In her past life, Su Qinghan blindly trusted the Qingyun Sect. Her younger sister, Su Ruanruan, was stripped of her bones and refined into medicine by Lin Jingfeng, and the Su family was exterminated. Reborn back to three years prior, she tears up the recruitment order and strictly prevents her sister from approaching cultivators. Yet Ruanruan picks up the severely injured Demon Lord, Ye Wujiu. Lin Jingfeng's night raids, soul searches, the immortal sect grand competition, and blood sacrifice arrays follow one after another. Relying on her past-life memories, Qinghan maneuvers through them, while Ye Wujiu secretly protects people in the guise of a handyman and security captain. Ultimately, Lin Jingfeng's divine soul is cast into the Nine Nether Demonic Fire, and the defeated of the immortal sect become laborers for the Su family. Ye Wujiu asks to marry Ruanruan with twenty copper coins, seals his cultivation to marry into the family, and moves with the sisters to Qingshui Town. Qinghan buries the red string of her past life, lets go of her obsession, and protects her family.
