Jiang Ming surmised that this was probably why the Quasi-Immortal Emperor realm was so difficult to reach, and why those who attained it were so rarely encountered.
So that was it.
He understood now. These were the shackles of the world itself.
A Middle Thousand World, even one of the very highest caliber, could accommodate an Immortal King Colossus. But anything beyond an Immortal King Colossus would surpass even that world's Heavenly Dao.
This was probably why those Dark Quasi-Immortal Emperors beyond the Boundary Sea Dam, each more ruthless than the last in their pursuit of a breakthrough, had ended up utterly alone.
To become Quasi-Immortal Emperors, they had sacrificed their home universes to themselves, sparing not even their own families.
One could say they had truly become as heartless as the Great Dao. In pursuit of attaining the Dao, they had ceased to be ordinary beings with emotions and become cold, unfeeling monsters.
Taken as a whole, this Perfect World was a Great Thousand World, capable of supporting the emergence of Immortal Emperors. However, after surpassing the Quasi-Immortal Emperor realm, it became very difficult to live within a Great Thousand World.
Their own Great Dao would suppress the Great Dao of a Middle Thousand World. Every breath they took could stir up a storm of spiritual energy throughout one.
Jiang Ming understood this more clearly than anyone.
His true body now could not fit within even a Minor World. It simply could not contain him.
If he breathed freely within a Minor World, a single breath could drain it of all its spiritual energy.
An existence like him was a nightmare for a Minor World. It was best that he never entered one, lest a moment of carelessness destroy it.
