In Conan, people have a brain option system

Conan asked Mao Lilan for a handkerchief, and at the same time observed Akikawa Sousuke's neck wound again.

‘The angle of the wound is tilted upward, indicating that someone stabbed the neck with a dagger from top to bottom. ’

‘At the same time, the tear wound on the upper end of Akikawa Kousuke’s muscle tissue is relatively flat, while the lower end shows an obvious arc. ’

After Conan quickly confirmed this, he quickly pressed his handkerchief tightly around the wound on Akikawa Kyusuke's neck.

This is to try to control the bleeding as much as possible.

Although Conan judged from the bleeding degree of Akikawa Kosuke's wound that Akikawa Kosuke's carotid artery and jugular vein were not injured.

But this does not mean that Akikawa Kyusuke is out of danger.

In addition to possible shock caused by excessive blood loss.

Another hidden danger is that when non-professionals rely on tight pressure around the wound to control bleeding, they may compress the carotid artery and affect the blood supply of the injured person.

Fortunately, Conan had learned how to handle this situation in Hawaii, so he was able to avoid secondary damage caused by improper handling.

While controlling the bleeding for Kyousuke Akikawa, Conan turned to look at the dagger that fell to the ground.

I noticed that the false edge (upper edge) of the dagger is nearly (harmoniously) flush, while the main edge (lower edge), which is the main cutting edge, has an obvious arc.

At this moment, Conan suddenly felt his arm being grabbed hard.

He quickly turned around and saw Akikawa Kousuke's blood-stained right hand tightly grasping his left arm.

At the same time, Conan also saw the extremely panic expression in Akikawa Kousuke's trembling eyes.

"Am I going to die?"

Akikawa Kyousuke's lips trembled and he uttered a voice full of fear.

Conan was shocked again after hearing Akikawa Kyusuke's words.

Only then did he suddenly realize that he was too eager to analyze clues and ignored more important things——

Protect the injured.

In the process of emergency treatment, controlling the bleeding from the injured person's wound is not complete.

It is also particularly important to soothe the injured person's emotions and observe the injured person's breathing and consciousness.

If Akikawa Kongsuke is too panicked,

It is likely that the heart rate will increase due to sympathetic nervous stimulation and increased cardiac output.

At the same time, vasoconstriction caused by stress hormones and acute panic may cause blood pressure to rise.

Increased heart rate and blood pressure can further aggravate bleeding from wounds.

Secondly, people will also breathe faster when they are panicking.

This can lead to excessive release of carbon dioxide, lower carbon dioxide levels in the blood, and an increase in blood pH.

This is also called "respiratory alkalosis."

In addition, there are hidden dangers such as difficulty in effectively contracting and stopping bleeding due to damaged blood vessels due to muscle tension.

Therefore, ensuring Akikawa Kongsuke's emotional stability is actually quite important.

"No! Brother Akikawa! You'll be fine!"

"I have tried my best to control the bleeding from Brother Akikawa's wound. You will be fine!"

Conan said loudly to Akikawa Kyusuke.

"Brother Qiuchuan, don't move! Relax!"

"I've seen it on TV. If the injured person makes inappropriate movements, it may cause further tearing of the wound!"

"Don't worry, I promise brother Qiuchuan that you will be fine!"

Conan said,

He felt Akikawa Kyusuke's right hand that tightly grasped his left arm gradually relax and fall back to the right side of his body.

On the suit sleeve of Conan's left arm, there was a very clear bloody palm print.

——

The other side.

Kyouji Toda, who was being stared at coldly by Sera Masumi, quickly shouted out the truth of the matter:

"I didn't want to kill Akikawa Kyusuke!"

"That was because he wanted to commit suicide, so he stabbed himself with a dagger. I just wanted to stop him!"

"Then may I ask, why did Qiuchuan commit suicide?"

Sera Masumi's rhetorical question made Toda Kouji instantly choked up.

Why did Akikawa Kyusuke commit suicide?

It wasn't because of the truth he made up that Akikawa Kongsuke was exposed that he was the murderer, so he chose to commit suicide.

But how could it be said that Yu Shiliang really listened to this kind of thing?

Sera Masumi instantly sensed the clues because of Toda Kyouji's hesitation.

Her eyes became colder, and at the same time, the hand holding onto Kyouji Toda's collar began to become harder.

"You tricked someone into confessing again, didn't you, Officer Toda!"

Sera Masumi's words made Kyouji Toda feel a loud "bang" sound in his mind.

He didn't understand how Sera Masumi knew about the confession he had induced.

But before Toda Kyouji could deny it.

He once again heard the words that made his heart suddenly tighten——

"Inducing a confession, forcing a confession."

"Finally, he lured the prisoner to attack the police."

"These are all the things you have done, am I right, Officer Toda?"

"This was the case for Koichi Nishihara before, and it is the same for Takao Ohga this time. Their attacks on the police were all the work of Officer Toda, right?"

There was unconcealable rage in Sera Masaki's tone.

Toda Kyouji's face instantly turned pale after hearing Sera Masumi's words, and he didn't know what to answer at all.

‘How is it possible? ! How did she know all this? ’

‘Do I have a traitor among my people? ’

‘Or did Masumi Sera judge my method based on the news of their attack on the police? ’

This is a major secret related to the identity of Detective Toda Kyoji, and it must not be known to outsiders!

While Toda Kyoji was shocked by Masumi Sera’s sharpness,

Masumi Sera also fell into thought.

‘So Akikawa was forced to commit suicide by Toda? ’

‘Could it be that Akikawa, like Koichi Nishihara and Takao Ohkawa, also committed a crime? ’

Just when Masumi Sera was confused in her heart, she heard Conan’s voice:

“Sister Sera~ I saw that the wound on Brother Akikawa’s neck was tilted upwards.”

“At the same time, the upper end of the wound is flat, and the lower end is curved.”

After hearing Conan’s words, Masumi Sera made a judgment in her heart in an instant.

‘According to what the kid said about the shape of Akikawa’s wound, he was stabbed in the neck from top to bottom with a dagger held upright. ’

‘If that’s the case, then Akikawa definitely couldn’t have committed suicide! ’

‘Generally speaking, suicide involves stabbing the dagger into the neck from bottom to top, so the angle of the wound should be downward. ’

‘Also, according to what the kid said, the wound on Akikawa Sousuke’s neck is flat at the top and curved at the bottom, which means that the dagger that stabbed Akikawa Sousuke’s neck had the false blade (upper blade) on top and the main blade (lower blade) on the bottom. ’

‘And if Akikawa stabbed his neck from top to bottom, not from bottom to top, then the dagger should have been held in reverse grip, not in forward grip! ’

‘But if it’s held in reverse grip, the main blade of the dagger should be on top and the false blade on the bottom, which doesn’t match Akikawa Sousuke’s wound. ’

Sera Masumi denied the possibility of Akikawa Sousuke committing suicide by imagining two scenarios of Akikawa Sousuke’s suicide.

‘There is only one situation that can simultaneously meet the requirement that the wound is tilted upwards, and the dagger is stabbed into Akikawa Sousuke’s neck in a straight grip. ’

‘That is, it is the same as what I saw at the beginning——’

‘It is not that Akikawa Sousuke wants to commit suicide, but this Toda wants to kill Akikawa Sousuke! ’

Here, the straight grip and reverse grip refer to whether the dagger is stabbed into the body straight or reverse.

Straight stabbing: the false blade is on top, the main blade is on the bottom.

Reverse stabbing: the main blade is on top, the false blade is on the bottom
