Daoist Soldiers were simply beyond the ability of small sects or ordinary aristocratic clans to train.
Small Thousand Worlds lacked the resources. Medium Thousand Worlds had enough, but were unwilling to devote too much to Daoist Soldiers.
Only Great Thousand Worlds possessed sufficient resources, manpower, material wealth, and accumulated reserves to support the training of Daoist Soldiers.
Training a force of Daoist Soldiers, even the most basic low-grade ones, was never the work of a single day.
It demanded vast supplies of pills and blood food, countless spirit stones, thousands upon thousands of magical artifacts, and ten or even a hundred times as much manpower.
Not everyone was qualified to be trained into a Daoist Soldier. The low-grade Daoist Soldiers of ordinary powers might possess only Qi Refining or Foundation Establishment cultivation, but throughout All Heavens and Myriad Worlds, even those two lowest and most populous of the nine cultivation realms were beyond the reach of how many mortals?
Only a Pure Yang Sacred Land that controlled a Great Thousand World, commanded the resources of countless Medium and Small Thousand Worlds, and enjoyed the support of boundless manpower and material wealth could raise vast numbers of Daoist Soldiers.
Take the Tianhe Dao Sect, for example. Its low-grade Daoist Soldiers possessed Golden Core cultivation, while the commanders of their battle squares were great cultivators in the Nascent Soul and Spirit Transformation realms. A single ten-thousand-strong square formed by these cultivators could level a kingdom and sweep across an entire region.
Even low-grade Daoist Soldiers were an important force for keeping Small and Medium Thousand Worlds under control.
Yet in a clash between Dao Sects, low-grade Daoist Soldiers existed merely to expend the enemy's strength. They were cannon fodder.
Training four million low-grade Daoist Soldiers was harder than raising four million Golden
