Eva would freeze as the sound of gunshots, having come up for air, the sudden bangs of the gun firing each individual bullet with her great hearing, was something new, a new sound she had yet to hear, it would scare her as she stopped swimming towards the noises and think about what to do, she was hungry yes, but was she hungry enough to get hurt? also what made those bang noises? and should she continue? all the questions confused her and muddled her mind, she was not much of a thinker, but her instincts told her to be wary and move on, listening to them, she opened her mouth and took in a massive gulp of air, her lungs expanding to their limit as she then dove under water and vanished from sight, staying hidden under water, but moving slowly in the same direction, using the river floor to move as she pulled herself along, both swimming with her feet and grabbing rocks sitting on the river floor, to pull herself forward, as well as swallowing a few large sized rocks which would sit inside her stomach and help weigh her down enough to stay submerged till the next breath.
