The Duke of Zhenguo, Su, died in battle, leaving behind a widowed wife and a weak son, surrounded by political enemies in the court, and the Su family was about to collapse. The legitimate daughter Su Qingci gritted her teeth and cut off her hair, inherited the title of heir apparent as "the legitimate son Su Yun", and entered the court dressed in men's clothing. She resolved the food crisis with her strategies and intimidated the old ministers with her courage. In just three months, she gained the reputation of "The Bright Wind and the Moon", but she happened to offend the most troublesome person in Kyoto - Xiaoyao Wang Xiao Yanzhi.
Xiao Yanzhi is the younger brother of the Holy Emperor. He is arrogant and arrogant. When he sees Su Qingci, he will make things difficult for him everywhere: the imperial hut is broken, the inkstone explodes, and he is "attacked" by bird droppings when he goes out. Su Qingci's "unlucky daily life" is all thanks to him. But no one expected that in an accident on the night of the palace banquet, Xiao Yanzhi would press "Prince Su" on the couch, causing an uproar in the whole court. To prove his innocence, he swore in public: "I like a dog, but I don't like the sissy Su Qingci!"
But later, when the border was in crisis, Su Qingci led the army to go on an expedition, but Xiao Yanzhi abandoned the comfort of Kyoto and followed her all the way; she was poisoned by an arrow, so he took drugs himself regardless of the risk; a political enemy revealed that she was a daughter, and he stood in front of her and pledged his life to her. At the final celebration banquet, Xiao Yanzhi grabbed Su Qingci, who had resumed her daughter's disguise, and asked with a blushing face: "Qingci, do you still lack a dog by your side? The kind that licks dogs."
——It turns out that the bitter rivals on the road to power and conspiracy have long since become each other's best friends.
