Modern martial artist sisters Lin Qingge and Lin Qingwu are unexpectedly involved in a car accident and transmigrate to a general's residence. Their statuses are turned upside down: the elder sister becomes a noble legitimate daughter, while the younger sister is reduced to a lowly concubine-born daughter. Delighted to find that they still retain their memories from their previous lives, they have no time to adjust before being swept into a vast conspiracy. Corrupt officials at court secretly collude with the Northern Di, plotting to use the bloodline of “twins” to unleash an ancient forbidden art and plunge the world into chaos.
As their investigation deepens, the sisters are shocked to discover that they are the reincarnations of twins from three hundred years ago, and that the curse from that time still haunts them. In this life, their mother was also one of a pair of twins, but she died tragically in a struggle for power. Even more perilously, the Northern Di's high priest has already planted “inner demons” within them, maliciously driving a wedge between the sisters and leading them step by step toward the abyss of killing each other.
When Lin Qingwu's soul scatters into the River of Rebirth to save her sister, Lin Qingge finally uncovers the cruel truth. The so-called “curse of the twins” is nothing more than an evil immortality spell created by an ancient priest. In every generation, the surviving twin becomes a vessel for the priest's resurrection, and in this life, Lin Qingge is the one chosen. Before her lies a choice: become a vessel and allow the evil priest to rise again, or break the curse, avenge her sister, and rewrite the fate of the twins…
