The Most Poisonous Princess

She is the head of the Poison Medicine Sect in the 23rd century. A silver needle can snatch people from the hands of the King of Hell. Unfortunately, she doesn't like to save people. She likes to torture them the most. Once she traveled through time, she became a mentally retarded concubine who was bullied by everyone in the Marquis. She was also bullied not only by her aunt and uncle, but also by her aunts and sisters. * When she turns into her, with gleaming eyes and sneers on her lips, you scumbags dare to seek death, then line up one by one to come to your door and let me torture you. * It was only on the way to clean up the scum that she discovered that she was not the concubine of the Marquis, but the princess's aunt who had taken away her mother's position. Not only did she take away her mother's position, but she also wanted to take away her mother's dowry. She heard that her mother left a large dowry for her, including a Dragon King's Order that could mobilize all the heroes in the world. Since it was her sister's thing, no one could touch it, and it was all left to her sister. *
