"What is it? I was really poisoned?" Xu Shengyi could not react in time and looked at Ye Ling blankly.
At this moment, Little Fifth was also in a confused state. He asked Ye Ling,""What happened?"
Beside him, Haihara Ai crossed her arms and explained expressionlessly,"" The potassium cyanide can undergo an oxidoreduction reaction with the rusted copper coins. After the copper dioxide is dissolved, the rust disappears, and the location of the reaction becomes particularly new.”
Everyone looked at the rusted ten-yuan copper coin on the table. There were indeed some places where it was unnaturally golden.
Xiao Lan looked at Xiao Ai in shock and asked,""How do you know all this…"
Xiao Ai raised her head and smiled childishly. She replied in the tone of a child,""Dr. Ali told me all this.”
The doctor was stunned at first, then he grabbed his bald head and laughed." Because Xiao Ai loves to study, I taught her a lot of chemistry knowledge.”
Everyone was speechless. Kogoro couldn't help but complain,""No matter how much she loves to study, she's still a primary school student. Why are you teaching her such terrifying knowledge?”
Hearing Uncle Mao Li's words, Xiao Lan, who was beside him, was not convinced. She put her hands on her hips and reprimanded,"Dad! Don't you always ask Conan to demonstrate some dangerous criminal methods?”
"Hmm? Is there such a thing?" Kogoro was dumbfounded. He had no impression of it at all.
Conan cursed inwardly. Of course, Uncle didn't know, because Uncle was sleeping soundly when he was demonstrating the technique. Thinking of this, he hurriedly changed the topic and shouted at Ye Ling like a child,""Wow! Brother Ye Ling, you're really amazing! There are so many poisons in the world. How do you know which one the murderer will use?”
"That's right. Ye Ling, how did you know?”Officer White Bird asked in confusion. If he hadn't known that the poison was potassium cyanide, he definitely wouldn't have suggested using rusty copper coins to test it, right?
Ye Ling's answer made everyone speechless." Of course I guessed.”He paused for a moment before adding," To control the poison to an imperceptible amount and to achieve rapid and effective results, only potassium cyanide is the most suitable.”
……
After the poisoning incident was confirmed, Xu Shengyi's boss broke out in a cold sweat and could no longer remain calm. If he had smoked that cigar, he would probably have become a corpse by now, right? He had long heard of the famous name of potassium cyanide, but he never dreamed that it would be used on him one day…
"Who…when did you poison him?”He hurriedly asked Ye Ling.
"You also smoked a cigar in the car and were not poisoned. It can be seen that the murderer waited for you to meet us before poisoning you.”Ye Ling glanced at everyone and said lightly,""Therefore, the murderer is among us.”
As soon as he said this, everyone looked at the people around them in panic.
The murderer was among them? Who was it?
For a moment, everyone was on high alert, as if they had become enemies in an instant.
" As for the method of the murderer's poisoning." Ye Ling added," It's too dangerous to poison him directly. It's not good to poison him in the cigar box either. So, the most likely way is to apply the poison on the items that Mr. Xu will touch with his hands."”
" Ah!" Gao Mu suddenly realized and exclaimed," I see!" He would first apply the poison on the items that Boss Xu would come into contact with. When Boss Xu's hands were stained with the poison, he would die from the poison if he smoked or ate.”
"Could it be that the poison was on the table and chairs?”Inspector White Bird asked. Because the door was automatic, there was no need to touch it, so it was impossible to poison the door.
"It can't be on the tables and chairs because everyone's seats are random. After a pause, Ye Ling added,""I speculate that the most likely place for the criminal to poison is on the control button of the cable car.”
Kogoro suddenly realized." I remember now! After we entered the cable car, it was indeed Boss Xu who pressed the start button!”
There were only two buttons on the cable car, so it was very convenient to poison them.
"But how do we ensure that the person who pressed the start button is Mr. Xu? If the person who arrived early entered the hotel first, wouldn't the victim be someone else?”Professor Ali was deeply puzzled.
"This is exactly what I wanted to ask." Ye Ling scanned the crowd and questioned," Why didn't you enter the hotel before you arrived at the shore?" According to what Mr. Asahi said when he got out of the car, he should have told you not to wait for him. Moreover, there were only two buttons on the cable car that everyone knew how to operate, but none of you went in first and insisted on waiting for Mr. Asahi to press the button. It was too strange.”
"I'm not sure. When I came here, I saw Mr. Sato and Mr. Ford waiting by the shore, so I waited with them.”The female model Nainai said.
Everyone turned to look at Shuhu and Ford. Shuhu hurriedly waved his hand and explained,""Don't look at me like that. I was the second to arrive. I wanted to go in early, but Ford said to wait for everyone to arrive before going in together.”
At this moment, everyone's eyes were focused on Ford. Could the criminal be Peter Ford…That's right, he must have arrived early and smeared poison on the button. Then, he stopped everyone from entering the hotel and waited until Mr. Xu arrived.
Ford instantly panicked. Xu Shengyi was furious and shouted,"Ford! You bastard! I lent you so much money when you were in trouble, and you actually want to kill me!”
"No, I can't! No, it wasn't me!" " I just thought it would be rude to go in before the guests even arrived," Ford explained helplessly." That's why I suggested that we wait for you. Moreover, applying poison on the button was just Detective Ye Ling's guess. It was not the truth!”
"You only need to check to find out.”Inspector White Bird said.
However, Ye Ling shook her head." No, we can't find out because Mr. Ford was the last one to leave the cable car.”
Inspector White Bird's body trembled when he heard that. He immediately understood.
Why did Ford leave the cable car later than everyone else? It must be to remove the poison on the button…
"If my guess is correct, he quickly cleaned and wiped the button with a bleacher, such as NaClO, after everyone left the cable car. Even if the police investigated, they wouldn't be able to find any trace of potassium cyanide.”Ye Ling looked at Ford and said," And the tools he used to clean up have probably been thrown into the vast sea."”
" This..." Everyone was stunned. This guy's plan was too thorough, right? If Ye Ling hadn't been overly cautious and guessed in advance that the criminal might have poisoned Xu Shengyi, Xu Shengyi would have been poisoned to death. Then, the police would never have been able to find the source of the poison.
Speaking of which, even if Xu Shengyi was not poisoned to death, the fact that Ford had poisoned the button could not be confirmed.
Ford secretly heaved a sigh of relief. Fortunately, he had eliminated the traces of the poison in advance. Otherwise, he would have been in trouble.
However, when he raised his head, he saw a smile on Ye Ling's face, which gave him a bad feeling.
