Grinding $70,000,000,000,000,000,000,000 To Earn More Money in Idle Slayer

I grind out all the money I possibly can simply so I can buy as many upgrades as possible. This simply leads to me making more money than before and then I can buy even more upgrades. I just repeat this again and again until satisfied, which is never apparently.
