Xiaolan can also solve the case?!

Conan couldn't help but be a little surprised:

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

It's just that after a day of study, a girl who can only boxing can solve the case?

Lin Xinyi is so relieved to hand over the important matter of human life to Xiaolan?

Don't say that Conan is not at ease, Xiaolan herself is not at ease:

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

The pressure of investigating the case suddenly fell on her shoulders, and she was afraid that she would not be able to do it well.

"It's okay, you can sure."

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

Lin Xinyi insisted on letting Mao Lilan shoulder this responsibility and solve the case.

On the one hand, he wanted to give Maorilan the opportunity to actually exercise.

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

There is nothing difficult in solving the case, as long as you learn it, anyone can do it.

The current atmosphere of public opinion holds the detectives very high, which indirectly gives criminals an illusion:

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

And Lin Xinyi just wants to break the illusions of these criminals:

Detective? Even if I call an apprentice who has only been studying for one day, I can catch you!

The deterrent power that the police have lost as law enforcement agencies has to be slowly regained in this way.

If anyone wants to commit a crime in the future, they must first think about whether they dare to go to prison.

"Remember—"

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

"Miss Maoliland, think of what I said about Rocca's law of exchange."

Lin Xinyi finally encouraged and reminded.

Maoliland, on the other hand, thoughtfully recalled Rocca's law of exchange, a theory created by French forensic scientist and criminologist Edmond Rocca:

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

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

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

"I see..."

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

She turned around and asked the police officer who had just come over to report the contents of the surveillance with a serious face:

"When you watch the surveillance video, there should be blood on the murderer's body, right?"

"Of course!"

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

"When the sword pierces the neck, it's like digging through an oil well... The blood hissed out a large basin, and the murderer was sprayed in the face on the spot. ”

"It's like that wall, the murderer is like he just came out of a pool of blood, and his armor is full of blood."

Glancing at the almost blood-stained walls, the officer described the contents of the surveillance with palpitations.

"That'll do."

Without hesitation, Mauriran replied:

"The armor of European knights is not fully enclosed, and there are many ventilation holes and observation holes on the helmet alone."

"Since the deceased's blood 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 isn't so easy to wash away."

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

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

As soon as Mao Lilan said this, the officers of the forensic division all reacted in hindsight:

"Oh yes... Just do the luminol occult blood test. ”

"Whoever can find blood stains on his face is the murderer!"

Everyone suddenly realized, it seemed that they had finally come out of some strange circle of thinking.

The facts of the case suddenly became clear.

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

And Mr. Kuwata, who had just been regarded as the murderer, immediately expressed his support excitedly:

"What a luminol test, do it for me!"

"I can assure you that there is absolutely no blood on me."

It was as if he had found some lifesaver, and he couldn't wait to take the luminol test.

Judging from Kuwata's reaction of being happy and happy about the test, he really didn't look like a murderer.

But at this time...

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

"Report! We found this armor in Kuwata's safe! ”

"W-What?!" Wata's face changed drastically.

And the Twilight Police Department had a gleam in his eyes, and immediately pointed to Watada and said:

"Sure enough, you are the real murderer!"

"The armor is hidden in your cupboard, and the note has your name on it."

"And you must have used some special means to deal with the blood stains on your body after killing people, so you are not afraid to do the luminol test at all!"

"I—" Watada choked hard, and he was speechless in a cold sweat.

And the officers in the search section clearly believed the subtle reasoning of the Twilight Police Department.

They stared at Wata, as if they were about to pounce on him in the next moment.

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

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

"Ahem... Sorry, something funny came to mind. ”

Maolilan's cheeks flushed slightly behind the mask, and he was very embarrassed to apologize for his faux pas.

But... No way, it's so funny.

In the past, when she was a bystander, she was like watching a fairy fight, 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 this kind of advanced intellectual game.

But now, after learning a little bit about survey techniques...

The scheming, sinister and cunning murderer in her imagination suddenly turned into a monster illuminated by the golden bowl Buddha, revealing her true form in front of her.

It's like a fortune teller who has been debunked for tricks, not only does it not seem unfathomable, but it is very funny:

After all... After killing someone, you still leave your armor in a place where the police can find it?

Isn't that stupid?

"Since the armor worn by the murderer is still there, the case will be easier to solve."

"Wearing this heavy armor for strenuous exercise, the armor lining rubs against the human skin, and it is easy to leave dander and hair."

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

"So..."

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

"Just let Caesar out, and we'll find the killer in no time."

"Woohoo!" Caesar bared his white fangs and roared twice.

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

Mao Lilan, on the other hand, recalled the content of the day's class and continued to raise his voice:

"Even if there is a lot of blood on the armor, it will not interfere much with the smell recognition of the police dog."

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

"Cut the clean absorbent gauze into cubes and fold it into 3-5 layers, hold it with tweezers, put it in the mouthpiece of an odorless hot bottle and moisten it, and then put it inside the armor and wipe it gently."

"The murderer's body odor will be extracted and transferred to the defatted gauze, and the gauze will be taken away from the source of odor interference for Caesar to identify the smell."

"That way, we'll be able to find the killer accurately."

After saying this, Mao Lilan's eyes were already faintly shining.

This unprecedented experience gave her an unprecedented sense of accomplishment.

Gradually, she seemed to have experienced the so-called fun of reasoning that she had been completely incomprehensible:

"Plead guilty, Mr. Murderer!"

"It's only a matter of time before Caesar sniffs you out."

"We'll do a luminol occult blood test on you, and we'll look for dander and hair in your armor to compare with your DNA."

"In the face of science and justice, you have nowhere to run!"

With her naturally gentle voice, Mao Lilan uttered such heavy and shocking words.

Like the light shining brightly, there is nowhere to hide.

"Hahaha..."

There was a helpless laugh in the crowd.

"I still deliberately came up with this kind of murderous trick of framing and framing, but I didn't expect it to be cracked so easily by a little girl."

"Sure enough... The darkness of a sinner cannot be concealed from such pure and bright eyes. ”

Director Ochiai laughed at himself with such emotion and took the initiative to stand up.

"Is that you?" Mao Lilan was slightly surprised:

She didn't expect that the murderer would be this kind and amiable old man.

"That's right, it's me."

The old man Ochiai let out a long sigh and admitted calmly:

"You defeated me, Miss Righteous Knight."
