Chen Jie pushed the paper and pen towards Sun Tiechui, who said, "If we use Fire Iron, to achieve the best effect, the spear body can't be made of ordinary refined iron but rather should be made of bin iron."
"Bin iron?"
Chen Jie looked at Sun Tiechui after hearing this, as he had heard of bin iron, especially when he watched Water Margin in his past life. Wu Song's twin sacred swords were supposedly made of bin iron, and some said it was meteorite iron from outer space, but he didn't know if that was correct.
Sun Tiechui, hearing this, chuckled and said, "Hehe, Master Chen is also knowledgeable about metals?"
Chen Jie replied, "I've heard that bin iron is meteorite iron from outer space, is that correct? If so, isn't it too precious; where can we find so much bin iron?"
Sun Tiechui asked, "Who told you bin iron is meteorite iron?"
"Is it not?"
