The same was not true for Hungry Pain. The difficulty of the technique was grade-six. It took immense perseverance, but any Martial Squire had the ability to master the technique fully. Meaning it could instantly boost all future Martial Squires by forty-fifty percent compared to the previous generation.
That was massive for a single technique.
Rui was willing to share it with the Martial Union even as a Martial Squire because he had a greater amount of trust in the organization. He understood it well enough that it was, by design, remarkably meritocratic. The Hungry Pain technique was just valuable enough that it would massively increase his value to the organization, but not to the degree that it would be harmful to him.
This was in sharp contrast to accelerating the breakthrough rates of Martial Apprentices. Rui did not trust anybody with that information. It was beyond revolutionary.
