I had decided to finally evolve at long last, I could evolve now that I ate two Rank 5 Mana Cores, however, there was a big problem with all of this right about now, a big one that involved…
System, why didn't the Rank 5 Mana Core gave me as much power as I thought it would be?!
<They were old, Mana Cores lose their mana over time, these two had been sitting for almost a thousand years. Over time, they lost over 90% of their original mana reserves… but they were still better than normal Mana Cores, you should be able to reach Peak Stage in Rank 4 after evolving…>
I see… I guess the path is really an arduous one, huh… Should I eat the other Mana Cores of Rank 4?
