Anime Crossover: An Assassin System Disguised as a Detective System

My transmigration went wrong! Jiang Hang was supposed to become an Assassin in Florence, but the System tossed him into the world of Detective Conan with a "2D patch." The System crashes on the spot for a week, then reboots and hurriedly renames itself the "Legendary Detective System." But when Jiang Hang opens the skill pool, he finds Assassin's Footwork, Breath Concealment, Hidden Blade Assassination, Spartan Kick, Mystic Eyes of Death Perception... What does any of this have to do with being a detective?

Feeling guilty, the System immediately offers him 100 million yen in hush money. "Being a detective pays better than being an Assassin." Jiang Hang shuts up at once. "Fine. From today on, I'm a detective who spreads positive energy!"

He opens an agency in Beika Town, and his first job is helping an elementary school student find a treasure map. After he rambles through some wild deductions, Conan suddenly has an epiphany and cracks the code. Three Italian gangsters tail the Detective Boys, hoping to steal their gold coins? Jiang Hang calls the police, Inspector Megure leads a team to arrest them, and the six-billion-yen Maple Leaf Gold Coins case is solved!

System reward: Combat Training and Hawkeye, worth 30 million yen. Conan starts questioning his life: How can some random detective solve cases better than I can?

In this life, I'll show the Grim Reaper elementary schooler what "Assassin-style case-solving" really means!
