"Mr. Wise, may I ask you what is the matter?"

Coming to the courtyard, Sekiya asked, but her eyes were still focused on Katsuhiko Minagawa and Watanabe Yoshimi, who were talking.

"Sorry, but I'm actually a detective. I came to you to ask about Mr. Katsuhiko Minagawa. ”

Gao Yuan simply didn't hide his identity at this time, and said straight to the point, after all, if you want to know about Katsuhiko Minagawa , you have to fall on this Guan Guxiang who is Katsuhiko Minagawa is a childhood sweetheart.

"Detective?"

Somewhat surprised, Guan Guxiang exclaimed.

"That's right, I'm here to investigate something about Katsuhiko Minagawa."

Takato said, "I heard that Mr. Minagawa seems to have encountered something bad at school recently."

"Well...... It's ......"

A little squirming, Sekiya Xiang thought and confirmed, "Not long ago, I did hear that Katsuhiko had a few accidents at school and was almost injured......"

Saying that, Guan Guxiang was a little surprised and said:

"Mr. Detective, isn't it possible that those are not accidents?"

"I'm not sure if it's an accident, but since I'm a detective, it's my accusation to investigate the truth."

Gao Yuan said, "I heard that you have known Mr. Minagawa since childhood, so I want to ask you, do you think Mr. Minagawa has any enemies?" After all, looking at his character, it should be quite easy to get unhappy with others. ”

"Mr. Detective, Katsuhiko is not such a person!"

Hearing Gao Yuan say this, Guan Guxiang instinctively retorted, "If it hadn't happened like that back then, Katsuhiko wouldn't have been so self-defeating......

"Does that mean his parents?"

Thinking back to the plot of the original work, Gao Yuan asked tentatively.

"Yes."

Guan Guxiang was not surprised that the detective could find out these things, so he replied directly.

"But it's been years, isn't it?"

Gao Yuan wondered.

"Not really...... Although he was a little self-defeating before, he didn't do it like this...... It was only after he went to college that he ......"

"In other words, if Mr. Minagawa is prone to enmity, the most likely thing is that he is still in college, right?"

Seeing that Guan Guxiang said something a little twisted, Gao Yuan went straight.

"Perhaps."

Guan Guxiang also said with great certainty, "But, even if his personality may not be very good now, he will not have a grudge against others to do that kind of mischievous thing!" ”

In this regard, looking at the other party's emotions, Gao Yuan knew that he couldn't continue to ask along this line anymore, so he changed the topic:

"So, what about Mr. Minagawa's adoptive mother, his aunt?"

After all, it is the murderer in the original work, and Gao Yuan still has to confirm it.

"As far as I know, Katsuyan's aunt has always treated him very well...... Why does Mr. Detective ask that? ”

Sekiya Xiang wondered, But at this moment, Watanabe's beautiful exclamation came!

……

Hearing the screams, Gray Plains followed the sound, and immediately saw a man lying on the ground, struggling in pain, and a beautiful woman beside him was panicking and didn't know what to do.

"No one is allowed to come closer, stay where you are!"

At this time, Gao Yuan ran to the fallen man from the other side to the fallen man, and habitually shouted into the living room:

"Maori classmates, call the police immediately!"

Seeing this, Gray Yuan Wai let Bumi stay in place, and he couldn't help but run up, came to Gao Yuan's side, squatted down, and checked the condition of the man who fell to the ground-

"Little sorrow! How are you here! ”

Seeing the sudden appearance of Gray Plains, Gao Yuan was a little overwhelmed for a while.

"Mr. Wise, what happened?"

Gu Yin

When Moriran, Conan, and Toshihide Wakamatsu came to the courtyard, Conan asked first, followed by Katsuhiko's mother.

"Conan! Keep the living room live and no one can touch it until the police arrive! ”

Although Gao Yuan was a little surprised by the gray plain mourning that appeared here, he still calmly maintained the scene - although this time it was different from the original plot, it was best to keep the scene to facilitate the police's next investigation.

"Good!"

