Chapter 519: Doubt VS Conscience

David might be one of the current strongest humans on Earth, but he knew full well that only applied to humans. The creature stomping its way toward them by far surpassed what they should fight in terms of power.

"I think we should back off and come back," he declared, sweat pearling off his forehead.

Alex looked at him, confused. He had yet to see David ever back down from a fight.

"Since when do you back away? Weren't you the future of humanity? How can you see all these monsters and think about running away?"

His voice contained a bit of loathing. That day, a small part of the respect Alex had for David's hard-ass attitude disappeared.

"If we die here, how are we going to keep fighting for humanity, huh? Use your empty head a bit, Alex. This foe is far out of our reach. We should retreat and come back when we are stronger. Or get help from well-armed people."
