When I looked under my feet again, I found that the water level had dropped a lot, and the stone beach was all wet. Zhang Zhuxun and his brother didn't show any abnormality when they were at the lake before. In other words, the lake water had dropped a lot while they were taking a nap.

, it dropped so drastically.

The fat man bent his hands into an arch shape, put them on his forehead and looked into the distance, wondering: "What's going on? Is there a leak at the bottom of the lake?"

After Wu Xiaoxie thought for a moment, he understood what was going on and explained: "This should be a geographical phenomenon called the siphon effect."

The fat man still didn't understand, "Siphon what, siphon Erguotou?"

"This lake does seem to be connected to the underground river. There may be a larger lake nearby that is connected to it. Affected by tides or air pressure, the lake here is connected." Wu Xiaoxie explained in detail.

"For example, small lakes and large lakes are both magnets. If the siphon effect is caused by the gravity of the moon, then the moon is also a big magnet. The attraction of the big lake must be greater, so there is a pressure difference between the large and small lakes. The water in the small lake

It will be pumped into the big lake, so the water level of the small lake in front of us has been reduced."

Wu Xiaoxie looked up at the sky as he spoke, and suddenly realized something, "I understand!"

The fat man had just explained the siphon effect and the magnetism of the moon clearly, "Oh, it's just like a flush toilet, so there are eyes at the bottom of the lake, so the water is sucked away. By the way, what do you understand?"

Zhang Zhuxun spoke softly, "No wonder we can't find anything. You see, the water level has dropped by more than ten meters. If there was a siphon tide here every night, those things from back then might have been sucked to the center of the lake.

, we looked for it in the shallows on the shore, it was just a waste of effort."

Wu Xiaoxie nodded and confirmed his statement, "No wonder the area near the shoal is bare. There is nothing but stones. It turns out that everything has been sucked away."

Yun Cai listened silently and couldn't help but ask: "What are the bosses looking for?"

The fat man said "Shh" mysteriously, "Little girl, don't ask around, you will have nightmares."

Yun Cai was still unwilling to give up. She wanted to increase the weight of her cooperation with these people, "Is the thing you are looking for at the bottom of the lake? This lake is very deep. No matter how good the water is, no one can dive to the bottom, and the bottom is very dangerous.

You should find some professional salvage workers, they have professional equipment."

The fat man smiled and raised his eyebrows, "Little girl knows a lot."

Yuncai pursed her lips and smiled, "A few years ago, there were actually people here who came here to salvage things. I saw them wearing clothes as smooth as fish skin and carrying steel bottles on their backs."

What Yun Cai revealed was something Zhang Zhuxun and the others did not expect.

Then he winked at the fat man. The fat man understood what he was thinking. He came close to Yun Cai, said a few nice words, and then asked, "Sister Yun Cai, did you see clearly what they were fishing for?"

Yuncai shook his head, "There were people guarding the surroundings. I just took a look at them from a distance, but some of those people looked a little different from us."

The fat man asked, "What's different?"

"Most of those people have very white skin. Oh, no, there are a few who are as black as coal. They have set up many tents by the lake. The people guarding the edge are all armed with guns. It looks a bit scary.

." Yuncai recalled.

Wu Xiaoxie frowned slightly, why does this description sound a bit like a foreigner?
