On the autumn night of the twenty-sixth year of Yongchang, Lin Wan knelt outside the secret government office and knocked on the door of the powerful minister Xiao Jue with a blood-stained iron plate. Disguising herself as a man, she is the calm and wise "Inspector Lin"; hiding a deep blood feud, she is the loyal queen who bears the injustice of exterminating her family. Three years of companionship, from suspicion to trust, from use to deep love. When his identity was exposed and the old case was reopened, he knelt in the golden palace and said: "I had known she was a woman, and I would have sacrificed all my merits in exchange for a retrial of the Lin family's unjust case." A revenge that spanned seven years, a deep love that cannot be tolerated in the world. The cold-faced King of Hell and his "male" staff write legends with their machinations and sincerity.
