Story of the Development of Demon God

When we first met, he was an immortal and she was just an inconspicuous stone. The first time we met was a farewell. You gave me a hundred years of comfort, and I am willing to exchange my life for you. The second time, after a hundred years of hard pursuit in the human world, who would have expected that she would be reincarnated as a princess and she would still be unpopular. She had no choice but to die as soon as she met her. Well, you unlucky girl. This time he decided to take her as his disciple and teach her spells, but who knew that he would put his own heart into it. A hundred years of companionship, a person and a stone. The figure that is as white as dust in the crimson sky fills the sky, standing on the exposed stone every day, overlooking thousands of mountains. She swore that she would never let him be lonely again. Accompanying each other day and night, staying together in silence, finally came to an end. In order to save him, she made a huge mistake. However... "You know you are wrong." She turned around and jumped into the Millennium Cold Pond. She didn't want him to be embarrassed... What she left him was ten thousand years of loneliness.
