When "voice talent" meets "espionage work", it subverts the traditional methods of agents relying on violence or beauty. The protagonist Shen Hansheng relied on auditory hyperamnesia and top-level logical reasoning to enter the battlefield from deciphering the Japanese army's voice-coded encrypted messages. But the enemy is not a fool. The Japanese also have top acoustic experts and anti-tracking tactics. What's even more deadly is that a high-level traitor within the national government code-named "Ghost" always seems to be able to take advantage of intelligence gaps to make every action of the protagonist step into a trap. This is an atypical agent story that uses ears to fight and logic to solve problems. The core conflict is: how to use the only trustworthy "ear" to uncover all hidden enemies in a system full of moles.
