The Primordial Insect Immortal

On the Chaotic Continent, humanity, demons, and barbarians each occupy their own domain, forming the Three Realms. Yu Song, a poor young man from the remote western lands of the Human Realm, sees his ordinary, impoverished life turned upside down when a strange insect immortal named Huaxu burrows into his mind. He draws talismans that turn the mundane into miracles, repeatedly gets expelled from the schools he joins, and faces danger at every turn as he travels the world. Each brush with death helps Yu Song grow rapidly, and along the way he meets many heroes and finds the love of his life.
