In Zhong Yue's world, there truly were cultivators who stood at a ceiling no one could surpass.
That ceiling was River Jiang Nan.
In the vast world Zhong Yue inhabited, there were several Protagonists, and Zhong Yue himself was one of them.
River Jiang Nan, of course, had once been a Protagonist-level figure too.
But no matter how hard the other Protagonists cultivated, even at their limits, they could never stand on the same level as River Jiang Nan, let alone surpass him.
This world could have only one at the top. River Jiang Nan had become Primordial Beginning, and that made him the only one.
Put simply, this world's Primordial Beginning had gathered every Great Dao and cultivated each one to the End of the Great Dao.
Those that existed and those that did not, those already born and those yet to be born—all of them.
Every Great Dao and every possibility were encompassed by Primordial Beginning.
That included Zhong Yue's Yi Dao, the Great Dao of Primordial Chaos belonging to Su Yun, a protagonist yet to emerge, and the Dao of "Sameness" cultivated by an earlier protagonist.
When those three Great Daos had first arisen in the hands of those three Protagonists—no, before the three had even comprehended them—River Jiang Nan had already encompassed them and automatically reached the level of the End of the Great Dao.
If Zhong Yue's Yi Dao gained new variations in the future, and he comprehended new Great Daos and incorporated them into Yi Dao,
Then, once he reached the End of the Great Dao, he would still find Primordial Beginning there. He would find River Jiang Nan's Primordial Beginning.
Only at the End of the Great Dao would one behold Primordial Beginning.
In this world, that was an eternal truth.
The End
