When Working as an Errand in the Hong Kong Comprehensive Service, Being Handsome Is the Original Sin, and the System Is a Divine Punishment.

Time traveled. Yin Yiying found that this world seemed slightly different from the original world, but it was still so familiar. First, he discovered that there was a psycho with a very angry boss face and his sister, the Supreme Mage, in his jurisdiction. Soon, another veteran police officer who was known to be a good singer was transferred from the jurisdiction. He partnered with a female police officer who was known to be a good singer. The purpose may be to dominate the Hong Kong music scene. When the "Rainy Night Butcher" case shocked the whole of Hong Kong, Yin Yiying finally confirmed that she accidentally entered the set of "Psycho" and came to the world of Hong Kong variety shows. I thought I could live a relaxed and exciting life with the system and knowing the plot, but when Yin Yiying discovered that there was a Crimaster detective ranking APP on her phone, and the Japanese on the ranking was no longer Noda Hao, but a high school student named Kudo Shinichi. . . He found that things seemed not that simple. Welcome to the world where detectives gather!
