As everyone knew, demon beasts' cultivation was divided into juvenile demons, Lesser Demons, Great Demons, Spirit Demons, and Tribulation Demons.
Of these, 1–9 years made a juvenile demon; 10–99 years, a Lesser Demon; 100–999 years, a Great Demon; 1,000–9,999 years, a Spirit Demon. Anything above ten thousand years was a Tribulation Demon.
Every one of these stages brought a qualitative transformation. This also meant that the later a demon beast's stage, the less noticeable the effects of raising its cultivation became.
If a demon crystal containing a hundred years of cultivation were absorbed by a juvenile demon, it could propel it straight into the Great Demon stage. But once it reached the Tribulation Demon stage, even a hundred such demon crystals would only add ten thousand years of cultivation. To a Tribulation Demon, that degree of increase was nothing more than a drizzle, a trifling scrap not worth looking at.
Most of Chu Yun's main demon beasts were already at the Tribulation Demon stage. Yet their cultivation was only around one million years. Tribulation Demon cultivation was exceedingly difficult to raise. By conventional wisdom, accumulating it required vast amounts of time.
Chu Yun had risen to prominence far too recently. Especially compared to those Marquis- and King-level experts—who among them was not several centuries old?
This was also the chief factor constraining Chu Yun's combat strength.
Chu Yun had fretted over this before, but there was nothing he could do. There was no shortcut. What he had never expected was that the Divine Treasury World contained a massive stockpile of ownerless demon crystals.
Though he had only extracted half of the reserves, it was already enough to bring an earthshaking transformation to the cultivation of the demon beasts in Chu Yun's hands.
On the very night he extracted the ownerless
