Sold at the age of five and trapped in a brothel, Lin Wei's fate seemed to have been sealed. But she didn't believe in fate - she secretly learned literacy and worked hard at arithmetic. She wanted to earn a future for herself in the mud. When Xiao Jue, the investigative prince, sneaks into Yihonglou, he becomes her only hope of leaving the country.

From the bird in the cage to the chess player, from Lin Wei to Lu Qingci, she paved this road with wisdom and established herself with character. Let's see how she, as a woman, settles the world's misunderstandings and walks out on her own ten-thousand-mile future.
