This story strongly needs an editor. Typing and spelling errors aside, terminology changes back and forth it is hard to keep up. It gets really bad around the 400 chapter mark were the power levels terminology is either switched or not explained passed a certain level. Worldbuilding background changes that contradicts itself, then completely changes genre from SciFi to standard cultivation light novel with original story background thrown out the window. It is literally to separate book genres' mashed together as a "student exchange program" but it seems like the humanity vs the RED's doesn't exist anymore and the new characters no nothing of the scifi aspect of the story?? I might give up on this story.
