I Gave the Sadistic Script to the Male Protagonist

Su Yao had a dream one day about his miserable life. The well-bred younger brother would stab her in the back and use her blood to save Li Yanran; Her fiancé only regarded her as a substitute and broke off the engagement with her in full view of the public; She was still unable to love her cold master. In the end, her obsession turned into a demon and she died tragically under his Jiuling Sword. After Su Yao woke up, she was afraid that she would end up like this, so she decided to strike first. She stabbed her junior brother before he stabbed her, "I'm sorry, junior brother, in fact, your hard work can also save her." The younger junior brother looked at the knife on his chest, his heart broke, and he cried blood: "Is she more important than me?" She hurriedly got rid of her fiancé before he broke off the engagement, "You are very good, but I am not worthy." The fiancé was paranoid and smiled brokenly, "Do you have someone outside?" She hurriedly put her cold and desolate Master to sleep before the Master could kill her. When she woke up, she left a note: "Master, my obsession has disappeared. Please say goodbye." Su Yao ran away. She ran to the demon world and hugged the demon king's thigh. In the dream, she and the Demon King were getting along quite well, so there shouldn't be a problem in making ends meet. As a result, her cold and snow-like master entered the Demon Palace with Jiuling Sword, his eyebrows were red, he smiled and shed tears of blood, "Su Su, come to me, don't force me to kill him..." How did her cold master... Become possessed by a demon? #Disaster always slows me down# Purpose: Learn to think reversely.
