In the blink of an eye, Lin Yi had completed a drawing and handed it over to the person opposite him.
Lin Yi is no longer using a brush to draw, but a pencil specially customized for him.
As for whether the "lead" in the pencil is actually lead, that can be outright denied.
It is not lead that is used inside, but charred wood.
After all, lead at this time cannot be refined.
At least not to the extent of the current level of technology.
But charcoal can also be used just as well, and the effect is quite satisfactory.
The advent of this item also caused quite a stir.
When they first saw this item, they were incredibly shocked.
Never did they imagine that ordinary charcoal could have such a use.
This too left them astounded.
Of course, talking about this now is somewhat off-topic.
Let's just say that at this moment, the craftsman holding the blueprint drawn by Lin Yi is momentarily stunned on the spot.
"Sir, is this the repeating firearm you mentioned?"
