Lin Qiyue bears a strange purple seal and has been eroded by the remnant breath of chaos since she was a child. In order to find a way to solve the curse, she sneaked into the Xuanxiao sect's forbidden area, but accidentally triggered the ancient artifact "Taixu Mirror" and got a glimpse of the blood feud between herself and Xuanxiao's chief disciple Gu Shijiong in the previous life——
It turns out that she is the Zixiao Sword Immortal who used his body to feed demons three hundred years ago, and he is actually the Sword Master in White who personally chopped her soul into pieces back then.
In this life, he was born with the "Nine Heavens Sword Bone" and was destined to slay demons; but the origin of chaos was sealed in her body, which was in conflict with his sword bone.
Purpose: True salvation is not to eliminate darkness but to learn to coexist
