When history is spoiled, rebels emerge.
Chu Yan, a graduate student in the history department, traveled through the late Qin Dynasty and became an alchemist who tested poisons for Qin Shihuang. Just as they were dying, the sky cracked, and a huge curtain called the "Sky Curtain" descended, revealing the bloody future of the death of the second generation of Qin Dynasty and the conflict between Chu and Han.
With knowledge beyond his time, Chu Yan became the only anomaly in the empire who could decipher the "Sky Curtain". His attempt to guide history toward a less painful fork in the road triggered the most terrifying backlash in history—the historical revisionists.
They are strong men whose fate has been revealed: Zhao Gao who is unwilling to be killed, Sima Yi who glimpses the bloody night of Gaopingling, Wu Zhao who predicts the end of the Queen... They do not want to be footnotes in the history books, and they do not hesitate to use the entire era as a chess game and hundreds of millions of living beings as bargaining chips, vowing to tear up the established script.
From the embers of the Qin Fire to the beacon smoke of Chibi, and then to the shocking changes in Xuanwu, Chu Yan holds the mysterious bronze mirror in his hand and struggles to move forward in the history of the drama. Every time he intervened in good faith, it led to more crazy counterattacks from the revisionists and more bizarre time and space turbulence. The butterfly effect of history will eventually become a storm that swallows everything.
When the huge waves of the three eras converged and reality and history eroded each other, Chu Yan was forced to face the source of all chaos, which was also the ultimate choice:
Should he erase all changes with his own hands and return everything to the origin of "official history"; or should he accept this new world with an uncertain future that was jointly shaped by him and the revisers?
