Chang An in the Tang Dynasty of China (618-907): The demon star is passing through the sky, clamity is about to befall the Tang Dynasty - because of a woman.

The story is set in early Tang Dynasty, after the Xuanwu Gate Incident, in which Li Shimin the prince of Qin, killed the crown prince and usurped the throne soon after. It is under such background that our female protagonist set out to discard her former identities and seek revenge against the most powerful man in her world.

Note: This story was put on hiatus on March 2016. The author's contract with SUMMERZOO ended in Sept 2017 and she has since founded her own studio. Until she is able to get the rights back to Chang Ge Xing (and Zi Bu Yu), she won't continue publishing it, but she has promised and reassured that it lives on somehow.
