These Upgrades Earn 42,000,000,000,000,000,000 Per Second in Idle Slayer

All it took was a lot of grinding. Then hitting that prestige button. Then grinding again. Every time I do this I make more and more money and that in turn buys more upgrades for more money. Sometimes I even get an upgrade for extra souls. Souls are the valuable resource since they buy the best kinds of upgrades.
