In every dynasty across the Myriad Worlds, a massive sky screen appeared overhead, broadcasting a classroom from a later age in real time.
From emperors and ministers to farmers, artisans, merchants, and everyone in between, all heard the students in the classroom reciting in unison at the same moment: "a, o, e, i, u, v..."
It turned out they were learning how to read, along with some basic arithmetic. Apart from that, the miracle held nothing supernatural. Gradually, the emperors and ministers stopped paying much attention to it.
Those who couldn't read began learning from the methods shown in the miracle. Little by little, they learned many characters, memorized a few poems, and even figured out how to solve quadratic equations in one variable.
Then one day, a mechanical voice suddenly rang out from the miracle.
[Public literacy progress: 60%. Target reached. Beginning the next stage: middle school classes.]
The emperors, ministers, farmers, artisans, and merchants all wondered: Chemistry? Biology? What are those?
Wait, is what they said in history class true?
Theme: Study hard and improve every day.
