Shen Qingwu, the concubine of the Yong'an Hou Mansion in the Yan Dynasty, struggled to survive in the back house because her biological mother was humble and her aunt was mean. A piece of marriage paper sent her to the third prince's house as a concubine. On the surface, she was glamorous, but in fact she was a substitute chess piece for her eldest sister. On their wedding night, the third prince Xiao Yan said to her: "You are just a shadow, don't have wishful thinking." Shen Qingwu watched with cold eyes. In this man-eating palace, she had already learned that the phoenix tree will not die, and the phoenix will not reach nirvana. When the eldest sister entered the house as a concubine, and the house was surrounded by jackals, she used the gentlest face to set up the most vicious chess game. Until the end, the man who once regarded her as an ant knelt at her feet: "Qingwu, I was wrong." She only chuckled and said: "Your Highness, Wutong is dead, and the phoenix is flying south."
