In the third year of the Dazong winter, Lin Feng, a border garrison soldier, was kicked to death by his corporal. When he opened his eyes again, he had changed to a modern soul. As an inheritor of ancient martial arts in his past life, situated in the bitter cold of the Lingdouzi beacon tower, facing fierce Tiezhen Tatars and treacherous colleagues, he revealed astonishing talent. Using simple bows and arrows, he successively sniped enemy troops, winning reward silver and grain; he personally built traps and fortifications, defeating the strong with the weak to counter-kill bronze-armored Tatars. An isolated army in the snowfield, treacherous human relationships, step by step he gave tit for tat, stepping from the lowest-level soldier onto the path of rise. The iron-blooded excitement of cold weapon clashes, the passionate heroism of a grassroots counter-attack—only amidst beacon fires and slaughter knives can a new world be fought for.
