Shen Leyao, the third daughter-in-law of Yongninghou Mansion, is a good-for-nothing young lady who is despised by everyone in the manor. She doesn't like to strategize and fight in the house. She spends her days eating, drinking, having fun, and living a Buddhist life. She is regarded as a useless and abandoned child by her family, and is sent to Beiyuan to marry the tyrant Xiao Linyuan who is feared by the world.
After entering the palace, all the concubines in the harem regarded her as a thorn in their side, thinking that her virtue was not worthy of her position. The Queen Mother, who was not the emperor's mother, devoted herself to supporting her niece and nephew, and repeatedly made things difficult and framed her. She took advantage of the tyrant's departure from the palace and killed her in an attempt to seize her throne. Xiao Linyuan returned to the palace to find out the truth. In anger, he threw the Queen Mother into a nunnery and was not allowed to return to the palace for the rest of her life.
At first Xiao Linyuan believed that she was a spy with hidden murderous intentions, but he was moved by her frank and free nature. Shen Leyao seems to be playful and useless, but she has a clear mind and hits the key points every sentence. The war on the border was urgent, and the ministers were helpless. She studied the ratio of food, fire control, and adaptability to the art of war, and came up with a good strategy to defeat the enemy.
Xiao Linyuan followed the plan and went on a personal expedition, winning a great victory and regaining the territory. The civil and military officials of the entire court and everyone in the Sixth Palace were completely convinced and sincerely supported and respected her.
Knowing that she was favored, Marquis Yongning went to the palace with his talented eldest daughter in an attempt to replace her. But in the end, the father and daughter could only be stunned and regretful. The abandoned daughter in the past had already become a legendary queen who was the only favorite of the tyrant and could not be shaken by anyone in the country.
