Lin Wan, a modern social animal, was unexpectedly reborn during the Kangxi period and became a girl to be drafted. He originally wanted to live a low-key life, but by mistake, he was accused of marrying his fourth elder brother Yinzhen, who was known as the "cold-faced king", as his direct descendant Fujin. Full of modern thinking and desire for survival (as well as foodie attributes), Su Wanwan began to adapt to life in the fourth master's backyard. With a unique perspective (and complaints), she observed the turbulent undercurrent of fighting for the heir in Kowloon, and used modern wisdom to solve big troubles in ancient times (and create small troubles). Not only did she accidentally attract Yinzhen's attention, but she also gradually gained a foothold in the torrent of history. From "preserving life and prospering the Jin Dynasty" to being a "virtuous wife" and then becoming a "virtuous queen" after Yinzhen ascended the throne, she and Yinzhen grew up together in mutual exploration, support and deep love. They wrote a unique legend of the emperor and empress in a relaxed and humorous way against a serious historical background.
