Ye Chen, a genius disciple of the Qingyun Sect, descends the mountain to gain experience and saves You Yue, who is gravely wounded, unaware that she is the Holy Maiden of the Netherworld Sect. The two struggle between the conflict of good and evil and the feelings blossoming between them. Li Youming, the Netherworld Sect’s master, controls Ye Chen with a “heart-corroding poison,” while the Immortal Maiden Leng Yue discovers that You Yue is actually her biological daughter. After the upheaval in Hundred Flowers Valley, rumors within the sect, and tribulation lightning and inner demons, Ye Chen finally forms a sword infant. You Yue risks her life to protect him with a Netherworld blood pact. In the end, Immortal Maiden Leng Yue sacrifices her cultivation for her daughter, and the war between good and evil comes to a temporary halt. After enduring life and death together, the sword heart and the orchid of the Netherworld wait for the flowers to bloom on Qingyun Mountain.
Looking forward to the update
