The clash between Saine and the Dark Nether Death God over the cross-dimensional coordinates lasted for hundreds of years.
This confrontation did not involve any large-scale collision of legions.
For a very long period of time, even the vast majority of experts within the Illusory Sea Maze could not tell what the two sides were actually doing.
Only the Time-Space Altars that kept collapsing and then lighting up again proved how fierce the resistance from the direction of the Dark Universe time-space was.
The Dark Nether Death God was one of the most difficult opponents Saine had encountered in recent years.
It was not that his power was necessarily stronger than the Lord of Evil Swamp's.
Rather, he was clear-headed enough, and vigilant enough.
Every time Saine locked onto a coordinate that might lead to the Dark Universe time-space, the Dark Nether Death God would immediately counter it.
Sometimes, he used the Origin of Dark Universe to forcibly push the coordinate off course.
Sometimes, he poured Death Tide into the remaining passage, causing all the rule information Saine received to be contaminated.
On several occasions, the Dark Nether Death God even deliberately left behind clues to passages that seemed complete.
But what lay behind those clues was not the core region of the Dark Universe time-space.
Instead, it was a stretch of Dark Turbulence where even Level-10 Transcendence Realm experts might lose their way!
During the early analysis process, Wall-E had nearly followed one set of false coordinates and opened the wrong passage.
Fortunately, Alarm Clock Girl discovered in time that the time scale corresponding to that passage had a subtle discrepancy from the time when the Dark Universe Time-Space Legion had withdrawn from the Illusory Sea Maze back then.
Saine then separated this set of coordinates on its own.
