Isn't it very scientific to use the Death Note to kill people?

Even if Light Yagami came to this world and went on a killing spree, the crime rate probably wouldn't go down—because most of the crimes here are premeditated rather than crimes of passion. The murderers might even deliberately lure detectives to their door, betting that the detectives and the police won't see through their carefully designed methods. Naturally, they would also bet that Kira wouldn't see through their methods.

Imagine Yagami Light wanting to kill the murderer but first having to be a detective, painstakingly investigating the truth—even Hayashi Yoshiki finds that unbearable.

"So you're Hattori Heiji."

Hakuba Saguru looked at Hattori Heiji and said, "I often hear my father talk about you. He says you're a very perceptive guy."

"Your dad? How would he know me?"

“My father is the Superintendent General of Police, which is very similar to your background of having a father who is the Chief of the Osaka Prefectural Police.”

"So, how many cases have you resolved?"

Tokitsu Junya asked a question.

Hakuba Saguru thought for a moment and said that although his main focus was in the UK, he had probably solved around 500 cases in Japan.

Where is Mr. Hayashi Yoshiki?

Koshimizu Nanatsuki looked at Hayashi Yoshiki with curiosity.

Feeling out of place under everyone's curious gazes, Lin Jiashu lowered her voice slightly: "There are probably only about twenty items..."

"what?"

His answer was somewhat surprising in front of several detectives with three or even four-digit numbers of clients.

Tokitsu Junya even showed a suspicious look.

Although he had heard of Yoshiki Hayashi's name while living in Hokkaido, he didn't know much about him: "He only had about twenty cases, yet he had such a big reputation?"

"Well, the publisher probably spent a lot of money on advertising for me in order to sell the book."

Hayashi Yoshiki was very frank.

But the people around them didn't think so.

"Although Yoshiki-san has been involved in fewer cases, he is definitely the most capable here."

Conan spoke up.

His words, spoken by a mere child to make up the numbers, were not enough to convince Tokitsu Junya. The problem was that Hakuba Saguru and Hattori Heiji were also nodding in agreement.

"That's right, Yoshiki-kun is indeed the most amazing detective I've ever met."

"...Since it's Detective Koshien, you're not going to participate too, are you?"

Hattori Heiji scratched his head.

What? Even these guys approve of it?

Tokizu Junya looked at Hayashi Yoshiki, who was just smiling, with surprise.

Chapter 392: Can You Understand? (White Horse)

After introductions, everyone began assigning rooms.

Just as Lin Jiashu put down his luggage, Hakuba Saguru came looking for him.

"Yoshiki-kun".

"Why did you come here?"

"I've heard about what happened with the special task force. The police leadership has decided to stop wasting their energy on finding the accidental killer. Why?"

"Because it's meaningless."

Hayashi Yoshiki's answer caused Hakuba Saguru's expression to change slightly.

He pressed for an answer, but Lin Jiashu didn't give a direct answer. Instead, he went to the window and opened it.

The wind on the island sometimes carries a faint salty smell.

Lin Jiashu observed the wooden house—it had probably been carefully renovated, as there were no signs of dampness or mold even though it was built on an island.

"The killer is not human."

"Not human?"

Hakuba Saguru looked astonished.

The unexpected culprit is related to artificial intelligence. After the answer was submitted, it was classified as top secret. Even though Hakuba Saguru is the son of the Superintendent General of Police, he did not receive any relevant information.

Seeing the unusually concerned expression on his face after he realized what was happening, Lin Jiashu seemed to pause for a moment.

After a while,

"The development of technology is truly incredible."

"From the steam age to the electrical age, and then to the modern era, humanity is now able to launch satellites to monitor a corner of the Earth from space."

"Can you understand, White Horse?"

"If there were something that could model everything—cities, traffic, pedestrians, the environment, and so on—and use mathematics and physics to perform countless simulations in a short time to achieve the goal of murder..."

What would you think?

Lin Jiashu, who was standing by the window, turned around and smiled.

Hakuba Saguru looked dazed.

Lin Jiashu has now presented the "answer" to him; he never imagined that the murderer would be like this.

But he had no reason to doubt it.

Although horrifying and hard to understand, this answer sounds much easier to comprehend than the idea that writing names in a notebook allows one to kill at will.

Do not……

That should be the answer.

That's the only possible answer.

Because if we're talking about whether such incredible things can be accomplished by human power alone, the answer is that technology is much more acceptable to people.

Hakuba Saguru had never expected this answer, so he stood there stunned.

He was lost in thought and didn't react when he heard Hattori Heiji and the others shouting outside the room, until Hayashi Yoshiki walked up to him and patted him on the shoulder: "Don't make a sound."

"……I know."

Hayashi Yoshiki and Hakuba Saguru walked out together.

