Ch. 1801Jumping Incident
A corpse appeared on the flooded, dark thirtieth floor and chased four men into a stairwell where the stairs had vanished. Three fell to their deaths while fleeing, and the surviving Thin Security Guard was found unconscious on the rooftop and questioned by Uncle Hat.
- The Fat Security Guard and the others found a bloodied corpse embedded in the thirtieth-floor wall, but it crawled out and stood beside it.
- The Thin Security Guard led the group into a fire escape, where they discovered that the stairs downstairs had become a wall, so they ran toward the rooftop.
- The four men tried to climb down from the rooftop, but the Thin Security Guard fell onto the man below, who grabbed the Fat Security Guard, and all three plunged to their deaths.
- Uncle Hat investigated the thirtieth floor and found no water, damage, or corpse, then discovered the unconscious Thin Security Guard on the rooftop.
- Uncle Hat questioned the Thin Security Guard, whose account of a haunting made the Relevant Department suspect a possible vicious-ghost incident while keeping open the possibility of a staged murder.
