Mu Yuan was very angry: "Xiao Tongzi, get out!"

"Master, what's wrong with you?"

Mu Yuan took a deep breath and kept saying silently: Hold it! This is your own system! This is your own system!

But when he thought about the technology he had just acquired, Mu Yuan's heart suddenly became angry.

"What do you mean? You're training me to be a police dog? How about smell identification? Just improve your olfactory sensitivity, right?"

"Master, you are stupid! Just improving the sensitivity of the sense of smell is of no use. When you smell a smell, you can know what it is? And what can you analyze from the smell?"

Mu Yuan's eyes widened like a bull: "That's not the point, okay? In the normal sense, shouldn't smell identification technology rely on instruments and dogs for identification and judgment? With your stupid technology, just let me use my nose.

Go and smell it. You don’t play like this, do you?”

"Keep silent, little one!"

"o(╥﹏╥)o."

Mu Yuan was helpless, this thing was really fucked up.

Originally, it was a good thing that the sensitivity of the sense of smell had improved. After that, I could solve the case myself. When others asked how I solved the case, did I say I smelled it with my nose?

It is estimated that in the future, when everyone solves crimes and conducts tracking, they will not bring police dogs with them, but will bring them with themselves.

This is definitely a stain on my life.

But Mu Yuan also saw that no matter how bad he complained, the system would not change the result. What else could he do?

"Who's to blame? It's your own fault... Who made you mean? The worst thing you can do is never mention this in the future, and no one else will know, right?"

Also, from now on, you must not open gift packages in the toilet, even if you are just washing your hands.

After being comforted like this, Mu Yuan felt a little better.

He took a deep breath, and then...

"vomit……"

He didn't feel anything just now, but when he took a deep breath, he felt like he had fallen into a septic tank, the kind that had been aged for ten years.

Not only that, there is also the smell of lime from the walls, the smell of disinfectant after mopping the floor, the body odor left by people passing by, the smell of sweat, the smell of hand sanitizer...

All kinds of mixed tastes, that's all.

He didn't know how he could distinguish so many smells from his breath, but he could feel it anyway, and what was even more awesome was that he could also tell the year.

After more than ten seconds of this, he finally regained his composure.

"What a guy! It's so exciting, I won't be able to practice deep breathing in the bathroom from now on!"

But this ability is really awesome.

Not only did I smell the smell just now, but I could also tell what kind of object the smell was emitting and when it was emitted. For example, there was a kind of perfume smell, which was left from 10 to 12 o'clock yesterday morning. Although

There was only a trace of scent left, but Mu Yuan's nose, which was sharper than a dog, was able to sniff it out.

"With this skill, solving crimes and arresting people is not as easy as drinking water?" Mu Yuan was intoxicated with himself.

It smells so good...

However, he also knows that things are not that simple, and there are still certain limitations to things like breath.

The reason why I can smell so much smell in the bathroom is because it is a closed space and the smell does not spread easily.

In the open area outside, the odor will not remain for so long. Moreover, weather such as rain, snow, heavy fog, etc. will also have an impact on the odor residue.

…

Sitting back on the chair in the duty room, Mu Yuan felt itchy.

It's like Sun Wukong who has just learned the seventy-two transformations and always wants to find someone to show off.

Of course, Mu Yuan didn't want to show off his scent identification skills in front of him, but wanted to solve the case.

"Brother Wu, when did that serial case just happen last?"

Xiao Wu's name is Wu Dechang. He is in his mid-twenties and a veteran. He has worked as an auxiliary police officer at the Qinglong Street Police Station for four years, so he is considered a veteran.

Upon hearing Mu Yuan's question, Wu Dechang, who was browsing the web, quickly looked up and looked outside, and whispered: "Don't discuss this case randomly. The leader has told me to keep it confidential."

"Why?"

"That bastard's targets were all minors."

Mu Yuan was stunned, but the nameless fire in his heart grew stronger and stronger.

"Scum!"

At this moment, Mu Yuan suddenly understood his father's mood. He had never been so eager to bring someone to justice. Even letting this guy live outside for one more day felt like a sin.

