The Primordial Path was something Lin Mu had set upon unknowingly.
From what he had learned from Senior Xukong it was one of the oldest paths of cultivation which demanded on to forge their own way and finding their own technique. No single person would have the same technique, but an entirely new legacy could be forged from the followers of the primordial path.
The Primordial path was old and so were its followers. Many had given up on it and some even considered it obsolete now. It brought few benefits for the cultivators in the short term and left a lot to be desired.
But Xukong had told Lin Mu that the Primordial path had its own benefits that no other technique could grant him. It would allow him to be unhindered and not face the same kind of cultivation bottleneck that others had.
The only thing he would be limited by is his own comprehension since for the primordial path, even talent didn't matter.
