Following a local god’s suggestion, Monkey goes to find the Bull Demon King on Mount Thunder Piled. When the Bull Demon King is unwilling to lend him the fan, they start a fight. At this moment a person arrives, urging the Bull Demon King to attend a banquet. Thus the Bull Demon King requests the fight to stop so that he may attend the banquet in the Dragon Palace. Monkey secretly follows the Bull Demon King.
