"Don't make any noise, I'm having a live class with the ancients"
Introduction:
Lin Yan, a history student, was forced to bind the [Civilization Fire] system to broadcast modern knowledge to Qin Shihuang in parallel time and space. She was called a "witch" at the beginning, until she released Academician Yuan Longping's rice fields - a miracle of yielding thousands of kilograms per acre, which made the emperor of the ages stand up in awe and bow deeply. From then on, the achievements of mathematics, medicine, military tactics... Modern civilization turned into dimensionality reduction attacks on the ancient dynasty.
However, the popularity of live broadcasts triggered the intervention of modern countries, and the "Civilization Watch Plan" was quietly launched. When the "Militia Training Manual" was mastered by the Qin army, and when Prince Fusu came up with the idea of "people-oriented", Lin Yan discovered that there was an even colder truth hidden behind the system: this was not a gift, but a cruel experiment from a high-dimensional observer. An "accidental" technological explosion and a well-planned court conspiracy are all part of the "experiment".
Should we become a puppet on the strings of observers, or should we join hands with the entire civilization to find a way out for mankind in the countdown to "purge"? The fate of the two time and space depends on her every classroom choice.
