After a tragic car accident, Lin Wanxing and her scumbag ex-boyfriend Wen Yan both died. However, they did not want to open their eyes and traveled together to the Zhenguan period of the Tang Dynasty.
He became Tang Taizong Li Shimin, a man of great talent and strategy, with a vast empire and a harem of three thousand beauties.
Instead, she became the first queen who was gentle and virtuous in the history books, but was destined to die young - Changsun Wugou.
Facing the unpredictable-looking emperor on the dragon throne, who was both familiar and unfamiliar, Lin Wanxing had a sword hidden in his sleeve, but his smile was gentler and more virtuous than anyone else's. In this life, she will no longer be a virtuous queen, let alone anyone's substitute.
