"Are you sure it's sulfur this time?" Arthur asked, his gaze sharp. "Last time, you brought me limonite."
At the mention of his past mistake, the man's face reddened slightly, but he quickly composed himself. "I can't say with absolute certainty, Your Majesty," he admitted. "But this time, we found it near a hot spring—just as you mentioned. Sulfur is often found in volcanic regions or near hot spring, so the chances are high."
Reaching into his pocket, the man carefully pulled out a small, rough crystal with a distinct yellow hue. He held it out for Arthur to inspect.
Arthur took the crystal, rubbing it between his fingers. It crumbled slightly, leaving a faint, pungent odor—the unmistakable smell of sulfur.
A slow smile formed on Arthur's lips. Finally, they found sulphur. I don't know why sulphur are so dam rare in this world but on earth it is one of the most common elements. Luckily, I started to assigned them to find sulphur as soon as I started to create potassium nitrate.
