章 214: Chapter 168: City of the Old Days_2

The process required pioneers to survey the terrain, assess the risks, kill all the desolate beasts in a region, then temporarily enclose it, and finally clear out the beast eggs.

They had to clear the land hundreds of square meters at a time and set various observation periods for these lands, based on the hatching time of the desolate beast eggs.

Some desolate beasts might hatch in a few days, while others might take several years. The observation periods were set to allow those eggs buried too deep to be detected to hatch first, then be killed, to prevent any from slipping through the net.

If no desolate beast appeared on this land within two years, it could basically be considered a safe area, and then be integrated into the territory, with additional defensive measures set up around this land.
