I Reincarnated as a Dragon, and I Decided to Destroy Anything I Wanted to Destroy

I'm sure, I definitely died, but I found myself talking to an old man who baselessly claims to be God.
He tells my broken little soul, like in occasional generic isekai novel scenarios, he accidentally destroyed my puny human body. He said 'sorry' a few quick times, and told me I could reincarnate into another world. Yeah, of course I agreed to his generous offer like any sensible person would and I became some kind of white-colored dragon.
God offers me the basic job of preventing overpopulation of monsters in one of these game-like RPG isekai worlds with magic and stuff for a while. Sounds fun.
