Well, I spotted three grammer errors, but other than that, good chap. personaly, my favorite error was at the end. Master, Now! I instantly knew you meant, No! That was a little silly
By the way "charging/loading" a blow don't exist. is just the better way to lose time, and said to your target where you will struk. It's stupid, and no one do that in real fight : only in crapy and cheap novel, superhero or manga who try to make a "woo" and seem cool ... but are childish and totaly in the wrong.
Teerestrial is opposed to the one in sea, not oposed to one who are alien. It's Earthling the good word. Like "loading" is not the good word in the former chapter, but rush. loading is for filer on the PC.
There are many other like that, you need to re-read the chapter, or a good proff-reader man.
