Lu Changping, a sovereign ruler, exhibited remarkable intelligence and military prowess after his ascension to the throne. His only flaw was being overly fond of his sister, to an extreme degree in his later years. The neighboring tyrant, known for his murderous and cold-blooded nature, had already killed three fiancées. Hearing that Lu Changping’s sister was the most beautiful woman of the era, he repeatedly sent proposals to marry her. Refusal might lead to a military confrontation between their nations. After much deliberation, Lu Changping finally decided to disguise himself as a woman and replace his twin sister in the marriage alliance. Unexpectedly, the tyrant fell deeply in love with him at first sight. Not only did he make him the Empress, but he also expressed a desire to have an heir with him? ===== Xie Xuan Yuan, striving for unification, instigated war to dominate the world. Hearing about the enemy emperor’s excessive affection for his sister, Xie harbored malicious intentions and requested a marriage alliance. Everyone anticipated the princess from the marriage alliance to be found dead in the cold palace, but contrary to expectations, the tyrant devoted himself every day to winning over the beauty. Unfortunately, the “bashful and demure” beauty always found reasons to refuse sharing a room with him. One night, Xie Xuan Yuan, unable to contain himself, drugged the beauty’s drink, only to discover that the beauty was a man, and once undressed, was even more masculine than himself… Ten months later, Xie Xuan Yuan, with child in tow, confronted Lu Changping, threatening fiercely: “You owe me an explanation for that night. If you don’t give me one, I’ll kill your son.” Lu Changping: “Would you really? That child is also yours!”
