Falling into the eerie deep-sea viewing hotel dungeon, wealthy heiress Ji Fei has just stepped from the game world into reality. The plummeting deep-sea elevator, and the SSS-level big boss Shi Jinzhou disguised as a weakling, secretly protect her with their lives. Archenemy Zhang Cheng also appears here, harboring the malicious intent to recapture the substitute doll, and sets up a poison room-card trap, attempting to use the dungeon rules to eliminate Ji Fei. Inside the perilous hotel, death rules hang high, and players harbor ulterior motives. Ji Fei and Shi Jinzhou echo each other, cleverly returning the conspiracy to the opponent. The life-and-death breakthrough officially kicks off; beneath the deep sea, lies and slaughter have only just begun.
