I created my own system - Chapter 176 Succumbing to Darkness

Mathew survived the entire two weeks of the apocalypse. A great score for someone blessed with brains over the brawn. Yet, even he fell after just fourteen days, giving his all to save the one person he cared for.

But why does a death looks like watching himself from the third person perspective? Is this the purgatory to watch over his own shoulders at the mistakes he made? A punishment for Mathew's sins to repeat those mistakes over and over again?

But wait, what are the three clocks in the corner of his vision, one of which only five minutes away from ticking out?

There was nothing left to lose in his life.He had lived as a hero. He had started at the bottom and worked his way up to the top, at the end he become the best, yet he had always been betrayed by those he had tried to protect.Humanity did not deserve his protection.When everything went out and he could no longer even hope to beg for his life, he could do nothing but look up at the blood-red sky among the corpses of demons and angels.He wished for one more chance, just one more chance.And when that chance was given to him, he swore that he would change everything. He would no longer be a hero to save people, but an anti-hero to save the world.Sacrificing hundreds of people to save an elf, poisoning hundreds of people to save a group of half-demons.He didn't care about any of that anymore, he would protect those he cared about and send everything else to hell.Not even the gods or goddesses could stop him.
