Uranala Rouze returned with the hatred of her previous life, cleverly attracted the attention of Prince Yong Yinzhen with a song "Oll and Heron Forgot the Machine", and stepped into Prince Yong's Mansion step by step. On the surface, she is gentle and gentle, but in fact she is meticulous and has every plan. She not only wants to avenge her concubine Yi who betrayed and hurt her, but also needs to gain a foothold in the turbulent back house. In the house, Yi Xiu is hiding poisonous plans and pressing forward step by step. Nian Shilan is proud of his favor and shows his sharpness, and all forces are intertwined and fighting. Rou Ze relied on wisdom and ruthlessness to cover up others' ears and eyes by copying scriptures in Buddhist halls, and to remove obstacles with the help of others. She dealt with suspicions and calculations, not only to deal with Yinzhen's scrutiny and temptation, but also to resolve endless crises. From the cautious layout when she first entered the palace to gradually assuming power, she used gentleness as a mask and ruthlessness as a sharp blade. In the whirlpool of love and hatred, she vowed to rewrite the tragedy of her previous life, take control of her own destiny, and perform a drama about revenge, survival and power in the back house.
