Troop Buildings at the first tier correspond to Common One-Star Troops, those at the second tier correspond to Common Three-Star Troops, and those at the third tier correspond to Rare One-Star Troops.
The highest seemed to be the seventh tier.
However, there were no records of seventh-tier buildings. Even in Dragon Court Land, where several great nations gathered troops and fought fiercely for control, there were only sixth-tier Dragon Nests.
In a sixth-tier territory, basic recruitment alone could produce Excellent Three-Star Troops, with a chance of critically producing Epic Lifeforms.
Moreover, such sixth-tier Troop Buildings could recruit a batch at regular intervals. No wonder every great nation fought with all its might to seize them.
This already concerned the foundation of a nation.

Precisely because Skeleton Graveyard existed, he did not need to invest Soul Sand, and batch after batch of Little Skeletons had gradually risen to Levels 6, 7, and 8. The amount of Soul Sand this saved was no small figure.
The increase in cultivation speed was also extremely significant, nearly doubling it.
By comparison, the most basic skeleton recruitment function seemed thoroughly ordinary.
