It seemed the problem really lay in how she was channeling energy into it.
Still, the Compass did indeed need spiritual energy to work.
Just as Xue Fuyao was racking her brains to no avail, her finger touched a certain spot. A click suddenly came from the Compass, and a component on its surface fell off.
Seeing this, she looked toward the opening and discovered that an opening had appeared there at some point.
The opening was about half the size of her palm and took up half the Compass's area. Yet when she had examined it with the Heavenly Eye earlier, she had not noticed this opening.
"A spatial formation?"

However, looking at the size of the opening, she already had a vague guess as to what it was for and how she should use the Compass.
With that thought, she took a Spirit Stone from her Storage Ring and fitted it into the opening.
"Just the right size."
The instant the Spirit Stone was inserted, the dull, somewhat worn Compass began to give off a faint golden glow. Then the golden light gathered above the Compass, finally forming a pointer.
