Fighting in the Palace and in the House, You Have a Brain! 9.5 Points or More!

I want to read a book similar to "Zhaohua Rebellion". 9.5 Or above! The heroine is a concubine who slowly rises from a low position or slowly rises up in the palace. She is sober and does not love the emperor/prince. She is ambitious and ruthless. She must avenge her revenge. She has brains and brains! Pretend to be a pig to eat
