Not a chapter

Hey guys been a while...

Sorry in advance if you thought this was a chapter.

Anyways, I had been reading through the comments and a lot of me wanted to make the MC... Older, maybe 17 or 18...

I'm not really against the idea but at that point, I wonder if I should just restart the entire novel and maybe even change the system?

Let me know what you guys think, I wouldn't really be against restarting the book, since there are things I'm not satisfied with either.
