After a series of investigations, everyone finally discovered the true purpose of this Secret Realm. Within it grew an exceedingly special spirit medicine, but obtaining it was no easy task.
The spirit medicine itself had powerful guardians, but that was not the main issue. The key was the medicine's effect: after consuming it, it could actually stimulate one's own potential. That was right—it merely stimulated it. It neither increased nor diminished it.
By stimulating one's potential and using it to break through one's current bottleneck, one could achieve a breakthrough. At its highest effect, it could directly elevate someone at the Peak Spirit Venerable stage into the Spirit Saint Realm. Beyond that, it was useless, but rising from Spirit Venerable to Spirit Saint was practically ascending to heaven in a single step. It was immensely important to any person or any Sect.
A hundred people could enter every year. This place was simply too precious. If a hundred Spirit Saints were born each year, any Sect would become one of the foremost powers among the Super First-Rate factions in a very short time.
Most importantly, this stimulation of potential did not cause much damage to one's own potential; it could practically be ignored. It saved an enormous amount of time and could even allow people who had no hope of breaking through to become Spirit Saints. The temptation was simply too great.
Thus, a great battle erupted over this Secret Realm. Especially after the Ghost Medicine Sect declared that it would not control the Secret Realm and would instead let it benefit the other Sects, the conflict became even harder to contain. Huo Hai even suspected that the Ghost Medicine Sect had known about this Secret Realm all along. Releasing it now must have taken an immense amount of resolve.