Hearing this, Conan immediately turned around and ran back to the living room, and Mao Lilan immediately took out his mobile phone and started calling the police.

"Hey! Who are you? Why should I listen to you! ”

Wakamatsu Toshihide said with some disgust at Takato.

"I'm a detective!"

At this point, Takato can only reveal his identity - damn, what the hell is going on, why is Katsuhiko Minagawa still dead! What the hell went wrong there!

Looking at it, Katsuhiko Minagawa fell to the ground, holding the dismantled one in his right hand, which was given by Watanabe Yoshimi, half-eaten chocolate, and in his left hand, holding a cigarette with the filter torn off, and Katsuhiko's mother was not the first to come to the fallen Katsuhiko Minagawa to the ground.

In the original work, there were two people who wanted to kill Katsuhiko Minagawa. One is Katsuhiko's mother, who poisoned the coffee, but this possibility was basically ruled out after Gao Yuan's temptation; The other one was the one called Nakamichi, who poisoned the filter of his cigarette, but now—

Looking at this scene, neither of these original techniques seems to hold.

"Katsuhiko! Katsuhiko! ”

Looking at Katsuhiko Minagawa who fell to the ground and struggled in pain, Katsuhiko's mother, Kantani Ka, and Watanabe Yoshimi all wanted to come forward to check.

"No! Lofty! Stop them! ”

Gray Yuan covered his mouth and nose at this time, and immediately retreated from Katsuhiko Minagawa and shouted towards Gao Yuan.

Hearing this, Takato could only step forward and stop them with his body, so that they could not get close to Katsuhiko Minagawa.

"Mr. Wise! Why! Kayan is still in pain! ”

Watanabe asked a little broken.

"It's potassium cyanate!"

Gray Yuan Ai walked up to Gao Yuan and explained:

"Once potassium cyanate enters the mouth, it neutralizes with stomach acid and causes chemical changes, producing a highly toxic substance called hydrogen cyanide. If you get close enough to inhale this gas, you will be poisoned and killed instantly! ”

"What!"

Most of the people present were medical students, and when they heard what Gray Hara said, they naturally knew what was going on, and they couldn't help but widen their eyes, and the eyes of Watanabe Yoshimi and Sekiya couldn't help but lose color......

……

Soon, Officer Twilight arrives at the scene with his officers, but Katsuhiko Minagawa has already taken his last breath.

The scene is very intact, there is a high distance in the courtyard, and Conan in the living room.

After learning that Katsuhiko Minagawa died of potassium cyanate poisoning, the police quickly tested the chocolate and cigarettes that Katsuhiko Minagawa ate, but no toxic ingredients were found.

The rest was coffee, cakes, and other foods that everyone had eaten, and the portion that Katsuhiko Minagawa ate was also checked, but none of them were found to be poisonous.

Faced with such a situation, Officer Twilight was a little helpless, looked at Gao Yuan who appeared at the scene, and couldn't help but say:

"Wise brother, you were on the scene the whole time, didn't you find anything?"

In this regard, Gao Yuan is also very helpless, this is completely different from the original plot!

In the cigarette case that Namichi gave to Katsuhiko Minagawa , all the cigarettes were free of toxins; And in the coffee, whether it is in the coffee pot or in the cup, there is no sign of poisoning; Katsuhiko Minagawa was examined all over his body, but he was not found to have any toxins on him.

Now, in addition to knowing that Katsuhiko Minagawa is an oral poison, how Katsuhiko Minagawa was poisoned, there is no clue at all!

Could it be that the capsule he took orally was poisoned?

was a little dazed, and Gao Yuan couldn't answer for a while, and Conan, who was also at the scene, felt the same way.

In this regard, Officer Twilight could only reluctantly follow the routine and questioned the personnel at the scene......

"Anyway, why are you here?"

Seeing that Officer Twilight didn't plan to ignore him for the time being, Gao Yuan couldn't help but squat down and asked Gray Yuan curiously.

"Don't get me wrong, I brought Yoshida-san to Edogawa."

Gray Yuan said lightly, looking to the side, standing silently beside Conan Ayumi Yoshida......
