Taking Harbin as the stage, the protagonist operates multiple networks under the public identity of "Deputy Chief of the Police Department" and uses modern espionage theories (such as the real-time reconstruction of "dead mailboxes", "traffic lines" and "shadow liaisons") to engage in intellectual games with the Japanese and puppets. The core anti-routine point is that the protagonist's golden finger is not a system or a superpower, but an extraordinary "intelligence topology intuition" - he can construct a complete enemy action network topology in his mind by analyzing fragmented information and predict every step of the opponent.
