When the tsunami apocalypse strikes, Hu Lang suffers a terrible betrayal in his previous life at the hands of his girlfriend, Liu Rumeng, and his sworn brother. They steal his supplies and leave him to die in the depths of the sea. Reborn, he returns to the day he was buying a marital home, when Liu Rumeng insists on having her name added to the deed of their 30-million-yuan new house. Hu Lang tears up their marriage agreement on the spot, activates the Ten-Thousandfold Critical Strike System, and obtains an infinite storage space. With less than twenty-four hours before the catastrophe, he spends every last penny frantically stockpiling supplies, storing away water, food, medicine, and fuel. As the coming maritime apocalypse approaches, he is determined to protect his family and take revenge on his enemies.
