The Origin Great Dao possessed Eternal Uniqueness.
Therefore, after Bai Yu united the Three Thousand Great Daos within himself, if he chose to open up a Great Thousand World containing three thousand complete Origin Great Daos, it meant that Bai Yu could not refine an Innate Supreme Treasure containing three thousand complete Origin Great Daos.
He could only choose one of the two.
It seemed like there was no choice, but there actually was.
Because Great Thousand Worlds could nurture Innate Supreme Treasures!
Not every Great Thousand World was as stingy and miserly as the Primordial World.
Although the Primordial World contained forty-nine complete Origin Great Daos, in theory, it should have been able to nurture forty-nine Innate Supreme Treasures.
Of course, each of those forty-nine Innate Supreme Treasures could only receive one complete Great Dao.
However, the Primordial World had another extreme option: nurturing a single Innate Supreme Treasure containing forty-nine complete Great Daos!
Yet the Innate Supreme Treasures of the Primordial World could practically be counted on one hand. Clearly, the Primordial World had not nurtured many Innate Supreme Treasures at all.
Take Qing Hong's Shanhai World as an example.
Qing Hong and Eastern Emperor Taiyi actually had rather similar origins. Both were innate divine beings with top-tier foundations, and both possessed Innate Supreme Treasures as their accompanying treasures.
Of course, Qing Hong's accompanying treasure could not be mentioned in the same breath as Eastern Emperor Taiyi's.
Although Qing Hong's accompanying treasure was also an Innate Supreme Treasure, it contained only one complete Water Dao.
The Chaos Bell, on the other hand, clearly contained multiple complete Great Daos.
Yet although Qing Hong's origins were inferior to Eastern Emperor Taiyi's, Qing Hong had successfully attained the Dao!
As far as Bai Yu knew, the Primordial World's Innate Supreme Treasures
