After the surprise, Ye Zhen looked at the colored light gate at the end of the path and calmed down.
The reason Ye Zhen had blurted out "Secret Realm" was mainly because this colored light gate greatly resembled the one in the Universe Stone Forest Secret Realm within the Qiyun Sect.
According to the Qiyun Sect's texts, such colored light gates are usually created by powerful beings who forcibly gather the Power of Earth Vein to condense them, or they could be formed by skilled Array Masters using formations.
The former was very likely an entrance to a Secret Mansion Remnant Realm, while the latter, in most cases, served as transportation portals.
If it were a transportation portal, Ye Zhen felt the likelihood was very small. Normally, the operation of a formation needed the support of Spirit Crystals, and with Floating Cloud Cave being abandoned for so long, even the energy within High Grade Spirit Crystals must have been depleted.
"Nine out of ten, it is a Secret Realm!"
