The Refined Obsidian Dragon returned to the workshop several hours later with a leather pouch filled with materials.
He tossed the bag before Yuan and said, "If you can craft a treasure while using half of the materials in there, I'll consider you worthy."
Yuan grabbed the bag and poured all of the materials out. There were twenty-one materials in total, and he didn't recognize any of them.
However, instead of panicking, Yuan smiled and muttered, "Interesting. This will be fun."
He suddenly sat before the materials, grabbed one of them, and started inspecting it in silence.
"..."
The Refined Obsidian Dragon's eyebrows twitched at Yuan's actions, and he sneered inwardly, 'At least he isn't completely incompetent.'
After spending several hours examining every single material there in great detail, Yuan closed his eyes and began doing mental simulations.
