When sunlight hits the earth's surface, the surface temperature rises, and the air on the surface expands lightly and rises due to heat. When the hot air rises, the cold air at a low temperature flows in laterally, and the rising air cools and becomes heavier and falls, and the air heats up to rise due to the high surface temperature, and the flow of this air generates wind.

Alternatively, when the accumulated water vapor or clouds form water, the volume decreases, and the surrounding water vapor comes to replenish it, and wind can also be formed.

It's just that......

It was surrounded by endless mountains, and the sky above was so gray that even the top of the cave could not be seen.

It's like chaos, in the mountains of this ocean blue hole, let alone any sunshine.

It's just that there is this faint dark projection, so that Mu Chen and Song Qi can barely see the surrounding environment and landform.

However, if they want to travel through this mountain range, Mu Chen and Song Qi still have to use the detection light of the 'Thor' mecha.

There is no ambient temperature difference, even the spiritual power of heaven and earth contained in the surrounding air is exactly the same.

In all kinds of environments, Mu Chen can conclude that it is impossible to form such a natural and gentle breeze in this mountain range.

But now this breeze ......

There must be treasures around.

When the breeze comes, there will be a vision.

......

Searching for this breeze direction, Mu Chen and Song Qi also deviated from their original direction for the first time in this mountain range.

However, in order to prevent themselves from finding the treasure land by then, but still lost their way in this mountain range, Mu Chen and Song Qi also used all the available environments around them - dead wood, yellow grass, etc., to make a simple sign at the place where they deviated from the direction.

At the same time, he also used the nameless sword to carve an arrow on its ground, indicating the direction in which the two should have walked.

Following the direction of the breeze, in order not to confuse the route, Mu Chen and Song Qi also carefully perceived the precise course of the breeze for a long time in the same place, and this was the place where the breeze was blowing.

On the way, Mu Chen and Song Qi also tried their best to walk in a straight line, also in case they would not be able to find the mark they had made at that time.

In this way, Mu Chen and Song Qi have also been gone for a long time......

......

"Wow! this ......"

Looking at the lake in front of him, Song Qi was also speechless in surprise.

"Is this really in the middle of this desolate mountain range?"

After walking through the mountain range for a long time, Mu Chen and Song Qi also came to a huge boulder that was different from other peaks.

Actually, to say that this is a boulder is not so accurate.

Because Mu Chen and Song Qi had never seen such a huge stone.

Far beyond the surrounding peaks, this boulder was so abruptly blocked in front of Mu Chen and Song Qi.

But......

Such a strange environment, then there must be a strange chance.

Although the boulder was smooth and towering, with the efforts of Mu Chen and Song Qi, it took a lot of effort to finally step on the boulder.

Different from the desolate peaks around them, Mu Chen and Song Qi finally climbed this boulder, and what they saw was actually a huge clear lake!

The breeze floats and ripples on the calm surface of the lake.

Mu Chen and Song Qi couldn't have imagined that in such a mountain range, there was such a beautiful scenery!

The boulder is not only huge, but also very wide, as you can see from the lake that sits on top of the boulder.

There are a few aquatic plants at the bottom of the lake, and they are slowly shaking.

The only fly in the ointment is that there are no small fish and shrimp.

Standing on the side of this lake, Mu Chen and Song Qi couldn't see the full appearance of this lake at all, Mu Chen and Song Qi also preliminarily estimated the center of the lake in front of them, but the two still didn't see it.

In addition to being shocked, Mu Chen and Song Qi also slowly walked around the lake, trying to see if they could find a location where they could observe the entire appearance of the lake.

As for swimming directly into this lake, Mu Chen and Song Qi didn't dare to think about it.

First, neither of them is good at water, and they come here because it is always a blue hole in the ocean, and no one can tell whether this seemingly calm lake will hide something boring.

After walking along the lake for about a few hundred meters, Mu Chen and Song Qi finally found a location, and there were actually stone stairs that slowly extended to the center of the lake!

"And the road!

Is it directly in the middle of the lake? I just don't know if Ann is safe. ”

Jogging in small steps came to the beginning of the stone staircase, looking at the stone staircase that continued to extend step by step until it reached the center of the lake, Mu Chen and Song Qi also wanted to go up to find out, but they were worried about what kind of trap this stone staircase would have.

"If you don't enter the tiger's den, you can get the tiger!

Besides, this is not sure to be the tiger's den, anyway, we have not gambled many times along the way, right? ”

After pondering and wandering around the lake for a long time, Mu Chen finally opened his mouth to discuss with Song Qi.

