A global flood forces 7 billion people into an ocean survival game. Calvin starts with nothing but a broken plank, but then awakens the hidden class: Legendary Mechanic. While others scramble and flee, he upgrades and rebuilds. Scrap wood, iron, crystal cores, broken weapons—everything can be reforged. From a lone drifter to the king of the sea, Calvin will turn that single plank into an aircraft carrier bound for the Ark Continent.
