[Hilarious, Absurd, and Supremely Satisfying]
A naive young man suffers betrayal and heartbreak, but gains the greatest Ruler System of them all, along with a scatterbrained System administrator thrown in for free. From then on, he conquers everything with absolute strength and crushes all the worlds beneath his heel.
Bad at studying? I have the Ruler System. Knowledge comes to me as easily as breathing. Being top of the class is nothing, and even the world's leading scientists have to call me Teacher.
Bullied by powerful enemies? Attacked by mighty clans? Hmph! With my domineering aura sweeping across the world, I don't even need to spare them a glance. They'll all kneel and sing my praises.
Aliens are invading Earth? Easy. I'll capture them all and raise them. Hmm, a few new dishes for my restaurant sounds pretty good.
Gods, demons, ghosts, and monsters from other universes are descending? What's there to fear? I'll beat them in no time... They want to be my slaves? That depends on whether they're worthy.
Sir, you say you've mastered the laws of the great universe and become God? Sorry, the laws are nothing but my grandsons.
