Deep Blue Apocalypse

Marine geologist Chen Mo and biologist Su Wanqing, a divorced scientific couple, were the first to detect crises in abnormal events in the global ocean. They joined forces with scientists from around the world to launch the "Deep Blue Protocol", went deep into the Challenger Abyss, and discovered non-artificial cities and the ancient "Gardener" system on the seabed. Facing the cruel test questions given by the system - 73 ecological and civilization indicators, humans must prove that they are worthy of survival within seven days.
