After Lin Chen, the King of Soldiers, died in the line of duty, he traveled to the world of Detective Conan and was granted a divine pupil by the Lord of Time and Space, with the goal of eradicating the evil in the world and gaining the opportunity to return home.
In order to avenge his victim, Akamatsu Motoichi, he carefully planned and used a series of traps to dismantle the wealthy Tsunada and his criminal forces. He gradually guided Conan and the police to solve the case, and used various hands to liquidate the criminals.
Lin Chen hid in the dark, strategized and leaked nothing, and destroyed transnational trafficking criminal dens one after another. He secretly handed over the core clues to the criminals, wandered outside the rules, and started a secret game with the clever Conan that no one knew about and was crushed throughout.
