Chapter 419

Of course, Qin Lang doesn't know where these crisscross sewers lead. However, Qin Lang leads the way by drilling mountains and mice. He doesn't need to worry about going into a "dead end". But Qin Lang is not sure whether he can escape from Anrong city under the encirclement of Ye's family and six gates and win the gamble with the old poison.

However, half an hour later, Qin Lang suddenly heard a strange beep, as if it was from a machine. After hearing this sound, Qin Lang just felt a little bored, but the mice around him became very restless, even a little restless and scared!

"Why, what is it!" Qin Lang couldn't help but wonder.

A moment later, a word came to Qin Lang's mind: sound wave mousetrap.

Qin Lang once heard from his father Qin Nan a few years ago about the sound wave mousetrap. He said that there was a project about the ultrasonic mousetrap in their research lab. according to their research results, the ultrasonic wave can have a corresponding impact on many animals, as well as rats. Therefore, their research office has drawn up such a project and received some scientific research funds. It is said that the old professor in charge of the scientific research project has received more than 4 million project funds. However, although the old professor is the project leader, the actual researcher is Qin Nan, the assistant and several graduate students led by the old professor. Of course, this is the hidden rule in the University, but all professors and academicians are only responsible for the project, but in fact, they seldom spend time on the project. Specific research and operation are handed over to these assistants with low wages and low-cost graduate students. Of course, most of the project funds will eventually fall into the pockets of these professors and academicians.

If the project is successful, these assistants, graduate students and even a reputation of participating in the opportunity research can not be obtained. This is the sad point of domestic academic research, which makes many talented researchers have to choose to live abroad.

Of course, Qin Nan, Qin Lang's father, is a different kind. The reason why Qin Nan is an alternative is that since she knew the hidden rules in the University, she resolutely and simply gave up the promotion of Professor, and was willing to devote herself to the laboratory and work with the animals and plants and the bottles and cans in the laboratory, because he just wanted to stay away from those dark and corrupt activities. Qin Nan, Qin Lang's father, almost did not covet fame and wealth. That's because he really liked the profession and he had a wife who shared the same interests with him.

As a man, it's very important to choose a wife. A money mother-in-law can destroy a man's ideals and confidence, while a money mother-in-law plus a money wife can completely destroy a man. Although Qin Nan has been "stepping on the spot" all these years, his wife Xue Yinglian never put any pressure on her. Instead, she tells him not to worry about the gains and losses of fame and wealth. It's the most important thing to be down-to-earth and happy to do what she likes. It is because of a wife who understands himself and a son who is "sensible", that Qin Nan can quietly put into his research. Although the research results of these years have been "stolen", Qin Nan doesn't care about these, because in these scientific research, he really feels his own happiness.

It seems that there are some people selling the ultrasonic mousetrap on the market, but Qin Lang has done experiments on his own. The so-called "patent" and "famous brand" products are all fake. These so-called ultrasonic mousetrap are useless for mice. Even Qin Lang once put the ultrasonic mousetrap beside the experimental mouse, which is useless However, he was eating with ease.

However, at this time, the ultrasonic mousetrap used by these people is real, Qin Lang can be sure. Qin Lang didn't know if it came from his father's lab, but there was no doubt that it worked. Many mice were already panicking. Although Qin Lang can continue to use insect flute to suppress and drive these mice, but because of the influence of this ultrasonic mousetrap, these mice become very frightened and flustered, which makes Qin Lang drive them not so smooth.

Qin Lang's burrowing rat, by contrast, was much calmer. Although the ultrasonic mousetrap had some effects on it, it didn't make it panic. Fortunately, otherwise, Qin Lang would have to block his ears. Otherwise, without this mountain rat to lead the way, Qin Lang would not want to go out of here smoothly. The sewers under Anrong city are more complicated than the maze in the legend.

However, although the ultrasonic mousetrap is powerful, its quantity is not very large, because it should be a product under development, and the number of such test products should not exceed 10. Although the power of this machine is not small, it is impossible to drive all the rats out of the sewer in the whole city of Anrong!

Unless ye's family and six door people can immediately mobilize hundreds of such machines.

However, with this ultrasonic mousetrap, the monitoring of the sewer by the police and armed police under Ye's command will be much smoother, at least their people can enter the sewer smoothly.

This 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 sewer, Qin Lang's progress became more tortuous and circuitous, because he had to avoid the police.

Although killing a Ye family and a six door catcher is a lesson for the Ye family and the six door catcher, Qin Lang knows that this lesson is far from enough, and it is impossible for the Ye family to be afraid, and even more impossible for the six door catcher to be afraid. It will only inspire their revenge. So if Qin Lang's whereabouts are found, he will inevitably encounter a comparison Ten times as hard as before!

In fact, it's true that ye family's experts are on standby, and all of them are under the unified command of Lin Yuhua of the six gates. Lin Yuhua is invited by Ye Shiqing, and he is also a leader of the six gates. There is no problem in commanding these ye family experts.

But Lin Yuhua's face is still grim. He stands in the hot sun on the street and looks ugly. Today, a catcher is killed, which is a very bad news for him. The competition in the six gates is very fierce. Although he is a deputy group leader now, it is very difficult for him to be promoted to the group leader. Of course, once promoted to the leader of the action team, the authority in hand is also very large. Originally, with Ye family's Secret support, Lin Yuhua might have been promoted to the team leader. But today, he killed a man by himself, which will inevitably cause dissatisfaction of the team leader, and his competitors will take the opportunity to suppress him.
