Your most serious lore theory regarding why every single weapon users in the war sea know the exact same technique on the specific weapon and decided to give that one technique a name that is all the same name as everyone else.
And why do we need the blacksmith to just, extract skill out of that weapon and now we cant use it on that weapon?
They are basic techniques that everyone with a little bit of experience has heard of.
If you ever read a murim-theme story, there are some basic moves that are basically common knowledge.
About the blacksmith one…
maybe a problem of calibration?
The blacksmith slightly change the weapon to fit the technique, like bringing the center of gravity back or forth ecc???
At least those are the reasons I have given myself xD
Nah bro you can’t name that move “Spiral Rip”, John Flying Phoenix already named it after himself; and you need to use a weapon similar to his or else it’s disrespectful.
“Damn, didn’t know, prayers to you Mr Flying Phoenix”
Tbh this can be said about Mage and Fstyles too… like, why does an earth mage know how to create an instant energy-like beam of material, or why a water mage is able to perfectly shape their magic into dragon skulls or tools.
so what happened was john mcweaponbuild came down from the heavens and enlightened we humble weapon users with the knowledge of his techniques it happens to every new weapon build trust
think of like martial arts, obviously i could come up with the idea of poking my opponent’s eyes out with my two fingers, but different schools of martial arts have different techniques and such
Maybe like how some communities have developed ways of efficiently doing something, it might be effective to use that way so many people found it simultaneously
