Introduction: A modern woman, Su Xiaowan, sacrificed her life in exchange for her younger brother's life, and her soul traveled to the Qijue Mountains of Journey to the West as a wild python spirit with no background. The original novel was destined to be disemboweled by Wukong. The original body maintained its human form by sucking human blood and abducted the villagers of Tuoluozhuang. When Tang Monk and his disciples went to the mountain to fight, Su Xiaowan released all the hostages in advance, and fabricated the story of the Peach Maid being demoted to the mortal world and Guanyin's enlightenment waiting for the sutra seeker to trick Wukong Bajie into dispelling their murderous intentions. She followed the master and disciple to meet Tang Monk, planning to use the opportunity of sutra retrieval to cleanse her demon body and get rid of the tragic death.
