Kang Jinhyeok, a longtime gaming streamer and content creator, is the only person in the world who has successfully completed the notoriously difficult game Tower of Trials. However, as the game gradually loses popularity, his streaming career begins to decline, making it harder for him to earn a living. After dedicating eleven years of his life to the game, Jinhyeok decides it’s finally time to quit and move on, preparing to say farewell to both the game and his small but loyal audience.

 

But on the very day he plans to leave everything behind, the Tower of Trials suddenly appears in the real world. Along with it comes a terrifying warning: humanity will be destroyed unless players manage to clear every floor of the tower within ninety days. As panic spreads across the world, Jinhyeok realizes that his years of experience have made him the one person best suited to survive this deadly challenge. Armed with unmatched knowledge of the game’s mechanics, hidden secrets, and strategies, he sets out to conquer the tower and prove exactly what a true hardcore gamer is capable of.
