"Once divine beasts reached the eighth tier, further breakthroughs became extremely difficult, especially the process of breaking through from the late eighth tier to the ninth tier. It was simply harder than advancing all the way from the first tier to the eighth tier. The reason was that even if cultivators helped divine beasts exhaustively uncover the rules within their bloodlines, there was ultimately a limit."
"That limit was the late eighth tier."
Billowing Primal Chaos Source Substance swept rapidly backward around them as Celestial Lord Chao and Wang Ba sped through it together. Celestial Lord Chao spoke quietly as they traveled:
"Except for a very small number of divine beasts with bloodlines of unspeakable nobility, those seeking a breakthrough cannot confine themselves to their own bloodline rules. They must also break free of the restraints those bloodline rules themselves impose upon divine beasts."
"But how difficult is that? Bloodline rules are the very foundation of a divine beast's strength. Breaking free of their restraints is like pulling out your own bones and growing harder ones anew... Thus, despite the Silkworm Dragon Realm's long history, the ninth-tier divine beasts it actually managed to nurture could be counted on one hand.
