Of course. The biggest feature of the sedimentation purification method used in Xiongan No. 1 Shelter is that the reservoir is large enough and has enough sedimentation volume at one time. In order to ensure smooth cleaning of the sediment at the bottom of the sedimentation tank, the bottom of the tank is pre-installed.

Well, the gravity-driven distributor is a bit like the principle of a waterwheel. It does not require power from a transmission shaft. As long as the amount of sediment reaches a certain level, it will automatically rotate and push the sediment with the help of the overall potential energy of the water body.

into a special cleaning pool.

Therefore, waves will also be generated in the sedimentation tank, and they are big waves that may not seem surprising but are powerful!

Li Dan didn't know the specific structure of the sedimentation tank and thought it was a wave formed by the sewage vortex, so he and Natsume resisted the flood control blocker together. Natsume's face changed when he saw this and said, "Hey! What are you doing! Go away! You can't resist it."

of!"

Li Dan lost her temper. She rolled her eyes at Natsume and said, "I want you to take care of it! If you don't leave! I won't leave either!"

"Hey! You!" Natsume was about to say something, when the undercurrent waves hit the flood control blocker in the channel.

At that time, Natsume felt that her arms were numb and her feet were slipping.

The next second, the overwhelming stench of sewage swept his and Li Dan's bodies into it.

The blocker was torn apart instantly, and a "rumbling" roar of sewage came from the channel. The eyelids of the staff on the second line of defense twitched, but under the supervision of the command staff, no one retreated. After all, the last line of defense was behind them.

If the sewage cannot be blocked here, there will be no time to remedy it.

Water is definitely the most amazing thing in the world. When it is calm, it is so gentle, but when it surges, it is so violent and ruthless.

Water accumulated at one point under high pressure can cut even the hardest steel. At this moment, tens of thousands of cubic meters of sewage rushing into the channel was like a galloping horse trampling over Natsume.

By the time the sewage waves hit the winding passage several times and the lighting equipment kept flashing, the sewage reaching the second flood control line had lost its strength.

Everyone took a long breath and smiled, but the commander's face was extremely ugly. When he saw the wave of sewage receding, he immediately ordered "Save people!!!"

At this time, everyone remembered that there was a team of fifteen people in front of them. They were carrying a few flood control arresters. They should have withdrawn before the waves hit the second flood control line, but now the water has receded.

, but they disappeared.

At that time, more than 20 people poured into the passage and began to look for Natsume and others in the sewage.

But most of the 120-meter-long Z-shaped channel is now submerged, and the deepest part can reach an adult's neck.

It is extremely difficult to find survivors in this environment.

Just when all the rescuers were in despair, a figure swam out of the sewage.

He raised his head suddenly, holding a girl in his arms.
