Douluo Dalu 1 5 by Tang Jia San Shao

Reborn into a world where people cultivate spirit power by bonding with spirit beasts, a young prodigy carries knowledge from a past life and awakens an unusual Blue Silver Grass spirit, forcing him to conceal his true origins. Enrolling in an elite spirit school, he forges close bonds with a ragtag group of classmates who become his chosen family, and together they train, compete in brutal tournaments, and confront rival clans and hidden conspiracies that test their loyalty and resolve. As he hones his skills, uncovers secrets about his past, and faces ever-greater dangers, his journey becomes one of friendship, sacrifice, and the chase for strength and justice in a perilous, stratified martial world.
