The inside of the scabbard was hollow, completely empty. But when Lu Xiaotian's divine sense entered it, he felt the Misty Flying Sword inside him stir restlessly, as if the Sword-Storage Case might suck it in at any moment. Startled, he hurriedly pulled his divine sense out of the empty scabbard at the case's core.
"Hmm?" As his divine sense lingered inside the Sword-Storage Case, Lu Xiaotian noticed that it gradually dwindled with the passage of time.
"This Sword-Storage Case can actually devour divine sense!" Lu Xiaotian was taken aback. He had never encountered such a strange sword case before. It was entirely unlike ordinary spirit-channeling magical artifacts and seemed somewhat like the talisman-spirit artifacts he had heard about.
Lu Xiaotian furrowed his brow and cautiously probed again with his divine sense. As time passed, his divine sense dwindled a little more. Just then, because he was deliberately watching for it, he noticed several dim specks flickering beside the empty scabbard. They vanished in a flash; if he hadn't been concentrating so intently, he might not have noticed them at all.
"This Sword-Storage Case must be an especially unusual kind of talisman-spirit artifact." Now that he had uncovered its secret, Lu Xiaotian understood why Xiang Qingcheng's divine sense had vanished without a trace from the case. It had been completely devoured by the Sword-Storage Case itself.
To use the Sword-Storage Case, however, he had to keep a certain amount of divine sense stored inside it. Otherwise, he wouldn't be able to use it in the middle of a fight.
A sword case that had to keep devouring his Primordial Spirit was certainly unusual. Lu Xiaotian rubbed his chin. But given how wondrous the treasure was, it was worth feeding it some of his divine sense and keeping it stored there
