Shen Qingdai opened her eyes and found that she had become the concubine of the Hou Mansion and was being held in worship. The groom is King Jing Wei Zheng, the legendary living king of hell who kills without blinking an eye. Now he is lying on the bed with only one breath left. The prince asked her to marry her as a spy, the queen was waiting for her to make a fool of herself, and everyone in the house was laughing. Shen Qingdai looked at the festering wounds on Wei Zheng's body and frowned. If it's infected, it needs to be debrided. She took out her pocket knife and roasted it in the candlelight. My lord, please bear with me. Wei Zheng opened his eyes and saw his new wife slashing his chest with a knife. Later, the entire capital knew that Princess Jing knew how to kill people. The prince wanted to poison Wei Zheng, so she dissected the body overnight to find out the source of the poison. The queen wanted to frame her for adultery, so she dismantled all the false evidence in front of everyone in the court. The emperor put an unsolved case in front of her and gave her seven days to solve it. Shen Qingdai opened the file and smiled. What a coincidence, this was what she did in her previous life.
