Conan: I've been linked to the tech tree system.

As soon as Kogoro Mouri entered, he noticed something was off. He looked down at the piano with a puzzled expression. "The edges of this piano look like they've been torn or pulled by something?"

“I think this must be a scratch from an eagle, right? I suppose Hakuba-kun has already seen it here before,” Mogi Harufumi replied, resting his chin on his hand.

Conan looked around and noticed something was wrong.

"Hey, look, there seems to be something stuck on the keys of this piano."

Harufumi Mogi looked over and, sure enough, found some text written on rough cardboard between the piano keys.

The old-fashioned way of recording events reminded them of that strange legend from forty years ago.

“So this is where the so-called treasure is located…” Mogi Harufumi looked at it, but didn’t find anything interesting, so he casually put it on the piano.

"Huh? That's strange, why is this piano wet?"

Conan keeps saying "Ah-re-re" and "Oh-ga-shi-do," always playing dumb and acting cute.

“It seems that’s how it is…” Mogi Harufumi squatted down and found a can of fluorescent reaction liquid under the piano.

This is something that probably only a former coroner like Ikumi Gunta would carry around.

"These belong to that young lady... It seems she was in this room too."

"Hey, little mustache, why don't you go turn off the lights?" Harufumi Mogi said to the uncle.

"Huh? Oh..." Kogoro Mouri went over and turned off the light.

In the darkness, fluorescent blue lettering appeared on the side of the piano.

"There are still more details to the case from 40 years ago."

This is a blood letter left by an unknown person.

"In that case, Hakuba Saguru and Ms. Yata, who have been here before, must have seen this thing... but I don't know why they didn't mention it."

Kogoro Mouri and Harufumi Mogi stared at each other.

"Could it be that?!"

......

The sound of hurried footsteps rang out, and the three people downstairs rushed up the stairs.

White Horse, the blue suit jacket of the hidden warrior, was stained with blood on the front, and he was no longer the elegant British gentleman lying on the floor.

Harufumi Mogi rushed over and helped him up.

"He's beyond saving; someone shot him through the heart."

He said in a low voice.

"Damn it, someone's in the stairwell!" Kogoro Mori exclaimed angrily as he charged toward the stairs.

The old, dilapidated cast iron railings of the spiral staircase creaked and swayed as Kogoro Mouri pushed open the oak door to the top floor.

This is the place the organizer once said, where anyone who knows the location of the treasure can come and share its location with him.

Kogoro Mouri looked around.

Ikumi Gunda lay on her back in the center of the carpet, her dilated pupils reflecting the brown of the ceiling, her eyes still frozen in shock, as if she had died with her eyes wide open.

"Miss Gunda!" Kogoro Mori exclaimed in shock.

Harufumi Mogi followed him up and saw the same scene.

"The doorknob is specially designed so that a needle will emerge when it is turned from the inside." He carefully turned the doorknob.

"Anyone who enters the location of the treasure into the computer will die from poisoning the moment they touch the doorknob before leaving." He walked into the room and looked at the corpse of Gunda Ikumi.

"But where exactly is this murderer..." Kogoro Mouri wanted to ask more questions.

"Click," the sound of a bullet being chambered rang out.

"Stop pretending." Mogi Harufumi turned his head, drew a pistol from his waist and pointed it at Mouri Kogoro. "If she had set these traps, she wouldn't have fallen for them. Your daughter and that woman were drugged outside the bathroom again."

"If that gunshot was just a decoy, then the only ones capable of killing are you and me."

“So since I didn’t do it…” Mogi Harufumi’s eyes sharpened.

"boom"

The bullet spun as it flew toward Kogoro Mouri.

Is someone missing from Chapter 152?

The oak door on the top floor creaked in the draft, and moonlight cast dappled shadows on the two people's faces through the stained glass.

The gunshot shattered the silence, and the bullet struck Mori squarely in the chest, instantly staining a large area red with blood.

Kogoro Mouri was unable to react, except to clutch his chest and slowly collapse to the ground.

"Heh." Harufumi Mogi chuckled, pulled out a cigarette from his breast pocket, and lit it with a flair. "The sleeping detective... Don't blame me for suspecting you, it's all fate."

As he said this, he took a deep drag on his cigarette, enjoying the sensation of the air circulating in his lungs.

Almost instantly, Mogi suddenly clutched his throat, staggered to his knees, and made intermittent "uh" sounds.

Not long after, he lay on the ground and fell silent.

......

Senjō's withered fingers swept across the monitor screen, revealing eight images of "corpses" in various shapes and sizes.

