Li Yu's next new business venture was papermaking.
At that time, on the Bratis Continent, animal skins (mainly Parchment) and papyrus were still used for recording text.
Speaking of animal skins, although they were sturdy, durable, and even waterproof, and could be stored for a long time, their production cost was expensive.
A single sheep or cow could typically only produce one sheet of paper, and the skill required of the skinners was high as they had to remove the skin intact without any damage, while the animal skin itself must also be flawless.
Afterward, dedicated craftsmen were required to wash, depilate, scrape, and air dry the skins—a complicated process before a sheet of Parchment could be produced.
For example, the Silver Moon Church's "Silver Moon Holy Scripture" used a total of four hundred and sixty-nine sheets of Parchment, which was a considerable expense just for the paper.
The weight of the entire book was also very substantial.
