"What?" Haris frowned.
"You heard me. As long as you keep using the upgraded weapon to kill infected, you'll gradually become stronger."
Bong-gu immediately looked at his shotgun. "Wait. You're telling me this thing can make me stronger?"
"Not the weapon itself," Jaxon explained. "The upgrade does."
He looked around the room. "Every weapon has a different effect. My DMR increases my Strength. Bong-gu's shotgun increases Vitality. Natasha's pistols increase Speed, while Na-rin's weapon increases Agility."
Bong-gu scratched his head. "Hold on. What exactly is Vitality?"
"Recovery, pain tolerance, and how well your body handles injuries."
Bong-gu's eyes immediately lit up. "Damn. That's awesome."
"You'll need thousands of kills before the difference becomes huge," Jaxon added. "But if you keep using the weapon, the growth will never stop."
"So that's why you became so strong," Elena said, looking at him with a new understanding.
Jaxon simply nodded.
