@AA well what you've seen and what you've understood are completely different. You seen the information in chapter 3 yet you still haven't understood the equation for leveling up. It required over 300 quintillion experience to go from 40 to 41, it took over a 100 quintillion to go from 39 to 40. The equation is 1,500,00 x 3 ^(L-11) = experience required. L = MC level. So MC is slow for the mathematically challenged and impossibly fast for the conceptually competent.
