Zhang Qingfeng came to the world of Liangjian and engaged in industry, focusing on national defense. From a battalion commander of the defeated Jinsui Army, he became a guerrilla captain of the Eighth Route Army. And finally, as commander of an independent column. In just a few months, we had everything from mortars to heavy machine guns. Tens of thousands of soldiers, each armed with a semi-automatic rifle, ransacked Daqing warehouses, wiped out the Gangcun Brigade, ambushed the Sato Regiment, and even crippled the Japanese 36th Division. Established the first flying regiment of the 129th Division, produced the first tank armored division, built the first power plant, etc. This is because Zhang Qingfeng has a commander system. As long as he commands the battle to destroy the enemy, he can obtain various system rewards. In this way, a steel-like army emerged from the sky with endless artillery fire, fighting in the north and south to defend the territory.
