Xuanzang and his disciples encountered two demons, Golden Horn and Silver Horn, at the Lotus Cave. Silver Horn changed into a Taoist to deceive Xuanzang and moved three mountains to imprison the monkey and kidnapped Xuanzang. With the help of the immortals, the monkey managed to escape and procure the demons' treasures, the red gourd and the jade bottle. The monkey sucked Silver Horn into the gourd and had a fierce fight with Golden Horn. Finally, the monkey won and imprisoned the demon in the jade bottle. It turned out that the demons were the Taoist Master's servants. The Taoist Master came and took them back.
