The four clans' protective formations formed a sphere around the entire clan, completely enveloping it within. The defensive power such formations could unleash was exceptionally formidable and comprehensive.
Moreover, under the watchful, tiger-like gaze of the Nine-Headed Green Phoenix Clan, the Phoenix Four Clans had continuously strengthened and refined them generation after generation, making the areas covered by the formations ever more stable and powerful.
Yet what had originally been their greatest advantage had now become a fatal flaw. If they wished to use the Sand Star King Stone, they had to shut down their protective grand formations.
Once that happened, they would lose the concealment of the formations. Furthermore, the Nine-Headed Green Phoenix Clan was not too far away and frequently kept watch over the movements of the other four clans.
If it had only been the Undying Underworld Phoenix Clan, it might have had a fair chance of slipping into the spatial rift by exploiting a gap in the Nine-Headed Green Phoenix Clan's vigilance.
But with all four clans acting at once, the spatial fluctuations caused when entering the rift would ensure that the Nine-Headed Green Phoenix Clan discovered, in the shortest possible time, that the protective formations of the four clans had suddenly been shut down.
