The secret vault actually has this thing...
After quickly walking to the shelf, Ye Feng couldn't help but reveal a surprised expression in his eyes as he reached out and took the small object from the shelf.
It was a piece of iron filled with dark red rust, spotty with rust, and looking as if it were about to decay.
This thing, whether in appearance or in the pattern of its filigree, was identical to the other four pieces of iron he had in his hand.
"This object was acquired by the warrior Li Kuang from a cave dwelling within the Qilian Mountain Range. The material is unknown, but after analysis, it is not afraid of fire, nor does it corrode in water. Although its durability is extremely strong, its specific use has not been discovered."
Bowing his head for a glance, Ye Feng immediately furrowed his brow after looking at the label under the iron piece.
