An ordinary man named Eliot Voss awakens an SSS-tier Miracle Designation talent, starting with an Eternal Ark that can evolve infinitely. He collects treasure chests, crafts equipment, tames spirit pets, makes allies, confronts hostile forces, competes for regional sea treasures, gradually builds his own exclusive island, and dominates the entire endless ocean.
