When the car drove past the waterfall again, Yun Haoran stopped the car.

On the way back, he was afraid that his sister would be too excited, so he suggested that he should drive the car.

"Sister, I want to go up and see this waterfall. He said.

Yunni looked at him puzzled: "Why?"

"Sister, don't you think it's strange? Why does an extinct volcano that has just died have a waterfall coming down from the top of the mountain? It should be a crater on it? Could it be that the crater above has become a lake in just a few hundred years? And there is a steady stream of water? Although I have heard of this phenomenon, I have never seen it with my own eyes, I am very curious, let's go up and have a look, how about it?"

Yun Haoran agitated.

Yun Ni thought about it, anyway, there is nothing to do today, so it is better to accompany this stinky boy to go up and have a look, and it will be regarded as a holiday trip.

Yun Haoran parked the car on the side of the road, and then the two sisters and brothers walked along a forest path together to the top of the mountain.

The whole Yuncheng City is located in the semi-plain area, so there are no hills and mountains around, only the Xishu Mountain in the western suburbs is a little closer to the urban area, and further away, there are only one or two small hills in the county below.

Therefore, citizens want to go out to feel the natural scenery on holidays, and do not want to run too far, then, the road is relatively close, in addition to some parks, amusement parks, botanical gardens, and classical relics in the city, there is only this Xishu Mountain in the western suburbs.

Yun Haoran and his sister walked all the way up, and they also met many citizens climbing the mountain.

After a short time, I reached the top of the mountain, and sure enough, I saw a small lake, embedded in the verdant trees.

Yun Haoran looked at the surface of this lake, and wondered even more: How deep can such a large water surface be? Why can a waterfall be formed all year round?

Yun Ni saw her brother staring at the water in a daze, so she asked strangely, "What's wrong?

"Sister, you said that such a large lake, how can there be a waterfall all year round? There must be a sufficient source of underground water, which is constantly replenished, but the lake surface of the crater is basically because of the depression formed during the eruption, and when the eruption stops extinguishing, due to the melting of rain and snow, the accumulation of water will gradually form, that is to say, at the bottom of the depression of the crater, it is unlikely that there will be an underground water source, so where does the water source of Xishu Mountain come from? And you can go directly to the top of the mountain, isn't that a bit of a strange thing?" Yun Haoran frowned, looking thoughtful.

Yun Ni also felt a little strange when she heard him say this, but she didn't study geology either, so she didn't know much about this knowledge, so she had to say: "If you want to study it, you can't just look at it like this, why don't you go back to school and ask your teachers, or ask for advice from experts in this field." ”

At this time, Yun Haoran stared at a forest on the other side of the lake, as if he had found something.

"Sister, let's go over there and have a look. He couldn't help but say, took Yunni's hand, and walked briskly in the direction of the woods.

It was a dense forest, those trees seemed to be very old, tall and stout, covering the sky, but, between the forests, there was always a fog, those fog slowly swirled in the forest, Yun Haoran noticed that they were always in a certain direction, slowly rotating, the speed of rotation, so slow that the human eye can hardly find it, but Yun Haoran, whose eyesight is already many times that of human eyesight, can be seen clearly.

Yun Haoran pulled Yun Ni and bypassed the stone path on the shore of the lake, Yun Ni was almost dragged forward by him, she thought that she was an athlete, but she couldn't keep up with the pace of this stinky boy?

This stinky boy has obviously changed a lot, why does the master say that he is not an awakened person?

Well, maybe, it's on the way to awakening, so the master can't be sure yet.

Thinking about it like this, Yun Ni's heart was a little relieved.

In fact, Yun Haoran still deliberately slowed down, if he hadn't pulled Yun Ni, he would have come to that forest long ago.

Finally stood outside the woods, close to the swirling mist.

Yun Haoran stopped, stared through it, and a looming figure was hidden in the trunk of an ancient tree, what is this? Could it be a tree demon?

"Sister, you hide here, don't come out casually, I'll go in and have a look. ”

Yun Haoran pulled Yun Ni behind a thick tree trunk and let her hide there.

Although Yunni didn't know why, she still nodded.

Yun Haoran turned around and walked towards the woods.

The thick fallen leaves on the ground made a creaking and cracking sound.

Yun Haoran's eyes stared at the trunk of the ancient tree he saw earlier, and at the same time, he turned on all his perceptual abilities, always paying attention to the movements around him, in case there were other hidden people besides the figure hidden in the trunk.

The voice in the trunk of the tree was motionless, as if it had blocked out even breathing.

Yun Haoran pretended not to know about his existence, and walked straight through the woods, towards the source of the mist.

These swirling fogs all came from a hole in front of them, which was very small, and it was impossible for a human body to get into it, and it was estimated that it was a little rabbit, a little squirrel, a little fox or something, so that they could get in.

Yun Haoran was not only strange about the source of these fogs, but also strange about why these fogs rotated so regularly in this woodland?

His footsteps slowly approached the hole.

In the wind behind him, there was a sudden sound of breaking the sky.

Sure enough, it came.

Yun Haoran's eyes can see 360 degrees without dead ends, so he can see clearly a silver blade behind him that is comparable to the speed of a bullet flying over.

With a flicker, he dodged the blade.

The blade clattered into the place where he had been standing, and it was stuck on a boulder, straight into it, and the handle of the blade was still trembling slightly, showing the strength of the wrist of the person who threw the blade over.

The blade missed, and Yun Haoran clearly heard the person behind him "Huh", it seemed very strange that the young man in front of him could dodge the sudden attack behind him so neatly.

Without waiting for Yun Haoran to turn around, a figure in the mist rose into the air and jumped out of the trunk of the ancient tree, and at the same time, his hands were claws, and he directly flew towards Yun Haoran viciously.

This flying figure disturbed the vortex of mist that was slowly rotating before, and when the mist dispersed and floated, a fierce sword of soul consciousness invisibly cut into Yun Haoran's mind at the same time.

Huh, this guy, it seems that his cultivation is okay, and he can use both body and soul attacks at the same time.

Yun Haoran pretended not to support it, and retreated again and again, while holding his forehead with his hand, making a painful appearance.

The other party thought that he had succeeded, snorted coldly, and stepped forward, his right hand was like an eagle's claw iron hook, and it buckled towards Yun Haoran's throat.

All of a sudden, he pinched this young man's throat!

It seems that this young man, that is, he is just a little faster, and his ability to deal with attacks is almost zero.

But in the next second, he regretted it!
