The Days and Nights of Being Imprisoned by the Yandere Regent

[1V1+shuangjie+wearing+yandere+black-bellied+crazy] [Stunningly morbid and paranoid male protagonist + sober female protagonist with a strong desire to escape] Ye Wuyue slipped and fell into the water, accidentally traveled to an imaginary ancient time, and became a "missing girl" in a brothel. She was forced to give her a dose of red medicine by an unscrupulous madam. Fortunately, she was rescued from a brothel that day by a big shot she couldn't afford to offend. However, when she was brought back to the magnificent mansion, she went from a small cage to another large cage. The big shot has a face that brings disaster to the country and the people, and has an extraordinary charm; he has overwhelming power, controls the destiny of the country, and looks down upon all living beings as ants; but he is actually a demon with an extremely twisted mentality. He took her away from the brothel just because he thought she looked like the only god in his heart. He was born with strange eyes, no one dared to look directly at him, and he was regarded as ominous by the world. On the night he entered the palace, he said coldly to her: "You are the second person who dares to look directly into my eyes like this." Ye Wuyue was so frightened that he thought his life was in danger. However, he just used her fake as a product to vent his anger, and always tortured her in different ways. He even did not hesitate to use his body as bait to constantly stimulate and humiliate her. Ye Wuyue: No, no matter how beautiful you are, you can't sink! She ran away resolutely and finally succeeded, but the gears of fate did not let her go and turned them together again. Unexpectedly, this time she accidentally discovered a shocking secret - her substitute was actually the... Sister he had been looking for all this time? (Key point: This is not an ordinary time travel!)
