Three hundred years, for the world itself, is not a very long time.
Yet for the creatures within the world, it could be considered an eternity.
Especially for ordinary humans, three centuries probably span several generations.
In Tianqing World, these three hundred years were indeed marked by earth-shaking changes.
Firstly, there was the widespread adoption of the Martial Tao Cultivation System; the original cultivation systems of Tianqing World had high barriers to entry, and the major powers colluded to maintain a de facto monopoly.
This meant that people at the bottom had no way to advance, living out their entire lives without access to the higher paths.
It was just three or four hundred years ago that the Martial Tao Cultivation System began to spread.
Compared to the original cultivation systems of the world, the threshold to start practicing the Martial Tao was so low it was almost laughable.
As long as one was human, they were qualified to practice the Martial Tao.
