On the night of September 18, 1931, Shenyang Beida Camp. Lin Ye woke up to deafening artillery fire and chaos, and a cold mechanical voice sounded in his head at the same time: "The iron-blooded soul system is activated. Initial mission: Survive, and launch the first effective counterattack against the invaders within 24 hours."
He looked at the old Liao-made rifle in his hand, and then at the outline of Japanese armored vehicles in the distance, his eyes turning from confused to sharp in an instant. "Counterattack?" He pulled the bolt of his gun and growled to the frightened recruits beside him: "If you want to survive, follow my example. Tonight, the hunting begins."
