He seems to be nothing more than an ordinary teahouse attendant, yet with thousands of years of experience, he guides a down-and-out swordsman, saves a dying great demon, and sees through the true nature of ancient treasures. He no longer seeks to restore his power as quickly as possible. Instead, he lives like an ordinary man, experiencing the joys and sorrows he once overlooked.
Immortality brings not freedom, but endless loneliness, estrangement from the times, and the covetous attention of every faction seeking the “secret of eternal life.” Through repeated falls back to zero and resurgences, the protagonist must uncover the astonishing game being played behind immortality.
