I, Chen Mo, an ordinary takeout delivery person, was involved in this doomsday carnival. Before I could react, the community square downstairs of my house turned into a random dungeon entrance, which was refreshed on time at six o'clock every morning, as if some unscrupulous game planner was issuing daily tasks to players. It is said that more than 70% of the people in the world died in the dungeon in the first week, but those who survived got something called a "dungeon key". This key does not recognize identity or background. It only recognizes one thing - your understanding of the rules.
