Office worker Lin Ye accidentally enters the “Midnight Office Building” instance while working overtime at midnight, and is forced to embark on an adventure through an endless corridor. From obeying eerie rules and dodging eyeless NPCs in the office building, to uncovering the secret of the “Paper Figure Sacrifice” in a fog-shrouded ancient town, and then investigating the truth behind the “Hub” experiment at the Time Post Office, he gradually grows from a novice struggling to survive into an “instance breaker” who actively fights against fate.
