The protagonist Gu Changfeng possesses the "Battlefield Skynet" gold finger, which is a passive skill that allows his brain to physically resonate with all radio frequencies in the current combat area. In his perception, radio stations from different units will appear in his mind as light spots of different colors and brightness. The enemy tower is dazzling red, the friendly forces are dim blue, and the silent ones are gray dots. He can not only hear, but also control the identification of friend or foe and the transmission of information by imitating, interfering or even covering the fluctuation frequency of these "light spots". But the price is extremely high. This ability is deeply bound to his auditory nerve. Every time he uses it, his own eardrums will withstand a gunshot-like shock.
