The day Louis discovered his girlfriend's betrayal, he died from a gunshot wound to the head. Fortunately, fate smiled on him and allowed him to be reincarnated in a magical world as the youngest son of an SSS-class family.That same day, he awakened his Class—an event that should have marked the beginning of his rise.Instead, it marked his downfall.[Ding! You have awakened an SSS-Rank Class.][Class: God of Money][Rank: SSS]A god? Yes, that's beautiful. But a god of money? In the eyes of his proud family, that title was a joke—an insult. The weakest, most useless Class imaginable.So, they banished him, stripped him of the family name, and cast him aside without a second thought.But they were unaware of his skill, abilities, and the potential that money could bring.He smiled as he saw himself banished and looked at the system.“If you fire me, it's okay. I'll keep creating missions even if I end up in a garbage dump, and I'll come back for your heads someday.”Two system messages flashed before him.[Your actions generate money, and money makes you stronger.][You have the ability to create missions.]Under the influence of his newly acquired Class, he will delve into all the magical paths this world offers, become embroiled in political intrigue, and conquer kingdoms on his own.“Money? I'm the God. Women?” That's fine—I have plenty.
