Capítulo 902: Making a Sword

Alex poured his Qi into the furnace as he sped up the process behind the melting of the metal. 

Not doing anything would also work in this situation as there was a formation being used to heat up the metal inside, but since he was being apprenticed, he did as asked.

Once the metal was melted, he pulled out the crucible and poured the metal onto a mold. He waited just long enough for the shape to solidify, and then pulled the still burning hot and red metal out from the mold and onto an anvil before starting to beat it with a hammer that he had received. 

He hit the metal for as long as he could before it solidified to the point that hitting simply made no difference anymore. After that, he put it back on the furnace to make it soft again.

His teacher sat on a stool not far away, watching every little move, but not teaching him anything at all unless he made some mistake.
