This layer of protective fog would not appear at normal times, but only when the Mountain Protection Array was fully activated.
Its appearance could directly expand the protective scope of the Mountain Protection Array several times over!
However, in reality, this protective fog area was not truly the gate of the White Dragon Branch Temple; even if it were shattered, it would not affect the Mountain Protection Array of the White Dragon Branch Temple.
The inner area behind the outer layer was the actual location of the gate of the White Dragon Branch Temple, guarded by an Array Protective Shield.
Only by destroying the formation foundation in this inner area could one truly damage the Formation.
The previous attacks by Zhou Chun and others hadn't even touched the gates of the inner layer.
But now, the attacks from the Golden Core Phase Cultivators rapidly tore through the tens of miles deep sea of clouds in the outer layer, striking the Array Protective Shield inside.