Mu Chen, finally couldn't help the curiosity in his heart, and wanted to step into this stone staircase.

After all, in this desolate mountain range, there is such a beautiful scenery, and its intention is also extremely obvious.

If there are no treasures here, then where are they?

As for if there was really any trap, Mu Chen also asked himself that he was now able to react in a hurry and bring himself and Song Qi into the lake with the 'Holy Fire'-Ice Crystal Fusion.

Therefore, after thinking about it for a long time, Mu Chen finally told Song Qi his intentions.

"Hmm...... Well, anyway, such a beautiful scenery here should also be a hiding place for treasures, and it is estimated that we can only really see the face of this lake when we enter the center of this lake, right?"

Song Qi and Mu Chen seemed to think the same, and after Mu Chen put forward his intentions, Song Qi could only think about it briefly, and nodded slightly in agreement.

Next, it's time to step down the stone staircase to whether there is a problem or not.

In terms of luck, although Mu Chen is not good, Mu Chen still did not miss the various bets in this ocean blue hole!

This time, Mu Chen also believes in his choice!

......

As Mu Chen and Song Qi slowly stepped into the stone steps, the surrounding lake actually began to rise slowly, like a water curtain, covering the surroundings of Mu Chen and Song Qi, with the advance of Mu Chen and Song Qi, and stood still with the stop of Mu Chen and Song Qi.

In this way, under such a curtain of water like a beautiful scenery in the sky, Mu Chen and Song Qi also slowly walked to the center of the lake.

The surrounding water curtain is like a fountain that flushes out the water curtain, and it is quite rhythmic when it is raised.

Marveling at everything on the lake, Mu Chen and Song Qi also looked around carefully.

Looking around from where Mu Chen and Song Qi are now, no more, no less, just enough to see the whole picture of this huge boulder lake.

Looking into the distance, I just saw that the lake on the edge was as bright as a mirror, and the breeze blew on the blue surface of the lake, causing slight ripples, and the wind jumped onto the lake with the thin waves.

I saw that the surface of the lake was crystal clear, like a crystal stone; At this time, the lake is very calm, like a bright mirror; The surface of the lake is clear and green, like a flawless jade.

In the gap that Mu Chen and Song Qi didn't notice, the surrounding water curtain became more lively again.

Bursts of up, up and down, like children having fun, happy.

"Snort~"

Finally, with the rise of the Zhou water curtain, the water curtain finally popped out of the lake, and it actually became a pavilion framework built around Mu Chen and Song Qi.

The water curtain swam, but under a mysterious force that Mu Chen and Song Qi didn't know, it slowly turned into icicles.

The continuous water curtains surrounded Mu Chen and Song Qi, and the water lines were like supports, and when these water curtains were in a special position, they suddenly condensed into ice.

I don't know what the purpose of these water curtains is, I don't know what it means for the lake, and what kind of impact it has on Mu Chen and Song Qi themselves.

However, Mu Chen and Song Qi were very interested in the stone staircase in the middle of the lake.

Each new curtain of water condensed into ice, and was completed by the construction of a part of the pavilion-like ice and snow buildings around Muchen.

Mu Chen and Song Qi also did not feel any dangerous breath, so in the face of this sudden, or unclear change, they did not retreat, on the contrary, Mu Chen and Song Qi stopped here, as if they wanted to see what kind of waves this boulder lake was going to make.

I don't know if Qingyu or the strong people who came to the Ocean Blue Cave before have encountered this situation, anyway, for the changes in the water of such a lake that Mu Chen and Song Qi have seen now, Mu Chen and Song Qi have not read it in any books.

Or the predecessors of the human race have not encountered such a situation, which seems to indicate that Mu Chen and Song Qi are lucky, and it seems that among the predecessors of the human race, someone has encountered such a situation, this is that he or she is also like Mu Chen and Song Qi, stunned, and does not know how to tell at all.

Because, for everything they saw in front of them, Mu Chen and Song Qi felt that this could not be expressed in any language.

You can only understand it, not say it.

It is estimated that this is the situation of Mu Chen and Song Qi.

That's it, Mu Chen and Song Qi waited patiently for a long time, and when the last water curtain condensed, Mu Chen and Song Qi discovered that these condensed water curtains finally built an ice and snow castle for the two of them!

This ice castle has already shrouded the entire lake, and the lake surface has all condensed into ice at some point, and the stone stairs have quietly disappeared, and Mu Chen and Song Qi have found themselves standing on the ice.
