Under the Eight Trigrams Diagram, he discovered five movable round stone balls. As he gently touched them, he found that these stone balls were also engraved with the Eight Trigrams Diagram, mirroring the pattern above.
This discovery filled Lin Beichen with excitement, as if he had glimpsed the dawn of hope. He began to rotate the stone balls below in accordance with the diagram above, carefully aligning each one.
However, when he aligned all five stone balls to perfectly match the diagram above, the stone door showed no sign of opening at all. Lin Beichen's heart sank. Could it be that he guessed wrong?
"Is this not the mechanism to open the stone door?" he muttered to himself, filled with doubt.
He felt it made no sense; since these mechanisms were installed on the stone door, could they merely be decorative?
Unwilling to give up, Lin Beichen carefully explored the entire stone door once more with his hands, hoping to find some change.
