Various Magical Skills of the Detective System

Since the novels I have read are all short novels that are not enough, I put together various crime-solving magic operations and re-created a slightly longer novel. The protagonist is also a young man who has traveled through time and space and is reborn in a parallel world. He uses the system to create some incredible and wonderful things. Years ago, Fang Zhou, the strongest genius in the police academy and a police star who has solved countless cases, suddenly killed a family of five in a row, causing a sensation in the city. After surrendering, he was diagnosed as mentally ill because he kept claiming that the other party was a ghost! While being imprisoned in a mental hospital, Fang Zhou practiced Taoism, his soul traveled between two realms, and he was invincible with the Five Thunders of Righteous Heart Technique. He was known as the Yin Yang Ghost Detective! Ten years later, his ex-girlfriend Luo Bing, now the most promising star in the police force, was stumped by the Five Elements murder case and thought of Ark. The whole city's policemen begged Ark to come out! The boundary between Yin and Yang is unstable, ghosts are causing trouble in Yin and Yang, and the ghosts of Yin and Yang have returned to the world. Solve the mystery! Kill the resentful spirit! Five elements kill! Refining the blood baby! Secret room murder! Change your life! Start exploring each bizarre case! The introduction is weak, please read the text!
