The Kyushu Continent is bounded by the sea, and the Nine Kingdoms are based on it. There is the fairy island "Fuyao" in the southeast corner, which is the starting point of the fairy magicians.
According to legend, spiritual power permeates the world. Although ordinary people have it, they cannot control it. Only a handful of talented people can introduce the spirit into their bodies and become "immortal magicians". Those who pass the Fuyao test are rare.
Pei Huaijin is the youngest among them.
However, the immortal sorcerer's constitution is inherently weak and needs to be bound to a shadow guard to protect him for life. Other people's shadow guards may be spirits, puppets, or demon souls, but he has a living young man named Jiang Ce who is cold and taciturn and possesses a sharp sword.
