"Because the poisonous cup happens to be number 16."

Hearing Officer Twilight's questioning, Conan couldn't help but explain.

"What does this have to do with the fact that the murderer is targeting Miss Kumi Ganjo?"

Officer Twilight asked, still puzzled.

"Because, if you follow the original rules of the game, this game would have had a winning rule."

Conan continued.

"The original rules?"

"The rule of victory?"

Wataru Takagi and Miwako Sato couldn't help but be interested in Conan's statement, so they asked out loud.

"Yes."

Conan nodded, and began to explain:

"Originally, this game that led to the killing of Kumi Ganjo should have only had two contestants. The number of rings that need to be shot is 1 to 3 rings. When all the players' scores are added up to each other, the winner is the one who finishes 20. It's the same game of stone picking that children often play. ”

"yes, I used to play a game of taking stones when I was a kid."

Officer Twilight said nostalgically, but then his expression changed slightly, and he looked at Conan a little speechlessly, and whispered:

"Aren't you a child yourself?"

"Whether it's a game of stones or a game of darts, as long as it's played by two people, according to the rules, there is a rule of win."

Conan naturally continued:

"And according to the rules of the game this time, as long as you can get the number 16, you will definitely win."

"Is that so?"

Wataru Takagi said with a surprised nod.

Conan immediately nodded:

"If it's two people playing, then after getting the number 16, there are only four left. One person can only choose 1 to 3 at a time, then the other person will never be able to reach the 20th. In other words, according to the original rules, as long as you poison the wine glass of the 16th, you will definitely be able to kill Miss Kumi. ”

"I see."

Officer Twilight said with a sudden realization.

"However, because of the special circumstances encountered today, which led to the end of the game with three people participating in the game, then this winning rule cannot be used. However, since the wine in each school girl's hand was poured before the start of the game, by the time the game became a three-person match, the murderer had no chance to replace the poisoned wine. ”

Conan explained, "That's why Mr. Wise, who got the number 16 in the race, was accidentally poisoned. ”

"That's right."

Miwako Sato understood what Conan meant, and couldn't help but praise:

"Kid, you're really not simple."

"Oh, no."

Being praised like this, Conan touched his head a little proudly and said.

"Wow! Conan is amazing! ”

Xiaolan on the side couldn't help but be surprised:

"Your reasoning skills are like ......"

Before the words were spoken, Xiaolan couldn't help but be stunned, and her mind flashed the scene when she encountered the case with Kudo Shinichi from before-

"Just ...... The new one! ”

Frowning slightly, Xiaolan suddenly had such an idea in her mind, and then thought of the day Shinichi disappeared, Conan appeared-

"But...... Don't...... It can't be......"

Although I wanted to comfort myself in my heart, I couldn't suppress such thoughts since they appeared-

"Is it difficult? Could this kid be ......?"

In other words, the murderer knew the final rules of the game in advance, and he also knew the winning rules of this game, so in order to kill Miss Kumi Kanjo, the murderer poisoned the wine on the 16th in advance. But because there was an accident and an accident in the game process, in order to ensure that Miss Kumi Ganjo could be killed, the murderer started another plan, but the 16th, who was already poisoned, had no chance to deal with it......"

After listening to Conan's words, Officer Twilight made an analysis.

"But if you think about it that way, the prisoner thinks very rationally, and the math should be good."

Miwako Sato analyzed.

"I see! In this way, it is really a method that only mathematicians can come up with to kill people! ”

After hearing all this, Wataru Takagi once again positioned the suspicion at the peak, and stared at him with a stern gaze-

"You...... Are you kidding me! Why did I have to poison the wine on the 16th? If I wanted to kill Kumi, I could have poisoned my own gold cup in the first place! ”

Feng retorted with some apprehension.

"So you didn't end up doing it, did you?"

Miwako Sato added, "Because the original poison was no longer able to be drunk by the deceased due to an accident, you can only poison your own gold cup in the end, right?" ”

"Didn't you say it?"

Feng roared, "What reason do I have to kill Kumi! If you have to say it, the Hibiki of the 16th is the motive! I've heard Kumi say that. And the cup in her hand wasn't tested to be poisonous! Why don't you doubt her! ”

"Is that so?"

Officer Twilight confirms to Miwako Sato.

