In "The Legend of Mortal Cultivation," the author Wang Yu did not clearly describe the name of the main character Han Li's junior sister. He only mentioned a woman named Mu Peiling. She was once a disciple of Yellow Maple Valley, one of the Seven Great Sects in the State of Yue, and was Han Li's junior martial sister in name. In the early days of the novel, Mu Peiling was bullied by the other disciples of the sect because of her poor aptitude and weak family power. Han Li had coincidentally discovered her encounter and felt pity for her, so he often helped her. During their interactions, Mu Peiling had developed a favorable impression of Han Li. In order to repay her for saving his life and to make use of her connections in the sect, Han Li agreed to her confession and became her dao companion. However, Han Li wasn't serious about this relationship and only treated it as a method to use. Later, in order to pursue a higher cultivation realm, he chose to leave Yellow Maple Valley and wander the cultivation world. Before he left, he had given Mu Peiling his cultivation experience and some precious pills, hoping that she could use these resources to improve her cultivation. Although Mu Peiling knew that Han Li didn't have deep feelings for her, she still loved him deeply. She regarded the cultivation insights Han Li had left her as a treasure and worked hard to cultivate, hoping that she would be able to reunite with him one day. In the years after Han Li left, Mu Peiling had been cultivating in Yellow Maple Valley, and her cultivation had increased. She had also attempted to find Han Li's whereabouts many times, but she had never succeeded. Later, during a great calamity in the cultivation world of the State of Yue, Mu Peiling perished together with the enemy in order to protect the disciples of her sect. When Han Li heard of her death, he felt a trace of guilt. He realized that his feelings for Mu Peiling weren't deep, but she was sincere. All in all, Mu Peiling was an infatuated woman. She deeply loved Han Li, but in the end, because of the gap between the two of them and Han Li's indifference, she walked towards a tragic ending.
