At the end of October 1937, the cold wind was biting in eastern Shanxi. Su Dingfang died while performing his mission, and when he opened his eyes, he turned out to be the commander of the Third Battalion of the Eighth Route Army's Cadre Regiment. His boss was the famous reckless man Kong Jie. Just one month later, the sign-in system was finally activated. The first time he signed in, he bumped into a Jinsui Army position that had just been attacked by Japanese air raids. Under the corpses on the ground, hundreds of grenades, a dozen box guns, two light machine guns, and thousands of bullets lay there quietly, unclaimed. Su Dingfang led the third battalion to bury the martyrs and collect the equipment. The team that was not even equipped with large blades was transformed overnight. But before he could digest this "windfall", an urgent order came from the brigade headquarters: Immediately go to Chaiyu Town to set up front-line defenses. The system's second check-in location, Paijialing, happened to be within the defense zone. What will be waiting for him this time? Take the enemy's gun and fight the devil's war. Su Dingfang and his brothers from the Third Battalion wanted to make a mark in the land of eastern Shanxi.
