Yaoyao loves watching Empresses in the Palace. Her favorite characters are the three sisters who are the leading ladies, along with Consort Hua. She thinks the emperor is a total scumbag. Consort Hua loved him so much, yet he killed her entire family and made sure she could never have children. Zhen Huan loved him, but he treated her as a stand-in. Shen Meizhuang loved him too, but he didn't trust her. The Empress drove a wedge between An Lingrong and Zhen Huan, turning An Lingrong against her former friends. How was that fair? If Yaoyao were in their shoes, she'd treat them all right. Who knew that the moment she opened her eyes, she'd transmigrated into the story, complete with a System? It told her that many of the consorts in palace dramas needed her love, and that she would be playing the emperor.
World 1: Empresses in the Palace. Dote on Consort Hua and the three sisters who are the leading ladies. The Empress is the villain.
World 2: Ruyi's Royal Love in the Palace. Dote on the Empress and fall for Gao Xiyue. Ruyi and Hailan are the villains.
World 3: Transmigrate to the 1970s and become the heroine. If you can give away my son, I can make sure your family has no descendants.
5. New My Fair Princess: Dote on everyone. The protagonist becomes a real princess and is the Empress's daughter, making her and the Fifth Prince siblings.
6. Scarlet Heart: Dote on Ruoxi. After the princes' succession struggle, none of the brothers will be harmed. (The male lead is Kangxi.)
In the ending, the heroine becomes a member of the Quick Transmigration Bureau and continues saving worlds. The order is not fixed.
The male leads will all be emperors, but they aren't necessarily the official romantic partners. They just do things to treat the heroine well and make her happy. I'll only write the key parts, not every single detail. For example, in Empresses in the Palace, the key events I change are Shen Meizhuang being framed, Consort Hua losing her family and being unable to have children, Zhen Huan going to Ganlu Temple, and An Lingrong being manipulated by the Empress. I won't write every single event, because that would be far too much.
