Ying Xingchen was inexplicably transported to a world of cultivation after a car accident. She accidentally saved the villainous male lead. She had planned to kill him with one sword and eliminate future trouble, but her master stopped her. After thinking it over, she decided that if she couldn't kill him, she might as well cling to him. So when the male lead made no progress in his cultivation, she found him cultivation methods. When he had no life-bound weapon, she sacrificed her own for him. She finally managed to raise him into an upright young man, only to discover that the male lead had been reborn! Not only had he secretly taken command of the demon clan, he had also killed her master. Ying Xingchen couldn't accept it and tried to kill herself, but her junior brother rescued her. She unexpectedly awakened her memories and realized that she had belonged to this world in her previous life. This time, she hadn't transmigrated by accident. She was here to change the tragic ending she'd suffered before. Through her investigation, she discovered that the greatest villain wasn't the male lead, but the gentle junior brother hiding by her side.
