The core of technology was materials.
Inside Warehouse 8, Huo Yuhao tossed a chunk of ordinary hundred-refined refined iron onto the workbench, producing a dull thud.
"Look at this piece of iron."
He Caitou and the other four founding members of the Ghost squad gathered around, their faces full of confusion.
"Brother Yu, isn't this just the most basic refined iron? Other than being a little harder, there's nothing special about it," asked a curious girl named Jiang Nannan, who specialized in miniature Soul Tools.
"That's right. It's very ordinary," Huo Yuhao said calmly. "But what if we added one-thousandth of 'carbon' to it, then used special forging methods to alter its internal 'crystal phase structure'?"
"Crystal phase structure?" He Caitou froze. He had never even heard that term before.
"Simply put, it means changing the way it is arranged at a microscopic level." Huo Yuhao did not explain further; he knew they could not understand it yet. "I call it an 'alloy.' Different metals, fused together in precise proportions, can produce new materials far superior to their individual properties."
He paused, then dropped another bombshell.
"Even metal isn't necessarily required. For example, after special processing, certain plant fibers can surpass refined steel in strength and toughness while weighing only one-tenth as much. I call those 'composite materials.'"
Alloys? Composite materials?
The minds of those geniuses buzzed as though they had been struck by a heavy hammer!
Mingde Hall's materials science was still at the stage of searching for and purifying rare metals. Adding "impurities" to iron to improve its performance? Replacing metal with plant fibers? This was heresy that completely overturned everything they believed!
"Kid, you're fooling people again," Sky Dream Ice Silkworm complained in the sea of consciousness. "But I like it! Making the most badass stuff out
