Kidnapped into a Den of Villains to Become an Emperor and Empress

[Marriage first, love later + robbery by force + group favor + mutual redemption] [The female protagonist is a growth type, weak in the early stage, but becomes dark and powerful in the later stage] Xi Wan knew from the moment she was treated as an abandoned child that her life was nothing more than this. She was abandoned by her tribe to a border town, barely surviving. She thought she would spend her whole life in obscurity here, but one day an uninvited guest came to the town. The Nightmare Emperor who was feared by everyone set foot on the land of the small town and came to propose marriage with a betrothal gift. Xi Wan, who had not yet figured out the reason, was inexplicably abducted into the Nightmare clan, which was rumored to be full of villains, and became the queen of the Nightmare clan. She fantasized countless times that she would be tortured, used, and drained of every bit of blood there. She has no freedom and just wants to escape. She felt that this place was just a deeper abyss, but the reality slapped her hard in the face... The cold and decisive Nightmare Emperor was actually a maniac who doted on his wife without any limits. Later, she realized the reality and hugged the Nightmare Emperor Xiang Li's thigh tightly. If she couldn't escape, she would join in and became the darling of the villain's den... —— Xiang Li: "Want to escape? Why, don't you understand the thigh hug?" Xiwan: "I understand, I understand..." As long as your thighs hold you well, you can have whatever you want. Give away money, give away status, give away connections, give away equipment... It doesn't matter. * If you are not a fairy, the world background and history are imaginary, so don't pay attention to them.
