Nineteen years ago, the Qionghua faction used Wangshu and Xihe to bind the demon world with a double sword net, seizing spiritual power from it, triggering a war between the demons and demons, and both sides suffered heavy casualties. Yun Tianqing and Shuyu, disciples of the Qionghua faction, left Qionghua because of a disagreement over the concept of cultivating immortals of the Qionghua faction, and came to Qingluan Peak to give birth to a son, Yun Tianhe. Not long after, Suyu died. The young Yun Tianhe did not know the past of his parents, and his father Yun Tianqing also died of illness, leaving him alone to grow up in the mountains. Yun Tianhe (played by Chen Zheyuan) meets Han Lingsha (played by Ju Jingyi), a girl who broke into her parents' tomb, and goes down the mountain to find her parents' past together. Halfway, I met another girl, Liu Mengli (played by Mao Xiaohui). In order to understand his father's past, Yun Tianhe joined the Kunxu Qionghua faction with Han Lingsha and Liu Mengli to become a disciple. The Qionghua faction asked Murong Ziying (played by Mao Zijun), who was of the same age, to teach them, and the four became partners. As his life story was gradually revealed, the four people who were originally sympathetic to each other fell into deep pain and confusion, and finally Yun Tianhe joined hands with his best friend to embark on the road of salvation against the sky.
