It is rumored that there are three sects in the world, the Xuantian Sect, the Soul-Eating Sect and the Xianyin Sect. They are respectively in charge of the three great artifacts of the Wentian Sword, the Beast Jade Pendant and the Ling Kong Hou. Each of them has extraordinary potential, waiting to be discovered and put to good use by those who are destined to do so. The three sects were entangled in grievances, and Xianyin Valley suffered a sudden massacre. Before his death, the leader Wenzhu passed the title of leader to his daughter Qiangwei.
Qiangwei has been in charge of the sacred instrument Linghou since she was a child, also known as the "Forgetting Qin", which can cut off the love in the world. A "Forgetting Song" can erase past memories, and can even summon the divine bird Phoenix. From then on, Qiangwei embarked on the road of revenge and revitalization of the sect, but who exactly made her play the song of forgetfulness? Who was it that awakened her dusty memory? Is all this a well-planned conspiracy? Or an unspeakable love?
