What's A King Without A System?

Summary

(Author's note: The first volume is basically a very long prologue. The 'Battle of the Beginning' chapters will be more representative of what to expect from future volumes. If you don't like kingdom building, item/skill upgrades and relationship progression then, sorry to say but, it's not going to be for you.)The world as we know it is about to end. Billions of lives will be lost, countries devastated and society left in ruins. But if you have the power to save it, would you?Zel Huertazuela has had a life that's full of let downs.

I’ll be an engineer then, those pay well right?”“Get a work that you would do even if you don’t get paid for it? What the hell kind of fantasy is that?”But that would have been it if it weren't for his sudden ability to live a lifetime in the span of a dream that lasts a night."Wait, this isn't the hospital?!""Where's my wife!""Now that I'm back, I'll be rich!""I'll fix the mistakes I made, there won't be any more regrets for this guy!""Monsters?!

Enjoy!)
