My Chess Pieces Can Evolve

Transmigrated to a world of universal job transfers, Li Yao awakened an A-level Summoner class – the infamous \"sewer profession.\" His gold-digging school beauty girlfriend immediately dumped him, publicly humiliating him and attempting to steal his family's invaluable cultivation resources. Everyone mocked him, thinking his future was ruined. But at his lowest, a hidden \"Hextech System\" awakened, transforming his weak summons into legendary \"Chess Pieces\" capable of limitless evolution and bearing powerful equipment. With his passive, the \"Chess Player cannot be attacked as long as his pieces live.\" Now, with an S-tier Void Mantis capable of one-shotting monsters and an unkillable advantage, Li Yao faces the world that mocked him. His ex-girlfriend thinks he's ruined, but how will she react when her 'trash' ex-boyfriend becomes the strongest professional the world has ever seen, starting with the dungeon tomorrow?
