That slash deserved to be recognized as a sword attack of immortals, perhaps even stronger than that. Patriarch Xue Pao thought it was a profound immortal's Sword Intent.
That would be petrifying.
He knew that immortals were divided into three realms. 'Half immortals' weren't worth mentioning as they were only average, but 'profound immortals' were much stronger. Even if he managed to free his body, Patriarch Xue Pao would never want to challenge a profound immortal.
If he was so unfortunate that he stumbled across one, he would try his best to steer clear of their way.
This was the reason beyond Patriarch Xue Pao's hesitation earlier. After giving it more thought, he figured that Curator couldn't possibly be a profound immortal.
