"And now, I'm about to upgrade the Death Wave Skill from LV.MAX to Death Wave·Original LV.5, which will consume another bit of Ash Source. After this upgrade, I'll only have a little Ash Source left, yet advancing in rank requires four points of Ash Source.
But fortunately, the Ashen Treasure Boxes in the upcoming Demonized Swamp Zone should give me three more points of Ash Source, so I'm definitely not too worried about advancing in rank, the real concern is how to upgrade the professional skills acquired after rank advancement.
However, I might as well leave that problem for when I reach the Third Tier, even though it's quite close—something I'll face the day after tomorrow—but indeed, it's not immediately relevant to me."
Of course, the main reason is that even if Zhang Yanhang worries, he doesn't have any good solutions at hand, so he might as well ignore it for now, in any case, delaying is enough to deal with it.
