After Rebirth, I Raised a Demon King Who Killed Me with His Own Hands

In her previous life, he was her younger brother whom she picked up from childhood. She taught him calligraphy and swordplay, and cooked longevity noodles for him for three hundred years. On the day she failed to escape the tribulation, the sword she took for him with her own hands penetrated her heart. He said: "Sister, you are blocking my way." When she died, she heard his last words: "In my last life, you lied to me first." She doesn't understand. She rushed into reincarnation with that question, but was sent back to the Black Wind Valley three hundred years ago - the snowy night when she first picked him up. He huddled in the pile of dead people and bared his teeth at her, but there was a flash of light in his eyes. He also came back with memories. She should kill him. But she remembered the 30,000 names on the Sansheng Stone - he killed her once in each life and carved a name. In every life, he saves her. She can't kill him. She carried him on her back and walked into the wind and snow. In this life, she wanted to untie those knots one by one before he showed his fangs. What she didn't know was that he had been waiting for her to wake up for thirty thousand years.
