The North American Grey Wolf Pack, the Terrifying Spider Swarm, the Poisonous Scorpion Swarm, and others all stubbornly survived on the North American Continent, each with the strength of first-class forces.
Especially the Poisonous Scorpion Swarm,
during the apocalyptic catastrophe and the ground cleansing by nuclear weapons, managed to hide in the deepest part of the underground, suffering not too significant losses.
They even evolved tough and unparalleled exoskeletons to survive the intense nuclear radiation!
Today, there are over nine million of the Poisonous Scorpion Swarm, where the shell of any scorpion can only be broken by King Level beings.
As for those above the King Level, their defensive power far surpasses those of the same tier.
Moreover, the most important point is that the Poisonous Scorpion Swarm is the only group in the whole North American region that has established its own fortune!
Such first-class forces pose a threat even to the monstrous forces.
