New recruit Han Zheng ranks last in his company for physical fitness, earning the nickname “Walking Target” from his fellow soldiers. Then, during a mock combat exercise, he is cornered and rips the barrel off a main battle tank with his bare hands, stunning everyone. Special forces instructor Tie Hu sets his sights on him, while tactical genius Shen Ruochuan takes an interest too. But Han Zheng's incredible strength is no accident: it is tied to a classified human-enhancement experiment and a border squad that was silenced. As Shen Ruochuan, Cheng Lan, and others join the fray, Han Zheng discovers that he has become entangled in an international conspiracy. The fragments of the tank barrel in his hands hold the key to uncovering the truth. From a mocked rookie to an “armor-breaking soldier” capable of tearing through armor, Han Zheng and Shen Ruochuan bring out the best in each other on the brink of death, and their every move has already begun to rewrite the rules of modern warfare.
