Came back to this after about half a year, what in the world happened?
He speedran....everything.
First was swordsmanship, was already god-tier from training with mom before arriving at the city.
Then magic, learn how to use magic from dad before going to the city, again, but improve some more over there.
Then it's taming, which he technically got 1 pokedemon all the way back during swordsman part already.
Then making a kid, which only get the 'anyway we get married' and the whole pregnancy/birth got off-screened by his 1 year of chasing after his sister and sorta learning stealth skill on the side.
And now we time skip a few years to saving the world from demon lord, while also bringing along his kids.
