After generations of war between humans and demons, only Qiu Sheng was left - the last bloodline. Carrying the grievances and resentments of her ancestors for generations, Qiu Sheng accidentally broke into the spirit clan and also broke into the heart of the spirit master Li Yuan. In this troubled world, no one can live clearly in the world. Who is right or wrong? Who is good and who is bad? There is no definition. Everything will return to chaos. Will Qiu Sheng, an amnesiac girl from the Demon Clan, and Li Yuan, the cold-blooded ruler of the Spirit Clan, achieve a positive result?
Concept: In some things, there is often no clear boundary between right and wrong, good and bad.
