Ling Shuang was accidentally bound to the "Interstellar Palace Fighting System" while performing a mission, and was thrown into the imperial palace on the verge of collapse. She had only one mission - to assist the autistic emperor Mo Yuan to stabilize the imperial power.
The tasks issued by the system are becoming more and more outrageous: "frame loyal ministers to gain trust" and "exploit the male protagonist's weakness to achieve goals." Each execution makes her struggle between mission and morality.
In the court, the cunning prime minister plots and seizes power; in the harem, the green tea concubine pretends to be caring but actually poisons her; and beside her, the white-eyed maid turns against him after receiving benefits.
Ling Shuang carefully approached Mo Yuan while tearing the villain apart with her own secret agent methods. When the autistic emperor is finally willing to open his heart to her, the system throws out the ultimate mission: "Sacrifice the male protagonist to preserve the interests of the Interstellar Alliance."
Agent Yu Jie tightened her grip on her weapon: "My mission is always determined by myself."
