In the deep mountains and dry pine streams, there lived a Red Boy, the son of Bull Demon King and Princess Iron Fan. He was a powerful magician, naughty and competitive. He was waiting for Tang Monk and his disciples to pass by, hoping to honor his parents with Tang Monk's flesh. Red Boy used a trick of self-torture to gain Tang Monk's trust, and took the opportunity to abduct Tang Monk into the Fire Cloud Cave. Wukong and Bajie went to look for their master, but Red Boy led a group of little demons, spewing fire from their mouths, burning Wukong and Bajie and forcing them to flee.
