In the age of universal dungeons, anyone can be randomly swallowed by a dungeon gate. Those who make it out alive earn points, while dying inside means real death.
Li Fan is just a food delivery rider. His father died in a dungeon accident three years ago, and his mother is waiting for surgery. With no other choice, he scrapes together points by delivering orders and tackling low-level dungeons.
Then, in an F-rank dungeon, blue text suddenly appears before his eyes, invisible to everyone else.
Hidden rules, trap locations, routes to victory, reward coordinates: everything is crystal clear.
While others risk their lives to learn by trial and error, he clears dungeons by analyzing them.
F-rank, E-rank, D-rank, C-rank... The harder the dungeon, the more outrageous the rewards he earns.
But when Li Fan discovers traces his father left behind inside a dungeon, he realizes that behind the so-called dungeon rules lies a truth someone deliberately buried.
