The Anti-Japanese System Is Awesome

Wu Hai, a special soldier of the border defense, was discharged from the army due to injury in the service and returned to his hometown to recuperate. By chance, I bound the system and traveled to the parallel world during the Anti-Japanese War. From then on, I started another life, fighting Japanese, killing traitors and removing spies. I started to develop my own power single-handedly. I relied on the system to sweep away the enemies and write my own legend.
