Li Ming had Zhang Huaiyuan watching as well; it was just another channel.
Zhang Huaiyuan added, "But, at Professor Xia's, there should be quite a few."
"Hmm?" Li Ming was slightly taken aback and turned his head, "How do you know?"
Zhang Huaiyuan gave an embarrassed smile, "I know the preferences of all the Professors, or rather, we ordinary students all know, just in case we run into them so it's easier to strike up a conversation."
Zhang Huaiyuan further explained, "Professor Xia is a well-known Mechanical Master; many Advanced Life Forms seek his help to craft weapons."
"The materials are naturally provided by them, and many of the core components of special weapons are Mother Ore grade materials."
Li Ming was contemplative, realizing that many powerful weapons were difficult to produce on assembly lines.
Take his Crystal Alloy Ion Longsword, for instance; the main material was Crystal Alloy, a composite of various materials.
