Yoruichi Toyama still remembers that the drugs Kameyama and the others smuggled were heroin.

The raw material for that stuff is poppy, and considering the era Conan lived in and the situation in Japan, it might be possible to secretly cultivate it in the countryside.

The net profit from heroin production is as high as % or more.

That's why drug manufacturers and traffickers are so fearless of death.

However, the planting, harvesting, and purification of poppies involve a series of processes. If there really is such a production line on Moonshadow Island, and it has gone unnoticed for more than ten years, then Japan is truly doomed.

Not only was one island, Gunkanjima, hiding gold, but there was also another island producing opium?

The Tokyo Metropolitan Police Department is a bunch of incompetent bastards!

Although the discrepancy isn't that big...

Yoruichi Toyama coughed helplessly, still preferring to believe that the island was not a drug manufacturing base.

Judging from the size of this hidden compartment on the piano, Kameyama and his team are probably just secondary distributors.

Even so, the profit from a single smuggling operation can reach tens of millions of yen.

On such a small island with a low cost of living, having a net worth of over 100 million is enough to be considered extremely wealthy.

So why would those people stop?

Evidence, we must find evidence.

Only by exposing Kuroiwa and others who are still engaged in drug trafficking as soon as possible and handing them over to the police can we stop Asagi's revenge.

As Yoruichi Toyama fell into deep thought, a soft, melodious piano piece reached his ears.

It's as if it's lingering, hesitating, pondering...

The question kept repeating in my mind...

The moonlight from the sea streamed through the window like flowing water.

Music that flows like water.

Beethoven's Piano Sonata "Moonlight Sonata", first movement.

Yoruichi Toyama was taken aback for a moment before realizing that it was Akemi sitting at the piano playing.

Her fingering was skillful, and her expression was focused, as if she were already immersed in the music.

So she can play the piano, and she plays it so well...

This was Yoruichi Toyama's first thought.

Therefore, he did not speak for a moment.

But Amuro Tooru, as if completely lacking in elegance, spoiled the mood by saying, "This piano certainly has received special attention from someone."

Upon hearing this, Mingmei stopped playing, looked up, and smiled.

"Did Mr. Amuro notice that too? A piano that hasn't been played for two years wouldn't still produce such accurate sounds."

"Therefore, someone should come and tune the sound regularly."

Yoruichi's eyebrows twitched, surprised by her keen insight.

At the same time, the person he was thinking of appeared at the door of the activity room.

"Who are you?" a tall, dark-skinned man asked warily. "Why are you playing the piano here, and what are you playing...?"

Suddenly, the piano in the activity room, which had been untouched for a long time, started playing music. Surprisingly, it was "Moonlight Sonata," a piece related to the "curse." Anyone who heard it would probably get chills.

Upon realizing this, Akemi quickly stood up and bowed in apology.

"Excuse me, we are..."

"Oh, so you're the detectives who came to the island today?" the man said, walking in with an air of nonchalance, showing no fear whatsoever.

"No wonder he came to see the Aso family's piano and even played that kind of piece."

He showed off his canvas backpack, a hint of pride in his expression.

"How is the piano I've tuned and maintained?"

"Those islanders are ridiculous, talking about curses and all that. Even if there were a curse, how could it be on a piano?"

"Music is the most sacred thing in the world."

Looking at the simple infatuation on this person's dark face, Yoruichi and the other two were speechless.

...

According to the visitor, his name is Murasawa Shuichi, and he is a graduate of the music academy.

From a very young age, Murasawa greatly admired the musician Keiji Aso, and therefore took great care of the piano he left behind.

This is the person who comes to the activity center from time to time to clean and tune the piano.

There's really no need to hide this kind of thing.

The only thing Yoruichi Toyama cared about was the hidden compartment under the piano.

As soon as he mentioned it, Murasawa nodded.

"I already noticed it, but there was nothing in there."

"I wonder if this is where Mr. Aso hid secret letters or something back then, haha!"

His expression didn't seem feigned.

However, this is a point that differs from the original plot.

Yoruichi Toyama remembered that in the original story, this hidden compartment continued to serve its purpose of concealing and transferring drugs until Conan solved the case.

But this is just too abnormal.

For people like Kameyama and Kuroiwa, if they are the buyer and seller in a drug deal, it would naturally be safest to conduct the transaction at their own home.

Who would put drugs that they had gone through so much trouble to get into a piano that hadn't been moved in 12 years?

This illogical element from the original story no longer exists.

Could this be the influence of a time traveler on the world line?

Yoruichi Toyama scratched her head, somewhat regretting not bringing Taro along.

Even if we can't pinpoint Asagi's location, at least we can discuss the current plot.

While he was pondering these things, Amuro Tooru and Akemi had already finished introducing themselves to Murasawa Shuichi.

"So you're the son-in-law of Chief Kuroiwa!" Amuro Tooru exclaimed, half-jokingly.

Yoruichi Toyama could tell what he was planning just by looking at his expression.

Murasawa then solemnly corrected him, "Reiko and I are not married yet."

Reiko Kuroiwa is the only daughter of the village chief of Kuroiwa and the fiancée of the man in front of her, Murasawa.

Amuro Tooru waved his hand, indicating that those things were not important.
