Jayce had a few clues about the power of Inner Qi and martial arts, however he was no expert. There was also very little chance he would be able to find any books that would outline ways to grow stronger.
All he had to go on was the knowledge that this power was likely something that Human's had access to in the past. His theory was mainly based off the theory of Martial Arts and some things that Rubick had said in passing.
While this wasn't a great basis for a theory and there were many variables and inconsistencies, it was better than no direction at all.
So Jayce put the word out, asking for anyone who had knowledge about ancient Chinese Medicine or Martial Arts. It had taken two months, but he had finally found one, right after reaching a bottleneck as well.
A woman in her late 30's visited him one afternoon. She was rather short and looked like she had worked with her hands most of her life.
