History is not a foregone conclusion, but a river formed by hundreds of millions of "what ifs".
Chen Qing, an ordinary history graduate student, discovered to his horror one day that he could resonate with the raging historical obsession on the Internet - when countless people empathized with "if Qin Shihuang had not been assassinated", the huge collective thought actually catalyzed him into a life form that spans dimensions: [Yanhuang].
He is not alone. He is the "but" condensed in time and space from all unwillingness, all questioning, and all collective wishes to protect Chinese civilization.
The mission is heavy: to swim upstream and dive into key nodes of history, so that civilization can avoid hidden reefs and continue healthily. And his first mission was to return to the Xianyang Palace in 227 BC and the shocking moment when Jing Ke presented the map.
But the waters of history are deeper and muddier than he imagined.
The history book he thought: The picture is poor and the dagger is visible, and the King of Qin surrounds the pillar.
The truth he faced: the blade was hidden in the axis, the palace guards responded internally, and the poisonous schemes were intertwined. Under the history books, there are surging undercurrents.
The power he relies on: not invincible powers, but an innate "sympathy" for the historical context, and an almost instinctive deep understanding of Chinese artifacts, characters, and techniques - that is the echo of civilization genes in the collective consciousness.
And as the first "historical landmark" was lit up, he gradually realized that there seemed to be an older secret sleeping underground in China. The undercurrent of fire in Lishan Mountain, the whispers outside the ice wall... He may have changed more than just the past.
