[PS: Thank you to the boss Ge Yi Mama for his more than 100,000 reward!]

The fat man quickly raised his pants and rushed over, and asked him what was going on.

The hunting dogs next to them all started to move, but the hunting dogs were well-trained and did not bark at all.

"It's okay, it sounds like the sound of tides," Chen Hao said.

The sound was still clattering. When Wu Xie heard it, he said, "Why do I feel like a beast licking water?"

"No, if this is a wild beast, it must be quite big. Could it be a tiger?" said the fat man.

The young man did not speak, but walked quickly towards the voice closest to him, but when he got closer, he saw nothing.

But at this time, the sound came out again. In the center of the lake, everyone hurriedly looked at the center of the lake, which was pitch black and could not see anything.

Chen Hao used the Yin-Yang Eye to find that a huge vortex appeared in the center of the lake, just like the sea eye of the South China Sea.

Countless water flowed into the vortex. It was supposed to be a siphon effect, and the lake water here was pumped into the underground river.

"It's the siphon effect, and a big vortex appeared in the center of the lake!" Chen Hao said.

But everyone could not see the changes in the center of the lake, and the flashlight could not be so far away. They couldn't help but be as anxious as an ants on a hot pan, spinning around.

The young man walked forward a few steps. The lake shore under his feet was still wet and the water level was falling rapidly. Seeing this, everyone immediately realized that what Chen Hao was right.

"This is indeed a siphon effect! You see that the water level has dropped so much, which means that there is a larger lake near this lake, with many underground river connections underneath." Wu Xie said.

"What are you siphon? Siphon Erguotou?" The fat man asked in confusion.

"The siphon effect is caused by the gravitational force of the moon. To put it simply, there is a toilet at the bottom of the lake. The water is pumped away as soon as the pressure is raised. When the pressure is calmed, the water will slowly come back. Do you understand?" Wu Xie explained.

Chen Hao frowned and said, "There is a siphon effect in such a small lake. The bodies of archaeological team members who were thrown into the lake by Panma and others back then were probably sucked to the bottom of the lake by the siphon effect, and even into the underground rivers. If we want to salvage it, we have to dive to the bottom of the lake."

"We are in trouble now. We don't bring any diving equipment at all. We don't know how deep the bottom of the lake is. If it is dozens of meters deep, we will definitely not be able to dive to the bottom of the lake just by just one breath. We have to transport some diving equipment in." Wu Xie frowned.

"I looked at the water quality in this lake and guessed it was 60 meters deep at most, and the shallow area was thirty or forty meters." Chen Hao said.

After hearing his words, Wu Xie had an idea and said to everyone: "By the way, how long can you hold your breath in the water? I see those professional freedivers can dive to more than 100 meters in one breath. Although we do not have those professional skills, if the bottom of the lake is only thirty or forty meters, maybe we can try it."

"Ha, Fatty, I have a lot of lung capacity. I can hold my breath in the water for 5 minutes!" The fat man said proudly.

"Come on, fat man, this is deep diving, not in the swimming pool. You are so large that you receive more water pressure at the bottom of the water and consume more oxygen. How can you hold your breath for 5 minutes? It would be amazing if you can last more than three minutes for ordinary people. Except for Ahao, I'm afraid no one can exceed three minutes." Wu Xie said.

The fat man said, "Even if this happens, I should be fine if I last for two minutes. I think the biggest problem is that we don't have flippers and the diving speed is too slow. I'm afraid I'll lose my anger before I touch the bottom of the lake."

"This is easy to deal with. You can dive with the weight of the stone. Anyway, we also brought ropes and tied the stones to the ropes so that they can sink with the stones." Chen Hao reminded.

"Yes, this is a good way!" the fat man said in agreement.

"But... we can only stay in the water for a minute or two, and we must not show off our power. If we lose energy, we must retreat in time. How much we can gain tomorrow's actions actually depends on Ah Hao, how much he can catch from the water." Wu Xie said.

When everyone heard his words, they all nodded in agreement. After all, they had already seen Chen Hao's abilities under the water, so there was no doubt about this.

When they went to the Xisha Underwater Tomb last time, they had already seen Chen Hao's pervert. He could easily move under the water for an hour or two, and the speed was very fast.

With this time, I can walk the entire lake floor and probably have extra time. Everyone naturally put their hope on Chen Hao, hoping that he could salvage something from the lake.

Then, everyone discussed tomorrow's matters, made bamboo rafts, found the right stone, and then explored the depth of the lake water. After breakfast, they started salvage.

Except for Xiaoyu, everyone here has good water properties. Even the two people in the mountains, Agui and Yuncai, have good water properties, so they can help with bamboo rafts.

Xiaoyu can't swim, so she must not be allowed to go into the water. It's okay to let her cook or something.

Yuncai couldn't get into the water either. If she had to wear a bra and Xiao Nene and go into the water with them, the fat man would probably have no intention of working.

After discussing the action plan, it was already past 11 o'clock in the middle of the night, everyone returned to their tents to rest.

No words all night.

On the second day, everyone got up early.

Yuncai and Xiaoyu picked some wild fruits for everyone, added the prepared bacon and rabbit meat, and cooked their local specialty (wild fruit bacon porridge).

The porridge tastes very sweet, mixed with the cured taste of rabbit meat and the fragrance of wild fruits. It tastes really delicious. The fat man drank 7-8 bowls alone.

After breakfast, everyone cut down some bamboos in the nearby bamboo forest according to the plan agreed yesterday and made two bamboo steaks.

Then, I found several stones weighing dozens of kilograms as objects to dive.

He moved the things to the lake, and the men took off only a pair of big shorts and hugged the stone and prepared to dive.

"Brother, be careful!" Xiaoyu reminded with a worried face.

After the conversation that night, she already knew what Chen Hao's identity was, so she would not dissuade him from what he did, so as not to make Chen Hao angry.

"Sister-in-law, don't worry. This kid can move under the water for an hour or two, and even a professional diver is not as good as him." said the fat man.

"Xiaoyu, don't worry, I will be careful!" Chen Hao said.

Then, everyone carried the bamboo line to the center of the lake.
Chapter completed!
