There were professionals, and the speed of handling the case at the scene became faster, and several criminal policemen wore gloves and walked around the room to find clues.

Yuan Si originally thought that when her colleague came, she would be able to withdraw, but she saw that there was a colleague here sweeping the ground with a small brush, and a colleague over there was a colleague measuring with a ruler, which was very fresh for the little policeman who had never been to the scene of the crime.

"What are you doing here?" Yuan Si curiously approached a colleague with a brush and asked in a low voice.

The criminal policeman with the brush had a good temper, and he really explained it to Yuan Si.

"Haven't you seen it? I'm taking fingerprints and footprints. The killer doesn't necessarily leave obvious footprints or fingerprints, in this case, we have to find a way to let the clues hidden in the shadows pop up on their own......"

"Naturally secreted by the body, such as the fingerprints of sweat strokes, we can't see them with the naked eye, what I do now is to find out if there are such fingerprints. The criminal police comrade explained that the work in his hand had not fallen, and the small brush was still flying up and down.

"Can you just swipe it to find those fingerprints you said?" Yuan Si still didn't understand.

"Of course not, I'm just the first step. Comrade Criminal Police raised the small brush in his hand, "When traces are found, other methods are still necessary to make these hidden evidence visible, see it, this is powder, sprinkle this thing on it, any hidden traces of crime will be hidden." Comrade Detective held up a small bag behind him.

Of course, he is exaggerating when he says this, the collection method of footprints and fingerprints is not only this method, some traces of white powder cannot be revealed, so a more advanced magnetic powder method must be used, and if it doesn't work, it will be taken back to the laboratory for chemical treatment to show it, but these high-tech don't need to be told to Xiao Li, a rookie, and she doesn't understand it if she talks too much.

"Oh!" Yuan Si looked suddenly enlightened.

"There are many ways here, if you are interested, I have a few books, and when I go back, I will take them and read them, and increase my knowledge." "Comrade Criminal Police thought that Xiao Li was self-motivated and generously provided his own teaching tools.

"No, no, no, I just happened to see that you were a little curious, let me read the book by myself, but I can't stand it. Yuan Si hurriedly refused, finally she didn't have to go to school, but she didn't want to find something to do for herself.

Comrade Criminal Police smiled and did not speak again.

Yuan Si didn't dare to stay longer, in case she was embarrassed to talk about studying, so she stood up and walked to the side.

In fact, when she first entered this room, she had already used her mental power to scan the inside and outside of this room several times. Under her spiritual power, there is no visible and invisible thing. It's just that she just saw it clearly before and didn't understand the Tao inside, and after listening to the explanation of the little brush criminal police just now, she seemed to have found something amazing.

Yuan Si took advantage of the fact that people were not paying attention, reached out and grabbed a handful of the powder bag behind the small brush detective, then retreated to the door, closed the open door, and raised his hand to sprinkle it on a certain part.

Her actions alarmed several criminal police comrades in the room.

"Hehehe, there seems to be a footprint on it. Yuan Si looked back at several colleagues who were all looking at her, she scratched her head with her other hand embarrassedly, and pointed to the part that she splashed with powder and said.

Fu Yiming looked at Xiao Li, then at the big footprints on the door, turned his head and ordered, "Lao Zhang, go and have a look." ”

"Yes. The little brush policeman walked over with his tools.

Of course, Yuan Si abdicated and made way for Xian, but Xiao Brush's words from the public security left her behind, "Xiao Li, don't go, I see that you are quite talented, come and I will teach you more hands." ”

So Yuan Si, who could have gone home, was left behind.

After everyone had surveyed all the places in the house and the victim was taken away, all the criminal police packed up their tools and prepared to go back.

"Xiao Li, you have nothing to do for a while, then go back to the bureau together, we will have a case analysis meeting when we go back, and you can be regarded as participating in the on-site investigation, so let's participate together." Fu Yiming informed Yuan Si very seriously.

"Yes. Yuan Si also agreed seriously.

At this time, on a certain road in the county, Xiao Fuwen rode a bicycle with the old lady and rushed home.

"Xiaowen, let's just leave Si'er there alone, right?" After walking so far, the old lady still didn't feel at ease.

Just now, the two of them went to the back to wait for Yuan Si, and it turned out that Yuan Si was very interested in learning this and that with others, the old lady couldn't bear to disturb her daughter, Xiao Fuwen was indulgent, as long as his daughter-in-law liked it, he had no opinion. In this way, the old lady thought about it, let's go home first, don't delay the girl's affairs, so Xiao Fuwen said to Yuan Si, and sent the old lady home first.

"It's okay, what's the matter, mother, it's not that you don't know Si'er's ability, and besides, it's not just her, she has several colleagues. It happened to be the top wind, and it was a little difficult to speak, so Xiao Fuwen could only tilt his head sideways and talk to the old lady in the back.

"You just talk, don't look back, in case there's a pebble or branch in front of you and you don't see it, what should you do? The old lady was startled when she saw her son-in-law turn his head, and hurried to stop it.

Xiao Fuwen was speechless, if he could speak when he looked ahead, could he still turn his head sideways, wouldn't he be able to open his mouth against the wind.

The old lady saw that her son-in-law obediently turned to look ahead, and then she continued with confidence: "Si'er has some ability, but what can her ability do in the dead man's house, and she can't catch ghosts." Besides, her colleagues are all big men with heavy yang energy, they are definitely not afraid of this, Si'er is a girl, so he likes to recruit that. ”

Chirping......

Xiao Fuwen pinched the brake with both hands, and his long legs went down, and the speeding bicycle stopped.

"Hey, what are you doing, why did you stop. The old lady was startled in the back.

"Mother," Xiao Fuwen called out helplessly, "The gods and ghosts you just said are all superstitions, don't let me say it now, we are still on the road, let others hear it." ”

The old lady reacted at this time, and her first action was to quickly turn her head and look around, wanting to see if there was anyone around when she just spoke.

Looking at the people around, not to mention people, even there were few flies, the old lady patted her chest and was relieved, "You kid, but you scared me to death, if this is listened to by others, and it is being reported, I will be dragged out to fight at such an old age, then I will not live." ”

"So you can't say such things in the future, mother, it's best not to think about it in your heart. "If you don't get it right, you'll pout baldly.

"Mother knows, isn't she worried about Si'er today, or I won't talk about this. "The old lady is not a fool, of course she knows what to say and what not to say.

Xiao Fuwen saw that his mother-in-law knew that it was amazing, so he got on the bike again.

"Si'er, you don't have to worry, there are so many colleagues here, you must not let her have an accident, after I send you home in a while, I will go to her unit to wait for her, and ensure that she is taken home safely, you can rest assured." ”
