How does a 65 year old, ex navy seal survive the integration into the multiverse? What if, in the case of wrong time wrong place, that individual was integrated as a monster and hunted by fellow humans in the noob zone for easy XP? What if, to top it all off, that individual has a really low luck score and can't get it any higher?
Well, it takes a love of pot roasts, an ability to talk to oneself, and 40+ years of survival skills to make it all happen. Oh, and maybe just enough unluckiness and a proclivity to undergo hardship to become unstoppable.
