At that time, it might be possible to explain a large number of biological weapons as a new tribe coming from the North Wilderness—this tribe has always lived in the impoverished and barren depths of the North Wilderness, rarely interacting with the outside world, so they are not known to people. The members of this tribe are taciturn, not good at communication, but strong and loyal, extremely excellent warriors, and extremely excellent subjects.
If nothing unexpected happens, these tribespeople will continue to live in the North Wilderness. But recently, due to the worsening environment in the North Wilderness, food production cannot sustain the tribe's continuation. So these tribespeople, batch by batch, leave the North Wilderness and come to Shalin, the place closest to the North Wilderness, becoming new subjects.
