On that day, she jumped into the blazing flames, willingly entered reincarnation, and gave up all her cultivation, just to prove that there is no right way in the world, and that the world is following the evil way.
On that day, he was willing to give up his soul, abandon the world, and would rather lose his soul just to save the one he loved, but he didn't realize that she was supposed to be an immortal demon, so how could she fall into reincarnation in a blink of an eye.
On that day, she, who was originally weak, had a determined gaze, raised her sword and killed herself in front of everyone, as if it was happening again thousands of years ago. His beloved, but unable to save him.
On that day, everyone returned to their positions, and the sea changed. She has become calm and self-possessed, and has learned the ways of the world. He was still waiting there to see if he could take her back.
