Master Tripitaka and his three disciples were on their way to the Western Heaven to obtain the scriptures. As they passed a mountain, they saw a cave on the mountain with a grass shed and flower garden inside, which was very beautiful. Master Tripitaka ordered his disciples to go and explore, but Pigsy was captured by the White Bone Spirit inside the cave. Upon learning this, Sun Wukong and Sandy went to rescue him.

Sun Wukong angrily accused the White Bone Spirit of being too cruel to people, and began a fierce battle with her. Despite killing the White Bone Spirit several times, she continued to appear in different forms and challenge Sun Wukong. Finally, Sun Wukong relied on his wisdom to successfully defeat the White Bone Spirit. The White Bone Spirit turned into a pile of bones, which Sun Wukong burned to ashes, and he rescued Pigsy.
