The Demon Lord's Legend: Red Bones

Serious Version 1: Everyone knows that beneath the Great Dao, the world is divided into six realms: Gods, immortals, demons, humans, devils, and ghosts. Each realm has its own ruler. Ever since Pangu created the world, the six realms have remained clearly distinct, each minding its own business. But the appearance of Hong Gu, ruler of the Demon Realm, shattered all that. People learned that humans could become demons, or devils. But first, they must endure tremendous injustice and unbearable suffering before they can become the supreme ruler of the Demon Realm. There can only be one supreme ruler, and there is only one Hong Gu. Anyone who trespasses in my Demon Realm will be killed without mercy. I am Hong Gu, ruler of the Demon Realm. Serious Version 2: Hong Gu had never imagined that even she, the most noble and distinguished princess of the Jiang Kingdom, could be schemed against until she had nothing left. She had never imagined that, as a woman, she would lose her kingdom and see her homeland laid waste because of another woman. Least of all had she imagined that she would be reborn in such a tragic way. She watched with her own eyes as her body was left in the wilderness. She watched as that woman nestled in another man's arms, laughing and chatting happily. She watched as the enemy kingdom grew more and more ruined and decrepit. A thousand years passed in the blink of an eye. Hong Gu had long since forgotten her original name, but she had never forgotten that woman. She would find her, ask her why, and then kill her, sparing no cost to erase her from this world completely. She is Hong Gu, ruler of the Demon Realm. Serious Version 3: The kingdom has fallen, but its rivers and mountains remain. Where is my beloved? Mo Zichu had never known that the proud, peerless princess, so lofty and radiant, with a smile as bright as the summer sun, would fall in love with her. Nor had she imagined that someone like her would meet such a tragic end. It was only one mission, yet she incurred a debt she would have to repay over countless lifetimes. "Everything begins with fate, is born of fate, and perishes by fate." "Master, if that is so, then I will repay her over all my lifetimes. I will stay by her side, always." "She has committed so many sins that she cannot possibly atone for them alone. If she cannot survive this trial of life and death, her soul will be scattered..." "Who wants your company? I, Hong Gu, have been alone all my life. What I love most is hearing humans cry out in despair and pain. What I love most is tasting every agony and torment this world has to offer. What do you amount to? Stop flattering yourself!" "My life has been a joke. I fell in love with the wrong person and committed so many sins. Even if my soul is scattered, I have no regrets." "No! Hong Gu!" Please note before reading: 1. One-on-one romance, primarily from the receiving partner's perspective, with lovers who torment each other. Proceed with caution if that's not your thing. 2.
