Moyong Baek was assembling a fan while looking at the blueprints laid out on the desk.
The components were made of steel, strong enough to withstand most swords, and consisted of a long, box-like frame, several thick steel needles, and small beads.
Although the blueprints were drawn by Moyong Baek himself, all the steel parts were crafted by Yongdu Steel Workshop.
This was the fifth time he had commissioned the production of this military weapon after four previous failures.
It was true that Yongdu Steel Workshop's skills had improved day by day, but they had never made a fan out of steel, so there was no choice but to proceed cautiously.
As he assembled the first steel needle at the bottom of the frame, Moyong Baek smiled slightly.
"Smooth," he thought.
Thanks to the previous failures, the quality of the components this time was good.
Without looking at the blueprints, he inserted the steel parts one by one, covering them with thick paper and securing them with a blunt, thin needle, transforming it into a steel fan.
Later, he planned to paint it white and name it Baekseon, after himself.
It was indeed strange for a physician to carry a military weapon.
