Calculating the Future: a Math Teacher's Adventure Through Time Travel

Notice! This novel is quite brain-intensive to read and involves a lot of mathematical knowledge. However, I have tried my best to explain it to you. Readers with a certain mathematical foundation are required to understand it. An ordinary mathematics teacher, by chance, traveled back to the Chongzhen period of the Ming Dynasty. Using his mathematical theory and modern wisdom, can he save the Ming Dynasty from its decline? From simple daily life to complex country and country, how can we save a declining dynasty? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
