Portal Stone was similar to a Teleport Scrolled, with the only difference being that a portal stone enabled a player to traverse to other planes.
Although it sounded amazing, one needed to understand that a portal stone was not some cheap item.
It cost 10 gold coins and it was a one-time usage.
The one-time usage means that a player could traverse to another plane and return to their original location. Once the traversal was completed, the portal stone would be rendered useless.
With that in mind, the operation that the Malefic Order Guild spent to ambush them was extremely costly.
"Where did you obtain these portal stones?" Xu Feng raised the question.
"Sorry, but it's confidential." Azalea apologized for being unable to speak of the source.
"Is that so? Then is it confidential only to the top guilds in your plane?" He pressed further.
Upon hearing that, Azalea chose to remain silent. Despite being silent, the reaction was enough for Xu Feng to know what the answer was.
