Control over the System

Starts with a question, truly begins with the answer, and soon ends with death. Well... I kinda need that Bam! Reincarnation saves the day once again and this MC is... smart? I wouldn't know, like author like MC I guess. After death the MC finds himself in darkness? or light? The place confuses him but everything is put together by the entity known as Ainz. Ainz allows him to wish for anything and everything he wants but only once. "Y'know those systems that fantasy web novels have? I'd like one of those but the difference is that I'll have full control over the quest and reward part." Ainz looks at this tall blonde dude and nods, this begins our path to reincarnation.
