A top student at the National Defense University is hit by a car while saving someone. When he opens his eyes, he has become an overseas student in 1937. Trapped in occupied territory and facing the Japanese invasion, is he really unarmed? No. His mind holds decades’ worth of future military technology, tactics, and strategy. From forming guerrilla units to designing improvised weapons and predicting the enemy’s every move, he leads his brothers in carving a path to survival through the heaps of the dead. While others wait for reinforcements, he waits for the right moment. While others flee for their lives, he lays his plans.
