutting the mass of matter in half.
but......
Not long after, the mass of matter stuck together and returned to its previous appearance.
Next, he used various methods such as flooding, burning, poisoning, etc. However, this mass of material was like a copper pea that could not be steamed, boiled, pounded, or fried.
No matter what method you use, you can't do anything about it.
However, without this thing causing trouble, the weasel never resurrected.
Li Yu didn't dare to be careless in the face of such strange things, but he also became interested in it and decided to go back and study it.
After thinking about it, Li Yu simply took out the Geng gold copper bottle.
With just a push of the button, a huge suction force suddenly emerged from the mouth of the Geng-gold copper bottle, which sucked the strange thing in. With quick eyesight and quick hands, he quickly corked the bottle.
The Geng gold copper bottle seems to be just an ordinary magic weapon, but in fact it has a great origin.
If it were an ordinary magic weapon, Li Yu would not be so careless.
However, based on his understanding of this thing, this thing was left by the Five Spirits Sanren. It can be combined with another Xinjin copper bottle and turned into a special secret treasure - Taiyuan Golden Gourd.
This thing is related to some of Wuling Sanren's plans and back-ups.
It's about a Yin God cultivator. Of course, this thing can't be simple.
The Geng Gold Copper Bottle did not disappoint him.
During Li Yu's observation, the strange thing inside turned around several times, trying to find some gaps, exits, etc. to escape, but after wandering for a long time, he could not find any flaws.
To be on the safe side, Li Yu's fingertips flashed with light, and he placed a forbidden seal on the Geng gold copper bottle before putting it away.
Then, Li Yu looked around and saw that the strange fog had not dissipated, so he continued to go deeper.
The weird weasel in Niujiao Mountain has been killed by him, so the question arises.
Why haven’t these mysterious fogs disappeared yet?
The answer is simple.
Maybe there is more than just one weasel, or there may be another reason for these strange fogs.
But maybe it was because Li Yu had already killed the weasel, so he never encountered any slaves again.
More than an hour later, Li Yu came to a cliff.
The terrain here is quite high, with rugged rocks, and the mist here seems to be thicker than in other places.
On the cliff, there is also a strange big tree growing on the side.
This big tree can be as thick as a dozen people hugging each other. The trunk is strong and straight, the roots are intertwined and firmly rooted in the rocks, and the branches and leaves are lush.
The whole big tree looked like it was blocking out the sky and the sun.
However, both the roots and trunk of this tree are a grayish gray color, and even the leaves are a strange gray-white color.
Threads of gray-white mist gradually seeped out from these leaves and gradually flowed to other areas.
Li Yu even saw that there was a tree hole above the big tree, and there was a faint fishy smell inside, which was almost the same as the smell of a weasel.
This is obviously the weasel's den just now!
"It turns out that the strange source of Niujiao Mountain is actually a tree!"
Li Yu was amazed, thinking that he might have found the strange truth about Niujiao Mountain.
A spiritual light flew out from his sleeves and turned into a sword light, clear green and green. It circled in the air, pulling out a long ray of light and smashing many branches, leaves and tree trunks.
The fragments scattered one after another, and most of them fell to the bottom of the cliff.
Seeing that the strange tree showed no reaction, in response to Li Yu's thoughts, the Green Snake Flying Sword turned softly and flew up and down, crushing the tree trunk inch by inch.
Even though the trunk of this tree is as solid as iron stone, it is no different from tofu under the spiritual weapon Green Snake.
In just a dozen breaths, a towering ancient tree was destroyed in Li Yu's hands.
He reached out and called back the Green Snake Flying Sword, and something wrapped in the sword light fell into his hand.
This is a dark green, almost black thing.
It looks like a spar or the heart of a tree. It is as thick as an arm and half a foot long.
Li Yu could detect that it contained a large amount of Yimu essence, but more of it was a majestic and evil vitality with a hint of strange aura.
There is also a gap in this piece of material. There are some fine tooth marks on the gap. Judging from the shape of the teeth marks, it is clearly left by the previous weasel.
"Could it be that this kind of thing is the culprit that caused the weasel to transform into a two-headed nightmare?!"
Guessing in his mind, Li Yu looked over it for a moment and found nothing unusual. He put it away and looked up to look around.
It was seen that after the tree was destroyed by him, the surrounding fog gradually became lighter. According to this trend, within a few hours, the entire Niujiao Mountain's fog will dissipate.
He escaped from the light and came to the cliff.
A tree does not become like this for no reason.
It must have been contaminated, or it became like this for some reasons. Li Yu had already vaguely guessed about this.
Under his urging, the Green Snake Flying Sword's sword light criss-crossed like lightning and flint, cutting through all the gravel shrubs along the tree roots.
After cutting through half of the cliff, Li Yu suddenly discovered that there was a strange cave hidden in the rock.
In this cave, there is a crack, which is more than half a foot long and the width of a palm. It is dark and blurry inside, and you can't see anything clearly, but there is only a cold and weird atmosphere coming out.
One of the thickest roots of this big tree penetrated into the crack in the cave.
"It is indeed a crack in the void..."
Li Yu's eyes were deep.
Weird things are not something that exists in this world.
It only appeared more than 7,000 years ago.
Since its emergence, this world has been plagued by strange intrusions.
After a fierce siege and extermination, some of the great cultivators in this world discovered these strange and strange things. The powers were strange, diverse, and terrifyingly polluting. Even the souls of the monks and even the Yin gods,
Even the soul can be easily contaminated.
And even if they are wiped out, there will still be many weird things popping up.
The reason is that the world barrier in this world has become a little fragile for some reason. It is often torn apart by force, and then many void cracks appear.
Just like the strange girl Li Yu killed before, she was contaminated by the strange white jade hairpin.
And some of them are strange, because they are contaminated by the strange power coming from some void cracks that connect to the outside world.
The catastrophe of the strange demons a few months later is actually related to these cracks in the void.
Li Yu had no other way to deal with the crack in the void in front of him for the time being, and he did not try to detect it with his spiritual thoughts because of his cleverness.
This thing is quite dangerous. Who knows what is hidden on the other side?
If he really provokes something terrible, he won't be able to resist it.
So I simply pulled out the tree root, found gravel to block the cave, and then left the place.
