The water bridge led to another floating island that is also different from the others. The third floating island is only made of rocks, but the strong point is the great wind pressure blowing them back to the water bridge. The floating island is basically a wind tunnel that pushes those that wants to traverse to the end.
This is the first time that the group encountered difficulty as they could barely reach the middle. The golem should only appear when they reach the middle, but they cannot do so. Even Kanlaon and Sirius' body could not easily block the wind pressure as it lifts them up.
The wind direction is not just a horizontal, but it curves upward to make sure that those with feet cannot plant it on the ground. Even Kanlaon cannot adjust the wind temperature to make sure that the wind pressure gets erased. It seems that this wind is unnatural as it is not affected by temperature changes.
