Red Son tried to kill the Monkey King by controlling five carts that emitted in great amount of fire, but the latter cast a fire resistance spell and chased after Red Son, who went back into his cave after thinking he had defeated the Monkey King. Later on, as Red Son was fighting the Monkey King in a forest, he found Guanyin's empty lotus throne and then sat in it, imitating Guanyin's position. Suddenly the lotus throne transformed into swords, which pierced and wounded Red Son; as he attempted to take them out, the swords then transformed into halberds, which trapped him. In pain, Red Son pleaded for Guanyin to release him. In return, Red Son would have to also become Guanyin's permanent disciple.
