1182 New Main Quest, Four Ancient Dao Seals

Continuing to keep an eye on the situation on the stone platform after the being in the dark miasma had been suppressed, Xuan Hao was shocked to discover that the old man had begun to repair the part of the seal that had shattered.

Given the difference in strength between the old man and the seal itself, it should have been impossible for him to repair the seal. However, he seemed to have the help of yet another strange artifact that allowed him to borrow a power far beyond what he could wield at his current cultivation realm. Allowing him to freely manipulate and in turn repair the damaged part of the seal.

Even then, it was obvious that the old man had a rather extensive understanding of the Dao of Formations. Far superior to anyone he had ever seen before. If not, it would have been impossible for him to repair the damaged seal.
