A meteorite from outer space triggers global tsunamis and red-fog mutations, turning the ocean into a hellish death trap. Lin Yuan, a survivor betrayed by his girlfriend and abandoned by his so-called best brother, awakens an SS-rank genetic ability called "Mechanical Overlord" in the face of despair, allowing him to dismantle anything and upgrade his vehicles. Starting with a broken wooden raft, he hunts sea beasts, wipes out pirates, and dismantles sunken ships to upgrade his vessel into a missile destroyer. With overwhelming modern firepower, he crushes mutated monsters and heretics. At the ruins of Atlantis, he uncovers the truth behind an ancient god's seal, hidden for ten thousand years. Ultimately rising from the depths, he leads the survivors through the waves toward a highland sanctuary.
