When agricultural civilization reaches a certain stage, it will gradually advance from handicraft to an industrial civilization dominated by machinery.
During this period, automation equipment such as looms, internal combustion engines, and industrial lathes, which greatly save manpower, will inevitably emerge.
However, this rule does not necessarily apply to the Skeletons.
Because Skeletons have little demand for agriculture, and even the domestication of Bone Beasts is merely for better reproduction.
Therefore, it wasn't until Virtuous King Gu Sheng established the Hundred Races Alliance that the Skeletons truly broke away from the primitive civilization stage and entered a rather peculiar period of agricultural civilization.
During this phase, the Skeletons experienced the rule of three distinctly different leaders: the Virtuous King, the Tyrant, and the Prophet.
Eventually, a special governing class that suited the Skeletons' race and intrinsic needs took shape—Zhiku.
