Enjoyable, a LN that focuses more on the monsters of the fantasy world instead of the humans. Definitely worth the read. Child protagonist makes interactions between the characters interesting if not a bit weird at times.

MC is OP, calculating, ruthless, and fun to follow. The only problem I have with him is his lust for revenge fizzing out for a while.

The author also has no idea what he's talking about when it comes to physics so a word of warning for people who can't look past that.

There is a lot of work that goes into building the world and the different species that inhabit it, as well as a good amount of detail into the game system that is going on.
