As Qin Ran pinched the [Silver Ferry Coin] between his fingers, the power of Gluttony immediately stirred.
Without any further guidance from Qin Ran, it instinctively began devouring the power within the [Silver Ferry Coin].
[Mental Attribute broke through one layer of the seal, C- → C] [Mental Attribute broke through one layer of the seal, C → C+] [Mental Attribute broke through one layer of the seal, C+ → B-] [Mental Attribute broke through one layer of the seal, B- → B]
The first three consecutive breakthroughs were no different from before. They were completed after consuming two [Silver Ferry Coins].
The only thing Qin Ran had not expected was that the fourth breakthrough, raising his mental attribute from B- to B, consumed a full two [Silver Ferry Coins], as much as the previous three breakthroughs combined.
"B, huh?"
The sudden increase in consumption made Qin Ran frown.
At an exchange rate of thirty [Copper Ferry Coins] to one [Silver Ferry Coin], the two [Silver Ferry Coins] consumed by three consecutive breakthroughs amounted to twenty [Copper Ferry Coins] per breakthrough. Taking the two earlier breakthroughs into account, it was clear that breaking through a layer of the seal below B- required only twenty [Copper Ferry Coins].
Above B-, however, the number of [Copper Ferry Coins] required shot up.
It took sixty [Copper Ferry Coins]!
Qin Ran had anticipated a change at B-Rank, but he had not expected such a large increase.
And that was hardly good news for him.
According to the attribute classifications Qin Ran knew, B was only the first threshold. Beyond it were Entry Rank and Tier V.
If breaking through one layer of the seal at B-Rank required sixty [Copper Ferry Coins], what about Entry Rank? And then there was Tier V!
