I'm in Detective Conan, and I start with the Grand Theft Auto system.

Lin Shen wandered around the streets and alleys of Tokyo for an entire afternoon, acting like a mobile arms dealer, handing out revolvers to anyone he met and leaving without hesitation.

He himself was quite dashing, riding his mountain bike at breakneck speed, leaving behind a trail of lit gunpowder fuses.

But he had no idea that his casual action would trigger a series of chain reactions in every corner of Tokyo, falling down like dominoes.

At the home of Katsuhiko Minagawa. (The Valentine's Day murder case.)

This afternoon, Katsuhiko Minagawa got together with some university classmates for a Valentine's Day bachelor party, drinking and having drinks.

Tanaka Naomichi sat on the sofa, clutching a can of beer in his hand, drinking it quickly and heavily, his mood extremely bad.

Because he watched helplessly as his crush, Kaoru Sekiya, blushed deeply and presented a carefully wrapped little box to Katsuhiko Minagawa: "Katsuhiko... this... is my special chocolate..."

Her voice was filled with anticipation and nervousness, and her eyes sparkled.

Katsuhiko Minagawa didn't even glance at the box, simply pushing it back with a condescending and impatient tone: "Don't give me things like this anymore, isn't it annoying?"

Guan Gu Xun's smile froze instantly, her eyes quickly filled with tears, and her hand holding the chocolate stopped in mid-air, unsure whether to pull it back or continue holding it.

Tanaka Naomichi watched this scene, his hand almost squashing the beer can.

His anger surged, and the more he looked at Minagawa Katsuhiko's face, the more he hated him.

He subconsciously touched his waist.

There's a revolver I picked up on the street when I came here today.

The cold, metallic touch made his mind explode in an instant!

Without saying a word, he suddenly drew the pistol, aimed it at Minagawa Katsuhiko, and pulled the trigger repeatedly.

Bang bang bang!

Several bullets struck Minagawa Katsuhiko, and he fell into a pool of blood before he could even utter a sound.

Sekiya Kaoru screamed in fright, and the chocolate box in her hand fell to the ground and broke in two.

Tanaka Naomichi gripped his gun, panting heavily. Looking at the corpse on the ground, he felt no fear, only an indescribable sense of exhilaration.

Near Mihana Hospital. (The monthly gift-threating incident)

Ogino Tomoya's father originally planned to send a gift to Dr. Ogawa Masayuki every month, so that he and his son would live in constant fear and anxiety, slowly tormenting them.

But today he encountered a motorcyclist on the street who, without saying a word, shoved a cold revolver into his hand and drove off.

Ogino's father looked down at the heavy, real weapon in his hand, remained silent for a long time, and then changed his mind.

He didn't want to wait any longer.

Sending gifts every month and slowly tormenting someone is too slow to work. It's much more effective to just shoot them directly.

He tucked his pistol away and waited at the entrance of Mika Hospital.

As Dr. Masayuki Ogawa walked out of the hospital with his son, Yuta Ogawa, Ogino's father strode out from behind the green belt, raised his pistol without a word, and repeatedly pulled the trigger at the two figures, one tall and one short.

Gunshots rang out in the square in front of the hospital, startling a flock of crows perched on a street lamp.

Mihana Art Museum (Art Museum Murder Case)

Director Ochiai had originally prepared a complex plan.

He disguised himself as a medieval knight in armor, then lured the owner, Mr. Manaka, to the collection room, and then used divine punishment on him, killing him!

He had prepared this plan for a long time, and there were too many details to operate it. The armor was also too heavy. If any link went wrong, it would be easy to fail.

But on his way to work today, someone unexpectedly handed him a revolver, which made his whole plan much simpler.

He invited the owner of Zhenzhong to a blind spot in the surveillance system at the back of the exhibition hall, and said with a smile, "There's something I'd like to discuss with you privately."

The owner of the shop followed him without any suspicion.

Then Director Ochiai didn't even bother to pretend anymore.

He pulled out his pistol and fired two shots at the boss's chest, swift and decisive.

The boss, Zhenzhong, stared wide-eyed, opened his mouth, but collapsed without saying a word.

Director Ochiai looked down at the body, and after confirming that it was no longer breathing, he calmly tucked the pistol into the inside pocket of his coat, straightened his collar, and turned to leave the exhibition hall.

He walked with such ease that it was as if nothing had happened.

In an apartment in Beika Town. (The "Tenkaichi" Night Festival Murder Case)

When Kenichi Sasai returned from the street this afternoon, he excitedly shared his strange encounter with his roommate, Satoshi Imatake: "Isn't it weird? On my way back today, I saw someone handing out handguns on the street, and they were real ones!"

"At first I thought it was a toy, but when I got it home, I realized it was real!"

Upon hearing this, Jin Zhuzhi immediately became interested and leaned closer, saying, "Really? Let me see."

Kenichi Sasai smiled smugly: "Sure! Of course, no problem."

He pulled out the revolver, then casually aimed it at Imatake Satoshi's head and pulled the trigger.

Bang, bang.

Two bullets pierced the head of Takeshi Imatake.

He didn't even have time to show any surprise before he collapsed.

Sasai Kenichi watched with a smug smile as Imatake Satoshi collapsed, feeling incredibly satisfied!

----------

The Tanaka family's place was also a mess. (The case of the missing corpse murder)

Tanaka Tomofumi fired several shots at his older brother, Tanaka Kazuyuki, leaving him covered in blood.

He fired the gun while cursing, his voice filled with years of pent-up resentment: "They eat my food, live in my house, and they just stay here every day! That's one thing!"

"You have the nerve to extort money from me every few days? Do you really think I'm your little brother? I'm your ATM, aren't I?!"

He cursed and fired a shot, the gunshots echoing through the narrow room, making the windows vibrate, until he emptied all the bullets in the magazine.

………………

The entire city of Tokyo descended into chaos on this Valentine's Day night.

Those murder plans, meticulously planned over months or even years, were all interrupted—no, simplified—by a revolver.

Those who were hesitant to take action suddenly lost control of their emotions and acted on the spot because they suddenly had a gun in their hands.

Those who had long wanted to kill someone but had never made up their minds finally "mustered up their courage" tonight.

There are also some people who are simply looking to take advantage of the chaos and get rid of people they don't like, then shift the blame to "that mysterious motorcyclist who's been shooting guns all over the streets."

In any case, all the messes eventually converged in one place: the Metropolitan Police Department.

Inspector Megure sat in his office, sweat beading on his forehead, his phone ringing incessantly, and a dozen newly printed case reports spread out on the table in front of him.

With each page he turned, his expression grew more unpleasant.

First came the Minagawa Katsuhiko shooting, then the Ogawa father and son shooting outside Beika Hospital, followed by the shooting death of the Manaka boss near the art museum, then the Sasai Kenichi indoor murder case, the Tanaka Tomofumi brother murder case…

That wasn't all; other jurisdictions also reported more than a dozen similar shootings. Almost every report had a similar note in the corner.

According to witnesses, the suspect was using what appeared to be a revolver.

Inspector Megure took off his hat, vigorously wiped the sweat from his forehead, and took a deep breath.

He could already foresee tomorrow morning's headlines.
