Chapter 746：

"I don't know, I haven't been in touch recently." This was Hefeng's last answer.

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

"What's wrong?" Hefeng's voice was hoarse, and his spirit was lethargic.

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

"This information is enough." Li Yue turned around and picked up the 'confession' in the recorder's hand.

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

"Then does he want to continue the trial?" Adazhu looked at He Feng, who was still in a trance. Yan Bing nodded seriously and said, "Jin, just don't die."

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

"Contact Gaodi as soon as possible." Yan Bing urged, turned and left.

"I will." Adazhu raised her hand and gave a military salute.

She turned to look at He Feng, her pure white eyes were calm and calm, as if she was calming down.

He Feng's body shook a few times before he was completely awake, but he found that his mind was not very bright.

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

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

On the other side, Liyue and Yanbing took a carriage and headed for the highland.

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

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

Yan Bing opened his mouth and sighed, "Sir Muliang will make the decision."

"Shit's 'Human Spiritualization' experiment!!" She gritted her silver teeth and cursed in a low voice.

"Future City will also send people to participate in the Holy Land Council. You can ask them if Yao'er's mother is still alive." Li Yue's eyes flashed coldly.

Yan Bing nodded and said, "I will go and ask Lord Muliang, I hope he can call the shots."

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

"Time is running out. Before the Holy Land Council begins, we must catch the rat that sneaked into the inner city!" 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 to her temple.

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

"It's all right." Yan Bing said, moving his lower arm, but no longer felt the pain.

"If this level of injury was left in the past, it would take half a year to heal." Yan Bing said with emotion.

She recalled her life in Sacred Sun City. Fractures were a common occurrence when participating in training. She could only rely on cheap healing medicines to barely keep her injuries from getting worse.

"Look forward, the past has passed." Li Yue reached out and took Yan Bing's hand.

"Flying Corpse is dead." Yan Bing relaxed.

The two were silent again until the carriage reached the heights.

Liyue got out of the car first and walked quickly to the transport elevator.

stomping on...

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

"Captain Liyue, Captain Yanbing, and Lord Muliang are not in the palace." Wei Youlan said obediently.

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

"Master Muliang has gone to the outer city, it seems that he is going to build a sewage treatment plant." Wei Youlan said in a clear voice.

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

Xuanwu City, the outer city.

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

He's picking out a location for a sewage treatment plant.

Whoa whoa???

Sewage poured out from the glazed pipes extending from the inner city, and flowed randomly on the land of the outer city.

"Just here." Mu Liang whispered softly.

He descended from the sky and landed on the ground thousands of meters outside the Liuli Pipeline.

□□

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

The subsidence area is rectangular, with a length of two kilometers, a width of five hundred meters, and a depth of twenty to meters.

Mu Liang's thoughts moved, and the glaze spread out from under his feet, covering the surface of the rectangular deep pit to avoid water seepage.

Liuli also divides the rectangular deep pit into equal parts.

!A!

Part of it, looking down from the top, turned into four square deep pits.

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

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

Mu Liang used the same method to dig out the No. 2 sewage treatment line, which is also the standby treatment line of the sewage treatment plant. It is also four square deep pits. When the treatment tank needs to be replaced and cleaned, the No. 2 sewage treatment line can continue the sewage treatment work.

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

She asked gracefully, "Are you enough sand and charcoal?"

After the carriage, swarms of worker ants brought in charcoal and gravel, which soon formed a hill.

"Enough." Mu Liang's lips curled up.

He raised his hand, and the mountain of coarse gravel flew up and fell into the first treatment pool, which was quickly filled.

Then the finer gravel fills the second treatment tank.

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

Yue Qinlan is curious, can the sewage be cleaned with these sand and gravel?

He watched Mu Liang use his abilities 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. 2 sewage treatment line were also filled with sand, gravel and charcoal.

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

"Is this all right?" Yue Qinlan said in surprise.

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

He turned around and the pipe that controlled the sewage was extended.

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

Whoa whoa???

The sewage flows into the first square pool, and after the adsorption of coarse sand and gravel, the large particles of debris in the sewage are intercepted. Before long, 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 tank for the second filtration.

The finer sand can filter finer impurities and the water will flow through it more slowly.

Half an hour later, the second treatment tank was filled with sewage, and the overflowing water was already yellowish I color.

What is Bili Kacha???

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

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

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

"It's already very clear, can you 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, the water quality becomes clear, and there may be substances harmful to the human body in the water. Treating sewage is to prevent the water from polluting all water sources.

"Okay..." Yue Qinlan nodded thoughtfully.

"Where's Zheng An?" Mu Liang asked sideways.

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

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

"Yeah." Mu Liang nodded.

With a move of his mind, the glazed wall rose to the ground, covering the two sewage treatment lines.

"Lord Muliang!!" Not far away, Feiyu flew with the mermaid patriarch Zheng An.

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

"Lord Mu Liang." Zheng An went down to the ground with a cane, and bowed respectfully to Mu Liang.

"Well, it came just right." 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 mermaid will work in the future."

"Yes." Zheng An nodded respectfully.

...for flowers...

"This is the No. 1 sewage treatment line, and here is the standby No. 2 sewage treatment line." Mu Liang briefly introduced the operation principle of the sewage treatment plant.

Zheng An listened carefully and asked questions aloud from time to time.

Mu Liang stopped and said with a serious face: "The sand, charcoal, and activated carbon in the disposal pool should be replaced every ten days."

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

"When cleaning the treatment tank, use the No. 2 sewage treatment line and use it alternately." Mu Liangping said calmly.

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

"Understood." Zheng An nodded again and again.

Mu Liang put his hands behind his back and asked calmly, "What's the problem?"

"Not yet." Zheng An replied respectfully.

"Then it's up to you. I hope the water quality flowing out of the sewage treatment plant is qualified, otherwise you are the only one to ask." Mu Liang's tone was indifferent, but it made people nervous.

"Yes, you won't let the adults down." 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, go back." Mu Liang looked at the elegant woman.

The corners of Yueqinlan's lips rose, and she said gracefully, "In a carriage?"

"Fly back." Mu Liang naturally stretched out his hand, grabbed the elegant woman's slender waist, and took off to the inner city heights.

Zheng An watched Mu Liang leave, and then slowly relaxed, turned to look at the sewage treatment tank, and his eyes were bright.

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

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

"Yeah." Mu Liang nodded casually.

Wei Youlan said obediently: "Lord Muliang, Captain Liyue and Captain Yanbing have been waiting for a long time, and it seems that there is something to report."

"Let them come to the study." Mu Liang's black eyes flashed as he walked to the study thoughtfully.
