Meng Lei understood what Moro said more than anyone else.
Taking Earth as an example, ancient humans did not know that the ground they stood on was round, not knowing that they were living on a sphere. Beyond the Earth, they knew nothing about outer space, be it the solar system, the Milky Way Galaxy, or the entire universe. Even in the modern age, knowledge about space was limited.
That was the limitation of one's cognition.
In this aspect, those lofty Juggernauts were the same. They lived inside the vast universe, and they had never stepped foot beyond it or received any information about it. Hence, their cognition had its limitations too.
What was beyond the universe?
No one knew!
Perhaps, it was a world of nothingness.
Maybe, it was an even larger world.
What exactly was it?
Who knew!
