Yang Zhuo was lying on the lawn, panting, his expression a little gloomy.

He was defeated...... Lin Han's ecstatic flying kick made him unable to slow down so far, the arm that blocked was numb, and his chest was also faintly painful.

Although there is a lot of luck in the victory or defeat this time. But a loss is a loss, and for a central guard who protects the leader, there is no reason for failure.

Lin Han walked over at this time and asked, "Do you admit defeat?"

Yang Zhuo lay on the ground, did not speak, and was silent for a while: "Your strength is innate?"

"Any questions?"

Yang Zhuo was silent for a while, then sat up from the ground and sighed: "I never thought that people could have such a physique...... With your physical fitness, just go and train for a week, and I'm no match for you. ”

"If you train for three months, you can get a World Fighting Championship. ”

Lin Han was stunned: "Is there a big gap between you and the World Fighting Champion?"

Yang Zhuo glanced at him: "The gap is not very big, but it can't be ignored...... My number one goal is to protect others, not to win in a fight. ”

Lin Han nodded.

In the impression of many people, the hand-to-hand combat ability of special forces and agents is better than that of professional fighters.

But the actual situation is just the opposite, the single hand-to-hand combat ability of combat athletes is actually higher than that of special forces.

After all, the training content of combat athletes is only fighting, and the training content of special forces, in addition to fighting, also includes coordination, weapons, tactics, and so on.

Generally speaking, top fighters lose more against top fighters with bare hands, one-on-one fighters lose more, and 10 fighters lose more.

Of course, many soldiers have a hobby in fighting, and many combat athletes are also transferred after intensive training, and the two are not distinct.

After the defeat, Yang Zhuo's posture was obviously lowered.

Lin Han didn't choose to press, so he said: "Although you lost, it was also luck for me to win." ”

"That's it, I'll help you pay off the 8 million arrears directly, and you work for me for ten years with a monthly salary of 30,000, how about it?"

Yang Zhuo's heart moved, and he couldn't help but think about it.

The monthly salary is 30,000, which is 3.6 million for ten years, and plus 8 million in arrears, it is 11.6 million...... In this way, it is almost a monthly salary of 100,000, but there are no shares.

The most important thing is that the debt of 8 million can be paid off immediately, which makes him very excited.

Although the creditor gave face and did not urge him to pay the debt, for a responsible person, the feeling of debt is very heavy.

However, it will take ten years to work in Vientiane......

"If you don't want to, I don't force it, decide for yourself. ”

Yang Zhuo thought about it for a while, and finally made up his mind: "Mr. Lin, I am willing to join Vientiane." ”

......

A master duel made everyone unsatisfied, and it took a while before it gradually ended, while discussing in twos and threes.

On the same day, Yang Zhuo became the head of the security section of Vientiane Technology, responsible for the overall security work, and Zhai Yongsheng was directly responsible for the security of the first sewage plant.

In addition to these two people, four more people passed the interview, a total of six people, one more than originally planned.

After the formalities were completed, Yang Zhuo, the former fourth-generation personal guard, became Lin Han's subordinate, and he also signed a ten-year-long "deed of sale".

Lin Han didn't talk nonsense, and quickly paid off all the arrears for Yang Zhuo.

On the first day, a total of 10 security guards were transferred from various branches to carry out security training and gradually strengthen the security force of Vientiane.

It is said that Yang Zhuo's training standards are quite strict, and the security guards who participated in the training camp all complained that Qinglin County had become the sixth war zone in China......

With the addition of this former central security officer, Vientiane's security problem has finally been resolved.

......

The sewage treatment business of Yunzhou City continues to flow to Vientiane, and after Tengyuan, a number of factories have signed cooperation agreements with Vientiane Sewage Treatment Company.

Lin Han had plenty of money, and he didn't have so many scruples about spending money, so he immediately replaced his Mercedes-Benz with a Maybach S worth three million.

Just after buying the car, Professor Chen Zheyu from the capital called him.

After some conversation, Lin Han learned that the Institute of Microbiology of Peking University had sent five samples of Wolbachia and would soon be sent to Qinglin County.

At the beginning, he promised Chen Zheyu that he would provide a large number of Wolbachia variants to Peking University, but now the strains are about to be sent, but it is time to make some preparations in advance.

In order to produce a large number of bacterial variants, in addition to accelerating the rate of bacterial reproduction, of course, a higher mutation rate is required.

Generally speaking, there are four ways to induce genetic mutations, namely physical mutagenesis, chemical mutagenesis, aerospace mutagenesis, and biological mutagenesis.

Biological mutagenesis refers to the use of bioengineering technology to edit and modify the genetic material in cells to promote mutation. This kind of mutagenesis is very demanding, and at present, human beings can only be said to have mastered a little fur.

Aerospace mutagenesis refers to the use of space means to obtain special environments such as cosmic rays, microgravity, and micromagnetic fields, which leads to large-scale genetic mutations in embryos and cells.

Every time a spacecraft is launched, it will carry at least some plant seeds, which will be mutated and screened to obtain people's ideal plant bodies...... This is also a very important part of the aerospace field.

Chemical mutagenesis is the use of various chemicals to cause mutations, which is more common.

For example, middle school textbooks mention a substance called "colchicine", which can be extracted from colchicine with ethanol, and ordinary people can also play with it.

Physical mutagenesis mainly refers to the induction of genetic mutation of cells through electromagnetic radiation and particle radiation, with high efficiency, and the most widely used is gamma-ray mutagenesis.

However, gamma rays are not easy to do, Lin Han thought about it, and finally decided to use X-rays, the effect is a little worse, but it is much more convenient and safer.

The X-ray machines that can be bought locally and have good effects are basically medical type, and if you want to buy them, you need certain qualifications and report to the relevant departments.

This is not a trouble for him, firstly, he has some contacts with various local departments now, and secondly, the requirements for buying a medical X-ray machine are not high, after all, tens of thousands of yuan of things are more than enough in the name of Tianhu Village Health Center.

So, on the one hand, Lin Han donated 100,000 yuan of medical equipment to the Tianhu Village Health Center, and on the other hand, in his name, he ordered several medical X-ray machines and some anti-radiation equipment.
