A few months later.
Boom~~
Zhou Sui, who was cultivating in the Profound Yellow Realm, suddenly opened his eyes. He sensed that the Array Heart Gu had broken through at this very moment, ascending from the Third Class, High Grade to the Fourth stage.
This meant it had completely mastered Feather Gate's Sixth-step Immortal Formation, the Liang Yi Yin Yang Yu Hua Formation, and thus naturally progressed to a Gu Insect of the Great Luo Realm.
"Finally ascended to the Fourth stage?"
Zhou Sui sat cross-legged on the ground, feeling very calm. After all, the breakthrough of the Array Heart Gu was just a matter of course, and to him, it was really nothing.
Once the level of a Great Luo Immortal Array is reached, it is no longer just about forming a Cave Heaven World; it is a complete world with its own world barrier.
Thus, the Great Luo Formation is extremely powerful. Once activated, it can either imprison enemies within the world or block them outside the world barrier.
