Pei Yun, the immortal who slayed the demon king, had been hiding in the Kunlun Mountains for thousands of years, but suddenly he wanted to accept a disciple. Fusang, a mortal, became a disciple and learned the art.
Face to face with the master day and night, practice day and night. But gradually he discovered the master's hidden secret.
Seven hundred years ago, when the Xie family was exterminated, Pei Yun appeared at the scene holding his natal sword.
Thousands of years later, demonic energy appears frequently in the human world. Is the demon king alive or dead, or is he secretly hidden by an immortal?
Fusang didn't want to care about these things. He just wanted to face his master day and night as before and never be separated.
Intention: love
