War of Resistance: I, Li Yunlong, Become a Military Weapons Expert

A passionate, upstanding young man from the 21st century transmigrates into the world of "Drawing Sword" and becomes Li Yunlong, commander of the New First Regiment. The Sakamoto Regiment has yet to attack Cangyun Ridge, the Battle of Ping'an County has not yet begun, and Li Yunlong binds himself to a Military Industry Expert System.

"Chief, I recommend appointing Li Yunlong as the Border Region Arsenal's outside chief expert!"

"Chief, Li Yunlong has developed a new type of grenade, modified a grenade launcher, and modeled a general-purpose machine gun after the German design!"

"Chief, grain production in the base area where Li Yunlong is stationed has doubled..."

This was an era of passion and tragedy.
