In a world 5,000 years in the future, the Shangyang people rule. They look different from ordinary Xiayu people, with silver hair. Everyone else belongs to the lowest class, the Xiayu. Every year, the Shangyang take ten thousand Xiayu children away as slaves. When a slave turns eighteen, they can choose their fate for the rest of their life. They have only three options: remain a slave, become a warrior, or become a Shangyang's companion and bear their children.
For the past eleven years, Jiang Yurou has been waiting every second for a chance to escape. When a Shangyang offers her a dangerous but advantageous arrangement, she agrees at once.
Can Jiang Yurou escape and return to her homeland?
