Years ago.
The young Zuo Xingyun and Xun Lu met in a dilapidated orphanage, where, after discovering the staff secretly trafficking children, they planned an escape with others.
A group of naive kids, they climbed over the rusty iron fence, thinking they could escape to freedom, but in the end, they were discovered, and only a few managed to get away.
The outside world was not any brighter than the orphanage, instead, it was even darker.
They left the orphanage to evade the traffickers, yet they were targeted by traffickers once outside.
They were taken to strange domains, sold off to different places, and thus lost touch with one another.
Thinking they would never meet again, Xun Lu, now twelve, went with her adoptive parents to labor in Haicheng and unexpectedly encountered Zuo Xingyun.
