Marcus Chen, an ordinary data analyst, boards the luxury expedition vessel MV Horizon for a dream cruise to Antarctica. When a deadly Andes hantavirus outbreak strikes mid-voyage—killing three passengers and trapping 140 souls aboard—Marcus awakens a mysterious Survival System embedded in his consciousness. With a game-like interface that detects infections, analyzes pathogens, and unlocks medical skills, he must race against time to uncover a bioterrorism conspiracy orchestrated by a rogue tech giant testing biological AI weapons. Beside him stands Dr. Elena Vasquez, a brilliant virologist who becomes his ally—and something more. Fast-paced, high-stakes, and packed with system upgrades, this is one cruise where survival is the ultimate luxury.
