My second kick catches him square in the solar plexus. He doubles over gasping for air. I pull the flexible mask attached to the small air bottle on my belt free and stand over him. I open the bottle and force the mask over his mouth. He can't stop himself from breathing in the carbon monoxide. He struggles get weaker with each breath until he stops moving. I hold the mask over his face until his chest stops as well.
The smoke is getting thicker. I look around and I'm surrounded. Why aren't they gasping and choking on the smoke? I wonder before the first one lunges at me.
