Mu Yueluo is the most inconspicuous outer disciple of Kunlun Mountain, but because of stargazing on a moonlit night, he was spotted by the Immortal Lord Mo Chenyuan, who had been in seclusion for thousands of years, and became his only disciple. Mo Chenyuan was cold and cold, but he was very patient with Mu Yueluo, teaching her techniques and accompanying her to grow. However, as Mu Yueluo's life experience was revealed - she was the "Heart of the World" who could balance the power of immortals and demons, their peaceful master-disciple life was completely broken.
