He only needed about a thousand blue ability balls to have a five percent chance of refining a golden ability ball!
This probability, actually, was not much of a problem.
After all, refining ability balls required at least ten white ability balls and only had a twenty-five percent chance of appearing blue.
That's to say, under normal circumstances, refining white ability balls into blue ones and then using blue ability balls to gamble on golden ones, didn't make much difference.
However, Shen Hao possessed a "Ability Ball Furnace" cheat, which could lock in probabilities greater than five percent!
This meant he could exchange forty thousand white ability balls for four thousand blue ones, and then further exchange them for four golden ability balls!
The efficiency of obtaining golden ability balls directly quadrupled!
Yet this wasn't even maximizing use, twenty-five percent could be locked in just like five percent!
