Villain, the Yandere Empress's Rebellion Development Plan

[Sick Love + Pure Bai + Western Fantasy + Slow Drama | Double Yandere Warning] ———— Elena traveled through time and became a sick man who was about to die soon. In order to survive, she signed a contract with the devil - the price was the sacrifice of happiness and the destruction of her family. For safety, she coaxed the escaped elf girl Muika into the mercenary group, using herself as bait to lend her strange powers; For the sake of strength, she kidnapped Selene, an innocent descendant of the ancient country, in the bloody fire of the green-skinned city, forced a master-slave contract, and forged her into a murderous weapon with her own hands. She thought she was a hunter. But she didn't know that the elf Muika, known as the "Seed of Destruction", had already fallen when she held her hand. One day in the future, she will trick Elena into the depths of the Sacred Tree of Agaea, and she will lean over and wipe away the tears from the corners of her eyes every day: "Elena, I can't leave anymore." As for Selene, who was raised as a weapon, the first thing she did after awakening her bloodline and regaining the throne was to reverse the contract. She hid Elena in her bedroom, "repaid" her with a hundredfold means, and chuckled in her ear every night: "Master Elena, what you said - 'Come with me to the happy end of the story'... Is it all a lie?" Elena, with gray eyes, was trembling and huddled in the corner of the bed, listening to the approaching voices, the brand on her neck was hot. In the future, what awaits her will be never-ending "happiness". ———— (This book is also called: Survival Rules for the Noble and Despicable) (Also, I will write extras.)
