In Conan, people have a brain option system.

Chapter 80 Confirmation
Most of the people attending tonight's dinner are well-known figures in the Japanese entertainment industry.

Most of the guests present knew Takao Ohkawa, a very famous plastic surgeon in the industry.

They looked at Ohkawa Takao sitting on the ground with a pale face.

He then looked at Masumi Sera, who seemed to be very skilled and had just helped with chest compressions, but now had his head lowered, exuding a strong aura of loss.

They also realized that the person lying on the ground should be dead.

Many of the guests around covered their mouths with their hands with grim faces.

The dinner was filled with a cheerful atmosphere, but the mood was destroyed in an instant.

"Ugh--"

Sera Masumi sighed and pulled himself together from the disappointment of not being able to save lives.

Then he slowly walked to the dead fat man and half squatted down.

She reached out and lifted the man's plump chin, and saw a very clear half-moon-shaped pinch mark on his neck.

It was obviously impossible for a man to be strangled to death in public.

In addition, when Sera Masumi heard the scream and rushed over, he also noticed that the man lying on the table was holding his neck tightly with both hands.

Then the pinch mark can only come from the man himself.

Masumi Sera turned her head and looked at the woman who was sitting at the same table with the dead man.

She was the only female among the guests at this table.

So Sera Masumi guessed that it was most likely her who made the scream.

"It was you who screamed just now, may I ask your name?"

Sera Masumi said while looking at the woman.

"Yes, my name is Soma Miho, who are you?"

Soma Miho gave her name, then looked at the "handsome guy" in front of her with confusion, not understanding why 'he' asked her name.

"My name is Masumi Sera, and I'm a detective."

Masumi Sera gave his name in Conan's classic tone.

When the people around heard Sera Masumi call himself a detective, their faces were moved.

When Ohkawa Takao, who was sitting on the ground, heard Sera Masumi call himself a detective, a look of surprise appeared on his sweaty face.

"Mr. Sera, you're asking me my name. Do you think I'm the murderer?"

Miho Soma is a well-known director in the industry, so naturally her mind works very quickly.

After she realized the purpose of Sera Masumi asking her name, the surprise on her face quickly turned into disgust.

"Are you sure that Mr. Kosaka was killed?"

"No, I'm just curious about your name, Ms. Soma. After all, you should be the first eyewitness who saw Mr. Kosaka faint."

Through Soma Miho's questions, Sera Masumi learned the deceased's surname and answered Soma Miho's confusion.

"Could you please describe what just happened, Ms. Soma?"

"We were just having a normal meal together, and then Mr. Kosaka suddenly looked a little strange, and then he grabbed his neck tightly with both hands."

"We were all a little stunned at first because of Mr. Kosaka's reaction. We thought he choked on his food."

"When I came to my senses, I found Mr. Kosaka collapsed on the table."

"Um"

After hearing Soma Miho's story, Sera Masumi

He confirmed that the other party's description was consistent with what he saw after Kousaka's death when he rushed over just now.

"Then may I ask, Ms. Soma, do you know whether Mr. Kosaka has a heart disease?"

"Huh? Heart disease?!" Soma Miho showed a surprised expression when she heard what Sera Masumi said, "I've never heard of it, and I've never seen Mr. Kousaka taking medicine."

While Soma Miho was describing the situation, Conan came to the dining table where the deceased Kosaka and Soma Miho and others were dining. He climbed onto the chair and began to observe the messy dining table.

After saying this, Soma Miho added:
"Although I know Mr. Kosaka, I'm not so familiar with him that I know exactly what disease he has."

"clear."

Sera Masumi nodded, then looked at Ohkawa Takao who was sitting on the ground.

After performing first aid just now, she had already asked for Ohkawa Takao's name.

"Just now, Mr. Taiga checked Mr. Kosaka's airway before giving him artificial respiration, right? I don't think he found any blockage in his airway, right?"

"No."

Ohkawa Takao shook his head slightly, but did not look at Sera Masumi.

Masumi Sera noticed that there were very obvious scratches on the back of Ohkawa Takao's left hand.

Blood had begun to seep out of the wound, and was clearly visible on Ohkawa Takao's delicate palm.

'Is it because I used too much force when doing chest compressions just now, causing the mechanical watch to scratch the back of my hand?'

"It seems that he used a lot of force when performing chest compressions on Kosaka. He must have really wanted to save Kosaka's life."

Masumi Sera thought about it in his heart and temporarily reduced the possibility that Takao Ohkawa was the murderer.

She put her fist to her upper lip and began to think.

"Mr. Kosaka had his hands around his neck when he died. There are six possible causes of death that match this behavior."

'One, breathing problems.'

'Two, heart attack.'

'Three, poisoning.'

'Fourth, nervous system disorders.'

'Five, neck injury.'

'Sixth, psychological factors.'

'At present, the last three situations can be directly ruled out.'

"Also, based on Ms. Soma's description, we can rule out the possibility of a heart attack for now."

"Since Mr. Kosaka's airway is not blocked, it means that it is not a case of "foreign body choking" caused by something like food stuck in the throat."

'Then the only possibilities left are suffocation and poisoning caused by internal factors.'

'The former is most likely an accident, while the latter is most likely man-made.'

Masumi Sera had just returned to Japan and had basically not encountered any accidental deaths.

So she was more inclined to consider the worst case scenario, that is, Kousaka's death was not an accident.

Masumi Sera came to the dead Kosaka and opened his mouth.
Then he took out his cell phone, turned on the flashlight, and carefully observed the inside of Kousaka's mouth.

'There was no damage to the oral lining, tongue or throat.'

Sera Masumi turned to look at Conan and asked loudly:
"Kid, is there any trace of Kousaka vomit on the table?"

"No." Conan replied.

'In that case, it can't be a corrosive toxin.'

Masumi Sera continued to lean over and smelled the scent in Kousaka's mouth.

What greeted me was a strong smell of bad breath mixed with the taste of alcohol.

Sera Masumi frowned slightly, and after careful observation, she did not smell the familiar smell of poison in Kousaka's mouth.
