Inside a much larger smithing forge, two people, one fox and one mermaid, were drawing blueprints, planning their next creation.
"No! I'm telling you, you can't just put in a few Qi-gathering arrays and call it a day! A Mystic-Grade weapon needs to be more than just self-sustaining! They need to have their own special abilities!" The mermaid argued, drawing up a quick prototype, only for it to get erased.
"Bullshit!" The fox yelled. "As long as a weapon's sufficiently durable and sharp enough, anything can be Mystic-Grade!"
"Yeah, if you just want a giant lump of metal!"
"Why does a damn sword even need its own abilities?! That's what the user's for!"
"That's why they're 'Mystical'! It's in the freaking name!"
"...Tch! How many things does a weapon need to have? First, it's Qi pathways. Then, it's Elemental Resonance for Earth-Grade weapons. Runecraft Infusion for Heaven-Grade, and finally, this nonsense, 'Spirit Power'...Whatever the hell that means."
