Jiang Wantang has been in the palace for thirteen years and is the most unpopular concubine in the harem. Even the emperor has forgotten what she looks like. Until she found an unsigned pamphlet in the old archives of the Taiping Pavilion - it listed the names and death dates of twelve harem women by year, and her name was also written on it, next to three words in vermilion: "The third year." She was supposed to die suddenly in the third year after entering the palace, but thirteen years later, she is still alive. Why? Because Mi Zhusi never thought that there would be a concubine with zero bedtime record who could survive without relying on pampering - the only thing she knew how to do was observe everyone in the palace. Now, she knows the secrets of this palace better than anyone else, including the escape tunnel under the imperial city that even the emperor doesn't know about.
Purpose: The orphan girl of the Jiang family married the new emperor who was ten years old in the Yuan Dynasty. She discovered that the history books recorded that there were thirteen concubines who died suddenly, including herself - and she was the only one who survived until the thirteenth year.
