Su Yu's eyes flickered. "Is that really the case?"
"Junior brother Su, you don't need to suspect me. I believe that you have surely come in contact with such Treasure Talismans before," Bing Wuqing said.
Su Yu had come in contact with Treasure Talismans. Elder Jing's Formation Breaking Hammer's Treasure Talisman had been obtained by the Shao family in the past. Once it was activated, it would release the Formation Breaking Hammer's phantom image, which possessed the Formation Breaking Hammer's true power. However, it could only be used once.
Moreover, Treasure Talismans were quite rare because making them would greatly damage the original magical treasure, and if too many were made, the magical treasure would even be destroyed.
The magical treasures used to craft Treasure Talismans were usually objects which couldn't be used by their owner, and since selling them would be a pity, they would just decide to use them to craft Treasure Talismans.
