In the matriarchal kingdom of Liulian, facing both internal and external challenges, the royal counselor proclaimed, "The world will perish if six daughters are born." Coincidentally, General Gu gave birth to six daughters. In order to save the youngest daughter, the Gu family falsely claimed to have a son. Their daughter, Gu Rong, of marriageable age, disguised herself as a man and married "good friend" Princess Yun together with her childhood friend, Shen Meng Chui.
