Quiet Down, I’m Exorcising Spirits!

I thought that after I got the system, I would start the plot of slaying demons and subjugating demons, but the result was that I was pretending to be a slap in the face. Only four days had passed in the 150th chapter. In addition to sleeping and practicing, all kinds of things happened one after another. Then he started to show off and slap in the face. The protagonist appears and does nothing, and then a group of people come to ridicule him for no reason. After a while, another group of people support the protagonist. Just three meals a day. Maybe add a late night snack. Don't even know what's so good about this kind of thing?
