The name Pei Jiuren was randomly chosen by her father when he retrieved her from the mountain of corpses and sea of blood. For fifteen years, she has been the most inconspicuous secret guard of Dingbei Hou Mansion, licking blood from her knife edge and hiding from the light. Pei Minglang, the legitimate daughter of the Hou Mansion, died suddenly. She disguised herself as a surrogate wife and entered the Zhennan Prince's Mansion as a concubine. She had only one mission - to take the life of the Prince of Zhennan, Xiao Muye. Under Luo Shang, the old blade is hidden close to the body. But when the blade of the blade touched the man's throat, she realized: the dead legitimate daughter did not die in an accident, King Zhennan was not the dissolute waste as rumored, and she, Pei Jiuban, was not an abandoned baby picked up casually. This game of chess has been laid out twenty years ago. Everyone is a chess piece and everyone is a chess player. When the old blade comes out of its sheath, will it cut the enemy's throat, or where he came from?
