Upgrading To $207,000,000,000,000,000,000 Per Second in Idle Slayer

It's all about killing those creatures as fast as possible. Every one we kill adds to our collection and we use those for the best upgrades. Basically I just use those to make more money than ever before which means more damage and therefore more souls again. Plus every time we prestige we get an earnings multiplier.
