The "Ghost Face Army" of the previous dynasty was brutally massacred, and the only surviving top female secret guard, Shen Wu, disguised herself and infiltrated the palace in place of a palace maid who died tragically in order to find out the truth. She originally wanted to lie low and dormant, but due to her keen insight, she was forced to get involved in a strange harem murder case: a headless corpse in a dry well in the cold palace, blood letters appearing out of thin air on the body of a beloved concubine, the sound of opera in the imperial garden in the middle of the night... During the investigation process, Chen Wu found that all the clues pointed to the mysterious man Pei Jingzhe, who was known as the "9,000-year-old" adopted son with all the power. From testing each other and hiding murderous intentions, the two discovered that each other was actually an "ally" who had been separated many years ago. They finally joined forces in the intrigues of the palace and used wisdom and force to tear apart the gorgeous robes. The name is "Palace Fighting", which is actually a "hunting" and pull down all the high-ranking murderers.
