"So you're saying, if I learn the King Mu Sword, will my talent improve?"
"Theoretically, yes." the woman replied. "This elder mentioned that both the quality and quantity of one's swordsmanship practice equally impact the degree of talent improvement. However, Shang Fuyu may find it hard to perceive this benefit because, as the text states, the better the talent, the less significant the utility - I've also learned some swordsmanship over the years and haven't felt any improvement in my talent. This seems to be a window of opportunity for those with lesser talent."
"But in reality, if the talent is poor, learning swordsmanship will be slow, and it will be difficult to master advanced swordsmanship. Therefore, talent wouldn't improve much."
"Precisely, that's why this mechanism has remained undiscovered by the world for so long."
