As he was still pondering the problem, he saw from the corner of his eyes that Peniel was stifling laughter. He glared at her, then said annoyingly, "If you know which part is wrong, tell me, please. Time is running out soon. It will be really frustrating if we fail this trial due to your amusement."
Peniel tried to glare back, but when she realized that Jack was serious, she retracted her playfulness.
"Fine!" She said and flew towards the rune formations floating in front of the rod. "You noticed these runes are arranged circularly, right? What about the displayed images that you had to memorize?"
"They were arranged in a straight row," Jack answered.
"Exactly," Peniel said. "Now there is a significant clue at that point because all spell formations that consist of more than one rune are always arranged in a circular formation, like the one you see here. There is no row arrangement for a spell formation. So it is not just about the runes, their arrangements are also important."
