On My First Day at Work, I Used My Ex-Girlfriend to Boost Sales

Duan Feng is desperate to prove himself and earn a permanent position. While searching for criminals, he runs into his ex-girlfriend, who vanished two years ago and has now come right to his doorstep. “Duan Feng, you haven't done so well these past two years, have you? You're just a low-ranking assistant officer.” “No wonder you'll never amount to anything.” “Don't let me see you again.” “Besides, someone as low-class as you will never get near the circles we upper-class people move in.” Instead of getting angry, Duan Feng is delighted. With the System's help, he discovers that his ex-girlfriend is part of a honey-trap gang and a murderer wanted for crimes across several provinces. What better chance to earn merit? From then on, with the System's help, Duan Feng solves cases as if aided by a divine hand. He makes one round on patrol and arrests a major theft ring. He casually fishes by the river and cracks a murder-and-body-dumping case. Police Chief: Where's Duan Feng? I want to meet him in person. Forensic Expert: He's the most impressive person I've ever met. I want to be his apprentice. Task Force: You solved a ten-year-old cold case with just one look?
