Lilia, standing nearby, noticed Lucius deep in thought.
He was considering what materials should be used for the foundation of the pet shop.
She bowed gracefully. "Master, may I offer you a suggestion?"
Lucius raised his eyebrow, intrigued. "A suggestion? Do you know of good materials?"
Lilia nodded firmly. "I do. In fact, some of the most important parts of this mansion were built with it."
Lucius's smirk widened. "I see… Please, enlighten me."
Lilia then began to explain it to Lucius.
"This metal does not have a known name—it was discovered by the past owner of this mansion, and its source is hidden beneath us."
Lucius's eyes sharpened. "A mine beneath the mansion? Go on."
Lilia continued, "The metal looks similar to silver, but it is far stronger than diamond while being significantly lighter than most metals."
Lucius nodded slowly, intrigued.