In this regard, Miwako Sato looked at the results of the investigation in her hand, nodded and reported:

"Well, she has a motive for committing the crime."

"What is her motive?"

Officer Twilight asked.

"She lost to Kumi Kanjo in today's match and was second. After the game, several people saw the two of them clashing in the bathroom. ”

"Conflict?"

Officer Twilight asked meaningfully.

"Yes."

Miwako Sato confirmed firmly.

"I see."

After Officer Twilight finished speaking, he walked towards Hibiki Sakurai—

"You're Miss Hibiko Sakurai, aren't you?"

"Ah, I'm ......"

Although Sakurai Hibiko looked a little shaken, she nodded at Officer Twilight and replied.

"Several people testified that they saw you and the victim Kumi Kanjo in the bathroom."

Officer Twilight asked solemnly, but hearing this, Sakurai Hibiko became a little excited:

"I ...... Of course I quarreled with her! Because Kumi used dirty means to win the championship! ”

Hibiko Sakurai started the conversation without hesitation.

"Dirty means?"

Officer Twilight continued.

"Yes."

Hibiki Sakurai says:

"Before the start of the competition, Kumi went back and forth between the various sponsors, either eating with them or singing together, and pulled a lot of votes in advance."

"Oh? You can't forgive her for this behavior, so you poisoned her? ”

Officer Twilight asked sternly.

"How is that possible!"

Hibiko Sakurai hurriedly denied it, but Officer Twilight's questioning continued:

"But we've detected aconitine in your cup."

"What do you say? What is it? ”

Hibiki Sakurai asked blankly.

"It's useless to play stupid! Because you didn't become a champion, you resented Kumi Ganjo, and killed her in order to wash away this humiliation! ”

Takagi asked, squeezing through his voice.

"You've got a bad brain! Don't talk nonsense, uncle! ”

Hibiko Sakurai retorted strongly.

Hearing this, Takagi Shi couldn't help but be stunned for a moment, and soon said helplessly:

"Uncle? I'm not a few years old from you! ”

"Oh? Is that so? Who made you wear such a dirty suit, it looks like an uncle. If your so-called motive for killing is established, then the 18 people here should all want to kill Kumi in their hearts! ”

Hibiki Sakurai said proudly.

"Huh? Is that so? ”

Wataru Takagi looked at the other girls in shock, and all of them avoided his gaze and looked down at the floor.

"Look, everyone doesn't deny it, it's evidence."

Sakurai Hibiko said with a wry smile:

"Actually, before Kumi didn't participate in this competition, the competition would have been fair. When Kumi signed up, everyone began to use some dirty methods, just like her. After all, no one wants to watch themselves lose. ”

"I see...... However, the only thing that has been detected as poison remains is your cup. ”

Officer Twilight raised his eyebrows and glared at Hibiko Sakurai as he said.

"How do I know what's going on? Anyway, I don't know who handed me the glass...... At that time, because of the preparation of the game, the people on the stage were standing in chaos. ”

Hibiki Sakurai couldn't help but say:

"And, listening to what you just said, the murderer's method requires such a difficult calculation, is this something I can think of? It must have been Feng who did this on purpose to frame me! This guy is a very good dart player, but he is very famous! ”

"Sister Hibiki, is it something that everyone knows that Mr. Feng's darts play well?"

Just because after listening to Sakurai's words, the police were at a loss, Conan couldn't help but ask curiously.

However, Conan didn't notice that Xiaolan behind him was looking at him with solemn eyes......

……

On the other side, in the hospital ward, after Chiba and Shin asked Takato about something, they stopped disturbing Takato's rest and left for the time being.

Takato learned from Officer Chiba that poison residues had indeed been detected in the wine glass of No. 16.

In this regard, the little mourning on the side couldn't help but say:

"You're right. Luckily, you just took a sip so the poisoning wasn't deep, otherwise ......"

As he spoke, Xiao Ai's voice gradually became smaller, the word "otherwise" was almost silent, his expression began to be solemn, his eyes glanced at Gao Yuan, and then quickly turned his head, unable to say the next words.

In this regard, Gao Yuan couldn't help but sigh with emotion:

"yes...... I almost drank it all...... Almost! ”

As he spoke, Gao Yuan was suddenly stunned.
