Su Jin, a graduate student in the history department, was involved in a strange game called "Civilization Retrospection" - each copy is a fragment of history that is about to collapse. Other players mostly relied on superpowers to fight against the rules, but she found that the only way to break the situation was to restore the historical truth.
The game deliberately distorts historical details to create a dead end: the Dazexiang uprising was changed to "bewitched by demons", Su Jin relied on the research that "Chen Sheng and Wu Guang did not revolt at the same time" to decipher the way out; the Chibi battlefield became a "ghost ship formation", and she found the formation through "the true proportion of the iron cables connecting Cao's warships". The game administrator is a collection of ancient dead souls who are afraid of the truth of history being restored, and are trying their best to hunt down Su Jin.
The story profoundly explores the power of personal growth and true friendship, and shows how individuals can achieve self-worth and emotional redemption with wisdom, courage and kindness in the collision of modern rational thinking and ancient environment. At the same time, through the integration of technology (historical research) and tradition (ancient society), it celebrates the power of knowledge and the universal value that spans the ages. Ultimately, the story highlights the brilliance of human nature - the eternal theme of sticking to your heart, pursuing truth, and protecting what you love in the face of adversity.
