Shen Yan, the chief psychological analyst of the National Security Bureau, transformed into a humble traitor translator during the Anti-Japanese War. In this turbulent "Sea City", he has become the most despicable pawn in the eyes of all forces. However, they did not know that they were facing a "cognitive level" genius who could predict and predict again. Use psychology to trick spies, use financial warfare to plunder enemy countries, and use propaganda warfare to subvert people's hearts. This is not an assassination, but a heart-breaking one. When everyone was looking for the chess player behind the scenes, Shen Yan pushed up his gold-rimmed glasses, smiled, and turned the whole world into his chessboard.
