One shot, two shots, three shots.
Gao Yi wielded a handgun, but he didn't employ the Mozambique technique; all three shots went for the head.
Hitting the torso would undoubtedly be ineffective because handgun bullets simply can't penetrate heavy-duty bulletproof plates.
If using a handgun, the only option was to aim for the head, but the target also had a helmet; ordinary handgun rounds could not penetrate a bullet-proof helmet since the basic requirement for military helmets is to resist direct hits from 9mm parabellum rounds and shrapnel from explosions.
So, Gao Yi aimed for the face.
But the enemy's face was protected by a transparent bullet-proof mask.
The first shot struck the side of the helmet, failing to penetrate.
With the second shot, Gao Yi targeted the mask, leaving a mark on the enemy's mask, but his bullets, no ordinary rounds, were still unable to penetrate.
