Tokyo: Rabbit Police and Her Evil Partner

Chapter 6 Guessing Chain
Netizens who often kill people in Japan know that there is a legal statute of limitations for criminal cases in Japan. It is calculated from the day of the crime, and after the statute of limitations has expired, no prosecution will be made.

"That's right." Fushimi Shika admitted frankly.

Yuan Yuzi's confidence increased, and she continued to explain her reasoning in a low voice:

"The reason for this speculation is that Instructor Sakurai did not destroy the anonymous letter, which proves that she is fearless."

"Following this line of thought, I can make a bold guess. Why is the murderer so fearless? Because she is sure that she will not be caught. Then why is she so sure that she will not be caught? Because the statute of limitations has passed, and she will not be prosecuted even if she is discovered. Moreover, Instructor Sakurai may lose her job at the police academy because of this, so she is worried!"

Fushimi nodded: "Basically, it's what I thought."

This is what Yuan Yuzi was waiting for. She pointed a pencil at Fushimi Kaka's nose, made a gesture of "there is only one truth", and said, "But these speculations are full of loopholes!"

"From the beginning, your guess was based on the premise that Instructor Sakurai was a murderer. At this point, you have already assumed that Instructor Sakurai had committed a criminal case."

"So, your subsequent "chain of guesses" is nonsense!"

"Why doesn't destroying the anonymous letter prove that she is fearless? Why is she fearless because the statute of limitations has expired? According to this logic, I can also guess that Instructor Sakurai is innocent and saved the anonymous letter for the purpose of evidence investigation!"

"Speculations built on speculation are like a building built on quicksand. The wind will blow and it will collapse in an instant!"

After saying this long string of words, Yuan Yuzi felt as if she had taken a big gulp of ice soda in the hottest days of summer, and felt so refreshed that the arches of her feet tensed up.

However, Fushimi Shika did not show the shock she expected. He just shrugged without even looking at her:
"Then just let it be like this."

Yuan Yuzi frowned, thinking that Fushimi Shika was being stubborn. She said unhappily, "Did I say anything wrong?"

"No."

"I was right, you're not worth that price!" After saying this, Yuan Yuzi felt that she had gone too far. But she didn't want to admit her mistake, so she crossed her arms, turned her face away and said, "100,000 yen is too high, I'll only offer 50,000 yen!"

When money is mentioned, Fushimi Shika's expression changes.

He sighed and said that the pain of paying for knowledge is that there are too few people who know the value of it.

He had heard so many arguments like "I can do it too" in his previous life that his ears were callused and he was almost suffering from PTSD.

"In that case, I'll teach you a lesson for free." Fushimi Shika put down his paintbrush.

"Hmm? Are you not convinced?"

Yuan Yuzi licked her lips. She loved this kind of debate the most. Since elementary school, she had a meticulous language and logic ability, and could often refute the other party speechless.

"Indeed, my guess is logically untenable, but do you have any evidence to refute my guess?" asked Fushimi Shika.

"No need for evidence, just logical deduction..."

"How does that help the case? You're just reasoning to refute me. After saying so much, do you have a direction for the investigation?" Fushimi Ka put his arms on his knees, crossed his hands, and leaned forward like a wolf hunting: "If this goes on, it will just be a pure game of intelligence, right?"

This was the first time in Yuan Yuzi's life that she choked up.

But Fushimi Shika was not going to let her go: "Since you are so confident in your reasoning ability, why don't we play a little reasoning game."

"what game?"

Yuan Yuzi was a little surprised and didn't know what he was up to.

"We will randomly pick a person and ask him to imagine a murder case in his mind. We will ask him questions at any time and he can only answer 'yes' or 'no'. The person who deduces the truth first wins." The game that Fushimi Shika was talking about is the "Turtle Soup" that is well-known in later generations.

This game originated from the "Mysterious Omnipresent" message board of the Japanese online forum 2ch. Not many people surf the Internet these days, but Yuan Yuzi actually knew the prototype. She said excitedly:
"Isn't this a 'lateral thinking puzzle'? It involves situational reasoning using 'yes' and 'no'. I didn't expect you've read Sloan's book... OK, I accept your challenge!"

"What's the point of just competing for victory or defeat? Why not add some spurts?" Fushimi Shika narrowed his eyes, "How about a 100,000 yen bet?"

"Huh? Want to gamble?" Yuan Yuzi immediately became alert.

"Why, are you scared?" Fushimi Shika raised his eyebrows.

"Gambling is illegal, and civil servants are prohibited from participating in gambling." Yuan Yuzi said seriously.

As expected of someone with a criminal index of only 1%...

Fushimi Shika had to change the way he put it: "If I win, you must pay me 100,000 yen as a hiring fee; if you win, I will pay you 100,000 yen as a coaching fee, how about that?"

"No bet." Yuan Yuzi refused firmly.

Fushimi Shika kept a record for her in his mind: "If you don't want to gamble, then don't gamble. Go find someone to come up with the puzzles, and we'll make it quick and easy."

"Eh? Should I go?" Yuan Yuzi pointed at her nose.

"if not?"

"Then forget it..." Yuan Yuzi is socially phobic.

"There's really nothing I can do about you." Fushimi Lu stood up, looked around, found a male student who had finished his portrait painting assignment, walked over and asked for help.

Gen Yuzi quietly poked her head out, and seeing Fushimi Shika pointing at her and negotiating with the other party, she quickly shrank back behind the drawing board.

After a moment, a reserved boy with a flat head sat over.

"Nice to meet you. My name is Shiraishi Hidenori. Thank you for your guidance..." He bowed rather stiffly.

Fushimi Shika sat back down, introduced the general rules, and then announced, "Okay, let's get started."

Upon hearing this, Yuan Yuzi became fully focused and quickly got into the state.

Xiu Ze thought for a while, then his eyes lit up and he revealed the answer to the riddle:
"A blind boy walked into a restaurant, ordered a bowl of turtle soup, drank it, and then suddenly shot himself. Why?"

As soon as he finished speaking, Yuan Yuzi raised her hand and said:

"How about changing it? I've seen this question in a book before - the answer is that the boy was once shipwrecked. With no food, his father used his own meat to make him a bowl of 'turtle soup', which allowed him to survive. Later, the boy drank real turtle soup in a restaurant and found that the taste was different. After discovering the truth, he couldn't bear it, so he shot himself."

"Wrong." Xiu Ze said.

"what?"

Yuan Yuzi thought, could it be that he came up with the answer himself? He innovated on the previous puzzles, which was quite creative...

In this way, no one knows the answer to the mystery, so it can be said to be an extremely fair reasoning duel!
