Madam Magician's Explanation

As Lumian gazed at the peculiar soil, he couldn't help but recall the scene of Hela retrieving the Samaritan Women's Spring.

After a moment of contemplation, he retrieved gold bars and coins from his Traveler's Bag and ignited a blazing white fireball in his palm.

As the flames surged, the gold gradually melted under the control of his spirituality, forming a small golden box.

Lumian then used the flames as a blade to fashion a cover for the box.

Once the gold had cooled and solidified, he used the straight sword as a shovel to transfer the palm-sized clump of soil into the box before closing the lid.

After stowing away the golden box, Lumian noticed that the straight sword in his hand had become rusty and decayed.

Rather than being alarmed, Lumian was delighted. He muttered to himself, "That soil is indeed magical…"

This was one of his gains from the Dream Festival.
