However, before the old steward could say anything else, the amount of black sand began to decrease as he watched.

Why was it decreasing?

What was going on?

To his astonishment, as the black sand disappeared, refined iron started to appear on the ground, and the iron had clearly been purified with fire.

"What… is going on here?!" The old steward couldn't believe his eyes.

The black sand couldn't just turn into refined iron all by itself!

Shrugging, Feng Wu pointed at something in front of them. "See for yourself."

The old steward's eyes widened.

He saw a small, fist-sized bird swallowing the black sand. However, it was doing something else at the same time!

As it ate the sand, refined iron came out its other end!

The old steward watched this in astonishment.

That was impossible!

He couldn't believe it!

He stared at Feng Wu. "This bird can refine the sand just like that?!"
