Although this is what Li Moyang calls "an easy-to-understand expression", it is indeed a little vague and difficult for them to understand this concept for a while......

Li Moyang sighed, thought for a while, and said: "Let's put it this way, we used far-infrared observation technology to detect the complete and fresh fingerprints existing at the scene by irradiating various far-infrared spectra at the scene of the crime, and of course, this is also combined with the system's random screening ability......

Therefore, just now I let the comrades of our Municipal Public Security Bureau try this function, it can be said that the effect is relatively good, although the equipment I brought is the test equipment we used for the first time, but the effect is still obvious, we have in many places should not exist there fingerprints. "

As he spoke, Li Moyang turned on the projector in the conference room, dropped the projection screen, and used the projector to present the list of fingerprints that could be listed by the computer's brainpower, "These are all suspicious fingerprints analyzed by our system, including the fingerprints on the railing outside the toilet window, the fingerprints on the inside of the underground garage door, and the three fingerprints connected together at the bottom of the building pit......"

Li Moyang pointed to the tables listed on the screen with a laser light and explained one by one, "Even, we have a few fingerprints on the color steel plate fence next to the entrance of the construction site, and they are arranged in the order of fingers......"

Speaking of this, Li Moyang could raise his voice and raise his voice, "The appearance of many fingerprints makes me feel incredible, and even small fingerprints that should belong to women appear in the men's toilet...... I really don't know what your factories are doing during working hours...... Ah, even when it's off work, there are some things you shouldn't do, right?"

Li Moyang immediately diverted the topic, causing a burst of laughter in the conference room.

After introducing the suspicious fingerprints that appeared in the list, Li Moyang put away the screen and asked the police officers to resist a fingerprint collector.

"Please tell each other that within 30 minutes, please gather in this conference room, we will collect everyone's fingerprints at a time, if your fingerprints appear in the wrong place, I hope you will cooperate and explain why your fingerprints appear there...... These fingerprints are all fresh fingerprints that have appeared in the past three days, so you probably don't even remember what you have done in the past three days......

After speaking, Li Moyang glanced at the venue, and finally his eyes fell on Dong Huasheng. Dong Huasheng was obviously a little uneasy, he kept tugging at his tie, looking like an ant on a hot pot.

Li Moyang thought for a moment and added, "If you can't explain why your fingerprints appear in places where they shouldn't, then I'm afraid I'll have to ask you to go back with us to investigate." Okay, let's all go and contact our co-workers, oh yes, those who are resting, those who are out, all call back, this is the only chance to exonerate yourself as the owner of these fingerprints, the initial suspect, and save yourself from suspicion. You can come back at any time later and let the device collect your fingerprints, so let's break up for now. "

The people in the venue stood up one after another, and most of them were talking to the people around them, but Dong Huasheng, who looked restless and walked out by himself. Li Moyang's eyes rolled, and he hurriedly stepped forward and grabbed him.

"Boss Dong, wait a minute. Li Moyang looked at Dong Huasheng with a smile, and the latter pretended to be calm, "Uh...... Inspector Li, what's the matter?" Li Moyang continued with a gentle smile, "You're the person in charge of the construction site, I don't think you would mind taking the lead in letting the machine collect your fingerprints." "

All the people who had not yet left the conference room heard Li Moyang's deliberately loud words, and they all stopped, looked at Dong Huasheng, and waited for him to be the first to step forward to do fingerprinting.

Dong Huasheng looked at the circle of people around him, obviously he had no other choice, so he walked to the fingerprint collector with a smile and pressed his ten fingers.

"Okay, thank you Boss Dong for being the first pioneer for us, everyone hurry up and call their co-workers. "

Li Moyang beckoned everyone to leave the conference room, Dong Huasheng wiped the sweat on his forehead and wanted to leave, but was once again stopped by Li Moyang.

"Inspector Li, is there anything else?" "Ah, actually, it's nothing, I just want to chat with you, don't you mind?" "

Looking at Li Moyang's bright smile on his face, Dong Huasheng couldn't be happy, he couldn't figure out what kind of medicine Li Moyang was selling in this gourd. But there is no reason to refuse at the moment, because of He Bin's death, all production activities on the site have been suspended, and he always says that he still has work to do and then walks away.

In this way, Dong Huasheng was dragged by Li Moyang to a living room next to him, and chatted for more than an hour, although he never talked about the case, but Dong Huasheng looked very uncomfortable from beginning to end.

This is exactly the same as Li Moyang thought.

Time passed quickly - although it was a bit torturous for Dong Huasheng, but unconsciously, time slipped away in a hurry for two hours.

"Hahaha, it seems that Boss Dong, you were not an honest master when you were young~~ If you were me, you would definitely not dare to go up and lift someone's skirt directly, hahahaha......"

Just as Li Moyang and Dong Huasheng were chatting about the "glorious deeds" of this old fat man, there was a knock on the door, and a police officer walked in, saw Dong Huasheng and Li Moyang were here, and said with relief: "Hi, Boss Dong, Inspector Li, you are both hiding here, so I can find ...... easily."

Li Moyang stood up and asked, "What's wrong?" Is there something wrong with fingerprint collection?"

"This ...... It's really a fingerprint thing, but I can't say it clearly, anyway, you two come over together, there is something to confirm with you......"

Li Moyang nodded and walked out the door, but Dong Huasheng looked reluctant, as if he didn't want to get up, so Li Moyang simply ran over with a smile and dragged him up, "Oh, Boss Dong, the police uncle has said that there is something to confirm with the two of us, how can you stay here alone? Could it be that you are the murderer~~"

Dong Huasheng waved his hand again and again, his face turned white, "No, no, no...... I want to ...... I want to go to the bathroom......"

Li Moyang was not ready to give him room for mediation, and directly dragged him out of the living room, "Okay, okay, I can't die for a while~~" In this way, Li Moyang dragged Dong Huasheng to the conference room.
