Li Yifan thought of the traces of water found on the wall of the stairway before, and understood that water is produced here.

However, he was very strange, "if the water in the whole space comes from here, and it was only a few kilometers from the fog to the ruins before, no matter how far away it is, it should not be volatilized there?"

"No, you are wrong!"

Jijie shook his head and gave a mysterious smile.

"Oh?"

Jijie squatted on the ground, then made a gesture on the ground, "you should have learned the most basic knowledge of geography, heat island effect?"

"The city center generates high heat due to the accumulation of buildings, and then dissipates along the high altitude, finally floats to the suburbs, and finally cools down, and the cooling air is transported to the city cluster." Li Yifan blinked his eyes and frowned: "do you want to say that the water in the tower evaporates through some heat, and then the water vapor radiates from the top of the tower and floats to the outer part of the space, forming a fog?"

"Yes Jijie nodded.

"But there's a basic question. Can this tower make water evaporate? The temperature inside is so low that it's only ten degrees at most. How can it evaporate when it's twenty degrees outside? " Li Yifan said he was puzzled.

"It's very simple, because it's a circulation system of array!" Ji Jie continued to explain with a smile, "on the surface, the temperature of this building is low, so it is impossible for the water to evaporate. But what if it has array effect? "

Li Yifan thought about it. He knew the array fairly well and soon understood it.

"You mean in the array, the position of the building is in the eye of the array?"

"To be exact, it's the position of the South fire and the left fire, and it's also the position of the array eye! According to Qimen dunjia and the five elements, the water in the fire position must be blocked, and it will naturally evaporate a lot! " "The evaporated water comes out from the top of the tower and then floats up into the air," he explained in a deep voice. Under normal circumstances, the water vapor will become cold slowly over such a long distance, and finally condense into fog or even rain. So the people who arranged the array were very smart. They set up another volcanic zone on the periphery. They used the high temperature to heat the water vapor again, so that the water vapor floated to the outermost place, and then condensed into fog. "

"If you're right, there must be groundwater circulation in the fog filled underground. The water condensed by water vapor infiltrates into the underground and then returns to the ruins, forming a complete circulation system."

After hearing this, everyone suddenly realized.

"So it is. No wonder there is so much fog in this place where there is no river in sight and the vegetation is dead."

Jijie smiles. "It's not as simple as you think."

Li Yifan eyebrows surprised, "and?"

"Isn't there something you're curious about? The water vapor of the mist comes from the tower, but when you first entered the ruins, did you hear the sound of water clattering? "

"Sounds like water."

"Yes, I heard it, too!"

"I thought there was a river in the ruins, but I didn't see it at all."

They could not help nodding. At first, before entering the ruins, they did hear the sound of water.

Jijie grinned with a meaningful smile, "have you ever considered why there is underwater sound?"

"This..." They scratched the back of their heads and shook their heads.

Li Yifan frowned hesitantly and pondered: "some of you have said before that you can find this relic because you found something in the relic under the Cliff River near the relic. Right? "

"Well, there is such a thing!" Zujin nodded.

Qiu Qianchi nodded, "what's the problem?"

"Guess, is it possible that the sound of water we hear is actually the sound of the river flowing into the valley?" Li Yifan's words are amazing.

"No way? So far. "

"Yes! The river in the cliff Valley is less than ten kilometers away from here! "

"No matter what, it's impossible to hear the sound more than ten kilometers away?"

Everyone shook their heads and said they didn't believe it. It's ridiculous!

How can they hear the sound of the river more than ten kilometers away? If they really hear it, they can't go to heaven?

However, Ji Jie laughed and said, "in fact, what Li Shao said is right! The sound of water you hear is the sound of water in the valley river. "

"Ha?" The crowd opened their mouths wide.

"Let me explain to you," Ji Jie said with a cool smile. "Have you ever thought about why this space is obviously closed, but the things in the ruins appear in the river tens of kilometers away?"

The crowd was stunned.

"I have just explained that the water in the whole space is circulating, and the water in the space comes from here. But there is a basic common sense, that is, there will be loss in the natural water cycle. Only when the vegetation is very strong, the water will not be lost. But if the water in this space is assumed to be fixed, as long as it circulates, it will dry up one day. It can be inferred that there must be water supply here! ""It's the river tens of kilometers away that supplies water here, and when supplying, the water in the ruins will flow back, and then the things in the ruins will be taken out, resulting in something that should not have appeared in the river!"

People were stunned, such a thing is obviously beyond their understanding.

"Jijie, you said so much, what does this discovery mean?" I don't think this discovery is very useful, do you?

Jijie gave him a white look, "since I put it forward, how can it be useless?"

"All right."

"Now we have found out the circulation system and array in the whole relic, and why there are things in the relic dozens of kilometers away. All of these help me to determine one thing, that is, if we escape from the ruins, we will definitely appear in the river dozens of kilometers away! "

"What?" The crowd was taken aback.

Li Yifan thought, "it's not surprising that the water here is connected with the river outside, which proves that there must be a water system communicating with each other underground."

"Yes! Then the exit must be the water system! " Jijie nodded heavily.

He pointed to the mechanism in front of him, "that is to say, this is the exit?"

"No!" Ji Jie shook his head and slowly explained: "did Zuo Tianshi forget the words that Yin Xue saw at first? It's very clear that only when we reach the top of the tower can we get the treasure inheritance, that is, only when we reach the top of the tower can we leave. In other words, the mechanism here should be connected to the top of the tower, and there must be water on the top of the tower. As long as we pass this mechanism, we can reach the top of the tower directly! "

Hearing this, people couldn't help looking happy.

"Really? After that, you can go straight to the top of the tower? "

Ji Jie looked at them and said with a smile: "otherwise, why is the map only one layer? Master Zuo, look at the map. Is there any trace of damage at the tail
