[Espionage + crime-solving + master detective + deduction + counterintelligence + War of Resistance against Japan + no female lead + iron-blooded]
From the start, police detective Su Hao is reborn in 1936. The good news: his uncle is a chief inspector. The bad news: he’s thrown straight into a life-or-death situation. Sound about right?
But there’s more good news: he has a cheat, the ability to rewind and review crime scenes. Using this power and his past-life experience in criminal investigations, Su Hao rises from a low-ranking Chinese detective to a plainclothes officer, and eventually becomes the most renowned master detective in the French Concession.
But... what do you mean I’m so capable that you want me to secretly join the Military Intelligence Department and serve the party and nation? Wait! Is it a crime to be good at solving cases?!
