In the meantime, in a remote village, a gentle and righteous boy with the strength of a giant, witness the murder of his entire fellow villagers and the disappearance of his wife by the hand of an evil clan. Fortunately, the immortals of mount Zu intervene in time to save the boy's life and accept him as a new disciple.
