"I made some gadgets before, you may not know, I have a mecha and some weapons, which I temporarily left on an island during the escape. I've already sent someone to retrieve them, and they should be sent back soon."
Li Ming explained calmly.
Isus nodded as if suddenly realizing something, then thoughtfully said, "I'm not very knowledgeable about metallurgy, but isn't metal purification and smelting going to produce some sort of slag?"
"Your Highness really doesn't understand." Li Ming explained with a smile, "In metallurgy, there's no such thing as waste material; it's just alloy whose structure has been altered. It only needs re-melting to be turned back into usable metal."
"Slag is only produced at the time of purifying raw metal ores."
"I see." Isus laughed, "It seems I've made a fool of myself."
