Hearing this, it wasn't Ca Ruo but Qin Yong who was the most moved, "Ah! I finally understand. Over the past month, I've been trying my hand at making the Great Black Iron Broadsword, but no matter how I tried, every time I finished, the broadsword would only be able to swing a few times before it began to chip at the edges and weaken, the method I've been using to pour in the Black Iron is all wrong and causes it to form in swirls and ripples."
"Eh?" Surprised that there was such a thing, Jian Xiao Yu nodded before saying, "It's good that you can notice such a thing. Making broadswords indeed isn't easy, many people think that because a broadsword doesn't need a sharp edge and is big and sturdy it's simple to craft, but the truth is to create such a large item the internal structure matters all the more. Which legendary broadsword is known for its sharpness? And how many are known for their durability. Hundreds of years can pass, but the sword will remain the same."