She picked up the now-cold black tea and gently touched her forehead.

"So many detectives have been brought in, yet they still can't solve it...?" She felt a throbbing pain in her temples.

To deceive them, they faked their own death and killed the troublesome Ooga no Shuzen... What exactly were these detectives up to? Anyway, it's a bit too exaggerated that not a single one of them survived.

Did no one survive the cosplay?

Just as she was sighing helplessly, the screen in front of her suddenly flickered violently, and the image of Bai Ma searching for the "corpse" turned into static, followed by the shutdown of more surveillance cameras.

"How could this be? A video camera..."

The old woman's cloudy eyes suddenly contracted, and the chair instantly recoiled, scraping against the ground with a sharp, piercing sound.

The computer behind him, used to receive information, gradually displayed the following text: "I have cracked the code to the treasure. Please come to the restaurant to discuss it with me in person. —The Seventh Detective."

"Who is it?!"

......

The double doors were suddenly pushed open, and the crystal chandelier cast a long, thin shadow of Conan.

The boy was standing on tiptoe, fiddling with the gilded clock in the center of the restaurant; the grinding of the metal gears was particularly clear in the silence.

“Generally speaking, people who would plant a bomb in a car are either suicidal or just plain stupid.” Conan jumped off the table.

"But there are exceptions, because only an explosion can create the illusion that you have been blown up."

"You're right, aren't you, Detective Senkan?"

A cold light flashed across Conan's glasses.

......

In the following time, Conan used his best deductive reasoning skills to completely reconstruct Chima Fuyuki's motives and methods of committing the crime step by step.

"...Once the detectives discover the location of the treasure, you can silence everyone."

Conan walked to the window, turned his back to Chima Kazuyo, and looked at the scenery.

"Just like what that wealthy tycoon Karasuma Renya did, the last word written in blood behind the piano was actually the name of Senma Kyosuke. That was probably..."

“That’s my father’s name,” Senma Kazuyo finally chimed in. “My father used to be an archaeologist, a very wealthy man who was over a hundred years old. He discovered a clue to a considerable treasure left to him by his deceased mother, so he wanted scholars from all walks of life to find that treasure for him before he died.”

"The letter also clearly stated that Karasuma Renya committed the atrocity of killing the scholars one by one because his death was imminent and they had not yet found the treasure for him."

"When I finally noticed that letter, more than twenty years had passed."

Chima Kazuyo, with her hands behind her back, explained to Edogawa Conan.

"This villa has changed hands many times, but I started this whole project two years ago when I unintentionally talked about it with Oosugi."

"He tried hard to decipher the code, but failed. Moreover, he had taken out a large loan to buy the villa... In desperation, he came up with the idea of ​​framing Kaito Kid."

"Then why did you kill him?" Conan asked.

"Because he had already planned to kill everyone to silence them after the deed was done, including me."

"He had placed pistols in everyone's rooms beforehand, so he could use this as a pretense to avenge his comrades..."

"In order to stop this fool who is possessed by Karasuma Renya, I had no choice but to strike first. But the result was the same as 40 years ago. The code was not deciphered and the tragedy of death was repeated."

"No, you're wrong."

Conan jumped back onto the top of the fireplace, next to the fireplace that was about half his size.

Under Chima Kazuyo's astonished gaze, Conan turned the clock's hands: "Starting from zero, turn the hands 13 degrees to the left..."

"Kara"

After the last part was completed, the clock suddenly fell to the ground.

Conan dodged with lightning speed, and the clock fell to the ground, breaking the paint on its surface and revealing its golden interior.

"This is... a clock made of pure gold!" Conan exclaimed in realization. "Looks like this is the so-called treasure."

“My father actually lost his life because of such a gold nugget…” Chima Kazuyo walked over, her tone full of sighs, “It’s truly unexpected.”

"Alright, now you can tell me how to escape from here, right?" Conan asked him.

"I lied to you from the very beginning. I had already decided to end my life here, but after I told this to Daishang, he seemed to believe it."

"Well, I knew it would be like this, Sister Senma."

A familiar male voice suddenly came from behind me.

The halo of light from the crystal chandelier danced on Conan's glasses, and Chima Kazuyo's hunched body suddenly stiffened.

She turned her head, her somewhat cloudy pupils reflecting the detectives filing in—the “corpses” that should have been lying in various parts of the villa were now blocking the doorway.

“This is impossible…” The old woman’s hoarse voice echoed in the restaurant’s dome.

“Nothing is impossible,” Harufumi Mogi replied.
