Trash Contract Beast? My White Fox Has Demon Blood

Mocked at the contract ceremony for summoning only an F-rank white fox, Finn Carter faces public humiliation and the threat of becoming a slave. At his lowest, the Divine Evolution System awakens, exposing the fox's hidden demon bloodline and triggering a sudden celestial phenomenon that turns ridicule into suspicion. Given a single probationary chance, Finn is sent to a harsh mining camp. Every task the system sets has clear stakes: if he completes them, the white fox will evolve and Finn will reclaim the power he lost; failure means slipping further into bondage. Tension tightens as Finn battles the camp's cruelty, racing the system's clock to prove the fox's true strength and save himself.
