Nineteen years ago, the Qionghua Sect used the double swords of Wangshu and Xihe to trap the demon realm and seize spiritual power, triggering a war between humans and demons, with heavy casualties on both sides. Due to their disagreement with the Qionghua Sect's cultivation philosophy, the disciples of the Qionghua Sect, Yun Tian Qing and Su Yu, left Qionghua and went to Qingluan Peak, where they gave birth to their son Yun Tian He. Not long after, Su Yu passed away. The young Yun Tian He is not aware of his parents' past, and his father, Yun Tian Qing, also passes away due to illness, leaving him to grow up alone on the mountain. Yun Tian He runs into Han Ling Sha, a young lady who breaks into his parents' tomb, and they go down the mountain together to search for his parents’ past. In the midst of their journey, they get acquainted with another lady, Liu Meng Li. In order to understand his father's past, Yun Tian He, along with Han Ling Sha and Liu Meng Li, become disciples of the Kunxu Qionghua Sect. Qionghua Sect assigns Murong Zi Ying, who is similar in age, to mentor them, and the four become companions. As his background is gradually revealed, the four of them, who have originally sympathized with each other, are plunged into deep pain and confusion. In the end, Yun Tianhe joins hands with his close friends and embarks on the path of saving the world by resisting his fate.
