Police Commissioner: "You want revenge?"
Male protagonist: "I was insulted by my boss and treated as a bumpkin by my colleagues. How could I not want to take revenge?"
Director: "Good comrade, I have a few simple cases here. Come and follow me."
The male protagonist was shocked: "Senior! How can this be done?"
Director: "Hacker intrusion, AI fraud, virtual currency money laundering, dark web smuggling, Sky Eye system failure... Are all things that other police officers are unwilling to touch."
Male protagonist: "..."
The director smiled: "Aren't you known as the 'Master of Local Tracking'? Since the high technology has failed, you will take the blame and use your local methods."
The male protagonist frowned: "There are so many serious and difficult cases, I'm afraid..."
The director laughed: "Afraid you can't solve the case and will be ridiculed by your colleagues?"
Male protagonist: "No, I'm afraid that the murderer will kneel down and call me daddy when he sees me!"
Director: "..., If you can solve the case, I will also call you."
