On the surface is a turbulent financial battlefield, while in the deep waters is an extremely dangerous spy situation. Ji Han, on the surface, is just an inconspicuous financial analyst in a bustling city. He is diligent and taciturn. He is an "honest person" in the eyes of his colleagues and a "useful tool" in the hands of his boss. However, when a cold token was handed to him, he realized that he had become a pawn to replace the victim "Raven" in a dangerous chess game that had already begun.
During the day, he has to endure the strife and calculations in the workplace, converging on boring reports and capital games; in the middle of the night, he must transform into a hunting shadow walking on the edge of a knife, relying on his top business sense and battlefield instincts to survive in the traps and transactions of intelligence organizations from various countries. His weapons are not bullets, but a series of Excel formulas, industry slang carefully buried in research reports, and weird K-line charts that foreshadow assassinations.
When a grand cross-border merger is finalized and champagne is poured out, only he knows that a cold button on the CEO's suit is enough to turn the entire crowd's clothes into powder. "Ji Han, go pour champagne for the distinguished guests." The president said lightly, but his finger heading towards the destroy button had already tapped the cork to signal retreat - "Above the Undercurrent", a war without gunpowder, how a transparent social animal works step by step, stirring up unfathomable undercurrents amidst the strife of giants from all sides.
