True origin aura was actually an aura formed based on pure true origin using the thick qi in his body after he mastered Tendon Changing Classic and cleared his eight extra meridians.
However, since Tendon Changing Classic could widen the breadth of his meridian system, the true origin he released was several times the amount of a normal person, which was why it could create an aura of such a scale.
The greatest effect of this sort of true origin aura was to exclude all foreign objects.
True origin had an astonishing rejection force toward foreign objects and all other things that did not fuse with it. Once any sort of external force tried to mix in, it would immediately look as if it fell into a pot of boiling oil, and it would evaporate.
One part of the force in the Myth Realm martial artist's attack was instantly weakened.
Twenty percent of his damage was reduced.
