Espionage: What? I Transmigrated Into a Key Member of the Special Higher Police

[Undercover + Realistic + Minor System Elements + Black-Market Trading] Qin Chang’an transmigrates to the Republican era and, through a twist of fate, infiltrates the Special Higher Police, becoming one of its key members. Qin Chang’an moves through the night, and must do more than conceal his identity. He faces one test after another from the Special Higher Police, and sometimes even has to survive assassination attempts by his own side. Qin Chang’an can only use his position to steadily build his influence, steal intelligence, and even establish his own business empire. He has many identities: the Special Higher Police’s executioner, the Military Statistics Bureau’s ace in Shanghai, an elite member of the underground party, and a business genius and stock-market king across the ocean.
