Self-discipline! Have You Ever Seen Marin Vando at Four in the Morning?

Roy the slack traveled through the world of pirates, activated the self-discipline system, and was forced to become the self-discipline demon king.
But he doesn't need to be self-disciplined by himself, and he also pulls others to self-discipline...everyone is afraid of him when they see him.
Jogging with Kizaru, pulling Aokiji to drink hot water, and letting Akainu take an ice bath...
Help Aunt and Blackbeard lose weight, let Karp quit snacks, and let Whitebeard quit drinking...
Aokiji: Seeing Roy fighting, I was so excited that I went to Whitebeard to fight, and I almost got cut.
Kizaru: Seeing Roy's training, the old man was so excited that he immediately got up and did ten push-ups. He almost had a myocardial infarction. It was really scary.
Akainu: Roy, isn't it good for you to work 8 hours a day as a general?It’s fine to work overtime, and to go to the military academy to teach and delay the classroom, you make the old man very embarrassed.
The Warring States said angrily: Roy's bastard is self-disciplined, so what's the point of doing the work of the marshal, the old man?
Whitebeard (helpless): Roy and his family*..
