Tamer: I build my home on the back of Xuanwu

"I don't know, I haven't contacted you recently." This was Hefeng's last answer.

As soon as he finished speaking, the confusion in his eyes disappeared, and his spirit slowly recovered.

"What's wrong?" He Feng's voice was hoarse and his spirits were listless.

"It's the limit." Adazhu let out a long breath, reached out and rubbed his temples.

"This information is enough." Liyue turned around and picked up the 'Confession' in the recorder's hand.

"I'm going to see Master Mu Liang." She quickly left the interrogation room.

"Then will he continue the interrogation?" Adazhu looked at Hefeng who was still in a trance.Yan Bing nodded and said seriously, "Jian, just don't die."

"Understood, leave it to me." Adazhu nodded thoughtfully.

"Contact Gao Di as soon as possible." Yan Bing warned, turned and left.

"I will." Adazhu raised his hand as a military salute.

She turned to look at He Feng, her pure white eyes were calm and unwavering, as if she was resting in peace.

He Feng's body shook a few times before he became fully conscious, but found that his brain was not very bright.

The next moment, he was controlled by Adazhu again, asking similar questions repeatedly to avoid missing information.

The same question, in the minds of different people, will get different answers.

On the other side, Li Yue and Yan Bing took the carriage and headed for the high ground.

In the carriage, Yan Bing and Li Yue were silent for a long time.

"Don't tell Yao Er yet, tell her after the investigation is clear." Li Yue said in a depressed mood.

Yan Bing opened his mouth, sighed and said, "Lord Mu Liang will make a decision."

"Bullshit experiment of 'human spiritual instrumentation'!!" She gritted her silver teeth and cursed in a low voice.

"Future City will also send people to participate in the Holy Land Council. At that time, you can ask them if Yao'er's mother is still alive." Li Yue's eyes flickered coldly.

Yan Bing nodded and said, "I will ask Master Mu Liang, and hope he can make the decision."

Li Yue's eyes flickered slightly, Mu Liang should agree, right?

"Time is running out, we have to catch the rats that have sneaked into the inner city before the Holy Land Council begins!" Yan Bing took a deep breath and took off his helmet.

"Let's see how Mu Liang arranges it." Li Yue raised her hand and pressed I on her temple.

She tilted her head and asked, "How is your hand?"

"It's healed." Yan Bing moved his arm as he spoke, but he could no longer feel the pain.

"In the past, it would have taken half a year for an injury of this degree to heal." Yan Bing said with emotion.

She thought of her life in Shengyang City, when she participated in training, fractures were common, and she could only rely on cheap healing medicines to barely keep her injuries from getting worse.

"Looking forward, the past has already passed." Li Yue reached out to hold Yan Bing's hand.

"The flying corpse is dead." Yan Bing relaxed.

The two were silent again until the carriage reached the high ground.

Liyue got off the car first, and walked quickly to the transportation ladder.

stomping on...

The two hurried into the palace, walked across the main hall to the study, and met a little maid on the way.

"Captain Liyue, Captain Yan Bing, Lord Mu Liang is not in the palace." Wei Youlan said obediently.

"Where did you go?" Li Yue asked hastily.

"Master Mu Liang has gone to the outer city, it seems that he is going to build a sewage treatment plant." Wei Youlan said crisply.

865: I'm asking you. (1 more)

Xuanwu City, the outer city.

Mu Liang was suspended in the air 50 meters above the ground, looking down at the area under his feet.

He is picking a suitable location for a sewage treatment plant.

clatter clatter???

Sewage gushes out from the glazed pipes extending from the inner city, flowing randomly on the land of the outer city.

"Right here." Mu Liang muttered softly.

He fell from the sky and landed on the ground a thousand meters away from the glazed pipe.

□□

Mu Liang's black eyes lit up, and the soil under his feet slowly sank, which was tamping the foundation.

The sinking area is rectangular, with a length of 2000 meters, a width of 500 meters, and a depth of [-] to [-] meters.

With a thought of Mu Liang, the colored glaze spread out from under his feet, covering the surface of the rectangular pit to prevent water seepage.

At the same time, Liuli divides the rectangular pit into equal parts.

!Ah!

Part of it, looking down from top to bottom, turned into four square pits.

This is the treatment pond of the sewage treatment plant, also called the filter pond, which is the result of Muliang's improvement.

This is another world, not the earth. There is no professional equipment and water detection device, and the sewage can only be treated by physical methods.

Mu Liang used the same method to dig out the No. [-] sewage treatment line, which is also the backup treatment line of the sewage treatment plant. It is also four square deep pits.When it is necessary to replace and clean the treatment tank, the No. [-] sewage treatment line can continue the sewage treatment work.

"Mu Liang!" Not far away, Yue Qinlan got off the carriage.

She asked elegantly, "Are these gravel and charcoal enough?"

Behind the carriage, swarms of worker ants brought charcoal and gravel, which quickly piled up into hills.

"Enough." The corners of Mu Liang's lips curled up.

He raised his hand, and a mountain of coarse sand flew up and fell into the first processing pool, filling it up quickly.

