Demon Ultimatum: My Demon Hunting Assistant Is so Awesome

Suspense reasoning, urban romance, cute assistant, strong heroine, (don't read it as a mystery novel!!!) The case of the absolutely secret room without any logical solution: the deceased in the secret room had a knife in his heart, and surveillance actually led to the establishment of the absolutely secret room The rational detective's worldview collapsed, and his assistant flipped through his own "Monster Encyclopedia": "Brother Changqing! It must be the monster who sews human skin!" Wang Changqing looked at the squirming things that were neither human nor ghosts in front of him: "After the founding of the People's Republic of China, will the Basic Law still be followed when monsters become spirits?" Su Yuting held the candied haws in her mouth and raised her hand: "My nose can smell evil spirits~ Do you want to help?" And when the second case came to our door unknowingly, He was shocked to realize: the first absolutely secret room case was just the appetizer for the urban monster story... "So, you must always take this lovely assistant with you. Otherwise, if you encounter such a case in the future, what should you do, Brother Changqing?" "You? You are at best a personal demon detector."
