During the Tianbao period, Chang'an City, at its peak, was a giant starship suspended above lies.
Li Yan, the most famous craftsman in Chang'an City, only wishes to create a clear glaze comparable to the Western Regions Glaze. However, once when he was on duty to make a phoenix hairpin for a noble concubine, he was asked to smelt a piece of "meteorite iron from outside the sky". The moment the phoenix hairpin was formed, lights all over the city turned back and cups hung in the air - Chang'an lost its weight.
This unexpected "miracle" attracted Si Tianjian, who already knew the truth. Only then did Li Yan realize that what he was standing on was not extraordinary earth, but an interstellar ark that had been sleeping for thousands of years; the "meteorite iron" he used was the final key to awakening the city. In order to seize the core, Imperial Master Si Tianjian led the entire Chang'an to ascend and escape from the Tang Dynasty, which was about to be devoured by war and abandon all the people to the ground.
The rebels came to the city, and the city above the sky began to roar and rise. Between the survival of civilization and the survival of his hometown, Li Yan grasps the core that can determine the fate of hundreds of millions. He has to make an unprecedented choice: drive this miraculous city to the sea of stars, or... Let this flying Chang'an make its final landing for the land and people under its feet?