Heiji Hattori and Conan stood in the corridor watching them.

"You two have a really good relationship."

The dark-skinned boy from Osaka spoke, but in his heart he was very curious about what the two of them had talked about. By now they knew that the task force that Lin Jiashu had joined was brought by Hakuba Saguru, so they must have been talking about related things.

Lin Jiashu didn't answer, but just smiled and asked, "How are your rooms?"

"It's alright. I checked and there's no mold or bugs."

"That's good. Let's go, wasn't Mr. Kagaya calling us downstairs just now?"

"correct."

So the group went down the stairs.

The housekeeper, Renzo Koya, had already prepared dinner. After Yoshiki and the others came downstairs, he led them to the dining room.

The wooden house we saw along the way was very old, with signs of repairs and maintenance everywhere.

"Excuse me, whose wooden house is this?"

"I don't know either. It seems to belong to some rich person, but they no longer plan to live there, so they rented it out cheaply."

Then Nanatsukoshi and Junya Tokitsu also arrived.

After being assigned a room, Koshimizu Nanatsuki changed her clothes, switching from a tomboyish, androgynous outfit to a school uniform sailor skirt suit. Her face, after taking off her sunglasses, looked elegant and cute.

"As a result, you all changed your school's system, which made me feel even more out of place."

Because it was a project about high school detectives, everyone changed into high school uniforms, even Hakuba Saguru, who said he was studying in England, changed into the uniform of Ekoda High School.

"Well, that's what happens when you're a special guest." Conan laughed, resting his hands behind his head.

"Mr. Lin, could you please sign your name for me in a moment?"

On the way to the restaurant, Koshimizu Nanatsuki smiled and took out a copy of Kindaichi from her pocket.

"of course."

Lin Jiashu readily accepted it.

...But in reality, this signature is meaningless to her now.

This whole affair was actually orchestrated by Nanatsuki Koshimizu—to avenge her friend.

A year ago, a locked-room murder occurred in a lavender villa in the Shikoku region: the young lady of the villa committed suicide by hanging herself in her room due to drug abuse and mental health issues.

A month later, a thief disguised himself as a cleaner and tampered with the window to make it easier to break into houses in the future. A high school detective noticed the problem with the window and, although he knew from the timeline that the problem was unrelated to the young lady's hanging, he kept telling the police that it was a murder case in order to gain fame and show off his reasoning skills.

Nanatsuko Koshimizu's friend was working as a maid at that villa at the time.

When the young lady locked herself in the door and hanged herself, only her friend was in the villa at the time. When the police and newspapers reported that it was a murder case, Koshimizu Nanatsuki's maid was suspected and questioned by her master's family and the media. Unable to bear it any longer, she chose to commit suicide.

"……alright."

Looking at the book in his hand, which showed many signs of being flipped through, Lin Jiashu quickly signed it on the title page.

"Thank you."

Koshimizu Nanatsuki took it and said with a smile, "Actually, I had thought about going to Beika Town to attend your autograph session before, but unfortunately I haven't been able to make it in time."

"Really? Well, my new book is due to be released soon. Would you be interested in coming over then, Ms. Koshimizu?"

"...Okay, that's fine."

Despite thinking that she might not have a future, Koshimizu Nanatsuki would never choose this moment to reveal her true colors.

Lin Jiashu put down his pen and looked out the window.

It's darker than usual tonight.

It's likely to rain.

Has anyone checked the weather forecast here today?

"Oh, the weather forecast said there might be thunderstorms tonight."

"It'll thunder..."

Speaking of which, Lin Jiashu is quite curious about what the scene looks like when someone is struck dead by lightning.

—Speaking of which, if Light Yagami had used lightning to kill criminals, his title of "god" might have been more fitting.

After all, even the weather can be manipulated; at that point, L might be at a loss.

Chapter 393: Hayashi Yoshiki's Regret (Part 2)

Dinner was prepared to be very lavish.

There was turkey roasted with bread, oysters and fish sourced from the seaside, pan-fried lamb chops, and creamy pasta.

As everyone excitedly prepared to eat after all the food was placed on the table, Conan suddenly realized that someone seemed to be missing.

Where is the director?

“That’s strange. When I went to his room just now, I didn’t get a response, so I thought he had already come over.”

Renzo Koya looked puzzled.

The high school detectives, who had solved hundreds of cases, immediately sensed something was wrong upon hearing this and all expressed their determination to find the other party quickly.

Renzo Koya dared not delay and quickly led the group to Hiroki Tsuchio's room.

However, no matter how much they knocked and called out, there was no response from inside. Heiji Hattori tried to turn the doorknob and found that it was stained with blood.

"There's blood on the doorknob?"

"Where's the spare key?"

"No, no... There's no key to this cabin. Everyone's room is the same, and they should all be lockable from the inside."
