"Horseshoe?"
Hearing this word come out of Xu Yun's mouth.
Wang Bing was momentarily stunned:
"Is that a nuclear weapon?"
Xu Yun thought for a moment and took out a piece of paper and a pencil from his belongings.
This was a pencil he had made in his spare time not long ago, simpler than those in later generations, made of a wooden stick + a lead core.
Although the writing effect is not as clear as the industrial pencils of later generations, it suffices for emergency use.
At least in terms of efficiency and convenience, it is far superior to ink brushes.
He first drew a diagram of a horse on the paper, and then drew an arrow extending out from the horse's hoof.
Indicating an enlarged view of this area.
Then he drew a simple diagram of a horseshoe at the end of the arrow and pushed the paper in front of Wang Bing:
"Captain, this is a horseshoe, also called a horse hoof."
