Gao Yang was gasping for breath, an instinctive response in a desperate situation, but at the moment he pulled the trigger, Gao Yang could hold his breath until after firing the shot, so his rapid breathing did not affect his shooting accuracy.
Seeing someone trying to pick up an RPG that had fallen to the ground, Gao Yang did not shoot. The distance was too great, and hitting a moving target was too difficult. He simply aimed at the Rebel Army soldier trying to pick up the RPG and only took the shot when the soldier had picked up the RPG, rested it on his shoulder, and knelt on one knee to aim.
After the gunshot, although the RPG was picked up, it could not be fired.
After shooting the enemy, Gao Yang immediately resumed gasping for breath and shouted, "Test Tube! Take care of yourself first."