Wu Dechang looked outside again and saw that the people in the reception area had almost left.

"That's right! Although this case is not a big one, the impact is so bad that everyone in the whole society is holding back their energy and is determined to arrest that guy. You don't know how rampant this bastard is. The last time he committed a crime, he chose the location

In the dead end of Qinghua Lane behind our police station. Don't listen to my previous complaints. If there is a chance to catch this guy, I am willing to work overtime."

"I am willing too!" Mu Yuan's eyes flashed with a strange light.

Wu Dechang glanced at him sideways, saying that he could no longer talk for the rest of the day.

Just as he was talking, several people walked in from the door, none other than Director Zhao and three others.

"Brother Zhao, didn't you bring anyone back?" Wu Dechang looked behind Director Zhao and asked.

Zhao Xing'an glared at him and said, "What? Do you think this class deserves too much leisure?"

"How can that be impossible?" Wu Dechang said with a smile, "Didn't I just listen to what you said about a fight, Brother Zhao? I'm already prepared not to sleep tonight."

"In disputes caused by traffic accidents, when we call the police, we sound like the sky is about to collapse, but in the end we just push them a few times and hand them over to the traffic police brigade," Zhao Xing'an explained casually.

Zhou Bin and Liu Xia, who were working as police officers with him, also put down their individual police equipment and went to do other things.

Zhao Xing'an waved his hand and drove Wu Dechang away from the chair, then sat down on it, making the chair creak a few times.

"Xiaomu, the work at this police station is very complicated..."

After a crackling narration, Mu Yuan felt his head pounding.

Finally, Zhao Xing'an said conclusively: "Well, actually, after saying so much, you don't need to remember them all. If you get in touch with them for a while, you will naturally understand."

Mu Yuan was a little confused. He found that Deputy Director Zhao should have the attributes of being a good teacher.

Zhao Xing'an looked at his watch and said: "It's almost time to get off work. Xiaomu, you just arrived at the office today. I guess you still have some unfinished business. I won't keep you on night shift tonight. But you can also have dinner."

If we go further, the canteen in the institute is not bad."

"Thank you, Brother Zhao." Mu Yuan smiled innocently.

…

"belch……"

After leaving the police station, Mu Yuan hiccupped several times along the way.

"The food at this police station is really good. It's countless times better than last night's steamed buns... Well, it's also better than the school cafeteria. The most important thing is that it's free."

Mu Yuan pouted, but his eyes kept looking around.

"Qinghua Lane!"

He saw a street sign and his eyes suddenly lit up.

I strolled in casually and saw that the alley was not very wide, with tall trees growing on both sides. It could be seen that the alley had been there for many years.

Mu Yuan carefully observed his surroundings, searching alley after alley.

"It's a dead end... this isn't... this is the entrance to the community... Huh? There is a high wall at the end of this alley, that's right."

Mu Yuan quickly walked into the alley.

The torn-off small advertisements on the wall look particularly thick, and coupled with the dark blue bricks, it gives a full sense of history.

This should belong to the lighting area between the two buildings. The high wall was newly built behind it and belongs to the wall of the community behind it.

When he reached the end, Mu Yuan found a corner inside, less than four meters deep, and then there was no way out.

"This is a really good place to do evil."

Mu Yuan took a deep breath.

"Damn it, the smell of perfume is so strong, and there is still alcohol left. Is this intentional?" Mu Yuan couldn't laugh or cry.

In fact, the smell here is not that strong, and even normal people can no longer smell these smells. But Mu Yuan has a good nose. With a deep breath, even if only a few odor-bearing molecules enter the nostrils, he can distinguish them.

"Well... Director Zhao! It seems right. He should have led the police team at that time. It should have been yesterday morning... Unfortunately, the aura is a bit weak. I don't know if the aura left by the previous suspect is still there.

.”

"Huh...huh..."

Mu Yuan frowned. Apart from Director Zhao's breath at this time point, he could no longer smell anything valuable.

"According to the law of breath residue, the air remains for the shortest time. If you stay in one place for a long time, then the strongest residual smell should be...the ground."
To be continued...
