Anti-Japanese Bandit Army

This article tells the story of a certain unit of the Northeastern Army in Shuo County, Shanxi Province. Most of them were killed in the fight against Xiaori. One of his troops, Chen Xianyi, was knocked unconscious by a stray bullet while covering the retreat of the people. After waking up, he witnessed the massacre of the city by Xiaori. He obtained the system out of grief and anger, and later joined the Qing Dynasty. Fengzhai successfully formed a coalition of bandits from the Nine Mountains and Eighteen Villages, and was later organized by the government and awarded the title of "Hu Ben". They formed an army and swept through Shanxi Province. They marched east to North China, south to Jiangnan, and north to Northeast China, killing wildly in the small days of China. This is a fun article, and that's it. In order to rationalize the plot, I had to add a system, mainly at the beginning, and gradually faded away later.
