101 Filtration

Chen Yang carved a message on the wooden board, and suddenly saw Wen Ying's appearance of wanting to speak and stopping, so he said suspiciously, "What's wrong?" ”

Wen Ying: "There's a sentence I don't know if I should say or not. ”

The fat man suddenly said excitedly: "It's all about you, you're still hiding, let go of a fart!" ”

Wen Ying didn't get angry because of the fat man's foul mouth, and said, "What I just said may be the most hopeless choice. ”

Everyone was stunned, not knowing what she meant by this.

Wen Sakura: "Before I brought you to the dam, I had already surveyed a lot of municipal water systems, and the current municipal system is like a blank sheet of paper, as long as you can avoid crawlers, you can see anything you want. ”

Chen Yang asked, "What do you see?" ”

Wen Ying: "The groundwater is also polluted!" ”

The fat man's eyes widened.

Chen Yang frowned, thinking about what Wen Ying said.

"This shouldn't be, I can understand that surface water seepage can cause local pollution of groundwater, but how can it be ······"

Wen Ying interrupted him: "It was deliberately polluted!" ”

"IF YOU WANT TO TALK ABOUT THIS MATTER, YOU HAVE TO MENTION A PERSON, HIS NAME IS DOC. HE, SOME PEOPLE CALL HIM DR. HE, HE IS SAID TO BE A FORENSIC DOCTOR IN THE PAST, ABOUT A MONTH AGO, DOC. HE PUBLICLY DECLARED THAT HE HAD A CLEAN WATER SOURCE, AND USED THIS TO RECRUIT A LARGE NUMBER OF UNINFECTED SURVIVORS AS HIS SUBORDINATES, EXPAND HIS POWER, AND SET UP AN ORGANIZATION CALLED 'SCALPEL'."

Chen Yang: "What does he want to do by doing all this?" ”

Wen Ying: "I don't know, but his power has been extremely strong, about 1/4 of the remaining uninfected people in Jiangbei City have been recruited by Dr. He, and now the only one who can compete with him is the 'BELIEVER' Saint Organization, of course, that is a much larger group, I guess that Dr. He may be using them as pawns to prepare for the final escape from Jiangbei City, after all, as long as the brain is not stupid, you can see the current situation of Jiangbei City." ”

The fat man sneered: "It may also be that I have thought about the addiction of the Earth Emperor, how perverted and perverted this kind of person's psychology is, who knows." ”

What the fat man said is not impossible, but this is no longer the most important issue.

Zheng Jing heard the meaning of Wen Ying's words, so he said, "You mean, we are going to snatch the water from this Dr. He's hands?" ”

Wen Ying nodded: "At present, this seems to be the only way." ”

Zheng Jing: "How many of them are there?" ”

Wen Ying: "About 3,000-4,000 people. ”

There was a deathly silence, and Wen Sakura was silent.

5 people, against 3000 people, can this be called war?

Chen Yang calmly carved Dr. He's name on the wooden board, and then marked a triangle on the back, and the municipal water supply plan above, Chen Yang thought for a long time and erased it with a horizontal line on it.

Fat man: "Chen Yang, don't be in a hurry to deny the first plan, according to me, what this chick said may not be conclusive, I don't believe that every drop of water in the ground is polluted, the most unfortunate thing is that we can divide into two ways, two people to get the municipal water supply, and the other two people to get rid of the DOC. HE ······"

In the end, the fat man basically has no confidence, and the five people can't get rid of Dr. He, and now after such an analysis by the fat man, two people have gone to get rid of Dr. He, and the fat man himself can't convince himself.

So he coughed and muttered, "I'm just giving you a list of possibilities······"

Chen Yang turned his back to everyone and fell into deep thought in front of the plank, he needed to clear his thoughts.

At this time, Dai Yiqing's voice suddenly sounded crisply.

"Uncle Chen Yang, I have an idea that I don't know if it's right."

Chen Yang came back to his senses and looked at Dai Yiqing, he suddenly had a trace of intuition in his heart, he felt that Dai Yiqing could give him the answer to his question, this intuition came very abruptly and unreasonable, but it was very strong.

Chen Yang said: "Qinqing, what do you think can be said!" ”

Chen Yang's tone was completely communicating with Dai Yiqing as an adult, because he knew very well that although Dai Yiqing was not very old, her IQ was enough to communicate and communicate with adults normally, and even think about complex logical problems.

