Coroner Coroner

Conan, who had half of his body stuck into the blockade, was even more stunned:

He suddenly discovered that his opponent in the reasoning competition this time...

It seems to have become... Xiaolan?

Chapter 101 Detective Xiaolan

Can Xiaolan solve the case? !

Conan couldn't help being a little surprised:

It's really not that he looks down on his childhood sweetheart... The main reason is that Xiaolan shouldn't be an intellectual hero at first sight!

It's just that after a day of lessons, a girl who only knows how to punch can solve the case?

Is Lin Xinyi so relieved to leave the important matter of human life to Xiaolan?

Not to mention that Conan is worried, Xiaolan herself is also worried:

"Mr. Lin, me, can I do it too?"

The pressure of investigating the case suddenly fell on her half-baked shoulders, and she was very afraid that she would not do well.

"It's okay, you can do it."

"Think about what I taught you, it's enough to solve the case."

Lin Xinyi insisted that Mao Lilan should shoulder the responsibility and solve the case.

On the one hand, he wanted to give Mao Lilan a chance to practice.

On the other hand, he is going to tell everyone in this way:

There is nothing difficult in solving a case. Anyone can do it after learning.

The current public opinion atmosphere highly praises famous detectives, which indirectly gives criminals an illusion:

As long as he can think of a powerful trick and can't meet a famous detective, he can sit back and relax and get away with it successfully.

And Lin Xinyi wanted to break the illusions of these criminals:

Detective?Even if I call an apprentice who has only studied for a day, I can still catch you!

The deterrence lost by the police as a law enforcement agency has to be slowly regained in this way.

Anyone who wants to commit a crime in the future must first decide whether he dares to go to jail.

"remember--"

"Don't be misled by criminals' blindfold, we don't need to play the kind of game that detectives would play."

"Miss Mao Lilan, think about what I said about Roca's Law of Exchange."

Lin Xinyi finally encouraged and reminded.

And Mao Lilan thoughtfully recalled Roca's law of exchange, which is the theory created by French forensic scientist and criminologist Edmond Roca:

"Where two objects come into contact, there will be a transfer phenomenon."

In criminal investigation, there is no need to solve tricks at all.

You only need to be able to find the things left by the murderer from the scene, and find the things he took away from the murderer from the scene, and you can get the answer directly.

"I understand…"

Mao Lilan thought for a while, and finally thought of something.

She turned around and asked the police officer who had just come to report the monitoring content with a serious face:

"When you watched the surveillance video, the murderer should have blood on his body, right?"

"Of course there is!"

"The guy lifted the dead man from the ground to the highest point with one hand, and stabbed him with a sword in the other hand."

"When the sword pierced through the neck, it was like digging through an oil well... The blood spurted out a big basin, and sprayed the murderer in the face on the spot."

"Just like that wall, the murderer looks like he just got out of the pool of blood, and the armor is covered in blood."

Looking at the wall that was almost completely stained red with blood, the police officer described the contents of the surveillance with lingering fear.

"That's fine."

Mao Lilan replied without thinking:

"European knight armor is not fully enclosed. There are many ventilation holes and observation holes on the helmet alone."

"Since the blood of the deceased can be sprayed on the helmet in large quantities, there must be a lot of blood sprayed on his face through the holes in the helmet."

"And blood is not so easy to wash off."

"We only need to conduct a luminol occult blood test on all the suspects present, and the case will be solved!"

She recalled the knowledge that Lin Xinyi had explained when he solved the case at the tram station, and quickly gave the simplest and most direct direction for criminal investigation.

When Mao Lilan said this, the police officers in the forensic department all reacted with belatedness:

"That's right...just do the luminol occult blood test."

"Whoever can detect blood on his face is the murderer!"

Everyone suddenly realized that they seemed to have finally come out of some strange circle of thinking.

The case suddenly became clear.

The expression of the old curator Ochiai suddenly became very subtle.

Mr. Kubota, who was just regarded as the murderer, immediately expressed his support excitedly:

"That luminol test, do it for me!"

"I can guarantee that there is absolutely no blood on my body."

He seemed to have found some life-saving straw, so he couldn't wait to ask for a luminol test.

Judging from Kubota's happy reaction to the test, he really doesn't look like a murderer.

But at this moment...

A team of police officers who had just been dispatched to search Kubota's office returned to the scene with a blood-stained suit of armor in a large bag:

"Report! We found this armor in Kubota's safe!"

"What, what?!" Kubota's expression changed drastically.

The Megure police department had a flash in their eyes, and immediately pointed to Kubota and said:

"Sure enough, Kubota, you are the real murderer!"

"The armor is hidden in your cabinet, and your name is on the note."

"And you must have used some special method to deal with the blood on your body after the murder, so you are not afraid of taking the luminol test at all!"

"I..." Kubota choked hard, sweating coldly and unable to speak.

And the police officers of the First Search Division obviously believed in the ingenious reasoning of the Megure Police Department.

They looked at Kubota covetously, as if they were about to pounce on him and capture him in the next moment.

"Haha..." Mao Lilan on the side suddenly laughed.

The atmosphere at the scene suddenly changed from tense to awkward.

"Ahem...Sorry, I suddenly thought of something very funny."

Mao Lilan's cheeks were slightly red behind the mask, and she apologized very embarrassingly for her faux pas.

But... there's no way, it's too funny.

When she was a bystander in the past, she felt like she was watching gods fighting, and she felt that both the detective and the murderer were very powerful.

Over time, Mao Lilan also thought that an ordinary girl like her could not participate in such a profound intellectual game.

But now, after learning a little about scouting techniques...

The scheming, insidious and cunning murderer in the imagination suddenly turned into a monster illuminated by the Golden Bowl Buddha, showing his true colors in front of her.

It’s like a master fortune teller whose tricks have been exposed, not only does not appear to be unpredictable, but it is very funny:

After all... after killing someone, you still leave the armor where the police can find it?

This is too stupid, right?

"Since the armor worn by the murderer is still there, the case will be solved more easily."

"Wearing this heavy armor for strenuous exercise, the lining of the armor rubs against the human skin, leaving dander and hair easily."

"Moreover, there will definitely be the sweat and smell left by the murderer inside."

"so…"

Mao Lilan took off the blood-stained gloves, walked over to lead a big black and yellow dog:

"As long as Caesar is sent out, we will find the murderer immediately."

"Wow, woof!" Caesar showed his white fangs, and roared twice.

Among the crowd, the expression of the old curator Ochiai became more and more complicated.

And Mao Lilan recalled the content of the class during the day, and continued to raise her voice and said:

"Even if there is a lot of blood on the armor, it will not interfere much with the scent identification of police dogs."

"Because we can use the infection extraction method of the smell source—"

"Cut the clean degreasing gauze into squares and stack it in 3-5 layers, clamp it with tweezers, put it in the mouth of an odorless hot bottle, steam it and moisten it, and finally put it inside the armor and wipe it gently."

"The murderer's body odor will be extracted and transferred to a degreasing gauze, and the gauze will be taken away from the source of odor interference, and Caesar will conduct odor identification."

"In this way, we can accurately find the murderer."

After talking about this, Mao Lilan's eyes had faintly lit up.

This unprecedented experience gave her an unprecedented sense of accomplishment.
