@danymu Yeah, that was a pretty funny detail if you think about it that way. However, you could also view it as the message reaching the king is nothing urgent, so he would rather use the time to do things in that town. In other words, it doesn't matter if it takes days or weeks.
if that mc is so focused on efficiency then he should realy just go and kill the noble and anyone else suspicious clean up the city and report afterwards
and as a bonus if he does it silent assassin style he can even sit around afterwards and trap whatever bird might come back to the nest
edit
would have given them a weeks time to prevent that shite with the spawning too
