Monkey comes up with a scheme of “fake marriage to escape the net” in order to fool the queen to return them their passports: only the master is to stay behind and marry, while the three disciples should leave to fetch the Buddhist scriptures. However, as the Tang Priest sees them off outside the city, he escapes as well. But in their haste, a she-devil suddenly kidnaps the Tang Priest. The brothers chase them to the Pipa Cave on Deadly Foe Mountain, where the she-devil jabs and injures Monkey and Pig with the sting of “horse-killer poison”.
