There were many things in the world that could block magic power. Glutinous rice juice, for example, was an exceptionally effective anti-magic material. Large castles were almost all built using glutinous rice juice as a binding agent; castles like that could resist the impacts of magic and battle aura while remaining sturdy.
However, glutinous rice juice merely resisted magic. It could not prevent magic power from seeping through.
Basically, very few items could block the penetration of magic power—not even dragon-produced gems and crystals. A gem's magic power could endure for a long time, but that was mainly because gems possessed a condensing effect, automatically drawing in the free-floating magic power in the air.
Crystals had the same effect, though it was extremely weak. Once their dragon magic was exhausted, they lost that effect.
That was why the gourd's ability to store magic power had suddenly awakened Liszt. He wanted to probe the secret hidden within it—why it could isolate something like magic power, an existence distinct from matter.
"While having the Magic Guild develop the gourd's value, it seems I'll also need to contact A Ke and have her investigate its secrets... I can try feeling my way through it myself as well. I always feel that this tiny gourd conceals an enormous secret, one tied to my own opportunity!"
Unfortunately, the gourd truly was just an ordinary gourd. He turned it over and examined it again and again, but found no further clues.
He could only set it aside for now. Looking at Keli, the Gourd Great Elf swinging from a vine, he said, "Keli, you really are my little lucky star. The gourds you cultivate are very important... It looks like you haven't been very happy staying at Tinder Castle. How about I teach you a song?"
