In the world, there were gods who obeyed the rules, whether good or evil. But there were also evil gods who defied the rules. When a traverser was confronted by the rules that he could never conform to, the resulting collision marks the beginning of the story of an evil god… This is the story of a good man who transformed into a great jellyfish, then traversed his world to arrive at a world of swords and magic. His journey of searching and exploring eventually led to him remaking nature and changing the world.
The research for ink and ink stone was carried out smoothly, but paper making technology wasn't.
Wor accidentally made papers that couldn't go well with a feather brush. If there was a type of paper that could only be used with a writing brush, and that required many other combinations and writing speeds, and was comparably slower, one shouldn't hope that it would be popular and common. Because writing was a tool, not an art.
Thus, efficiency was more important, as compared to mere appearance. But, to invent a paper that a feather brush could write smoothly on, and ink would smudge on, well, that's easier said than done!
