I Have Nine Quadrillion Simp Gold Coins - (Which ended or it was axed and ending was sh** but same vibes as this. After Becoming Financially Free, They Offered Their Loyalty - Good art but only 21 chapters so far. Same concept with Rich system in spending money
The Ultimate Wantless Godly Rich System - Another one but only 49 chapters. Also with Good art and not too flat colored one Legendary Car-Hailing System - Has 143 Chapters. Bit more into this than others because MC isn't too stupid or have too much harem simping moment.
