Morning.
Inside the factory's large, empty building.
A group of children stood before Lu Yuan, with several private tutors beside them.
Lu Yuan was personally teaching them a jingle.
A-B-C-D-E-F-G~
It was catchy, and they could basically memorize the whole thing in a short while.
He wanted them to learn as much as they could.
After he finished teaching, Lu Yuan led his people away. By now, the machine was finally ready.
To be precise, this thing was a Spirit Stone photocopier.
In truth, the movable type printing technology of the Ming Dynasty was the absolute pinnacle of any feudal dynasty.
It was like the old saying goes: if not for this, three of the Four Great Classical Novels would not have been published during the Ming Dynasty.
But this technology had a big problem.
First, it was currently the late Yuan and early Ming period, so the technology wasn't yet at its peak.
The true peak would come in the mid-to-late Ming Dynasty.
