During the Dajing Dynasty for more than three hundred years, there was a secret organization hidden under the court - the Burning Marks Department. It is not bound by the law, does not care about good and evil, and specializes in erasing those who "impede the imperial power": generals with great achievements, palace servants who have glimpsed the secrets of the palace, and ministers who hold the secrets of the previous dynasty... These people are removed from the history books and disappear completely from the world, as if they never existed.
Shen Qingci is the youngest palm seal officer of the Pinhen Division. He has excellent swordsmanship and a cold heart. He personally ended the "existence" of seventy-three people in three years without ever wavering. Until one mission, she discovered that hidden among the relics of the obliterated people was a "Black Iron Token" that only the Print Officer of the Department of Destruction had. The owner of the token was actually her sister Shen Qingyuan, the former Print Officer, who "died" of illness five years ago.
As the investigation deepened, Shen Qingci was shocked to realize that his sister's death was not an accident, and the existence of the Marks and Traces Department was by no means as simple as "eliminating hidden dangers." It is the sharpest knife in the hands of the royal family, and it is also a fig leaf to cover up the "dragon seed was changed" a hundred years ago: today's Emperor Dajing is actually a puppet supported by his relatives, and the real royal blood has long been lost among the people. It was precisely because of her discovery of this secret that her sister was labeled a "traitor" and was brutally silenced.
On one side is the dynasty he has been loyal to since childhood, and on the other side is the blood feud and the shocking truth. Shen Qingci is walking on the tip of the knife. He has to deal with the informants within the Department of Punishment, find the true prince who is living among the people, and face the torn identity of "Eraser" and "Guardian". In the end, she must make a choice between "loyalty to the old master" and "bringing order to order", and the names of those erased by the Department of Destruction...
