Basketball's Kryptonian Gold Overlord

Intro: Synopsis: A top-up system: the more money the owner earns, the more top-up points they generate. These points can then be spent in the system's store. Earn one sum, spend two. This is the most satisfying system in history. ps: I already have two complete and well-regarded works: "Summoning Generals of the Sports World" and "Basketball Godfather of the Sports World."
