I, Cao Mengde, Actually Traveled Through Time and Became Lin Daiyu?

In the twenty-fifth year of Jian'an, Cao Cao died of a headache. When he opened his eyes, he became Lin Daiyu who went to Rongguo Mansion. The sixty-six-year-old hero is trapped in the body of a fourteen-year-old girl, and his two souls coexist with Daiyu, from games to mutual shaping - he teaches her not to bow down when settling scores, and she lets him let go of killing and regret. The day his obsession disappeared, he returned calmly; and she was reborn and carved out her own way of life in this world.
