In the crisis-ridden world of Hong Kong, Shao Xu was in a life-and-death crisis at the beginning. Fortunately, he was bound to the "Grandpa Yu-Gi-Oh!" Plug-in. The old man can predict danger, provide clues to solve crimes, and transform game cards into practical props. Shao Xu used the power of plug-ins to deal with gangs and the police force, solve serial cases, resolve fatal crises, and find a counterattack path with the blessing of "grandpa" in the unique territory of Hong Kong Comprehensive Games.
