After getting Chen Zheyu's call, Lin Han quickly got in touch with him.

"Is it Professor Chen Zheyu?"

Chen Zheyu pronounced his words very clearly, a bit like an announcer: "Yes, I think you should be the person in charge of the Vientiane Sewage Plant, the general story, Shuqing has already told me." ”

Lin Han said, "Then what is your opinion?"

"What kind of materials do you need?" Chen Zheyu didn't say clearly.

"It has the force of law and can explain the advanced nature of the technology and its great value. ”

"Are you going to go to court?"

Lin Han did not hide it: "Someone was instructed to come to our factory to steal secrets, and now it has been handed over to the public security organs for processing, and the human and material evidence are there, but a proof of processing technology is also needed." ”

When Chen Zheyu heard this, he seemed to think about it for a while: "I am very curious about some of the technologies of the Vientiane Laboratory, especially this microbial treatment technology, and I have always been puzzled. I can't even see the rationale for its use. ”

As the best type of scientist in China, with his knowledge level and vision, he is definitely not something that others can fool casually.

Lin Han's understanding of microorganisms is only at the high school level, of course, he knows that if he says too much, he will lose, and even if he says: "I am not convenient to disclose the specific content to you, and I myself know nothing about it." But one thing can tell you that our laboratory currently has some special technologies that can greatly affect the physiological state of microorganisms. ”

Chen Zheyu hurriedly asked, "What is the intensity of the impact?"

Lin Han was a little empty: "Hmm...... It can greatly increase the metabolic rate and reproduction rate of microorganisms. ”

"What!" Chen Zheyu was a little shocked and speechless for a while.

"Professor Chen?"

Chen Zheyu reacted at this time and hesitated: "If Vientiane Laboratory really has such technology, I have a reluctant request." ”

You say. ”

"Not long ago, when I went to CUHK for an exchange, I received a commission to cultivate a batch of new Wolbachia for CUHK and the Dongguang Provincial Health Bureau. Chen Zheyu said slowly.

"According to our initial plan, after cultivating a new type of Wolbachia, we will infect mosquitoes to stop the dengue virus from multiplying in mosquitoes, and then stop the spread of dengue fever in the human population......"

Dengue fever is an infectious disease that is mainly endemic in tropical and subtropical regions, such as Dongguang Province, Hujian Province and Hong Kong Province in China.

In the past few years, a relatively serious dengue fever epidemic occurred in Dongguang Province, which infected tens of thousands of people and caused a small number of deaths, which was quite harmful.

"However, for now, the cultivation of Wolbachia is progressing slowly, and the ideal strain has not yet been developed. ”

Hearing this, Lin Han thought for a while: "What does Professor Chen mean, is he hoping that Vientiane will help cultivate Wolbachia?"

"Yes, since Vientiane can greatly increase the reproduction rate of microorganisms, it should be able to effectively speed up the cultivation of strains. ”

"What's the plan?"

Chen Zheyu thought for a while: "When the time comes, our research institute will hand over the strains that have been cultivated to Vientiane. As long as Vientiane can hand over a large number of mutants to us, we will do the follow-up screening work. ”

Genetic mutations are widespread in the biological world, and the human body is made up of about 50 trillion cells, and thousands of these 50 trillion cells are mutated every day.

In the vast majority of cases, these thousands of mutated genes will be processed by the human body itself, and it is not a big deal.

Sometimes, however, these mutated cells can cause very serious diseases such as cancer, or have some unexpected benefits for the organism.

Of course, mutations are random, and whether it is to gain cancer or benefit, it is a small probability event.

More often than not, these mutated cells die together with some normal cells in the process of being processed, causing a small loss to the organism.

This accumulation of loss is one of the causes of aging in all large organisms.

This kind of genetic mutation that accumulates over time is probably not a good thing for large organisms. However, this is not necessarily the case for microorganisms such as bacteria, which have only one cell in total.

A bacterium is likely to die directly because of a mutation, and it is also likely to gain "superpowers" because of a mutation and become a fighter among bacteria, which is how various "superbugs" come about.

Of course, although the vast majority of superbugs are very tenacious and invulnerable, they actually have no outstanding pathogenic ability.

Superbugs, which have a strong pathogenic ability and are difficult to kill, have not yet emerged. The superbugs that are reported in the news, while not to be ignored, are not worth panicking about.

All kinds of bacteria and microorganisms that are commonly mutated will eventually produce various magical existences that can be used by human beings through continuous screening by artificial.

Lin Han can increase the reproduction rate of microorganisms, which can greatly speed up this process.

As for induced mutation, this one is too simple. The easiest way is to bask in the sun and collect some ultraviolet rays. More than enough to buy an X-ray scanner for high efficiency.

The more complicated screening work is handled by Peking University anyway, and Lin Han doesn't have to think too much about it.

So he immediately agreed: "This is no problem, you send a strain, Vientiane will definitely hand over 100 copies." ”

Hearing this, Chen Zheyu couldn't help but be a little excited: "That's really good." ”

Lin Han smiled: "It's a matter of effort...... However, what are you going to do with my factory's identification materials?"

Chen Zheyu was silent for a while, and then said: "In this way, Vientiane provides me with a data on sewage treatment, as long as it is true data, I can issue a certain certificate for you." ”

"In addition, I will ask a few of my friends to sign the appraisal report together. ”

Chen Zheyu's friend, that must also be a big bull in the field of microorganisms, maybe it's another few Changjiang scholars. This appraisal report is absolutely weighty.

As for handing over a real data on sewage treatment, this is of course a trivial matter.

"Then I'm sorry for you, I'll send the data over today. ”

"Good. ”

After hanging up the phone, Lin Han immediately went to the sewage treatment plant, took a complete and detailed sewage treatment data, marked the effect and rate of sewage treatment in Vientiane, and sent it to Professor Chen Zheyu.

Chen Zheyu's actions were also very quick, and after receiving the data, he quickly made an appraisal report, signed it, and sent it out.

In just two days, Lin Han got this full appraisal report.
