As Jenny trekked through the vast mountains and valleys of the fifteenth floor, her erratic breathing continued to worsen. Her face was flushed, while a certain, overpowering sense of fatigue settled in.
Sweat trickled down her skin, but was instantly frozen by the polar gusts that continuously assaulted her from all directions. Her eyelids drooped, and the urge to succumb arose in her chest.
Frost settled on eyelids, the only part of her body yet to be covered by clothing. A constant flow of mana prevented most colds from affecting Jenny, but such harsh winds could not be resisted through regular means.
"Flame," Jenny barely managed to utter, combusting the nearby oxygen to create a tiny spark of flame that levitated atop her palm. However, incapable of managing it, Jenny accidentally allowed the flame to be extinguished.
She tried yet again and was forced to expend a higher quantity of mana.
