By then, people will be able to write with bird feathers and make pencils, and there will be no need to use burnt wooden sticks as charcoal pencils to write.
Thinking of the burnt wooden stick, Meng Yuqing held his forehead. Not only was his writing slow, but it also broke easily. Sometimes he had to burn it again halfway through writing, which was very troublesome.
As for writing with a brush, he wanted to teach everyone how to write, but his calligraphy was really not good enough.
Otherwise, there are so many animals and animal hairs in this world, all of which are good materials for making brushes!
When Guangxuan turns into an animal, he sheds a lot of hair every day, which is enough to be used.
"We want these stones." Meng Yuqing collected his thoughts and said to the orc guarding the stall.
"You want them all?" The orc guarding the stall opened his eyes slightly wide and looked at Meng Yuqing as if he couldn't believe that this kind of stone was actually exchanged.

Finally found this thing.
In addition to making compost, he built the toilet because he remembered that saltpeter would accumulate in the corners of old houses and toilets in the countryside over time.

Unexpectedly, he finally didn't have to dig in the corner of the toilet.
"And this, how many do you have?" Meng Yuqing picked up the saltpeter and asked the orcs guarding the stall.
His joy was completely unconcealable, and it was obvious at a glance that he really wanted this thing.
Lian, the orc, and the orc guarding the stall were stunned and all looked at him.
He coughed twice and restrained his expression.
