The lake is very deep.

But the lake water is as clear as a mirror.

Under the guidance of the Crocodile King, Qin Feiyang and Miss Longfenglou continued to sink.

The cool lake water makes people feel happy.

After a while.

The two of them and the beast sank to the bottom of the lake.

There is thick mud at the bottom of the lake. Looking around, no living things can be found.

If you were here alone, you would feel scared.

Because it's too quiet.

It's so quiet that one can't help but feel scared.

Qin Feiyang glanced around and said through a message: "Start looking!"

Miss Longfenglou nodded.

But Crocodile King was careless along the way.

Time passed by in a breath.

The Crocodile King became impatient.

It looked at Qin Feiyang and Miss Longfenglou and said: "Two eldest brothers and eldest sisters, I have really searched down here and even dug three feet into the ground. I dare to guarantee with my life that there is nothing suspicious here."

Qin Feiyang smiled and said: "If you are not happy, you can go up and wait for us."

"Okay, okay, I'll look for it with you."

The Crocodile King was helpless.

Miss Longfenglou suddenly said: "Little crocodile, I want to ask you a few questions."

"what is the problem?"

The Crocodile King was suspicious.

Miss Longfenglou said: "Where does the water in this lake come from?"

"nonsense."

"Of course it accumulates when it rains."

Crocodile King Road.

Miss Longfenglou said: "Then let me ask you again, has the water in this lake ever dried up?"

The Crocodile King thought for a while, shook his head and said, "That's not true."

"No?"

Miss Longfenglou frowned.

It seemed quite unexpected.

"What's the matter?"

The Crocodile King looked at her in confusion.

"I heard from the Ant King that it rarely rains here, right?"

Miss Longfenglou did not answer the question.

"right."

"It's common for it to rain once every few years or even decades."

The Crocodile King nodded.

"That's right."

Miss Longfenglou said, her eyes sparkling.

"What's wrong?"

"My dear eldest sister, can you make it clear once and for all that you are making me feel very uncomfortable!"

The Crocodile King was a little angry.

Miss Longfenglou glanced at it and said with a smile: "It has only rained for so long. Even if the temperature here is very good, there will be signs of evaporation."

"What's the meaning?"

Crocodile King still doesn't understand.

Qin Feiyang started to think about it.

Traces of evaporation...

Sudden.

As if he had thought of something, he looked at Miss Longfenglou and Crocodile King, and said, "You guys wait for me here, I'll go to the shore to have a look."

"No need to look, I've already observed it."

"On the shore of the lake, there are no other traces of water except the traces of water on the current horizontal surface."

Miss Longfenglou said.

"You mean..."

Qin Feiyang was surprised.

"That's right."

Miss Longfenglou nodded.

"etc."

"Can you guys say something I can understand?"

"If you do this again, I'll be angry!"

Crocodile King said angrily.

Why do you say something as if you are playing a riddle?

Miss Longfenglou glanced at the Crocodile King, looked at Qin Feiyang and said: "Explain it to it!"

After that, he turned back and continued searching.

"talk!"

Crocodile King looked at Qin Feiyang.

Qin Feiyang shook his head, smiled, and said via voice: "No matter where the water is, no matter what the weather is like, will it evaporate over time?"

"right."

Crocodile King Road.

"After evaporation, will the water level become less?"

Qin Feiyang asked again.

"That's right."

The Crocodile King nodded.

"Isn't this right?"

"The water in this lake will also evaporate, and the water level will also drop."

"After the water level drops, there will inevitably be water traces left on the soil or rocks on the shore."

"But Ruoxue just said that she didn't find any other traces of water on the shore."

"What does this mean?"

"It means the water here has not evaporated."

"Is this phenomenon reasonable?"

Qin Feiyang said.

"unreasonable."

Crocodile King said without thinking.

But as soon as it finished speaking, it looked stunned.

"I understand, I understand."

"What you mean is that the water here is not ordinary water. Even if there is sunlight, it will not evaporate."

"Is it right?"

The Crocodile King looked at the two of them.
