Wukong was once instructed by Guanyin to convert to Buddhism and wait for the pilgrim day and night. Xuanzang passed by Wuxing Mountain, uncovered the letter from Tathagata, rescued Wukong, and named him Sun Xingzhe. The master and apprentice traveled together and stayed in a farmhouse at night. In a flash of white light, Tang Seng's white horse disappeared. Wukong found Yingchoujian and fought with the little white dragon, but never won. At night, three robbers came to rob the farmhouse. Wukong killed all the robbers. Tang Seng blamed him for killing, and Wukong left his master in anger.
