Defending Sihang Warehouse: Forging a German-Equipped Division

National Defense student Li Jianghe activates a military expansion system on the brutal battlefield of Shanghai. Through this system, he can redeem various infantry squads using merit points earned in combat, ranging from standard German-equipped units to Soviet and specialized German formations. As his rank increases, the system unlocks even greater firepower, allowing him to directly acquire artillery batteries, tank battalions, and air support. Originally tasked with holding the line as an isolated force at Sihang Warehouse, Li Jianghe defies expectations as his troops multiply and strengthen with every engagement, transforming a desperate last stand into an unstoppable military force on the front lines.
