CLASS CHANGE HERO: OP Prog LITRPG:REWRITING

It was supposed to be a simple surgery. At least that's what the doctors told Ryan before he woke up three thousand years in the future.  Stranded in a desolate research facility, Ryan finds himself in a body he doesn't recognize with abilities no human should have. To make matters worse, the reality he once knew is now overrun by goblins, zombies, killer robots, and twisted fairytales hell-bent on grinding him into meat paste. The reason isn’t something he’s done, but someone he’s protecting: a mysterious young girl named Lucy who may represent humanity’s last chance at survival. Or evolution. Fortunately, despite being surrounded by an ocean of enemies, Ryan isn't without a life raft.  Left with the recordings of those who experimented on him, Ryan must learn to harness his unique ability to Class Change and work together with Lucy to push beyond the limits that once defined mankind. In a universe where technology and magic have spiraled out of control, survival won’t come from what humanity used to be... but from what it’s willing to become.
