Jianshang Li Yunlong

Li Yunlong is transferred to handle logistics, but the warehouse contains only moldy millet and duds—while the soldiers at the front are close to starving.

After all conventional methods hit a wall, he gets angry: "Doing logistics behind enemy lines means I can't act like a shopkeeper. I have to act like a bandit!"

He secretly forms a shadow unit, the Black Wind Squad—raiding Japanese warehouses, reselling Japanese goods, negotiating profit shares with puppet troops, and taking back ten times what shady merchants swindle from him.

He turns logistics into a business, turns the puppet troops into A, B, and C tier "packages," and turns the Japanese supply lines into his own procurement channels.

The headquarters never acknowledges this unit, but everyone at the front knows one thing: "If you're short on something, find Li Yunlong. His Japanese warehouse has everything."

From the Taihang Mountains to Huaihai, from the War of Resistance to the Korean War, this shadow force that never officially "exists" still uses rifles and ledgers to hold up half the battlefield.
