Chapter 813

When Qin Lang and Tao Ruoxiang went out, the two tongued policemen were still vomiting desperately, because two pieces of rat shit just stuck to their throats.

Since Wei Han, the master of concealed weapons, was turned into a poisonous slave, Qin Lang's concealed weapon Kung Fu has also increased.

"What the hell are you doing?" After getting on the bus, Tao Ruoxiang asked Qin Lang.

"Of course." Qin Lang said, "Whoever dares to bully my aunt Tao, I will clean up who!"

"Er..." The moving color flashed in Tao Ruoxiang's eyes, then she turned the topic aside and said, "why do you call me aunt Tao again? Do you think I'm old?"

"Aunt Tao is still young and moving. However, if I call you auntie, I feel a sense of excitement to break through the taboo. "

"Pervert!" Tao Ruoxiang spat at Qin Lang and said, "well, you'd better tell me how to catch the thief now!"

"Very simple." Qin Lang felt a piece of rat excrement in his pocket, "this is the clue. Now, drive to the river and find a place with a sewer outlet. "

Tao Ruoxiang nodded, because the road was a bit congested, and Tao Ruoxiang simply played the siren. Anyway, he was also handling the case seriously. Of course, it was not illegal to play the siren.

However, looking at Qin Lang's excited face, Tao Ruoxiang was very puzzled. It seems that since she met Qin Lang, she has become so no longer a stick to principle. It seems that she has become "bad".

"This is not a good phenomenon." Tao Ruoxiang reminds himself in his heart.

After driving the police car around for a while, they found that they had actually arrived near the barbecue street again. Tao Ruoxiang parked the police car on the Bank of the river, and then waited for Qin Lang to "cast the law".

To be honest, Tao Ruoxiang doesn't believe that Qin Lang can find any clues with a piece of rat shit, but she has to believe it, because what Qin Lang does next is totally beyond her imagination:

Qin Lang found a small smooth hole around the hole in the river bank, which is sure to be a mouse hole. Barbecue street, where there are rich bones and scraps left on the ground, is also a paradise for mice. There are many mouse holes under the riverbank, flower bed, lawn and tree roots. Even in the daytime, some mice can be seen drilling up and down.

Although under the unified arrangement of Aiwei society, the District Management Committee here also pretended to carry out deratization activities, but it was nothing more than to sprinkle rat drugs on the lawn. But the key mouse is not stupid. Melon, in the evening, there will be a lot of crispy and delicious meat bones on the ground and even some barbecue on the ground, which is delicious for the mouse. In such a case, how could the full rats be interested in those rat drugs.

Qin Lang's "whistle" rang.

A moment later, from the cave of the river bank, groups of mice came out, and the large number of mice saw Tao Ruoxiang's scalp was numb. However, she did not interfere with Qin Lang's behavior. Curiously, she found that these mice came out, but she didn't run around, just sniffed the rat excrement Qin Lang had left on the ground. After each mouse has sniffed the rat excrement, it will return to the ground cave.

"Qin Lang, do you want these mice to find out the smell of this rat excrement?" Although something happened in front of her is beyond her imagination, her thinking of handling cases is still very clear.

In addition, Tao Ruoxiang has seen Qin Longzhao's snake skills, so it's no surprise to call rats and cockroaches.

That's what it means.

"That's right." Qin Lang nodded and smiled, "since the other party left this piece of rat shit as a clue, we just need to follow this clue to find it. Anyway, for this mouse, we need to see the rat alive and the rat dead

Qin Lang's method was very effective. About half an hour later, the "culprit" appeared.

It's just a very ordinary mouse. It sniffs and sniffs in front of this piece of rat shit, and then it stays here. It seems that it's ready to be frank and lenient.

"That's it?" Asked Tao Ruoxiang.

"That's it." Qin Lang nodded, "the criminal is already in front of you. Now what are you going to do?"

Qin Lang's serious expression made Tao Ruoxiang smile, and then he said with a straight face: "this guy is only an accomplice, now we need to find the main plot through it, I don't know what else you can do?"

"Then let it find the mastermind." Qin Lang said, "although you haven't found any other evidence at the crime scene, it can only show that the mastermind is too cunning. I'm sure he must have appeared at the crime scene. Even if he didn't leave any evidence at the scene, he would have left evidence near the crime scene."

"So let's go back to the jewelry store now?"

"Go back." Qin Lang nodded.

They drove back in their car, and the little mouse stayed in the police car as if he were a criminal who had surrendered and was waiting for legal sanction.

When we got to the jewelry store, the two policemen had already left.

Qin Lang dropped the mouse on the ground, and then it began to move, sniffing on the ground, as if looking for something. However, it found nothing on the ground. After a while, it climbed up the ceiling along the light line beside the wall and into the ceiling.

I heard the sound of the rope in the ceiling.

After a while, the mouse seemed to have crawled to another place. However, Tao Ruoxiang is not worried that he will run away, because if he wants to run away, he should have run away.

Moreover, Tao Ruoxiang already knew Qin Lang's way: find the rat who committed the crime through rat excrement, and then find the perpetrator through this mouse.

In fact, it's a very simple investigation logic. It doesn't need a high IQ, but the difficulty lies in that other people can't control these rats at all, let alone let the rats "confess" to actively find out the behind the scenes murderer.

After waiting for about 20 minutes, the mouse finally came back here again, with a small piece of cloth in its mouth. There is no doubt that the cloth should have been left by the criminal. But I didn't expect that the criminal could climb into the ceiling and the ventilation channel. It seems that this guy is not easy.

Tao Ruoxiang cut off half of the cloth and kept it as evidence. As for the other half, Qin Lang will continue to trace the criminals. Because according to Qin Lang's idea, there is a smell of a criminal on this half piece of cloth. This person can use the mouse to steal, and Qin Lang can use the mouse to find him.
