Reyuan Dong didn't move a muscle, and Gao Yang's shot missed its mark.
Even if a mere twig stood in the path of a bullet, the slightest touch would be enough to alter the bullet's trajectory. A miss is as good as a mile, and a bullet with a changed path would certainly not hit the enemy.
At only a little over sixty meters, Gao Yang thought the enemy could hear the gunshot, but after he fired once and Reyuan Dong still didn't budge, he quickly fired a second shot.
Following the sound of the gunfire, the target remained still, so Gao Yang took a third shot.
Gao Yang fired rapidly, and he would continue as long as the target didn't move.
Gao Yang believed there were twigs in the bullet's path but nothing too large; a big twig would be visible through the night vision device, while smaller ones would be broken or knocked aside by the bullets. This meant that if he could maintain a consistent trajectory, his bullet would eventually break through the obstacles and hit the target.
