The old men looked at Charles, astonished.
The engineers from all over the world had never seen anyone who could build things at such a speed. Even for an alchemist, it would take days to build it, but now, in just a few seconds, the design on the paper was turned into finished products for them to inspect.
As Charles waved his hand, a lead rod ruptured soundlessly, and a column one-centimeter in length fell into Charles' hand. A piece of an iron sheet was cut from the window frame and wrapped around the lead column as a thin shell for it. Then, several dozen iron sand was put into it. Thus, the packaging was finished. An iron rod of the length of half a cigarette was held between Charles's fingers.
"Shall we begin?" Charles asked the old men who were transfixed.
"You may begin, Charles." The old man wearing a coat by the stove in the corner raised his eyes. "I cannot wait to see it."
