Upon seeing the system prompt, a strong joyful expression appeared in Cao Xing's eyes!
"Haha! It really works!"
With this, the old mage Tyrone only needs to cast it once, and it's equivalent to all the walls being greatly reinforced, significantly increasing their defense!
However, Cao Xing also saw the system prompt. Although this layer of Rock Barrier exists permanently, if the Durability Value decreases or is broken, it still requires magic consumption to repair.
But thinking about it, it's quite normal.
