Lin Che joined the army at the age of 19. Her music bag was more eye-catching than a rifle, and she was treated as a joke by the whole company on the first day. But at night when he was at the bottom of the three-kilometer range, he could close his eyes and hear a late shot of a gun two kilometers away - "absolute sound". It was not a metaphor, it was a golden finger. In Chapter 30 of the Recruit Company, he crossed five kilometers by breathing to the rhythm of his breath, and led the class through a simulated minefield by listening to the wind. He went from being a joke to becoming the most irreplaceable ear of the company. The codename "Metronome" was awarded by the Hunter School finalist.
