Unsolved Mystery? Sorry, I Broke the Situation at a Glance

My name is Chen Fei. I dream of being a detective, but I am so poor that I live in a rental house. Unexpectedly, a flight turned into a chamber of death! A luxury class passenger was mysteriously poisoned, and the murderer disappeared out of thin air, causing panic on the entire plane. I exposed the tactics on the spot and forced the killer to jump out of the plane and flee! After becoming famous in the first battle, a mystery came to his door: A mass poisoning in a hotel, a serial hair-dying case, a secret room murder, a ghost in the police station... Every case is so weird that there is no solution, and every time life hangs by a thread. I opened a Qingtian Detective Agency, specializing in solving murder cases that others dare not take on! The murderer thought it was perfect? Sorry, all tricks are rubbish in my eyes!
