Shen Zhaoning, a high school senior humanities student, transmigrates into the most pathetic Empress. The late Empress was her own older sister, a suspected transmigrator who died suddenly after pushing for universal equality. Noble Consort Su Wanqing bears a seven-tenths resemblance to the late Empress and makes things difficult everywhere; she is merely a substitute for a substitute. There is also a secret in the palace: anyone who understands math, physics, or chemistry cannot live past three months. To save her life, she takes illiteracy all the way—when the Noble Consort recites poetry she plays dumb, when the Emperor talks about romance she plays asleep, and when the Empress Dowager urges her to rebel she sneaks out of the palace. Until the Noble Consort leads personal troops with black gunpowder to blast open the palace gates in rebellion, and the mute dark guard who played cards with her removes his mask: Don't be afraid, I replaced her gunpowder formula with dud shells long ago. Shen Zhaoning faints on the spot, just how many modern people are hidden in the palace?
