More than an hour later.
In a relatively secluded courtyard.
At this very moment.
Old Su was holding a short stick in his hand, writing the "Hundred Family Surnames" with great interest on a black oiled wooden board:
Zhao Qian Sun Li, Zhou Wu Zheng Wang....
After a while.
Snap—
Perhaps due to writing too hastily, the short stick broke with a sound.
Only then did Old Su stop, turning his head, looking at Xu Yun with bright eyes, and asked somewhat eagerly:
"Xiaowang, what is this thing called?"
Xu Yun glanced at the half-used short stick by Old Su and was glad that he had made a few extra. At the same time, he couldn't help but say:
"This thing is called... chalk."
More than an hour earlier.
After Mr. Xie had gathered all the materials, Xu Yun officially began handcrafting what was the simplest thing he had made since his travels:
Chalk.
Chalk is a very common teaching tool in later generations, and it's very easy to make.
In the 21st century.
