So here are my thoughts on the chapter.
First I don't think we needed to hear anything on the second core and expert energy gathering, I feel it's way too early to mention things like this, on top of that right after you wrote: "he doesn't need to worry about a second core"... So why should we care about it?
Second on the 34th line "So he had to waste time on that now, and one day when he was in his way to pick her up" I feel "So now he had to waste time on that. One day when he was in his way to pick her up" flows better.
Third when Marcus sees that the thug's body is made of a lot of metal the lines are in different groupings making it slightly awkward to read.
Fourth the second thug kinda disappears for some reason.
Lastly "A stream of High energy particles passed by Marcus as he was approaching," for some reason "High" is capitalized.
I know all of these are nitpicky but I was sad that I couldn't find anything last chapter so I had to vent this time.
Thanks for the chapter.
