Ironclad Army in the War of Resistance, Starting with a Guerrilla Unit

Zhou Weiguo, who came from the modern era, became a company commander under Li Yunlong. After making a mistake, he was demoted to the guerrilla forces. He defended his homeland, established the first arsenal, and personally led an iron tide south to fight 100,000 Japanese troops. He reorganized recruits, modernized national defense, and built up the country's strength. From then on, he swept across the Central Plains and established an invincible army with an unyielding backbone.
