Bai Yueguang Doesn't Think It's Possible

Su Tang transforms into the female partner of Bai Yueguang in a fairy tale about sadomasochism. According to the setting of the original work, as the male protagonist's junior sister, she will sacrifice for him early. Years later, the male protagonist will become the leader of the world of cultivation and a world-famous swordsman. He will encounter a female protagonist who looks similar to her, and will treat the female protagonist as her substitute, and start all kinds of bloody plots that abuse the body and mind. After many hardships and dangers, the male and female protagonists finally got married. However, in order to save the common people, the male protagonist did not hesitate to self-destruct and seal the villain, which made the whole book BE. Su Tang: "..." Su Tang thinks this won't work. After time travel, in order to avoid being killed in the plot, she stayed away from the male protagonist's gang and found a tall, handsome, passerby Master A with average cultivation. She practiced hard and planned to leave the sect after learning some skills. Later, the master's identity was accidentally revealed, and Su Tang discovered that he was actually a demon. In order to survive, Su Tang said on the spot: "Master, there is no need to silence me. I have been yearning for the Demon Realm for many years." The master was very calm: "Why?" Su Tang knew that the villain in the original work who forced the male protagonist to self-destruct and the demon king Xie Yan who would become a powerful figure in the world many years later had already become famous. More than half of the three thousand demon gods had surrendered, and he was about to unify the entire demon realm. Su Tang made nonsense: "Because I admire Lord Xie from the Demon Realm." The master's expression was subtle: "..." Later, the master temporarily left the sect due to something else. Before leaving, he asked her to practice well and said that he would come back to pick her up in a few years and that she might be able to get what she wanted. Su Tang sent his master away in confusion, and soon ran away from the sect and went to practice in the secret realm for hundreds of years. He became a free and unhurried immortal in the outside world, living leisurely and happily. When I woke up, a friend came to visit and brought the latest news about the world. The armies of the Demon Realm spread in all directions, and the Demon Lord's divine power reached the sky. No one could defeat him. The famous Sword Immortal was also defeated by him. The rulers of the Nine Realms were all defeated and bowed their heads in trembling. The friend suddenly looked strange, "I heard that the Demon Lord once looked for a person named Su, who seemed to be his disciple?" Su Tang: "?" Not long after, she saw the demon king who looked exactly like her master on a battlefield littered with debris. Dark clouds lay across the sky, the peaks were dim, countless monsters prostrated on the ground, and thousands of gods and spirits knelt down in silence. A handsome man in a black shirt slowly walked up to her, raised his hand to hold her face, gritted his teeth and whispered: "You promised to admire me?" ※The text and title may be changed, but the core message remains unchanged. ※Unorthodox cultivation, high magic fantasy, mixed elements.
