One Punch

"These Cores really are some good stuff. I'm impressed Ninu." Darcel sincerely praised. He had to fathom if left to their own training, it would take several weeks to a month to advance to another Heavenly level. 

Of course, this didn't have to do anything with either Darcel, Aniela, or Masami's Qi comprehension. Each of them can effortlessly control Heavenly Qi at this point. Their comprehension of Heavenly Qi complex properties reached terrifying degrees, allowing their soul force to tightly grasp the Qi energy. 

No, the only problem came in the form of their own Heavenly Core absorption. 

Their Heavenly Cores may be hundreds of times denser than numerous other geniuses, but this caused their need for Heavenly Qi to be greater than other geniuses.
