With secure dwellings and clothing to withstand harsh weather, humanity's capacity for survival was finally laid bare.
In merely a few hundred years, humanity's footsteps had spread to nearly every corner between the two great mountains.
Every tribe was guarded by one or two Great Shamans, with dozens or even hundreds of shamans leading thousands upon thousands of tribespeople.
From the sky, one could see tribes scattered across the land between the two mountain ranges.
They had squeezed the living space of other creatures to the utmost limit.
Only certain highly fertile races had been left behind by humanity, to serve as provisions for the hunt at any time.
Yet as humanity grew ever more numerous, so too did the shamans born among them.
Originally, this should have been a good thing for humanity. After all, the more strong individuals there were, the better.
But in truth, the growing number of shamans had brought certain changes to humanity's condition.
With Great Shamans, ordinary tribespeople could live peacefully beneath the shamans' protection.
But gradually, they seemed to have lost their value.
Humanity still survived by gathering wild fruits and hunting exotic beasts, and the powerful shamans were the main force behind both of these activities.
After all, in this savage world, some ordinary humans found even plants difficult to deal with.
They simply could not gather enough fruit amid vines that filled the sky, tangled tree roots, and poisonous miasma that killed without a trace.
