What are spiritual materials?

They possess Qi and a sense of spirituality, treasures that, if allowed to grow continuously, might ultimately transform into spiritual items, into living beings.

Such spiritual materials inherently have a subtle sense of awareness.

But for cultivators and blacksmiths who intend to 'skin and debone' them, 'tear them into pieces,' this spirituality becomes a burden instead.

For instance, a low-level blacksmith would be utterly helpless when dealing with high-grade spiritual materials with spirituality.

These spiritual materials could even backlash against the blacksmith.

Many high-level refiners try to preserve the spirituality within the spiritual materials, suppressing it, molding it, or nurturing it with their own power.
