Feather of the Winged Demon

Second-level demon slayer Yan Zhengyu was targeted by the Winged Demon King because of his once-in-a-century bloodline spiritual power. His grandfather took him to the four top demon slayer families to learn how to slay demons. Due to an accident, most of the top slayers from the four major families died in battle, and the demon slayer world suffered heavy casualties. Yan Zhengyu embarks on a path to become a top slayer for revenge.
