My Years as a Dandy in the Juntong

[Spy warfare + high intelligence + rooting out Japanese spies + no System]

If you haven't read spy fiction, don't click in, because you won't understand it.

A special forces soldier is reborn with the same soul (what does that mean?) in the Republican era. The Military Statistics Bureau's Seventh Brother opens a bank and establishes a secret international merchant association. The Skull and Bones, the great families, and all the rest can step aside: the Flower-Planting Nation is the best at doing business! He brings the K Agency to ruin. He's the wealthy, playboy schemer known as Seventh Brother of the Military Statistics Bureau. He leaves Japanese spies nowhere to hide, funnels all the corrupt money into his own pockets, and has the heads of both the Military Statistics Bureau and the Central Bureau revolving around him. He personally sends Boss Dai onto a plane with no return flight. Ye Haiwen gives his enemies headaches and his own side reasons to cheer. He spends fifty years undercover in enemy territory, controls half a century of the underworld, and sets the whole underground world in turmoil.
