Transmigrated into an Ancient-Era Tyrant

[First book, with a somewhat old-fashioned plot] Blurb: Le Qing transmigrated into a book, becoming the villainous tyrant in an old-fashioned Mary Sue novel, whose rule the heroine was destined to overthrow. She was dressed as a man, and was even the heroine's unattainable first love. In the end, one of the heroine's admirers stabbed her three times, leaving six holes in her body and not even a whole corpse. To get home, Le Qing had to complete an almost impossible mission without changing her character. With no other choice, she put on three secret identities and dutifully followed the plot. As the first identity, a wealthy young gentleman, she played the hero and saved the beauty, using every trick to flirt with the heroine... As the second identity, a pampered young eunuch, she constantly stirred up trouble, punching the male lead and kicking the male supporting character... As the third identity, a cruel young emperor, she magnanimously and diligently raised the villain... At last, after completing all her scenes, Le Qing successfully faked her death and escaped. But the System suddenly issued an emergency warning: the small world was about to collapse. Forced to return to the novel, she became a female official in the palace. Except... wasn't the plot supposed to go differently? As she attended the emperor, the aloof empress stood behind her, silently tightening her grip on the chains in her hand. The inscrutable look in her eyes made Le Qing tremble with fear... As she rested in her bedchamber, a prodigious young general climbed over the wall in the middle of the night, stood by her bed, and looped a short whip around her wrist. Then he smiled and asked if the whip in his hand looked familiar... As she delivered the empress's orders, she accidentally discovered a secret room hidden in the side chamber of the Jade-Faced King of Hell's study. Before she could react, she heard a key turning in the lock behind her. The door was locked... And the culprit was smiling at her through the crack... Le Qing, the retired emperor and notorious heartbreaker: ...This feels like a familiar love-triangle showdown. #I only raised secret identities, so why do they call me a heartbreaker? # #Can I pick up my secret identities after they've been exposed? # The heroine is adored by everyone, and her admirers include, but are not limited to, those mentioned in the blurb. Theme: A beautiful future lies ahead.
