Lin Wanqiu unexpectedly came to the ancient palace, only to find that it was already a desperate situation for time travellers. In the past three years, ninety-nine fellow villagers had been treated as threats by the suspicious emperor because of their words, deeds or thoughts that were different from the times. In order to survive, she put away all traces of modernity, disguised herself as an ordinary palace maid, and carefully served the abandoned concubine in the cold palace. She remained tight-lipped about the temptations of the outside world and carved mediocrity into her daily life. The continuous sitting system in the palace allows everyone to supervise each other, and the little eunuch Xiao Shunzi who is bound to her becomes her only bond in the palace. She witnessed with her own eyes that fellow villagers were severely punished for their eagerness to show off their talents and desire for the Phoenix Seal.
