I died on the night my husband took his concubine, one corpse and two lives, and I soaked in the bottom of the well for seven days. When I opened my eyes again, I was fifteen years old again. My stepmother was holding the bowl of bird's nests and calling me "Wu'er" with a smile. Shen Qingwu was the legitimate daughter of the Minister of Rites of the Dayin Dynasty. She was docile, frail, and virtuous - this was the evaluation of her by the whole capital, and it was also a reminder of her previous life. In this life, she was a lady during the day, and became a teacher of the mad woman at night, learning swords, poisons, and human hearts. She smiled and called her stepmother "aunt", smiled and "recruited virtuous women" for her husband, and smiled and ran into the arms of noble people during the hair-raising ceremony - every step was a game, every tear was a calculation, until she met Pei Zhao. The rumored Marquis of Jingbei who burned half of his face, the illegitimate son who held 300,000 soldiers but wore a mask all year round. He saw through her trick of holding her breath for a quarter of an hour, handed over the tiger charm and said "Do you want to cooperate?" She wanted the throne to depose Prince Ning, and he wanted the throne to overthrow this decadent dynasty. They were allies, accomplices, two men crawling out of hell, covered in blood. "You can cry," he said, "You don't have to be a pawn in front of me." She realized that it was more exciting to have someone on the road to revenge than to climb to the top alone. When Prince Ning knelt down and begged her to turn back, when the emperor passed away and the palace door opened wide, when he said, "Our meeting is what I have been waiting for for three years" - she finally understood that in this life, there was someone to jump with her and climb out of the unfilled well in her previous life. From the bottom of the well to the phoenix seat, from the chess pieces to the chess players. In this life, she will not be a virtuous concubine, but a phoenix.
