But from a normal scientific point of view, this is unreasonable.

The volume of the water is not small. Such a lot of water... can't just disappear for no reason! So this must be a weird phenomenon. The equations and the others were not in such a hurry, and Yuan Yue and Xiao

Qi came to this trip with the idea of ​​vacation.

So, they all decided to stay and watch the excitement and see what was going on! When they got up early in the morning, Yuan Yue and Xiao Qi clamored to go to the big lake in the back mountain, so the group came to the back mountain.

.

Although the name of the mountain behind the mountain seems a bit random, it is really not a small mountain, it can even be said to be a very big mountain, and... its style is also very peculiar.

When you look at this back mountain from a distance, you can't tell how high it is at all, but you can be sure that it is very high, because its top reaches straight into the sky, and you can't even tell where its top is! But at such a high altitude

Mountains should usually appear in the form of mountains or mountain ranges, but now this back mountain is just a solitary peak.

It occupies a very small area and looks no bigger than a football field.

This situation is really rare, at least not in the era of Equation.

This single mountain peak with such a high altitude is like a huge ice cone lying upside down on the ground, with its tip reaching straight into the sky.

"This mountain... is really strange. There is no mountain range, just a single mountain?"

Li Zhaowen looked at the mountain from a distance and said curiously.

"Yes, why do people feel worried when looking at such a mountain?

It always feels like it's not very strong. What should I do if the sharper top part suddenly falls down?"

Xiao Qi put his hands on his eyebrows and looked up at the mountain behind him.

This mountain is like a sharp sword rushing straight into the sky, and the ones on the Internet can no longer be seen! "This mountain is already very strange, but there is even stranger water below!"

Yuan Yue also said curiously.

"Look, look, the water is falling again, look..." Not far away, other people shouted in surprise, and when Yuan Yue and Xiao Qi heard that the lake water was falling,

, and immediately rushed excitedly towards the big lake on the other side of the back mountain.

"Quick, go and have a look!"

Arriving at the big lake, Fang Fang and others discovered that the lake actually did not match its name.

It is called a big lake, but this lake is actually not big. It is more like a man-made lake in a park. It is about the size of a football field and about the same size as the base of the back mountain standing next to it.

It can be seen clearly at a glance.

At this time, this large lake was less than half full, and it looked... like a lake that was about to dry up during the spring drought.

"The water in this lake... is so dark in color. Logically speaking, the visibility of such a shallow lake should be able to see very far, but no matter how you look at it, the water is pitch black, with no transparency at all?"

Yuan Yue squatted by the lake, squinted her eyes and looked hard into the lake, but she couldn't see anything. The lake was pitch black and thick in color. Although the water was shallow, she couldn't see anything.

"This lake is not dark, but deep... This lake can be said to be very deep, so deep that... we can hardly imagine it."

Fang Fang took a step forward, looked at the dark lake in front of him, and said with a serious expression.

I don't know why, but as soon as he came near the back mountain and the big lake, he felt an indescribable strange feeling in his heart.

I can't tell if it's good or bad, anyway...it just feels weird here.

"Hey, if you put it this way, do you think this mountain and this lake are the same thing?

It’s the kind of feeling that if you pull up this mountain and insert it into this lake, it will just fit in!”

Li Zhaowen pointed to the back mountains and the big lake in front of him and said.

"Eh?

Really! It’s like this mountain is the cover of this lake!”

Xiaoqi also nodded.

"set?

cover?"

When Fang Fang heard what Li Zhaowen and Xiao Qi said, he was stunned for a moment. Then he seemed to understand something and looked firmly at the bottom of the lake.

He used his spiritual energy.

Equation's eyesight is much better than that of ordinary people. He is even better than ordinary gods. But just now he saw nothing in the lake. When he looked into the water, there was only darkness.

He was also puzzled, so this time he used his spiritual power.

Fang Fang didn't believe that he couldn't see the bottom of the lake! Sure enough, this time his vision was much clearer and he could clearly see the situation in the water.

The water of this large lake and the appearance of the bottom of the lake are no different from normal ones. The walls of the lake are all covered with mud that has accumulated for many years, and there are some unknown aquatic plants growing on it.

The water in the lake is slightly turbid, and it is constantly flowing, and as it reaches the bottom of the lake, the undercurrent becomes more and more turbulent. As expected, the surface of the lake is calm, but there is a surging undercurrent below the lake! "A turbulent undercurrent?"

Fang Fang was stunned for a moment and couldn't help but mutter to himself.

"What's wrong?"

Yuan Yue on the side heard Equation's question and couldn't help but stepped forward to ask.

"This is a famous dead lake with no flowing water, so why... is there still an undercurrent surging at the bottom of the lake?

This is unscientific!”

Fang Fang shook his head strangely, looking like he couldn't believe it.

"Maybe... it's caused by the wrong direction of the water flow?"

Yuan Yue thought for a while and found an explanation.

"But if the water flow wants to produce convection, it also needs the assistance of external force, and it cannot easily produce a resisting water flow! At least it requires water flow, wind, air pressure, etc..." At this point, the equation suddenly

He stopped for a while and looked at the lake in front of him with a look of enlightenment, as if he understood something.

He hurriedly set his eyes on the lake again, and then looked hard at the bottom of the lake.

In fact, many dead lakes are named backwater lakes because they have no channels connected to any rivers and oceans. However, in fact, the determination of many lakes is inaccurate, because in fact, if such a lake is very deep, then you have no way to determine it.

Are there other channels at the bottom of the lake that connect it to the rivers and oceans outside?

And if there are channels connecting other rivers at the bottom of the lake, then we can understand the reason for the sudden rise and fall of the water level. At least where the water went when the water level dropped can be explained! But after looking at it for a while, the equation was retracted

He looked at me with a very strange expression on his face! "How is it?"

Is there a passage under the water?”

Li Zhaowen looked at him curiously and asked.

"I can't see clearly..." Fang Fang shook his head and replied softly.

"What?

You can’t see clearly?”
