My Raft Became an Apocalypse Fortress

As apocalyptic floods engulf the world, Jack is betrayed by his ex-girlfriend Selena and the Howard family and left to die at sea. He unexpectedly activates the Infinite Evolution System, starting with a wooden raft and steadily upgrading his shelter and weapons. Along the way, he rescues his daughter Angela and a doctor named Elizabeth, scavenges resources, hunts sea monsters, and tears down the Howards’ empire. Growing stronger through the Deep Freeze, he finally builds the ultimate sea fortress and gets his revenge. But just as he takes control of this ruined world, the Second Civilization arrives from outer space, unleashing a whole new crisis.
