Purifying Metal Materials

Gan Moye quickly walked into the ventilation area and let out a long breath.

She wiped the sweat from her forehead and turned to look at Xiao Yun.

Xiao Yun had already walked up to the Earth Fire Furnace. He stood before it, his gaze falling on the churning magma inside the firebox. The dark red liquid moved through the furnace like fire dragons, and the heat waves it gave off warped the air itself.

His expression did not change, as if what lay before him was not a heat of several thousand degrees, but an ordinary pile of charcoal fire.

He took several pieces of Meteorite Iron from his Soul Tool and placed them on the Forging Table. The pieces varied in size, some as large as a fist, others as large as a washbasin. Their surfaces were pitch-black and showed nothing special, but they were extremely heavy in the hand.

Xiao Yun picked up one piece of Meteorite Iron, examined it carefully for a while, then set it on the Forging Table and picked up another. Gan Moye stood in the ventilation area, watching his every move with curiosity.

After Xiao Yun finished checking all the materials, he began the next step—smelting.

He put the pieces of Meteorite Iron into the Earth Fire Furnace one by one, controlling the temperature of the flames. Smelting could not be rushed. It had to be done slowly.

If the temperature was too high, the impurities could not be removed cleanly; if it was too low, the metal would not melt. When to raise the heat, when to lower it, when to hold it steady—every step required precision.

The first piece of Meteorite Iron entered the furnace. Under the high heat, it slowly turned red, softened, and melted.

The impurities oxidized under
