His new spell [Granite Wall] reformed the broken wall to make it into an even stronger one, making sure none of the undeads would be able to use another path to enter the castle.
Now that Emery had learned a strong new spell, he quickly found his solution to beat the powerful wolf.
The reason for his previous hesitation was not only because of how strong the wolf was, but also due to how each and every one of its attacks had the ability to affect his spirit energy. Because of this, he had no choice but to constantly keep his distance from the wolf.
But now that he had this he did not have to do that anymore.
Not wasting another moment, Emery used [Shadow Root Binding] to stop the wolf, putting both of his palms on the ground, causing a long, thin granite wall to rise from beneath the ground. Right after, he controlled the wall to quickly cover the black monster like a blanket.
