Ten thousand years ago, the Immortal King Mu Yun was plotted against for holding the Zhuxian Map. After his residual soul slept for ten thousand years, he awakened in the body of the famous "waste Mu Yun" in the Nanyun Empire of the Tianyun Continent. When Mu Yun first woke up, he was deliberately made difficult by his student Miao Xianyu. Mu Yun easily resolved Miao Xianyu's trap and said more alchemy skills by analogy, which made the alchemy master Mo Wen outside the door appreciate it. When he returned home, Mu Yun learned that he was going to marry Qin Mengyao, the young lady of the Qin family. Qin Mengyao had a cold poison in her body and could not live beyond the age of twenty. The marriage was only for the benefit of the Mu family and the Qin family. But under the persuasion of Mu Linchen, Mu Yun agreed to this marriage on the condition of alchemy. After refining the bone-quenching pill, Mu Yun's cultivation level was improved for the first time. Mo Wen often came to Mu Yun for advice, and Qin Shiyu always wanted to ask Mo Wen to treat his granddaughter Qin Mengyao. Mo Wen hinted to Mu Yun to give it a try. Mu Yun accidentally awakened the Zhu Xian Tu in his body and learned that Qin Mengyao's body was not cold poison, but the Ice Phoenix Spirit. Mu Yun cured Qin Mengyao, and the power of the Ice Phoenix Spirit made Qin Mengyao's cultivation progress by leaps and bounds. After seeing Mu Yun's ability, Qin Mengyao was full of curiosity and interest in Mu Yun, so he became a mentor at Beiyun College and taught the same class as Mu Yun. Dongfang Yu, who failed to pursue Qin Mengyao, was jealous and hateful, and vowed to be irreconcilable with Mu Yun. Mu Yun used the Zhu Xian Tu to break through his cultivation and went to Beiyun Mountains for training. Miao Xianyu insisted on going with him. On the way, Mu Yun hunted more than a dozen purple-haired hunting wolves by himself, which shocked Miao Xianyu. The four evil spirits of Liushan, who were assigned to assassinate the curtain, followed all the way. Taking advantage of Mu Yun's loss of strength, they showed up and prepared to attack Mu Yun.
