History's Crossroads: The Sky Screen Descends

High above, a vast screen silently unfurled. It had no owner and no agenda, simply playing the judgments and mockery that later generations had made about history.

When Qin Shi Huang saw the verdict “The tyrannical Qin dynasty fell in its second generation,” when Li Shimin witnessed the age-old controversy over the Xuanwu Gate Incident, when Zhu Yuanzhang heard the fateful saying “The emperor guards the nation's gates; the ruler dies for his country”... history's script was thrown into disarray.

But this was no simple preview of the future. The sky screen's broadcast of Basic Laws of Physics was revered as a heavenly text by Mohist disciples. The World Map ignited explorers' ambitions, while A Brief History of Civil Rights planted quiet sparks in the hearts of scholars.

This was a historical experiment spanning countless dynasties, a stress test of civilization in the face of an explosion of knowledge. There was no savior, only people in every era, making their own choices amid shock and struggle, together tracing history's infinite possibilities.
