She was a rock and a seed. He was the reincarnation of an immortal, as well as a wisp of soul left behind by a demon king of the demonic world … She had been sent to the mortal world to help him endure seven tribulations. He had lived his life for her, died for her, loved for her, hated her … After the seventh life, there was no way to find out where she had come from or where she had gone. After three years, the world will be merciful. Once the calamity has passed, everything will be a dream, without the promise of a mountain and a sea, without the promise of death, but the demons in my heart will not be removed, and I will not be able to live and I will not belong to all four sides.
