- Description from Novelupdates

Derek Carter never asked for a System, an apocalypse, or the pressure of being humanity’s so-called “last hope.”He was just trying to survive the daily struggles of being an orphan in Paleview City—dodging bullies, scraping together meals, and lying his way into school. Life was already hard enough.Then, one day, a blue screen pops into his vision:[Warning: The world is doomed. Try not to die.]Yeah, great. Just what he needed—cryptic doomsday messages and no instruction manual.Now, monsters are creeping into the city, reality is unraveling, and Damien’s “legendary” starting stats are barely above zero. The System promises him power, but there's just one tiny problem—he’s never won a fight in his life.Armed with sarcasm, questionable decision-making skills, and the sheer refusal to die, Damien is about to embark on the worst (and possibly last) adventure of his life. Because if the world really is ending… he’s at least going to make it someone else’s problem first.After all, heroes are overrated—survivors get to tell the story.

In the wake of the apocalypse, betrayal doesn't just stab you in the back—it bites. Zorvax learned this the hard way. Abandoned by those he trusted, he didn't just become another number in the legion of the undead. No, his fate was far more peculiar.“I thought death was the end... I was wrong,” Zorvax mutters, his voice a gravelly echo of his former self. He's a zombie, but with a twist—he's got his human mind intact. Trapped in a decaying body with an insatiable hunger, Zorvax finds himself in a gruesome predicament that's just the beginning of his ordeal.Enter the 'Zombolution System,' a mysterious power he awakens that's as cryptic as it is potent. “They wanted a monster? I'll show them the true meaning of terror,”Zorvax boasts, with a smirk only a sentient zombie could muster. This dark gift is his ticket to ascend beyond a mere walking corpse, promising to unlock abilities that could crown him the emperor of the undead.As Zorvax hones his newfound skills, the line between man and monster blurs. Will his human intellect triumph, or will the beast within claim the throne? “This world has no place for the weak,” he arrogantly declares, ready to challenge fate itself.

The first time they met they had battled fiercely, just for a mere bunch of herbs. She needed it to save people, and he wanted to use it to save his own life.
