400 The First Match

Shen Yi stepped forward, coming to a stop at the edge of the platform that overlooked the arena. "The first match of today is the blacksmith's exchange. The subject is metal purification. Both of you will be granted a piece of titanium crystal and will have thirty minutes to purify it. Whoever is able to purify it the most will be the winner. They will also be granted one thousand points, some course credit, and permission to keep both finished products. The first grade will receive thirty percent more if they win."

Titanium crystal? Tang Wulin furrowed his brow at the thought.
