You Call Me an Old Republican-Era Cop? I'm the King of Criminal Investigation!

Sun Hang, born into a family of police officers, transmigrates back to the year 1950.

Because of his identity as a former police officer under the Republic of China, he is sent home to lie flat.

But after the case at the Kyoto Tram Factory, he is temporarily brought in to do odd jobs.

Team Captain: "Director, Sun Hang was a black dog under the Republic of China, an old cop. What does he know about criminal investigations?"

"We can't use someone like him."

The entire criminal investigation team looks at Sun Hang askance, dislikes him, and ostracizes him.

That is, until Sun Hang analyzes the case: "These three marks were left by a device called a flying tiger claw."

"See those footprints on the ground? They were left by first-generation rebound shoes, so there was a third person at the scene."

"You people have some pretty professional equipment, but the work you did was really sloppy..."

Sun Hang's case analysis shocks everyone.

Following his analysis, they quickly identify the enemy agents at the tram factory.

Director: "From now on, Sun Hang is one of our comrades. Anyone who calls him a black dog will get a bullet from me."
