As soon as Lin Wei, a graduate student in the history department, opened her eyes, she became Shen Wei, the daughter of a criminal official of the Dajing Dynasty, and fell from the clouds into the turbid current of Huanyi Bureau. She has a modern mind, but she has to struggle within the strict hierarchical palace walls - washing the imperial clothes with the purification method of plant ash, relying on the logic of interest exchange to avoid conflicts, and even facing the emperor, she can't help but look up.
The seventeen-year-old new emperor Xiao Che is being overwhelmed by the powerful "subfather" Huo Lin. He pretended to be cowardly and hid his talent, but he found a memorial written by Shen Wei in the imperial garden: "Food will be distributed according to labor, not household registration." That idea that transcended the times was like a glimmer of light shining into his step-by-step chess game.
Huo Lin holds military power and is loyal to the country rather than the Young Emperor. He dislikes Shen Wei, but he doesn't know that the palace maid is using criminal investigation logic to overturn old cases and save the epidemic with knowledge about epidemic prevention. She even dares to say to him that "history books may not be true."
When the vassal king forced the palace and forged evidence of collaboration with the enemy to point to Huo Lin, Shen Wei was denounced as a "witch" and would be sacrificed to heaven, Xiao Che finally stopped pretending. He personally led the guards to break the secret passage, and she lit the firework signal - in this game of power, there is no absolute good or evil, only the growth of the emperor, the choice of the general, and the subversion of the "rules" by a soul from another world.
Under the jade steps, she was a variable; outside the palace wall, he looked at the "wallless distance" she described. Plots of power are like chess, and people's hearts are like pawns. Whose path will that light from another world illuminate in the end?
