Material’s Analysis

Samuel shook his head but he still accepted this arrangement.

"Which professor is the one who researched materials here?" Samuel asked the general who came with him. 

"It's Professor Brown," the general replied.

Samuel nodded and then said, "I have something to show to him. Can you tell him to come?"

"Yes."

With that, the general instructed the soldier nearby to call Professor Brown. Professor Brown has been very busy researching the ground, rocks, and other things around.

But when he heard that Samuel has something to show him, he still came out obediently.

After Professor Brown saw the ore, his eyes widened.

"Do you find this in this crack?" Professor Brown asked.

"Yes, can you process it quickly?" Samuel asked.
