Cheng Feng traveled through time and became a blind teacher, only to find that his student was the prince Li Chengqian who was demoted to a commoner!
"Teacher, my father wants to destroy me..."
"What are you afraid of? I will teach you how to be a scientific emperor!"
While others still care, his school has already taught mathematics, physics and chemistry;
When an aristocratic family monopolized government affairs, he led his students to reform the imperial examination;
When the Turkic cavalry went south, his invention of gunpowder made the Tang Dynasty stand on top of the world!
Changsun Wuji: "If we don't get rid of this son, the family will be in danger!"
Li Shimin: "Cheng Aiqing, how about giving you half of my country?"
Many years later, when Li Chengqian created the "Zhenguan Age", Cheng Feng smiled slightly deep in the Qinling Mountains:
"It's time to go meet Li Bai and Du Fu..."
(Small theater)
Li Chengqian: "Teacher, these Arabic numerals are so easy to use!"
Cheng Feng: "This is called mathematics. I also learned calculus by the way."
Wu Zetian (eavesdropping): "Sir, do you still accept female disciples?"
Cheng Feng (alert): "Is this historical line crooked?"
