Princess Agent

Chu Qiao was once agent 005 for the the military unit 11. After being framed and thrown into prison, she successfully escaped however she then sacrificed her life to protect the special agent unit from being bombed. She was then reincarnated into another time period, the Xia dynasty. Chu Qiao had traveled to the Xia Dynasty as an 8-year-old slave girl. Due to receiving help from Yan Xun during their escape, there fate was bound together, as Chu Qiao would then spend years helping him rebel and reconquer his land.
However, as they walked further and further down the path to their dream, they grew further apart. One reason was because of the way they dealt with things, the other was because of a rather meddlesome Zhuge Yue, who never stopped loving Chu Qiao, despite having their loyalties lie on opposite ends.
The old regime will crumble and wither away, letting the new Xia Dynasty be reborn from the ashes.
