While it definitely took more energy and time to remove the stubborn specks, the same basic rule was still maintained, progress was being made regardless!
It had only taken two weeks to achieve a basic channel clearing, but clearing the imperfections took more than a day per channel. Even when Leo exploded into a new wind, his spirit would be soon worn down! It was a never-ending cycle!
'Soon…'
In order to focus on the target without any distractions, Leo silently chanted that success was near, every channel that was completely cleared made the work on the next one slightly easier. It wasn't much, but it was better than nothing.
If it was the same Leo who was yearning to wield any sort of supernatural power at the start of his Sword Breathing practice, he might have already given up to the charm of operating his first Energy Circulation and lighting up his Dantian, but the current Leo was beyond that state!
