I accidentally awakened the beast recognized by the entire academy as the “weakest SSS-rank in history” — a soft, squishy, bouncy Slime.While this harmless, derpy little creature was mocked by all of humanity as utterly useless, and everyone looked down on me with scorn, the long-silent system in my mind suddenly lit up with world-ending warnings. That was the moment my comeback began.

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.

Reborn into the apocalypse, I rise as an SSS Feralmancer. My ex leaves me for an S-rank genius, so I form a contract with a D-rank fox everyone laughs at. Hidden from all, she’s an SSS Novem Empress. With a dual contract, she evolves three levels in three days. When the beast tide descends and the city betrays me, she has already reached eight tails!
