"Because I accidentally heard what Miss Kazuo said. She once quoted a famous saying, 'Only by obeying reason can we become adults.' She said this sentence was told to her by someone she liked. And you also said
'It is not enough to possess knowledge with wisdom, the important thing is how to make use of this knowledge'. No matter which of these two sentences are, they are famous sayings of the famous French mathematician Rene Descartes."
Conan explained.
"It is indeed what Descartes said. I do respect Descartes very much. So, you actually know this. You are such an amazing kid."
Feng sighed.
"So, who first suggested starting the 20-peanut game with Miss Dai?"
Conan asked rhetorically.
"It's...he said it."
Feng thought for a while and replied.
"Knew it."
Conan couldn't help but say this.
"What does it mean?"
Officer Megure asked blankly.
"Miss Kazuo, she is testing Mr. Mine!"
Conan explained.
"Test? Test what?"
Feng said in confusion.
"Mr. Feng, your feelings for Miss Kazuo."
Conan said something that didn't match his appearance.
"What?"
Feng said somewhat incomprehensibly.
"Miss Hedai is betting her life. She wants to know, between herself and Miss Kumi, Mr. Feng, who will you choose? Mr. Feng has dated Miss Hedai before, so he naturally knows that she takes antihypertensive medications.
Drug Facts.”
Conan continued speaking naturally.
"Well...I know..."
Feng said with a nervous expression.
"Miss Kazuyo must have believed that you would help her instead of helping Miss Kumi to win. Because the wine she drank was raw grapefruit, it was a matter of life for Miss Kazuyo who was taking antihypertensive drugs.
However, you did not choose to fight with Miss Dai, but whispered in Miss Kumi’s ear and gave her a trick, allowing her to win!"
Conan said sternly.
"If it were me, I would drink all the wine. No woman can tolerate being betrayed in front of her eyes!"
Miwako Sato couldn't help but said this, glaring at Feng.
"ah……"
Feng lowered his head as if he couldn't bear such a condemning look.
In response, Miwako Sato folded her hands in front of her body and couldn't help but regretted:
"But at least now, the case is clear. Miss Kazuo, is it worth it to commit a crime for such a man?"
"I have a gloomy personality. Even if I go to college, no one wants to make friends with me."
Ando Kazuyo lowered his head, exuding nameless sadness:
"It's always...it's always been me..."
Ando Kazuyo recalled the past, tears filled his eyes——
"When I thought I was going to be alone forever, the only person who took the initiative to talk to me was Feng... He suddenly said to me: 'Do you know Descartes?' This was the first time I met someone who talked to me with such a topic.
So I couldn't help but laugh. Then Feng said to me: 'Your smile is very cute.'"
Recalling the happy past, Kazuo's face turned red.
"Because I'm stupid, at the beginning, no matter how hard Feng tried to tell me about mathematics, I couldn't understand it. But in order to keep up with him, even a little bit, I studied hard."
Kazuyo looked straight at a certain point in the sky and recalled.
"Wadai..."
After hearing Kazuyo's unexpected confession, Feng was speechless for a moment.
"Although I am stupid, Feng told me that it doesn't matter. He said that mathematics is much simpler than interpersonal relationships. As long as you keep thinking hard, you will be able to find the answer one day. He said that he just wanted to avoid those dirty people.
Only through interpersonal relationships can we enter the world of mathematics.”
"The man I loved so much was stabbed for his love. This must be the motive for murder."
Takagi Wataru lowered his voice and asked.
"There's no way he would choose a woman prettier than me. I'm used to this kind of thing."
Kazuo lowered his head and said in a humble tone, but then his tone was a bit resentful:
"But then, I accidentally heard Jiumei talking on the phone with her real boyfriend in the bathroom!"
"What!"
Feng was completely speechless.
"Jiumei said this. Because Feng appeared on TV and was very popular, and sold hundreds of thousands of books, he must have saved a lot of money, so he has to use up all the money. The two of them can use Feng's money
Traveling to Europe, they might even have a grand wedding ceremony, the two of them talked lively... Also, Jiumei said that after spending all Feng's original savings, television appearance fees and book copyright fees,
Say goodbye to him."
Kazuyo angrily told the truth.
"This... what kind of woman is this!"
Feng held his head in his hands and roared in disbelief.
Sadly, Kazuyo said:
"So, I have been thinking that I must not let Feng hear these dirty things... I don't want Feng to taste the feeling of being betrayed and deceived. And Feng also said that he just doesn't want to see the ugly side of human nature.
, so I entered the world of mathematics..."
"So you chose to kill Miss Kumi."
Although Takagi Sheba was very touched, he still said firmly:
"Even though the initial plan failed and accidentally injured the innocent Mr. Akechi, you still killed Miss Kumi!"
"no!"
Hearing this, Kazuyo suddenly collapsed and said:
"I did poison No. 16's cup in order to kill Kumi. So I regret poisoning the innocent gentleman for not stopping him from drinking the poisoned wine. However, because the number of contestants changed, I poisoned him.
Later, but by that time I had no chance to poison again!"
"What!"
Hearing what Hedai said, everyone present was shocked——
"In other words, you only poison the cup No. 16!"
Officer Memu said in surprise.
"That's right."
Kazuo nodded and said, "So I don't know why Kumi died in the end! She obviously didn't drink the poisonous wine I poisoned!"
…
"Something's still wrong."
Lying on the hospital bed, Gao Yuan, who had been quiet for a while, suddenly frowned and murmured to himself.
In response to this, Xiao Ai, who was lying on the edge of the bed and was about to fall asleep, couldn't help but straighten up, frowned, and said helplessly:
"I told you, don't think about the case!"
Pouting, there was some dissatisfaction in his tone.
"Don't you think it's weird?"
Gao Yuan was already thinking:
"Before I cast a ring and come to the 16th, it is actually difficult to predict whether Dr. Agasa or Mr. Feng will win in the end. In other words, if the murderer wants to kill Miss Kumi accurately, then the murderer will poison her again
The chance was only after I chose to release the water and throw one ring. But after that, Dr. Ari directly threw three rings and came to the 19th, so Mr. Feng only came into contact with Miss Kumi, and Jinbei never left at all.
Mr. Guofeng's hand, how should the murderer poison it?"
