Seeing him so certain, Yang Zhengshan picked up the Formation Disk and sensed it carefully. Sure enough, he sensed the power of the Great Void within it.
"This needs to be refined, and it also needs to integrate the aura of the grotto-heaven into it. Uh, as for exactly how to use it, I'm not very clear either. Old Ancestor should study it himself!" Yang Jizhen explained somewhat awkwardly.
A Cave Heaven Portal, as its name suggested, was a magic treasure specially refined for a grotto-heaven.
Although Yang Jizhen had refined it according to the concept in the Void-Refining Scripture, he did not have a grotto-heaven himself, so naturally he had no way to test it.
So whether this thing could be used or not, he could not be certain either.
Newly refined magic treasures were easier to refine. Yang Zhengshan spent less than two hours refining this Cave Heaven Portal.
After refining it, Yang Zhengshan carefully comprehended it again, and only then did he come to a realization.
This Cave Heaven Portal was not the same thing as the Cave Heaven Portals that the Spirit Source Land had possessed before.
The previous Cave Heaven Portals were inherent to the Spirit Source Land. In other words, they were companion magic treasures generated by the Spirit Source Land itself, so they were integrated with the Spirit Source Land.
As for the one Yang Jizhen had refined, strictly speaking, it should be called a Grotto-Heaven Teleportation Array.
However, it was also different from a normal teleportation array. A normal teleportation array needed two or more matching arrays to function, forming long-distance teleportation between two places or multiple places.
This one, however, only needed one to connect to the grotto-heaven.
Thus, it was much easier to refine.
Teleportation arrays belonged to third-rank formations,
