With Lu Hui's Instant Movement combined with everyone else's Mirror Light Technique, they estimated they could finish in about a hundred years.
This was only a three-star Starry Sky Map task. Even Eternal Life Realm powerhouses without Instant Movement or the Mirror Light Technique would need a long time to complete it. But the task's greatest advantage was its safety. Time meant little to those in the Eternal Life Realm.
Compared with capturing a tributary of the River of Time, anyone would rather take this task.
As for the danger, it came from being in an unfamiliar place. No one knew what they might encounter.
So after Lu Hui and the others stayed behind to draw the Starry Sky Map, Lu Yin visited every few years. In this way, a hundred years passed.
During those hundred years, Old Ancestor Lu Yuan's group had finished mapping the surrounding area within the range an ordinary Eternal Life Realm powerhouse could cover in fifty years. Their efficiency was much higher than Lu Hui's group, though Lu Hui's group was also nearly done mapping the Threefold Universe's starry sky.
Drawing a Starry Sky Map naturally meant discovering civilizations.
They found several Universe Civilizations, and Lu Yin absorbed the Green Light Spots from each of their Divine Trees.
They also made another discovery: a black scale.
While Old Ancestor Lu Yuan's group was drawing the Starry Sky Map, they found a black scale drifting through space. It was an unexpected bonus.
The scale recorded a conjecture that Ancestor Mountain had once heard.
"Does every living being see the Cubic Distance the same way? Or does each see it differently? Are the choices living beings make based on their understanding of common sense, or on the common sense of their own understanding? What we call right
