Now that's the Old Fart is dead he's travel far to gain back up with strong background. Well MC at least knew his limit.

All the villain says "that's impossible" when they are beaten into pulp.

That old fart tart life force, or power force completely shattered inside his body. I'd say that was him having a massive heart attack on the scene right there yup XD.

I wish the fat guy would've kicked the old fart lol, I thought he was going to do something the way he was staring at the old farts corpse aha.
