Of course, Qin Lang didn't know where these criss-crossing sewers led, but Qin Lang had a mountain rat to lead the way, so he didn't have to worry about entering a "dead end", but Qin Lang couldn't be sure now whether he would be able to escape from Anrong City under the siege and interception of the Ye family and the six gates, and win this gamble with the old poison.
However, half an hour later, Qin Lang suddenly heard a strange buzzing sound, as if it was from the machine, after hearing this sound, Qin Lang just felt a little bored, but the rats around him became very restless, even a little restless and a little frightened "Hey, what is this" Qin Lang couldn't help but be surprised.
After a while, a word came to Qin Lang's mind: sonic mouse repellent.
Regarding this sonic mouse repellent, Qin Lang heard his father Qin Nan mention it a few years ago, saying that there is a project in their laboratory about ultrasonic mouse repellent, according to their research results, ultrasound can have an impact on many animals, and the same is true for mice.
I heard that the old professor in charge of this scientific research project received more than 4 million project funds, but although the old professor was the person in charge of the project, the actual researcher was Qin Nan, an assistant, and several master's students led by the old professor.
Of course, this is the unspoken rule in the university, but all professors and academicians are only responsible for taking on projects, but in fact, they rarely spend time researching this project.
The specific research and operations are handed over to these assistants who receive cheap salaries and cheap graduate students.
Of course, the vast majority of the project funds will eventually fall into the pockets of these professors and academicians.
If the project is successful, these assistants and graduate students who participate in the timing research will not even get a reputation, which is the sadness of domestic academic research, so that 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 since Qin Nan knew the unspoken rules of the university, he decisively and simply gave up the matter of being promoted to professor, and was willing to devote himself to the laboratory, and the animals and plants in the laboratory and the bottles and cans, because he just wanted to stay away from those dark and corrupt things.
Qin Lang's father, Qin Nan, almost really did not covet fame and fortune, that was because he really liked this profession very much, and he had a wife who was like-minded with him.
As a man, it is very important to choose a wife, a mother-in-law who worships money can destroy a man's ideals and confidence; And a money-worshipping mother-in-law and a money-worshipping wife can completely destroy a man.
Although Qin Nan has been "standing still" all these years, his wife Xue Yinglian has never put any pressure on her, but told him that he doesn't have to care about the gains and losses of fame and fortune, and the most important thing is to do what he likes in a down-to-earth and happy way.
It is precisely because he has a wife who understands him and a "sensible" son that Qin Nan can quietly devote himself to his research, although the research results over the years have been "stolen", but Qin Nan doesn't care about these, because in these scientific researches, he really feels his own happiness.
Ultrasonic mouse repellent, this thing seems to be sold on the market, but Qin Lang has done experiments himself, those so-called "patent" and "brand" products are all fakes, these so-called ultrasonic mouse repellent devices are useless to mice, and even once Qin Lang put this ultrasonic mouse repellent next to the experimental mouse It was useless, and the mouse was still eating with peace of mind.
However, at this time, the ultrasonic mouse repellent used by these people was genuine, and Qin Lang was completely sure.
Qin Lang didn't know if this thing came from his father's laboratory, but there was no doubt that this thing had an effect, and many rats had already begun to panic.
Although Qin Lang could continue to use the insect flute to suppress and drive these rats, because of the influence of this ultrasonic mouse repellent device, these rats became very panicked and flustered, which made Qin Lang's drive not very smooth.
In contrast, Qin Lang's drill rat is much more "calm", although this ultrasonic mouse repellent has some impact on it, but it does not make it frightened and overwhelmed.
Fortunately, otherwise Qin Lang would probably have to plug its ears, otherwise without this drill rat to lead the way, Qin Lang would not want to get out of here smoothly, and these sewers under Anrong City are even more complicated than the legendary labyrinth.
However, although this ultrasonic mouse repellent is powerful, the number is not very large, because this thing should be a product under development, and the number of such experiments should not exceed ten, although the power of this machine is not small, but if you want to drive out all the rats in the sewers of Anrong City, it is simply impossible Unless, the Ye family and the people of the Six Doors can immediately mobilize hundreds of such machines.
It's just that with this ultrasonic mouse repellent, the monitoring of the sewers by these police and armed police under the command of the Ye family will be much smoother, at least their people can enter the sewers smoothly.
This also means that Qin Lang's situation is not so good, and he must hurry up and leave Anrong City.
But because the police have strengthened the monitoring of the sewers, this makes Qin Lang's progress more tortuous and circuitous, because he must avoid these policemen.
Although killing a person from the Ye family and the catcher of the Six Doors before could be regarded as a lesson to the Ye family and the people of the Six Doors, Qin Lang knew that this lesson was far from enough, it was impossible to make the Ye family feel afraid, and it was even more impossible to make the people of the Six Doors feel afraid, it would only inspire their revenge, so if Qin Lang's whereabouts were discovered now, he would inevitably encounter a blow ten times more violent than before And in fact, it is true, the masters of the Ye family are already on standby, and these people are all under the unified command of Lin Yuhua of the Six Gates.
Lin Yuhua is the person invited by Ye Shiqing, and he is also the head of the six doors, so it is naturally no problem to lead these masters of the Ye family.
But Lin Yuhua's expression is still very grim now, he is standing under the scorching sun on the street, his expression is a little ugly, because a catcher has died today, this is very bad news for him, the competition in the six doors is very fierce, although he is now a deputy team leader, but it is very, very difficult to be promoted to team leader.
Of course, once promoted to the head of the action team, the authority in his hands is also very, very large.
Originally, with the secret support of the Ye family, it was possible for Lin Yuhua to be promoted to team leader, but today he killed a person in private action, which will inevitably cause the dissatisfaction of the team leader, and his competitors will inevitably take the opportunity to suppress him
