In Conan, people have a brain option system.

Chapter 4 Unexpected
"That's right, Conan, you are awesome."

Yumi Miyamoto looked at Conan in front of her in surprise.

"In traffic accidents, it is not uncommon for car engines to be damaged, leading to carbon monoxide leaks in the car, so we always carry a carbon monoxide detector with us."

"When Miaozi and I discovered that the man in the passenger seat had passed out and the carbon monoxide concentration in the car was abnormally high, we immediately turned off the engine and carried the man out."

“It was indeed a very professional response.”

Conan frowned and nodded slightly.

He looked at the unconscious man lying on the ground, with a complicated look in his eyes.

At a time when the male passenger in the passenger seat was unconscious due to the high carbon monoxide concentration, his life would have been in danger if he had stayed in the car for one more second.

No matter what the reason is, Conan treats all criminals with the same disgust.

But he would never just stand by and watch someone die.

Even if the other party is the murderer who just committed murder.

"When we came here just now, the car was already turned off. This cheap K-Car does not have the function of automatic engine start-stop. I should have thought of this earlier."

After checking the situation inside the car, Masumi Sera came to Conan's side, looked down at Akikawa Sosuke lying on the ground, and spoke softly.

"Even if they found him earlier, so what? Officer Miyamoto and the others had already moved him to the open space nearby." Conan was puzzled.

"If that were the case, I wouldn't have directly questioned Officer Miyamoto."

There was a hint of loss in Sera Masumi's tone.

Originally, she wanted to have a good relationship with her second brother's fiancée, but she accidentally made an impolite remark questioning her professionalism.

Then, Sera Masumi changed the subject and continued:

"Come to think of it, the death of the victim this time is even more tragic than the victims of the serial murder cases in recent times."

"Of course, the serial murders are just disguised through exchange killings. In fact, the murderers have no hatred towards their victims, so they just want to end their lives as soon as possible, so naturally they won't do anything very cruel."

The so-called exchange killing is a method in which two people who each have a target they want to kill exchange targets in order to conceal their motives for the murder and create an alibi.

"Yes, I just observed the victim's wounds. Almost every wound can feel the murderer's overflowing hatred for the victim."

While speaking, Masumi Sera kept staring at Akikawa Sosuke who was lying on the ground.

Unlike Conan, who found it difficult to understand the murderer's motives even after hearing the murderer's confession, Sera Masumi was curious.

What on earth had happened that made the man in front of him feel such great hatred towards that woman?

As soon as Sera Masumi finished speaking, she heard the sound of sirens coming closer and closer.

Then Conan and the others saw,
Takagi Wataru, the patrol chief of the Metropolitan Police Department's First Investigation Division, arrived at the scene of the car accident with police officers from the Metropolitan Police Department's Forensic Division.

Takagi Shigeru acted very efficiently. After briefly understanding the situation with Miyamoto Yumi, he and the police officers from the Forensic Department began the on-site investigation and fingerprint identification work.

"Although the victim's death was tragic, the circumstances of the case are much simpler."

Looking at the busy police officers from the Forensic Science Division and the detectives from the Investigation Division 1, Masumi Sera couldn't help but speak.

The serial murders during this period had really exhausted her, so it was a blessing in disguise that she could come across a relatively simple case.

"Yes, as long as we can identify the second person's fingerprints on the murder weapon and compare them with the one in the co-pilot seat, we can basically conclude the case."

"As for the criminal's motive for murder, I find it hard to understand even if I hear it. I'll leave the rest to the police."

There was also a sense of relief in Conan's tone.

He did not feel regretful for not being able to help this time. Instead, he felt fortunate because the case was relatively simple.

At this time, the sound of the ambulance became clearer and clearer.

After the ambulance arrived at the scene of the accident, the medical staff, led by traffic police officer Miike Naoko, came to Akikawa Sousuke who was lying on the ground and prepared to lift Akikawa Sousuke onto a stretcher.

Everything seems to be going in an orderly manner.

however.

The relaxed atmosphere between the two detectives did not last long.

Because they clearly saw the increasingly confused expressions on the faces of the forensic police and Takagi Wataru.

A bad premonition began to arise in Conan and Sera Masumi's hearts.

The next moment, the hesitant voice from detective Takagi Wataru instantly made the uneasiness in the hearts of the two detectives become a reality -

"Officer Sato, no fingerprints other than the deceased were found on the dagger or the deceased's clothes."

"Eh?!"

"what?!"

Masumi Sera and Conan exclaimed at the same time, and then turned their heads to look at Akikawa Sosuke lying on the ground.
-
The two childish and slightly neutral exclamations finally relaxed the tense spirit of Akikawa Sosuke, who had fallen into a coma.

