Two hours later, Ye Wudao finished making the last four Immortal Artifact Array Disks.
He first picked up the Formation Disk for the "Wind Fire Thunder Lightning" grand formation that he had refined earlier and erased the runes on it.
The next second, eighteen Formation Disks floated before him on their own.
He began refining the runes onto the Formation Disks, followed by the most crucial step—refining Immortal Power.
Eighteen Formation Disks required nine palm-sized clusters of Immortal Power to refine.
Each cluster of Immortal Power took roughly an hour and a half to refine. In other words, refining these eighteen Formation Disks would take around fourteen hours.
There were twelve hours in a day, and two hours had already passed while he refined the Formation Disks.
Thus, the one day he had told Wang Jian about was actually a little short.
Even with over a thousand Treasure Artifact Formation Disks helping him shorten the time needed to make the Formation Disks, it would still take a day and a half to succeed.
Without those thousand-plus Treasure Artifact Formation Disks as a safety net, refining a single Formation Disk would take him half an hour. Making fourteen of them alone would take seven hours.
Adding the time needed to refine Immortal Power, it really would take two full days to complete all the Formation Disks.
These thousand-odd Treasure Artifact Formation Disks had truly helped him greatly, saving him five hours.
While Ye Wudao refined Immortal Power here, the Demon Race had already retreated their battle line to the border.
All the Human Race cultivators had fallen back to the edge of the cliff. One more step back, and the battlefield would shift from the Demon Domain into the North Heavenly Domain.
Both sides had suffered considerable losses, but no battle
