Crime-solving god-level fusion system

This is the genius I want to see! 【4】

The audience was silent for twenty seconds.
Then there was thunderous applause.
“Awesome, I was so excited that I almost crushed two eggs with my backhand!”
“He… is he really a student? Is this the aura and professional quality that a student can have?”
“Don’t say it, he observed it carefully enough, there is indeed a bamboo forest in the southeast of our lecture hall, and there is a ventilation and exhaust fan that is just blocked. You make me think that I really can’t imagine where the criminals would get from the exhaust fan. Get out… After all, there are no exits like doors and windows…”
“Such a terrifying insight… This guy can’t get away…”
On the rostrum, Dong Guohua looked at Li Ze and nodded with satisfaction, “This is the genius I want to see!”
The professors on the side looked at each other with expressions of shock.
“How can a young student in his early twenties possess such a level of criminal investigation thinking?”
“Some old detectives who have been in the police station for ten or twenty years do not necessarily have this level. His performance is really shocking!”
“It seems that in criminal investigation, talent is really important… This child has such a keen insight at such a young age.And criminal investigation thinking, the future is boundless…”
……
After quickly finishing his speech, Li Ze went behind the scenes while looking at the case information in his mobile phone mailbox and said hello to Liu Qing, “I have something urgent, you can go up for me when I receive the award later. ,I go first.”
Liu Qing wanted to stop Li Ze, but thought that he might help the police handle the case, so she didn’t shout any more.
“How did he know that he would win the award…”
Liu Qing looked at Li Ze’s figure in the distance, her seductive, mature face was full of curiosity.
……
Hong Kong Polytechnic University.
The flight attendant was killed in the rental house.
Several police officers were surrounding the house and seemed to be investigating something, while Hao Wei was standing at the corridor window outside the house, smoking a cigarette with a dignified expression.
Da da da.
There was a sound of footsteps.
A police officer brought Li Ze over from the stairs.
“Hao Dui!”
The police officer gave Hao Wei a salute, and then went into the rental house to help investigate.
“Mr. Li, you are here.”
Hao Wei immediately put out the cigarette in his mouth and said, “How was the game?”
“that’s not important.”
Li Ze put on his shoe covers, lifted the cordon at the door and walked in, “You said there was a major discovery, did you mean the footprints over there?”
“Damn it, Mr. Li, you are too amazing!”
Hao Wei followed behind Li Ze, and said with a look of admiration: “You can see it at a glance from such a distance?”
Li Ze ignored Hao Wei’s boast, he went directly to the police officers, squatted down and carefully looked at several footprints with mud on the ground.
“This footprint is new, and I suspect that the murderer may have returned here.”
“This footprint is new, and I suspect that the murderer may have returned here.”
Hao Wei said: “There are several muddy areas on the lawn outside the community. It rained lightly last night. He may have gotten muddy when he passed by the muddy land, so he left such footprints in the house, but the strange thing is that no matter what Whether it is the stairs or the elevator door, no such similar footprints have been found.”
“Is there any surveillance in the community?”
Li Ze asked while observing the soil composition on the footprints.
“No, this is an old community, and the surveillance is still the same mosaic-quality camera from 20 years ago, which has long since fallen into disrepair. Otherwise, our work would not have progressed so slowly.”
Hao Wei said, “Don’t tell me, this criminal is quite shrewd. He deliberately picked this old neighborhood.”
“The dirt in this footprint contains a lot of sand, which means that the person who left the footprints walked through a sandy field or a development area – that kind of place usually stores all kinds of sand piles.”
Li Ze carefully observed the footprints and analyzed them. He waved to the police officer beside him, “Bring a pair of tweezers here.”
The police officer beside him immediately obediently handed him the tweezers tool.
Li Ze carefully picked out some white particles of different sizes from the footprint soil.
After observing for a while, the survey technicians came to the conclusion: “These are magnesium oxide particles, which are the raw materials for smelting magnesium.”
“Magnesium oxide?”
Li Ze frowned slightly.
“Magnesium oxide is usually found in nature in the form of periclase, like this pure granular magnesium oxide, which is usually processed by chemical plants.”
Hao Wei said thoughtfully: “So, this person has walked past a chemical factory that smelts magnesium metal!”
“Do not.”
Li Ze shook his head and said, “Metallic materials like this are usually not scattered on the side of the road at will. If he just passed by, there would not be such a large number of magnesium oxide particles under his feet. This person should be a worker in such a chemical factory. .”
“And if the murderer came here on foot, it means that his factory is not very far from here.”
Li Ze turned his head to Hao Wei and said, “Starting from a five-kilometer radius of the crime scene, it should not be difficult to radiate inward to narrow the scope of investigation and find a nearby chemical plant that smelts magnesium metal.”
“Wrap it on my subordinates.”
Hao Wei patted Hungry and assured him, and then began to give instructions to the police officer beside him.
“After a while, you can take a sample of the footprint soil here, and then do a detailed soil composition survey.”
Li Ze said: “After all, what we can discover is limited. In this case, we still have to believe in the power of science.”
“Didn’t you hear what Teacher Li said?”
Hao Wei glared at the technician beside him.
“Listen…I heard.”
The technician responded somewhat bewildered.
“You didn’t respond when you heard it?”
Hao Wei said angrily.
Only then did the technician react, and nodded towards Li Ze and replied, “Understood, I will sample the footprint soil in a while!”
