The operation of this Seventh-Order formation was also very difficult, for its profound depth and immeasurable mystique made it hard to control.
Ordinary Array Masters struggled to control this Eighth-Order Array.
If Zhou Sui had not obtained the Array Heart Gu, which allowed this formation to nurture a Formation Spirit, it would have been challenging to manipulate this large array.
The only noteworthy advantage was the Secret Realm's entrance could move freely, allowing the maximum protection for the Secret Realm world without being invaded by external enemies.
However, such a Secret Realm world was sufficient for protection but lacked in expansion.
For those true spirit races, naturally, they would not choose such an Eighth-Order formation.
Their strength was powerful enough and didn't require this kind of "turtle shell" formation.
But for the current Human clan, this was already the best Eighth-Order formation.
