The "surprise" that Zhang Tie prepared for Yan Feiqing was a beautiful female longuette.
There was no cloth in the rune instrument manufacturing skill promotion region. He could only find metal there. This longuette was made of metals.
How could a longuette be made of metal?
It might be tricky for others; however, it was nothing difficult for a rune instrument manufacturing master.
Because metals could be made into wire, which was as soft and ductile as cloth; especially that from gold and mithril. A metal called cocoon gold which originated from the depth of the crust was most suitable for being made into wire. In rune instrument manufacturing skill promotion region, there were a lot of such metals. Wire making tool could also be found here. Zhang Tie used these items to make a lot of wires from gold, mithril and cocoon gold. Zhang Tie also made a set of simple steam textile machine, using which he made rare golden, white and black metal cloths.
