'Fuckk! It feels like the energy is eating away at my existence! No! I gotta focus! This is just a trial I have to overcome! I got this!'
Zion didn't think he would have to use his chakras already. While they would normally be filled with energy, he made sure to keep them empty in case there was another energy that existed, so he could use it. Never did he think it would be demonic energy.
In any case, he had to accept it.
He guided the infernal energy through his body, forcing it into his chakras instead of cores and dantians.
It was painful.
The infernal energy instinctively wanted to eat his other energies, so keeping it in his chakras was a difficult task at first, but like a magnet, it eventually latched onto his root chakra. After assimilating with it, the energy shot up, moving to the next chakra, then the next, then the next, until finally, all seven of his chakras were filled with infernal energy.
