I'm so Old, I Really Can't Be a Police Officer!

Hello everyone, my name is Jiang Shuaikun, also known as Huang Mao in Jianghu. Once he traveled to a parallel world in 2000, he became a criminal investigation genius. The police rank is not high, but the status is very high. He has repeatedly solved major and special cases. His experience is longer than my life. God knows, I am a young person, I did not graduate from junior high school, and I can only write the word "regret" in pinyin. You can't be a police officer at all! If you encounter a speedster gang, you will be directly blamed. A serial case of missing female workers, a case of trading poor students, a case of trafficking in maternity hospitals... While walking on thin ice and pretending to be cautious, one case after another was solved accidentally. It seems that solving the case is not that difficult!
