In Fang Mu's designs, there existed several Spiritual Instruments that were dual elemental.
Even if it's just a bronze dual-element Spiritual Instrument, only a Spirit Forging Master can forge it.
The price of a dual-element Spiritual Instrument is much higher than that of a single-element one of the same level.
If someone is actually willing to sell it, it could fetch a price that is thirty times higher than usual.
If Feng Lin was a Spirit Forging Master, there wouldn't be much of a difference in forging single and dual-element silver-grade low-level Spiritual Instruments.
However, if Feng Lin was not, then his request would be embarrassing.
Concerning whether Feng Lin was a Spirit Forging Master, Fang Mu definitely couldn't directly ask.
But Fang Mu could use a roundabout tactic.
"Miss Feng Lin, I was very interested in Spirit Forging before, and I drew several design diagrams."
