Good news: Lu Qingyan, the overlord of the City Bureau's Criminal Police Brigade, traveled through time and did not die. Bad news: Dressed as the infamous Madam Yazhai of Black Wind Village, she was at the scene of a murder at the beginning. Worse news: She has no system, no space, not even a forensic toolbox! It all relies on a pair of naked eyes and hard-core knowledge of modern criminal investigation to solve the case. In order to survive in the murderous village, Lu Qingyan rolled up his sleeves and returned to his old profession. After examining the bones, checking the footprints, and making profiles, a homemade version of the luminol reagent plant ash can bring to light the old injustice cases in the village. The originally vicious bandits instantly transformed into little fanboys, each one saying "sister-in-law is wise". In particular, Huo Jingyuan, the rumored mastermind who killed without batting an eyelid, became her number one fan. He poured tea and water, pinched his shoulders and beat his legs, with stars in his eyes: "Madam solves cases like a god, I admire her husband!" Lu Qingyan thought he was getting the heroine script of "I engage in criminal investigation in ancient times". Until one day, she woke up in the middle of the night and found that the boss who "purely admired" her was stuffing a bloody weapon under her pillow. Early the next morning, Huo Jingyuan smiled innocently with dark circles under his eyes: "Madam was talking in her sleep last night, saying that there was a fatal clue on the murder weapon, and I specially found it to make Madam grow eyes." Lu Qingyan: "..." God is so sleepy! You're such a sleazy man, you actually cheat me every night by talking in my sleep and using your labor force for free? ! Let's see how the hard-core female detective and the scheming master work together to fight against the evil in ancient unsolved cases!
