Phoenix Comes to the World and Brings Disaster to the Country's Demon Queen

The most noble and proud daughter of the royal family was exiled as a slave in another country because of the crime of collaborating with the enemy and treason. Her life seemed to change from heaven to earth overnight. But later someone told her that the charge of collaborating with the enemy and treason that ruined her family was just the heart-wrenching words of a treacherous villain. It is ridiculous and sad! Even if the aloof emperor later exchanged a dozen cities for himself, he still couldn't get close to him. Dynasties have changed, but I have been wandering around in this imperial city. A little princess from the Nine Princes family has finally become a demon queen that others say will bring disaster to the country. Should I laugh at fate's trick, or should I laugh at my own absurdity!
