"Don't mention it, buddy, this is a bit back, and I was beaten."

Han Chunming said a word, and immediately grabbed Xiao Yao's shoulder.

"I haven't seen you study for so long, let's have a few drinks."

Han Chunming's mother fried a few dishes and sent them to Xiao Yao's backyard, and the two chatted while drinking, it was a complete coincidence that Han Chunming was beaten last night.

"By the way, Xiao Yao, buddy wants to set up a restaurant by himself, you kid pay more attention and give me ideas."

Xiao Yao smiled and said, "A good chef is better than anything else." ”

Xiao Yao was thinking about Han Chunming's safety problem, the so-called one has two, this time he escaped, next time, to put it mildly, if he happened to have tens of thousands of yuan on him, it was difficult to guarantee that the other party would not take risks.

So Xiao Yao thinks it's better to do something for Han Chunming, after all, people are sincere to themselves, since Xiao Yao ran a passbook Han Chunming will deposit dividends every month, yesterday Xiao Yao was shocked when he went to see the passbook, the good guy has paid more than 20,000 dividends this year.

After separating from Han Chunming, Xiao Yao returned to the Su family, and today I came to see Han Chunming who didn't expect such a thing to happen.

The incident of Han Chunming's beating was taken seriously by the leaders above.

There is no way for Han Chunming to do well in the trade market, which has driven the economy of the surrounding counties.

The leaders demanded that Han Chunming's beating and robbery be seriously dealt with.

Someone actually dared to snatch things, and even injured people, almost breaking the heads of young cadres.

These people must be dealt with severely and severely, and this is a wake-up call.

Originally, this kind of thing had just begun to appear, and it did not attract the attention of others, after all, it was all some petty theft, and there was no big mess.

If something really goes wrong, it's going to be too late.

So when Xiao Yao didn't know it, the security problem around the entire city was greatly improved.

Some people who made small moves were severely punished.

As for the gangsters who robbed Han Chunming, because they robbed ten yuan, the lightest one was also sentenced to three years in prison.

Han Chunming was surprised when he heard the news on the street.

The problem was solved so quickly, and he was still grateful to the police for their efficiency.

Xiao Yao didn't know the changes outside, and he spent a pleasant holiday with Su Man.

When he was about to return to the research institute, Xiao Yao had been thinking about what weapons were more portable and non-lethal for the past two days.

As for the gun, not to mention, this is a controlled item, and I don't want to go to the bureau to see Han Chunming.

So I discussed with the system to get a small prop for self-defense, it's best not to see blood, and then it should be useful and be able to subdue the enemy as quickly as possible.

The system directly gave him two words and said: "You kid is really boring." ”

Then throw him a manual of self-defense toys.

Xiao Yao opened it and flipped through it, there were a lot of things in it, the marble gun had a certain striking ability, there were electric batons, and there were also hidden swords and the like.

Xiao Yao felt that these things were not suitable, but the electric baton was barely okay, if Han Chunming was not well controlled, what should he do if he got electricity?

The scene of foaming at the mouth is funny when you think about it.

"Then you're looking at this one." The helpless voice of the system sounded.

Xiao Yao continued to rummage through the books, and finally found a more suitable thing, a sound wave transmitter.

A circular transmitter similar to a small radar reception.

According to the introduction, people can be unable to hear for a short time, dizzy, and lose control of their body.

"That's good." Xiao Yao's eyes lit up.

"This thing is simply an invisible secret weapon that hurts people, but it is much stronger than the secret weapon of the Tang Sect."

"This is not a hidden weapon, this is a scientific product." The system said solemnly.

"The hidden weapon is also a scientific product, after all, his launch needs power, and the launch direction and orbit are related to dynamics, so everything about force is related to science, isn't it." Xiao Yao said mischievously

The system didn't refute it, whatever the host said

Xiao Yao began to look at the manufacture of this weapon seriously, and after reading it, he felt a little emotional.

Don't look at it as a small thing, there are quite a lot of doorways in it, not to mention anything else, just this sonic attack, it's quite complicated to achieve.

If it's something else, you can also pay attention to it and make a four-like one, this thing can't do it, if the sound wave is weaker, it won't have that effect at all.

So be sure to understand the principle inside, as well as the materials needed.

Fortunately, he knew that there was a project in the institute that seemed to be studying sound waves, but it was just in its infancy.

For the sake of Han Chunming's life safety, Xiao Yao felt that this should be taken seriously, and it would be too late to call himself to the banquet one day.

So after work the next day, Xiao Yao approached Professor Chen, hoping to participate in the acoustic research project and study for a while.

Professor Chen was surprised: "Why are you suddenly interested in this, this project is still in its infancy, and you can't learn anything in a short period of time." ”

"I've been interested in this lately and want to see it, and I think my energy can take care of it, the most important thing is that I saw something related when I was flipping through a book recently, and I think sound waves are amazing, just like sunlight fluctuations." Xiao Yao explained

A good thinker is naturally a source of relief for Professor Chen.

He took a closer look at Xiao Yao, a vigorous young man, the road ahead is still very long, while he is still young, he can be a little willful, see more, learn more, and get in touch with other things.

"Then I'll talk to Professor Xu from sound wave research, but whether Professor Xu is willing to let you participate or not is not necessarily." Professor Chan quipped

In the afternoon, Professor Chen brought the news that Xiao Yao wanted

Fortunately, Professor Xu had heard of Xiao Yao, a young genius, and admired Xiao Yao's talent very much.

Hearing that Xiao Yao wanted to study sound waves, naturally there was no unwelcome, maybe this genius boy could discover the principle and reduce everyone's detours.

Xiao Yao followed Professor Chen into Professor Xu's laboratory.

"This is Xiao Yao, it just so happens that we are also doing it from scratch, and you are also learning from scratch, but no one dislikes anyone."

Professor Xu's joke relieved Xiao Yao of a lot of burden.

"Thank you professor for being willing to take me, I will definitely study hard with you." Xiao Yao said gratefully

Professor Xu said with a smile: "A month's time, you will be given a month at most, this month you learn the basic knowledge of sound waves, and then we will officially start the pilot project." ”

Xiao Yao pondered for a month, and felt that he could complete his own research, after all, the materials here are all ready-made, and he can't really make any sound wave research, just make a small sonic gun.
