The Great Yong Dynasty hides a thousand-year starship inheritance. The fugitive heroine Lin Zhaozhao, as the last mechanic, makes a living by repairing ancient machinery, but she is involved in the court whirlpool because of mistaken repair of the royal family's stolen starship parts. The sinister spy male protagonist Gu Chengyuan pretends to be a businessman to approach, but he is actually investigating the secrets of the starship for the emperor. The two went from being venomous to each other to fighting side by side. The heroine used ancient crafts to repair the core of the starship, slapped the nobles who despised her in the face, solved the disasters created by foreign enemies with machinery, and even used starship radar to predict enemy invasion. In the process, the heroine's identity as a fugitive was cleared, and the hero's identity as a prince was exposed. While guarding the starship and the country, the two gained love that went in both directions, and finally used starship technology to bring Dayong into the "mechanical age."
