Xiao Yuan opened his eyes. In front of him was the hole-ridden west wall of Sihang Warehouse, and behind him were the neon lights of the concession on the other side of the Suzhou River. The Japanese planes shot at the scalp, and the corpses of the entire battalion of officers and soldiers were covered with barbed wire - he became the supreme commander of this lone army. The moment the system was activated, a grenade blasted through the outer wall of the command post: "The casualty ratio between ourselves and the enemy is 100:1, triggering desperate critical strike authority." Xiao Yuan crawled out from the pile of dead people and picked up the red rifle. His hands were shaking like chaff, but the corners of his mouth were grinning to the base of his ears. Because he could see, there was a line of blood-red numbers floating above each devil's head - kill reward: permanent attribute +0.1. Street fighting? He has a modern special operations manual. Suppressive fire? He can make improvised incendiary bombs with his hands. When the national army was completely defeated and everyone thought that Sihang Warehouse was certain to die, Xiao Yuan was writing the last stroke of bloody grass on the wall riddled with holes: "Those who invade our mountains and rivers will collapse every time they see one!"