Dai Yijing saw that all the eyes of everyone were on him, he couldn't help blushing a little, puffed up and said: "I probably heard that someone has reconstructed the DNA of the HeLa virus, but I think that no matter how this virus is modified, its own shell gene is basically fixed and will not change, the diameter of the conventional virus is about 100nm, the smallest virus particle known at present is 17nm, and the largest can reach 300nm, HeLa virus I remember that my father told me before that the appearance of this virus particle is not special." , with a diameter of about 47nm, it is special at the genetic level. ”

When Dai Yiqing said this, he found that everyone had grown their mouths, their eyes widened, and they had a blank expression.

Dai Yijing said embarrassedly: "Is it because I didn't say it clearly enough?" I may not be very well expressed. ”

The fat man waved his hand and said, "Little sister, you can talk about it in something we can understand, I really have enough to hear." ”

Everyone nodded in agreement.

Dai Yiqing said: "I mean this, we usually use a filter or a filter membrane in the conventional water purification, the standard pore size of the filter screen is about 200-300um, but the filter membrane will be finer, can reach the 500-1000nm level, but this is not enough, if you want to isolate bacteria and viruses, we can use ultrafiltration membranes. The rated pore size can reach about 0.0001-0.0020um, that is, the 1-20nm level, the particles of Hela virus are larger than this pore size, we can use ultrafiltration machines to filter the water source, and then purify the water quality. ”

Finally, she added: "Although this method will be slower, as long as the ultrafiltration membrane is not damaged, our drinking water should be fine." ”

Chen Yang couldn't help but open his mouth wide: "Qinqing, this is all like yourself?" ”

Dai Yijing nodded embarrassedly: "My method is a bit stupid, but as long as I can find the machine, I should be able to achieve my goal." ”

The fat man suddenly slapped the table: "Who dares to say that our little princess is stupid in the future, Lao Tzu will be the first to kill him!" ”

Wen Ying also woke up from the shock, and couldn't help but look up to Dai Yiqing a little, she nodded and said, "Qinqing's method is feasible, we are worth a try!" ”

Dai Yiqing suddenly said: "Actually, I have a second method that is also very simple, that is, to use a still to distill a clean water source, but I don't know the temperature resistance of the reconstituted DNA structure of the HeLa virus, so I can't guarantee the success of this method 100%, compared to the first method, this is even a backup plan!" ”

The fat man couldn't help but give a thumbs up: "Listen to you, what a modest and smart girl, fucking cheap Chen Yangbai picked up such a daughter, and I was so envious of it." ”

Dai Yijing smiled embarrassedly at what he said, and when he looked up, Chen Yang also gave Dai Yiqing a thumbs up.

Zheng Jing suddenly said, "I have something I don't understand. ”

The two methods mentioned by Jingqing should be common filtration methods in the life sciences, so why did the toxicologists and the Institute of Public Health in Jiangbei City, or even the Disease Control Institute, not respond? You must know that even if it is one of the methods, as long as it can be used properly to purify the water, the virus will not spread so quickly! ”

Zheng Jing looked at them and said.

Wen Ying: "I think I should know the answer to this question. ”

"On June 6, 2264 A.D., that is, after Helena Life Science Co., Ltd. poisoned the Jiangbei Water Plant, to September 25, the new era was opened, which is almost three months, and the HeLa virus has three characteristics that have caused the current situation, the first is that it spreads extremely fast, and soon after the poisoning, the number of hospital outpatients has increased exponentially, and at first everyone thought it was just a routine infectious disease."

"The second feature is the collapse of internal systems, the Institute of Virus Defense and Control, the National Public Health Research Institute, the Institute of Toxicology, these life scientific research institutions were destroyed by internal forces almost at the same time as the outbreak of the virus, and the speed of collapse is like a river bursting its banks, and there is no time to react at all."

"The third and most important point is that the entire Jiangbei City and even Snow Country did not raise their vigilance against the ravages of this virus in time, but only treated it as a routine high-susceptibility epidemic virus, and by the time the abnormality was discovered, it was too late."

"On the whole, any of these three points is enough for the enemy to take advantage of, not to mention the combination of these three points, which also reflects from the side how long the boss behind Helena's company has been planning for this game of chess."

Wen Ying's analysis is very thorough, so thorough that even if you are not in it, you can feel a sense of powerlessness, and now that I think about it, an S-class city with a population of more than 50 million has been infected with the virus in three months, and all the defense systems have collapsed, which is really terrifying.

Considering it from this point of view, it is very clear that Wen Sakura has something that she has not said.

Snow Country must sacrifice Jiangbei City, this is almost a sure thing, you can make a hypothesis, if the Snow Country forces let the virus carriers in Jiangbei City escape, then in what short time will Snow Country fall?
