Raja Laut Kiamat

After a global flood forces humanity into an ocean survival game, Calvin starts with nothing but a broken raft. He soon unlocks the hidden class of Supreme Machinist, allowing him to upgrade and rebuild almost anything. While others struggle to survive, Calvin turns scrap into powerful equipment and sea monsters into valuable resources. As his raft grows into a mighty warship, he rises from castaway to ruler of the seas, setting his sights on the legendary Ark Continent.
