Chapter 764 Modern Water Plant

"Of course, if a Bai Ren is determined to die, it is difficult to stop him." The short man whistled and walked to the side of Mr. Zhou. "There are witnesses and evidences. You should have nothing to deny, right?"

"I...you..." Zhou Sheng watched the strong man disintegrate bit by bit in the flames, and he couldn't say a word for a long time.

Was this plan noticed by the Bureau from the beginning?

Even the alchemists at the garrison level pretended to be street thugs to participate, but he didn't notice it at all...

"Since, since when?" He muttered this sentence for a long time.

"Of course, it was when you bought a large amount of arsenic." The other party shrugged, "Although you hired a lot of people to buy it separately, this thing is one of the goods supervised by the Bureau. The sales volume has increased suddenly in a few days. We must pay attention to it. But Mr. Zhou, I didn't expect that you could contact the alchemists of the Seven Star Privy Council. This is actually an unexpected gain."

She was laughing at herself.

Zhou Sheng could see this from the short man's eyes.

The plan that I thought was secret was not worth mentioning in the eyes of these people...

"Why don't you stop me directly?" Young Master Zhou gritted his teeth and said, "Do you just want to see me laugh!?"

"Because Lord Xia also wants to evaluate the ability of this water supply plant to deal with crises." The woman who appeared later said indifferently, "Otherwise I would have wanted to crush your bones to pieces!"

Zhou Sheng shuddered suddenly.

"Everyone can live a good life in Jinxia City, why do you still do such a thing? I checked the files. You have been in Shenzhou since you were born, and you are not a qi sensor. There is no reason to collude with the Privy Council." Her eyes were like looking at a dead person, "You have passed the imperial examination, what is kindness and righteousness in your eyes?"

Can everyone live a good life?

Ha... How ridiculous...

The real good days are gone forever.

Zhou Sheng closed his eyes and slowly collapsed.

In the factory building on the other side of the water supply plant, it was another scene.

The sealed building was brightly lit, and nearly a hundred employees went back and forth between the various water purification pools, extracting water samples, conducting tests and reporting the results. In the office at the highest point of the factory, Xia Fan, Mo Yun and the high priest Senya were paying attention to whether the design indicators of the entire system met the qualified standards.

"The pH value of the first plant pool was abnormal," Senya said after receiving the record submitted by an elf, "not only arsenic was poured into the water, but also some kind of plague bacteria."

"It seems that what Qixing prepared is this thing." Xia Fan said slowly, "But they don't know that the so-called water supply plant is not just to bring river water into the city and then send it to every household."

The greatest significance of centralized water supply is to ensure water safety.

If even the safety of the water source cannot be guaranteed, then the disadvantages of this project can be said to be far greater than the advantages. Therefore, a qualified tap water system must have a reliable and sensitive purification device, rather than just pumping water into the pool.

Otherwise, even if the enemy does not enter the water plant, it can still seriously threaten the water supply of Jinxia City by only poisoning the upper reaches of Jiujiang.

This set of purification pools is the embodiment of its technical content.

After learning from the Privy Council that someone might be plotting to sabotage the water plant, Xia Fan responded very early - he deliberately kept his troops in place, allowing the other party to complete all preparations, and then suspended the tap water supply on the night of the action, treating this sabotage as a practical assessment exercise.

Those open-air pools are actually just reservoirs and multi-stage sedimentation tanks, and their main purpose is to filter the sand and mud carried in the river to make the water as clear as possible.

As a slightly soluble mineral, arsenic is not a good choice for poisoning. Even if the criminal prepared two carriages of goods, it would be a drop in the bucket for the huge throughput of the sedimentation tank. Only a very small amount of arsenic can be mixed into the water and flow into the fully enclosed purification plant. Relying on layer by layer dilution, this dose of highly toxic substances is not very dangerous.

Moreover, the first pool they flow through is an adsorption pool composed of root nodule grass.

These crops, which are planted in large quantities on the beach in the east and make rice ears grow on the sand, can still play their unique purification role when moved to the water plant. Whether it is salt crystals or other mineral impurities, the root nodule grass has a strong ability to capture and consolidate, especially when there are elves supplying air for it, the changes in the root nodules it produces can be seen directly with the naked eye.

Because of this, Xia Fan is not too worried about Zhou Sheng's criminal methods.

What he really cares about is the foreign air sensor who has mixed into the team.

According to Luo Qingqing's observation, this person's level should be around Bairen. If he is placed in other small places, he is already a master. It is impossible for him to become a street gangster. In addition, the Affairs Bureau has reported the news of the infiltration of the Seven Stars many times before, and the "evil attack incident" planned by the other party in the border town of Shenzhou. Therefore, the head of the Privy Department, Qian, keenly identified him as a Seven Star spy, and he must have other intentions to cooperate with Zhou Sheng.

Facts have proved that the latter's poison is much more troublesome.

Compared with slightly soluble minerals such as arsenic, the blight bacteria are difficult to be removed by precipitation, filtration and other means, and will not be solidified by plants. It is a real killer.

"Live water is entering the secondary purification tank."

"The amount of disinfectant added is twice the normal amount."

The employees were unaware of the situation outside the factory. They thought it was just a test that Xia Fan had done on a whim, and they continued to follow the rules in every step.

"Will there be any problems?" Mo Yun said with a little worry. Mechanical engineering is what she is good at, but germs are something in another field.

"Don't worry, this is also a problem that the water supply plant has anticipated when it was designed." Xia Fan tilted his head and glanced at the control system beside him - it can be said that without the resources obtained from the escape tower, such a large water supply plant would be out of the question. For example, the disinfectant injected into the secondary purification pool comes from the by-product of the salt factory on the seashore. With sufficient electricity, as long as the sea salt crystallized by electrolysis, a stable and reliable chlorine can be obtained continuously. Chlorine will generate hypochlorous acid when it enters the water body, which has a strong killing effect on various germs.

In order to ensure safety, only a small amount of chlorine will be injected into the purification pool on weekdays, and when the plant pool in front detects an abnormal number of harmful bacteria, the disinfectant will be doubled.

Soon, the living water that had undergone multiple levels of disinfection was introduced into the pumping pool - this was also the last checkpoint of the water supply plant. Once it entered the main pipeline, it would spread in a very short time and flow into thousands of households in Jinxia City.

But tonight, all the gates of the pumping pool were closed, completely cutting off the water supply.
