章 2288: 1044, where did this sword embryo come from?

At this moment, Han Muye was clearly a youth in a cyan cloth robe, with a thin face.

The piece of black metal he was holding in his hand was extremely heavy.

This was Primordial Iron, an additive in the sword refinement process that could make the Dharma artifact even sharper.

However, Primordial Iron is not a precious spiritual material and could only be used to refine the lowest level of Dharma artifacts.

Such low-level swords were common in the Weapon Refinement Hall of Nine Mystic Mountain of the Western Frontier where Han Muye used to work.

Clutching the chunk of iron, Han Muye followed the team ahead until they reached a large furnace with flames rising high.

That furnace was one of the refining furnaces, though it appeared quite rudimentary.

In front of the furnace, a soot-covered old man with a hammer in his hand, a worried look on his face, was listlessly hammering a sword embryo.
