Comments of chapter undefined of The Legendary Janitor

I wonder now. When Di Tou was stranded on the beast continent and was breaking through, it was established that he was losing his emotions and was growing more detached from the worldly matters due to his cultivation. I assumed this was the reason powerhouses were rarely involving themselves with the world: they were really detached from it and couldn't emote like normal mortals. So they had hard time connecting to people or caring at all. But this new information makes it seem that their feelings tend to run super hot and might actually affect their cultivation if they dare to care about stuff. And this is the reason they avoid building connections. What am I getting wrong here?
