Undercurrent: 1934

Jiang Yuan, a modern strategic analyst, traveled back to 1934. This is a story about a time traveler struggling, choosing and fighting in the torrent of history with solid professional abilities (not superpowers). He used the intelligence battlefield to change his personal destiny while exerting a small but precise influence on the historical process at critical moments, such as protecting personnel, delivering early warnings, sabotaging and plundering, and eventually grew from an excellent officer to a secret warrior who cared about his family and country.
