"The Tyrant's White Moonlight: in the Beginning, I Was Doing an Autopsy in the Cold Palace, and I Was so Greedy That I Criticized the Male Protagonist."
Su Jiu, a modern highly intelligent female forensic doctor, accidentally slipped into an ancient sadistic novel and became a subjugated princess (cannon fodder female supporting role) who could not survive more than three chapters of the book. The original owner was sentenced to death due to his cowardice. When Su Jiu came back, he was at the "murder scene" where he was framed. In order to avoid suspicion and save her life, she had to reveal her superb autopsy skills, but unexpectedly attracted the attention of the most powerful villain in the book - the bloodthirsty and violent regent Xiao Lin who was poisoned.
In order to survive in the cannibal palace, Su Jiu and Xiao Lin entered into a "contractual love": she would investigate cases and treat illnesses for him, provide him with delicious food (to cover up the smell of medicine), and he would protect her. In front of Su Jiu, he is a "bastard princess" who only knows how to eat, drink and act coquettishly. Behind him, he is a "magic doctor" who holds a scalpel and makes the dead speak. At first, Xiao Lin only thought of her as a useful tool, until he discovered that this "little apprentice" could not only dissect corpses, but also cut through his defenses. When the hypocritical original heroine and conspirator tried to crush Su Jiu to death, the biting "wolf dog" finally showed its fangs: "Touch her? Have you asked about the knife in my hand?"
