The globe is swallowed by seawater, and order collapses. Jiang Yu risks his life to save his girlfriend and brother, only to be pushed by the two of them into a shark school together. Opening his eyes again, he returns to the early arrival of the last days, and also binds a god-level fishing rod capable of angling all things. Others are trapped in tall buildings, killing each other for a mouthful of water, but he fishes out a space ring, a workbench, firearms, and deep-diving equipment, upgrading his broken wooden raft into an unsinkable survival ship. But deep-sea giant beasts awaken, and a mysterious green-haired woman concludes a life-and-death pact with him, while deep inside Xihuan Mountain hides the truth of the last days.
