Fixten
Couldn't Kai theoretically use the power of oscillation to atomize literally anything? He just has to find the right series of frequencies and contain them in a specific area. Also just speculation but maybe he could reinforce his body with magic and oscillate himself at the proper frequency of air so he can phase though things like the flash.
I would love to keep reading this story, but I just can't. The story has a lot of potential, but could use a better author. There are just too many grammatical errors, abd the author seems to have this compulsive need to over explain every irrelevant detail while failing to accurately describe important plot scenes. The author also keeps forgetting the difference between past and present tense as well as whether it was a male character he was describing or a female (there were many times the author referred to male characters as her and female characters as he). The author even confused at some point which character was speaking about whom. There were so many times when sentences didn't even make a complete thought or statement. Here is a suggestion for the author. Your story has a lot of potential. Step back, read through your own work, correct all the mistakes which makes this story such a tough read, then release it over again with the revisions. When I am spending so much time on every line trying to figure out what was being said and cirrecting it in my mind just to get to the next line and do the same thing, it becomes pointless to try. As this story is now I cannot even get to the pay chapters before I've given up. I could probably copy this entire story and rewrite it and release it while getting glowing reviews. Author, I would apologize for offending you, but I am equally offended by the complete lack of care you have for your own story to polish it before putting it out there for others to read.
