Chapter 419 Sonic Mouse Repellent

Of course, Qin Lang did not know where these criss-crossing sewers lead, but Qin Lang had a squirrel to lead the way. He did n’t have to worry about going into a “dead end”, but Qin Lang could n’t be sure now whether he could go to Yejia and Liufan. The door's encirclement blocked and escaped from Anrong City to win this gamble with the old poison.

However, half an hour later, Qin Lang suddenly heard a strange buzzing sound, as if it were from a machine. After hearing this sound, Qin Lang just felt a little bored, but the mice around him became very uneasy, even a little bit. Restless, a little frightened!

"Huh, what is this!" Qin Lang couldn't help but wonder.

A moment later, Qin Lang thought of a word in his mind: sonic repeller.

Regarding this sonic rodent repellent, Qin Lang heard his dad Qin Nan mentioned a few years ago, saying that there is a project in their research room about ultrasonic rodent repellent. According to their research results, ultrasound can be used for many What animals should affect is the same for mice.Therefore, their research department drafted such a project and received some research funding. I heard that the old professor in charge of this research project received more than 4 million project funding, but although the old professor is the project leader, but The actual researchers are several assistant graduate students brought by Qin Nan, an assistant and an old professor.Of course, this was originally an unspoken rule in the university, but for the existence of professors and academicians, they are only responsible for receiving the project, but in fact rarely spend time researching this project.The specific research and operation are all handed over to these assistants and cheap graduate students who receive cheap wages.Of course, most of the project funding will eventually fall into the pockets of these professors and academicians.

If the project is successful, these assistants and graduate students who participated in the research of timing will not even get a reputation. This is the sadness of domestic academic research, which makes many talented researchers have to choose to go abroad.

Of course, Qin Lang's father Qin Nan is an alternative.The reason why he is different is because Qin Nan has decisively and completely abandoned the promotion of professors since he knew the hidden rules in the university, and was willing to devote himself to the laboratory with the laboratory animals, plants and bottles. Bottles and cans are together because he only wants to stay away from those dark and corrupt activities.Qin Lang ’s father, Qin Nan, almost did not want to be greedy for fame and fortune. That ’s because he really likes this profession, and he has a wife who likes him.

As a man, it is very important to choose a wife. A money-paying mother-in-law can destroy a man ’s ideals and confidence; while a money-paying mother-in-law and a money-paying wife can completely destroy a man.Although Qin Nan has been "stepping on the spot" for years, his wife Xue Yinglian has never put any pressure on her. Instead, he told him not to care about the gains and losses of fame and fortune, but to do his favorite career down to earth. is the most important.Because of a wife who understands herself and a son who is "sensible", Qin Nan can quietly invest in his research. Although the research results of these years have been "stolen" by others, Qin Nan did not Don't care about this, because in these scientific studies, he really felt his own happiness.

Ultrasonic mouse repellent, this thing seems to be sold on the market, but Qin Lang has done experiments on his own. Those so-called "patent" and "brand-name" products are completely fake. These so-called ultrasonic mouse repellents are basically to mice. It was useless, and even Qin Lang once used this ultrasonic mouse repellent next to the test mouse. It was useless. The mouse was still eating with peace of mind.

However, at this time, the ultrasonic mouse repellers used by these people were genuine, and Qin Lang was absolutely certain.Qin Lang didn't know whether this thing came from his father's laboratory, but there is no doubt that this thing worked, and many mice have begun to panic.Although Qin Lang can continue to use the insect flute to suppress and drive these mice, these rats become very frightened and panicked due to the influence of this ultrasonic rodent repellent, which makes Qin Lang not very successful in driving them.

In contrast, Qin Lang's mountain rat was much more calm, although the ultrasonic rat repeller had some impact on it, but it did not make it frightened.Fortunately, Qin Lang may only be able to block his ears, otherwise Qin Lang would not be able to lead the way, Qin Langxiu wanted to go out smoothly from here. The sewers below Anrong City are more than the legendary maze Be complicated.

However, although the ultrasonic rat repellent is powerful, the number is not very much, because this thing should be a product under development. The number of such test products should not exceed ten, although the power of this machine is not small, but It is simply impossible to drive out all the rats in the sewers of Anrong City!

Unless, the Ye family and the people with six doors can immediately mobilize hundreds of these machines.

However, with this ultrasonic rodent repellent, the police and armed police under Ye Jiayu's monitoring of the sewers will be much smoother, at least their people can successfully enter the sewers.

This also means that Qin Lang's situation is not so good, he must hurry to leave Anrong City.

But because the police strengthened the monitoring of the sewers, this made Qin Lang's advancement more tortuous and devious, because he had to avoid these policemen.

Although killing a Ye family and a six-door catcher before, it was a lesson for the Ye family and the six-door people, but Qin Lang knew that this lesson was far from enough, and it was impossible for the Ye family to be afraid, even less It may fear the people of the six doors and only inspire their revenge, so if the whereabouts of Qin Lang are found now, they will inevitably be hit ten times harder than before!

In fact, this is indeed the case, the masters of the Ye family are already on standby, and these people are under the unified command of Lin Yuhua in the six doors.Lin Yuhua was invited by Ye Shiqing and was the head of the six doors. Naturally, there is no problem to command these masters of the Ye family.

But Lin Yuhua ’s expression is still very serious. He stands under the scorching sun on the street, and his expression is a bit ugly, because today a catcher is killed. This is very bad news for him. The competition in the six doors is very fierce Although he is now a deputy team leader, it is very, very difficult to promote to team leader.Of course, once promoted to the action team leader, the power in hand is also very, very large.Originally, with the implicit support of the Ye family, Lin Yuhua was likely to be promoted to team leader, but today a person died in private action, which will inevitably cause dissatisfaction with the team leader, and his competitors will certainly take the opportunity to suppress him .
