So you use the System to cheat your way to higher levels? I'll raise the cultivation levels of everyone in the entire plane by a thousandfold! You'll get beaten down for sure!
The System gives you gift packs, and you're the only one with miraculous pills, treasures, and secret manuals? Then I'll make a whole set and scatter it across every street. Everyone will take a pill and become an expert, then pick up a manual and grow godlike. You'll still get beaten down for sure!
Modern good-for-nothing homebodies, useless except for attracting handsome men and beautiful women with their Mary Sue and Gary Stu halo Systems? Dream on!
I'll raise your dream lovers' emotional intelligence five thousandfold, so they can see you for the loser you are!
Surprised? Shocked? Still fantasizing?
Go home and work hard, one step at a time!
In short, cheating, golden fingers, being reborn, Systems, transmigrating, Mary Sues and Gary Stus: he forbids them all!
"Objection! You're just showing off with your Supreme God System!"
"Objection overruled! If you don't like it, too bad. That's what you get when I'm the God of Anti-Tropes!"
It's boring, this male protagonist is so useless.
