I Went Crazy After Dressing up as a Sickly Queen

My name is Mu Ciwan, and I dress up as the sickly queen from the mindless novel I complained about. The original owner is cannon fodder who will not survive the middle period. The whole harem is waiting to see me die quietly in the cold palace. Okay, it just so happens that my "book threading system" has just arrived, and I know the plot very well. Since this body is extremely weak, I will play with your brains. Poison? I predicted your prediction. Framed? I leave you to your own devices. The arrogance of the noble concubine, the calculations of the concubine Shu, and the pure and flawless smile of the original heroine... I will tear them apart one by one with my own hands. After all, the one who survives to the end is not necessarily the heroine.
