Alex moved quickly; he initially believed that the girls would be on the third floor, from the sound of his hearing, but he never thought that because his body had improved so far, the sounds were much higher, closer to the top floor, rushing up the stairs his feel like a gazelle rushing through an open field.
The newly found power inside his body felt terrific, causing his steps to be long, almost bouncing like a rubber ball each time his shoes touched the ground, light taps echoing in the eerie and deserted hallways as he made sure to check each floor, just in case there was something the girls missed, only finding the half-destroyed corpses of regular zombies with spear and arrow wounds.
'These girls... Do they want a reward that badly?' He looked upward, lost in thought, with a wicked smile on his lips, heading towards the fourth-floor staircase, his snowy hair dancing in the air behind him.
