Ring Lock Beauty

Ten thousand years ago, she was the last saint of the demonic world, and was killed by the twelve sects. Before she died, she sealed her entire soul into an ancient magic ring and cursed herself: immortality, never reincarnation, and forever trapped in the ring. Ten thousand years later, the Lord of the Rings was picked up by a young man. She originally thought that this was another greedy person who wanted to use magic power - until she saw the boy's face. That face was exactly the same as the person she loved ten thousand years ago. But she clearly saw that man die in her arms.