Then the finer sand fills the second grid treatment pool.

There are two types of sand, coarse sand and fine sand, both of which are used to filter impurities in sewage.

Yue Qinlan looked curiously, could the sewage be cleaned up with these gravels?

He watched Mu Liang use his ability to make piles of charcoal fly up and fall into the third square pool.

The fourth square pool is filled with activated carbon.

Using the same method, the four square pools of the No. [-] sewage treatment line were also filled with gravel and charcoal.

"It's done." Mu Liang clapped his hands, very satisfied with his masterpiece.

"That's enough?" Yue Qinlan asked in surprise.

"Well, this is the easiest way to deal with sewage. There is no better way for now, so let's do it for now." Mu Liang said indifferently.

He turned around, and the sewer control pipe extended out

, docked at the water inlet of the sewage treatment tank.

clatter clatter???

The sewage flows into the first square pool, and the large particles in the sewage are intercepted by the adsorption of coarse sand.Not long after, the water flowing through the first square pool became much clearer.

"It's really cleared up a lot." Yueqin Lanhong's lips parted slightly.

After the water is full, it flows into the second grid treatment pool for the second filtration.

Fine gravel filters out finer impurities, and the water flows through them more slowly.

Half an hour later, the second grid treatment pool was filled with sewage, and the overflowing water was already yellowish in color.

Kacha???

The water flowed into the third treatment pool, and there was a crackling sound in my ears, which was the charcoal absorbing water.

It was already an hour and a half after the water filled the third treatment pool.

The charcoal absorbs more impurities in the water, and when it flows to the fourth treatment pool covered with activated carbon, the water has become very clear.

"It's very clear, can I drink it?" Yue Qinlan raised her hand, and the water flowing to the fourth treatment pool floated up.

Mu Liang said gently: "For safety's sake, don't drink it, it can be used to irrigate the farmland.

The treated water only has less impurities and the water quality becomes clear. There may be substances harmful to the human body in the water.Sewage treatment is for the sake of water circulation and at the same time prevents sewage from polluting all water sources.

"Alright..." Yue Qinlan nodded thoughtfully.

"Where's Zheng An?" Mu Liang asked with his head turned.

Yue Qinlan said crisply: "It's already on the way."

The sewage treatment plant will be handed over to the mermaids for management, and some precautions must be instructed in person.

"En." Mu Liang nodded.

With a thought, the glazed wall rose from the ground, covering the two sewage treatment lines.

"Lord Muliang!!" Not far away, the flying fish came carrying Zheng An, the leader of the mermaid clan.

The flying fish circled and then fell, next to the sewage treatment plant.

"Lord Mu Liang." Zheng An lowered his cane to the ground, and bowed respectfully to Mu Liang.

"Well, it's just in time." Mu Liang nodded indifferently.

He stretched out his hand to signal the sewage treatment plant, and said in a clear voice, "This is where the mermaids will work in the future."

"Yes." Zheng An nodded respectfully.

...ask for flowers...

"This is the No. [-] sewage treatment line, and this is the spare No. [-] sewage treatment line." Mu Liang briefly introduced the operation principle of the sewage treatment plant.

Zheng An listened carefully, asking questions from time to time.

Mu Liang stopped in his tracks and said with a serious face, "The gravel, charcoal, and activated carbon in the treatment pool should be replaced every ten days."

"Yes, I remember." Zheng An nodded vigorously.

"When cleaning the treatment pool, use the No. [-] sewage treatment line and use it alternately." Mu Liangping said in a peaceful voice.

Two sewage treatment lines are used alternately to improve the efficiency of sewage treatment.

"Understood." Zheng An nodded repeatedly.

With his hands behind his back, Mu Liang asked calmly, "Any more questions?"

"Not yet." Zheng An respectfully replied.

"Then I'll leave it to you to be in charge here. I hope the quality of the water flowing out of the sewage treatment plant can pass, otherwise you're the only one asking." Mu Liang's tone was calm, but it made people nervous.

"Yes, I will not disappoint you." Zheng An lowered his head.

"Well, let's go." Mu Liang waved his hand.

"Yes." Zheng An bent down and bowed again.

"Let's go, we're going back." Mu Liang looked at the elegant woman.

The corners of Yue Qinlan's lips raised, and she said elegantly, "Take a carriage?"

"Fly back." Mu Liang naturally stretched out his hand, wrapped around the elegant woman's waist, and flew into the air towards the high ground in the inner city.

Zheng An watched Mu Liang leave, then slowly relaxed, turned around and looked at the sewage treatment tank, his eyes sparkling.

On the other side, Mu Liang and Yue Qinlan descended from the sky and landed in front of the palace smoothly.

"Lord Muliang!!" Wei Youlan walked out of the palace to greet her.

"En." Mu Liang nodded casually.

Wei Youlan said obediently: "Lord Mu Liang, Captain Li Yue and Captain Yan Bing have been waiting for a long time, and they seem to have something to report."

"Let them come to the study." Mu Liang's black eyes gleamed, and he walked to the study thoughtfully.
