The Adventures of Wu Kong vol.10 by Cun Ren

Having barely survived their most recent and difficult test, San Zang and his disciples must now pass through the treacherous Fire Cloud Kingdom, where an infant king with tremendous power aims to become the first monster to taste San Zang's flesh. Not long after the flame appears in the sky, San Zang hears a young child's cry for help. Sun Wu Kong is suspecious of the unfolding events, but even though the Stone Monkey has saved San Zang from monsters in disguise on numeruos prior occasions, the priest reprimands his disciple's suspecion and rescues the seemingly innocent child. Sun Wu Kong tries to eliminate the threat by throwing the monster off a cliff, but the child suddenly transforms into a cloud of flames and kidnaps San Zang. While struggling to save his master, Sun Wu Kong discovers his surprising relationship to the infant king. But while blood is thicker than water, it is no match for fire, and it will take more than Sun Wu Kong's bond with the young king to ensure that he and his three companions come out alive.
