What Am I Trying to Do by Picking up a Scumbag?

The protagonist in other people's books picks up money, treasures, and cute girls, but my protagonist picks up a despicable god? That god is ruthless and has no morals. If we agree to build up our character together, we can pull him back eight hundred miles! No matter, anyway, this guy doesn't cultivate immortality, doesn't upgrade, doesn't waste land, doesn't have a harem, he's "just an ordinary person." Huh? Why don't you get rich suddenly, you ask? His family is the richest man. Why not counterattack, you ask? So far, no one has been able to do anything to him... Why do you want to save your character, you ask? … Hey, just look down and you'll find out! Life is so boring, boring, and extraordinary.