Akikawa Sosuke woke up about a few minutes ago.

But he didn't make any move, except that he wanted to pretend to be unconscious to eavesdrop on the conversation between the two and understand the progress of the case, or because Akikawa Sosuke couldn't move at all at the moment.

This situation of regaining consciousness but being unable to move the body is not unfamiliar to Akikawa Sosuke. This is one of the symptoms of carbon monoxide poisoning.

Locked-in syndrome.

The two detectives discovered that things were different from what they had originally expected.

So far, the development of things is still in line with what Akikawa Sorasuke expected before he fell into a coma.

"Although I don't know the exact time when the accident happened, based on the color of the deceased's blood that I just observed, I can tell that the accident happened no more than an hour ago."

"In such a short time, I was already showing signs of passing out. The carbon monoxide concentration in the car was at least 1600 ppm."

"Under this concentration, my life could be in danger within two hours. Simply opening the windows for ventilation is not enough to relieve the symptoms, so the police will definitely move me out of the car."

"As long as they move me before investigating the scene, the crime scene will inevitably be destroyed."

It was because he realized this that Akikawa Sosuke felt fortunate before he fell into a coma.

The lack of the original owner's memory is Akikawa Sousuke's biggest shortcoming at the moment, so it is difficult to deal with the aftermath thoroughly.

It is definitely the most reliable and safest way for the police to take the initiative to remove themselves from the crime scene.

After he was away from the crime scene, received treatment in the hospital, and recovered,
You will be able to have more physical strength and clearer thinking to think about and deal with what happens next.

"But speaking of it, the feeling of carbon monoxide poisoning is really uncomfortable."

"Although if the concentration is high enough, carbon monoxide can be fatal in just one or two hours."

“But the pain they endured during this period is immeasurable.”

Many people once thought that it would be quite easy to end their lives by carbon monoxide poisoning.

However, they don’t know that during carbon monoxide poisoning, they will have to endure the intense dizziness, palpitations and nausea that linger in their minds.

And even if you regret it halfway, it will be too late to change the situation, because after carbon monoxide damages the brain stem, the body is out of the control of the brain.

Even if they are lucky enough not to die in the end, their brain is likely to be severely damaged, leaving them with lifelong disability.

“I hope it doesn’t hurt my head.”

Akikawa Sosuke prayed silently in his heart.

He knew that he was not smart enough.
But now after traveling through time, my brain is one of the few weapons I can rely on.

"As long as we can survive this crisis, we should be able to live a peaceful life in the future."

Akikawa Sosuke was thinking in his heart as he was carried onto the ambulance by medical staff.

Since Akikawa Sosuke was a strong suspect in murder, in addition to the medical staff, he was accompanied by Chiba Kazunobu, the patrol chief of the Metropolitan Police Department's First Investigation Division.

Just as the medical staff sent from the Fire Department were about to close the door of the ambulance, a childish voice interrupted their actions.

"Hey! Wait a minute, wait a minute!!"

Conan shouted loudly and ran towards the ambulance.

"Hey, Conan-kun, what's wrong?"

Detective Chiba Kazunobu looked at Conan who was running over and asked in confusion.

"Officer Chiba, I want to go to the hospital with you!"

As Conan spoke, he saw Chiba Kazunobu's face showing some embarrassment, so he quickly added:
"Ms. Sera asked me to come along. She said there were some things she wanted me to help confirm!"

"Ms. Sera, please come up."

Chiba Kazunobu has great trust in detective Sera Masumi, who just helped the Metropolitan Police Department solve a serial murder case.

In addition, he also knew that the Metropolitan Police Department's forensic work at the crime scene was not going smoothly.

With the help of this observant little guy, perhaps there will be new discoveries.

So he opened the door and let Conan get in the car.

"How could the Metropolitan Police Department just let a child get on a vehicle carrying a suspected murderer?"

This scene left Akikawa Sosuke confused.

He had just heard the conversation between the kid who claimed to have solved a serial murder case and another person who was suspected to be a detective.

At that time, the child said in person that he would leave the rest of the matters to the police.

This means that although they are not from the Metropolitan Police Department, they can participate in the Metropolitan Police Department's reconnaissance work.

"In this case, either they have a good background or their personal abilities are extremely outstanding. Are they the latter?"

"It's strange enough that a child could be involved in the investigation of a murder case. It's just like that Death God Elementary School..."

Akikawa Sosuke couldn't help but complain in his heart, but his thoughts came to an abrupt end midway.

"Wait a minute, what did the detective named Chiba call the kid just now?"

Akikawa Sosuke's heart, which had just fallen back into his chest, rose again.
And when he saw clearly the face of the child who walked next to him, he suddenly felt a deafening thunder exploding in his mind.
