Yusuf Zuck didn't notice any markings or anything strange on the stone, but Crystal Locke could tell that Raul Graves was here.
Naturally, Yusuf Zuck was curious about where Raul Graves actually was. After all, with so many corridors here, Raul Graves, despite his reputation as a Half-Step Creation, was hiding in such a place. It was truly the case of a tiger falling into a flatland.
However, what Crystal Locke did next shocked Yusuf Zuck, as Crystal Locke bit her finger, letting a drop of blood fall onto the round stone.
As soon as the blood touched the round stone, it suddenly released a beam of light, and then, a portal slowly rose from the round stone.
Yusuf Zuck opened his mouth in astonishment. Who would have thought that this round stone was the portal to a hidden world?
"Come in," Crystal Locke stepped in first.
Just as Yusuf Zuck was about to step inside, he heard a long howl from within: "Crystal!"
