Su Qingjian was born with the rare Five Element Spiritual Roots, and the nightmare of her parents' brutal deaths haunts her like a shadow. The Water Spirit Jade was left to her by the old immortal before he passed away. It is both a precious treasure and the bond that governs her fate. It can nourish her spiritual roots and heal her wounds, yet it also hides a curse that continually pulls her toward the boundary between the path of immortality and the demonic way.
She joins the Canglan Sect, thinking she has found a place of refuge, only to discover schemes lurking throughout the sect. The First Elder plots against her in secret, fellow disciples maliciously frame her, and even the master she once revered harbors layer upon layer of secrets. As the truth behind the massacre of her family gradually emerges, she realizes none of her suffering was ever a coincidence.
The immortal sects speak of the rules of the Heavenly Dao, yet it has never protected her. With the Devouring Sword in hand and a sea of blood-deep vengeance in her heart, she refuses to let fate control her. When strange phenomena appear during the Spiritwater Trial, she confronts the traitors and tears away the hypocritical mask of the immortal cultivators.
What is an immortal? What is a demon? The world judges good and evil by one's origins, but she will defy the Dao. She seeks no mercy from the Heavenly Dao and cares nothing for worldly judgment. Whether she takes the immortal path or the demonic one, the choice is hers. With one sword stroke, she will break through the shackles of the heavens. From now on, there is no distinction between immortal and demon. Her fate is hers to command, not Heaven's!
