Thousands of years ago, Immortal King Muyun was plotted for possessing the Zhuxian Diagram. After sleeping for ten thousand years, his remnant soul awakened in the body of the famous "waste Muyun" of Nanyun Empire in Tianyun Continent. When Mu Yun woke up, he was deliberately made difficult by his student Miao Xianyu. Mu Yun easily defused Miao Xianyu's trap and told more alchemy techniques by inference, which was appreciated by Mo Wen, the alchemy master outside the door. Incessantly. Back home, Mu Yun learned the news that he was going to get married to Qin Mengyao, a girl from the Qin family. Qin Mengyao was suffering from cold poison and could not live to be twenty years old. The marriage was only for the benefit of the Mu family and the Qin family. But under Mu Linchen's persuasion, Mu Yun agreed to the marriage on the condition of making alchemy. After refining the Bone Tempering Pill, Mu Yun's cultivation level 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 that Mu Yun should give Mu Yun a try, but Mu Yun accidentally awakened the Zhu Xian Tu in his body and learned that Qin Mengyao's body was not filled with cold poison, but the ice phoenix soul. Mu Yun cured Qin Mengyao, and the power of the Ice Phoenix Soul made Qin Mengyao's cultivation improve by leaps and bounds. After seeing Mu Yun's ability, Qin Mengyao was full of curiosity and interest in Mu Yun, so she became a tutor at Beiyun College and taught the same class as Mu Yun. Dongfang Yu, who failed to pursue Qin Mengyao, became jealous and hateful, and vowed to be incompatible with Mu Yun. Mu Yun used the Zhu Xian Tu to break through his cultivation and went to the Beiyun Mountains for training. Miao Xianyu insisted on going with him. On the way, Mu Yun hunted more than a dozen purple-haired wolves by himself, which shocked Miao Xianyu. The Four Evils of Liushan, who were assigned to assassinate him, followed him all the way. Taking advantage of Mu Yun's loss of power, they appeared one after another and prepared to attack Mu Yun.
