Li Mingda and Li Cihang are the story of sisters who traveled through the prehistoric times. After Li Mingda traveled through time, he became the body of Kui Niu with his own cultivation in the Hunyuan Da Luo Jin Immortal Realm. He became the mount of the leader of Tongtian Cult. In the Battle of the Conferred Gods, he served as the eye of the Immortal Killing Formation. After the formation was broken, he fell temporarily; Li Cihang started in the human form Qi Refining Realm, became a disciple of Yuanshi Tianzun, and grew up to be Taoist Cihang, one of the twelve golden immortals in the Taiyi Golden Immortal Realm. After witnessing his sister's tragic situation, he switched to Western religion, and was later reincarnated as Princess Miaoshan to save his sister.
Then, Journey to the West began in the thirteenth year of Zhenguan. Li Mingda secretly prepared as "Princess Jinyang", and the Soul of the Zhuxian Sword was bound to her. "Little Sizi", "Princess Jinyang", "Princess Xincheng", "Origin of Kui Niu" and "The Soul of the Zhuxian Sword" all pointed to her. Being able to participate in the learning process was due to her special origin and realm; Li Cihang protected her with the maid "Green Calyx", and later replaced the title of "Princess Jinyang". The Buddhist scripture study lasted for 14 years until the twenty-seventh year of Zhenguan. Li Mingda used two identities in parallel. After the end, he returned the origin of Jin Chanzi (Jin Chanzi's tenth soul fragment) that he accidentally swallowed. His sister Li Cihang (Guanyin) returned to the South China Sea as the "Princess of Jinyang" and ended. Jin Chanzi was resurrected. After that, she lived as the "Xincheng Princess" until the third year of Longshuo (according to the historical death year). The core of learning the scriptures is to train the three disciples and help Li Mingda control the origin. Li Cihang has stabilized the Hunyuan Daluo Jinxian, but Li Mingda has manifested the Daluo Jinxian due to the instability of the origin. The two are far more powerful than the three disciples and Xiao Bailong. After accepting a disciple, Li Mingda's realm stabilized to the late stage of Daluo Jinxian, and during the story of White Bone Demon, he broke through to Hunyuan Daluo Jinxian.
