From a modern elite to a lowly maid in a noble family, Shen Zhiwei just wants to live. She hid her astonishing wisdom and pretended to be the meekest chess piece, but she was still pushed into a deep well and silenced. Climbing back from hell, she set her sights on the most unattainable chess player - Prince Su, Xiao Jue. "Your Highness, how about I help you clear the obstacles, and you allow me a place to gain a foothold?" There are so many beauties around him, but she prefers to use her ingenuity as an edge to cut a bloody path. When each other's backs are turned over and the most dangerous secrets are shared, where will this relationship that began with exploitation lead in the end? Will we go to Qingyun together, or... Be doomed?
