Bab 538: William's Team

"The last stretch is becoming harder to cross…" his rising speed was low to begin with. But now it was like a snail. If he had to devour couple hundred gold cores before to get a single spirit power point, right now he had to devour a thousand, or few thousands even to get that point! As for the silver cores, they became really useless, doing nothing at all!

"I need dark gold monsters," William knew if he kept doing this, he'd need tons of gold grade monsters, at least fifty thousand of them, if not more. The best option he got right now was to find dark gold monsters and consume their cores. But finding such scary folks wasn't that easy to begin with. Not to mention the scale of power of this grade was really scary!
