"This is..."
Looking at the Chaos Nest before him, even Chen Nianzhi was struck speechless.
It was a boundless, majestic, incomparably vast Chaos Nest. It floated amidst the endless chaos, shrouded in limitless chaotic energy, its true appearance impossible to discern.
Yet merely the portion it revealed already exceeded a billion light-years in size, like a great universe stretching across the chaos.
"So vast..."
Jiang Linglong was equally astonished. She could not help but draw a deep breath and say, "How could there be such an enormous Chaos Nest?"
The heavenly maiden observed it closely for a long time. After examining it repeatedly, she said, "This Chaos Nest stretches without end. It is absolutely no ordinary Chaos Nest. I fear it is a ninth-rank supreme-grade quasi-Daluo Chaos Nest."
Chen Nianzhi's heart trembled at those words. Chaos Nests could broadly be divided into upper, middle, and lower grades: lower-grade Taiyi, middle-grade Daluo, and upper-grade Chaos, corresponding to the realms of Heavenly Immortal, Daluo, and Chaos.
Each grade could be further divided into three tiers according to strength. This was the origin of ninth-rank lower-grade, ninth-rank middle-grade, and ninth-rank upper-grade Chaos Nests.
At first, the ancient Daluo cultivators from before antiquity had classified Chaos Nests into three grades and nine tiers, or perhaps three ranks and nine grades.
But the greater the gap between major realms, the more immense the difference became. The disparity between a ninth-rank upper-grade Taiyi Nest and a Daluo Chaos Nest was simply too great.
Likewise, among ninth-rank upper-grade Chaos Nests, some had even given birth to the embryonic form of a Great Dao, making them ten times stronger than ordinary ninth-rank upper-grade nests.
Thus, after the end of antiquity, the immortals added another grade above the three tiers. This grade was called supreme-grade; some also called it
