Theory time, what if thot is trying to get away from his library? He spent years in a place that had almost no sound or other stimuli. Also no human interaction at all, any normal human would go crazy. He hates his library but this contradicts his lore, so he makes excuses to leave the library. Such as going to see Aura or trying all different types of search magic to report to Ainz about.

The shows called impulse

That is how investment works

When you’re sick you want heat because it kills the pathogens faster. This is why the human body is hot when you’re sick your body increases blood flow in the infected area, to make you hotter.

Most of the stuff you’re asking is already answered in the story. As for gaining bio pionts, and evolving to meet thier mom In the story it states that it’s only a possibility.Also about doing the favor for the kingdom it doesn’t explain why they did favor before killing all of them, its up for interpertation. In the story it States that the Mc became shin godzilla because the “dispise” humans, and loves distructions. I hope this helped in some way.

I can see improvements, I will read with great interest.
