Zane stood up slowly, closing the final book from the first floor. The soft click of the cover echoed quietly through the library. But it wasn't just the book's end that drew him to his feet.
Beep.
He looked at his wrist—the techno-watch shimmered softly.
"The battle power measurer is complete," he muttered with a slight smirk.
He smirked. "Let's adjust it to this world's mana frequency."
With practiced ease, he tapped the screen and began drawing faint glowing runes in the air, letting them sink into the watch interface.
"In addition... let's add hidden detection runes. Wouldn't want people knowing they're being scanned."
He sent a pulse of this world's mana into the device, carefully aligning the frequency, and etched a final rune to conceal its probing ability.
Click.
"All right. Time for a field test."
His eyes scanned the area. A man, quietly reading a book across the hall, caught his gaze. Zane extended his hand briefly, as if stretching.
Beep.
