Blitzing around the region, Lex found that it was extremely large and even with his speed would take him a while to get around. While doing so, he sought out any cultivator related to the Blood Sword Group and struck them down without remorse.
Their numbers were in the thousands, while it became clear to Lex that they had complete control over the region, while he was also impressed by the size and prosperity of the region.
It wasn't because of the Blood Sword Group, as the region would be much better off without them doing as they pleased and forcing the citizens to pay taxes to them, but because of the density of energy.
The closer they got to the centre of the Lower Plains, the denser the energy became, while the more resources and opportunities could be found. The land was very fertile and could also rapidly grow plants, while the people were naturally strong and healthy, so lived extended lifetimes.
