1848. Dead zones
The event didn't involve only Noah and his group. All the rank 9 dragons and the leaders went through the same process. Their bodies turned ethereal as gales made of chaotic laws filled the battlefield.
Noah couldn't sense the power that caused his ethereal form. He wasn't even sure that his initial idea reflected the true nature of his state. After all, his centers of power weren't reacting to the event. He didn't feel anything unusual.
Other ideas started to appear in his mind after he saw how the many enemies reacted to the event. The cultivators and the swarm fighting against the rank 9 dragons had to prioritize their escape at the sight of the raging gales. Still, the solid stage woman wanted to kill her opponents even if she had to sacrifice herself to complete the task.
