After staying up late to watch a time-travel drama from the Qing Dynasty, Su Yao, a modern society animal, woke up and traveled to the Kangxi period, becoming the Wanyan family who was about to be married to the 14th prince Yinqi. Su Yao is a history buff and knows the history of Kowloon's struggle for heirs well. She is well aware of the bloody turmoil in the future and just wants to keep a low profile. However, she does not want to attract Kangxi's attention by accidentally spilling her drink at a palace banquet. Fortunately, she was clever and used modern humor to resolve the embarrassment, which impressed Kangxi deeply.
On the other side, the fourteenth elder brother Yinqi was originally a free and uninhibited prince with little interest in political struggle, but he was involved in the whirlpool of Kowloon's fight for the heir. When she first met Su Yao, she was attracted by her unique words and deeds. Su Yao also got along with Yinzhen and found that he was not as reckless and impulsive as historical records, but had his own ambition and gentleness.
As they got along more and more, the relationship between the two warmed up. Su Yao relied on modern knowledge to help Yinqi solve many problems, such as improving farming, designing novel objects, etc., Which not only made Yinqi appear in front of Kangxi, but also made the relationship between the two deeper. Just when they thought they could live a stable life like this, the eldest elder brother, second elder brother and others began to be wary of Yinqi, and the lives of Su Yao and Yinqi were gradually involved in the undercurrent of palace struggle.
