Jacob conducted a meticulous examination of the cave. It appeared barren, containing nothing but the pervasive frost energy and shimmering ice crystals. Jacob bit his finger and fished out a talisman paper, sketching a circle on it. He then lit it with his spiritual fire.
While Jacob wasn't as skilled as Frazier in casting charm spells, he possessed the knowledge to cast a spell to reveal concealed arcane arrays. As the charm was consumed by flames and vanished into ashes, the arcane array materialized before Jacob's eyes. The path beneath their feet transformed into a chessboard with numerous squares. Only those who correctly guessed the steps would be able to pass through safely. Anyone who made a wrong move would promptly succumb to the frost energy and turn into ice. After careful observation, Jacob felt the urge to laugh out loud.
