After recovering from illness, Liang Chen unexpectedly gains the inheritance of the World Tree, enabling him to restore stamina with divine berries and communicate with natural spirits. Starting from the bottom of the county town, he enters the Yan's Martial Arts Hall to practice martial arts, continuously improving his strength through trials and forging bonds with loyal animal companions. As demonic infestations and missing persons incidents occur one after another, Liang Chen gradually discovers that someone is secretly colluding with demons. To protect his neighbors and rescue trapped children, he and his companions venture deep into perilous realms to investigate the truth. Upon returning from saving people, the villagers regard him as a protector, and the World Tree thus opens up a new direction for cultivation.
