College Military Training: Firing a Rocket Launcher at Japanese Planes

Lin Yu is reborn, back to when he was eighteen and just starting military training at university. He also gets bound to a Super Military Industry System. On the day of live-fire target practice, Lin Yu turns an ordinary Type 95 rifle into a rocket launcher. He was only planning to shoot at the targets, but then, would you believe it, a Japanese plane flew right over his head. How could he let that slide?!

Lin Yu quietly hoists his gun and shoots the plane down!
