Not a Loser，I'm the Supreme Sorcerer

Adrian, the legendary Thunder God, sealed his powers and lived in hiding for twenty years to protect his young daughter—reduced to a janitor at the academy. His wife was murdered. Her killers walked free. His daughter grew up bullied and broken. When she's pushed to the brink by the powerful, Adrian shatters the seal—and the sleeping Thunder God returns. Twenty years of silence, for one moment of reckoning.
