Infinite Evolution in The Apocalypse

I apologize for the 6-month hiatus. Life hit me in the gonads pretty hard but now I'm here to continue it after I organize everything and sort out the mess I left behind. Thanks for reading! --- The apocalypse is hard to survive in but Lucas Walker would say it was impossible. Having been thrown grumpily into the apocalypse from a long-deserved nap Lucas finds himself in a hell hole that is the apocalypse. Beasts of horrifying strength are everywhere and portals to other worlds have opened leaking strange energies and beings from them. With everyone in the world in chaos will Lucas be able to survive with the special class he received from the system that everyone has? --- By the way, the main class doesn't give many bonuses in the short term and only really comes to full power later on.
