The master left behind a mystery after his death. There was only one ring. I didn't know where my biological father was. Before I could check it out, I received a special task. Although I had known for a long time that Zhiwei belonged to Emperor An Guo, I didn't expect that Zhiwei's owner was already the fifth prince An Chen. He taught me chess, calligraphy, painting, conspiracy, and even tricks. He also taught Fangzhongshu. The new mission turned out to be to go to Qi State to be a spy. The best way for a woman to collect information is to go to a brothel. Because she was unwilling to be bullied by others and could not kill people, she could only protect herself with her own strength. She became an oiran step by step, but met the person who was willing to give everything for him. I have known for a long time that he is the third prince of the Qi Kingdom. He treats me as a confidant, and I only collect some information, and we are fine with each other. An Chen once told me before that the answer to the mystery of my life experience can be found in Qi State, so I started investigating when I had nothing to do. The master only left me a ring, and before I left, An Chen once told me that my mother's name is: Blood Butterfly. Just where is my path?
