The Dajing Dynasty seems to be an ancient world of iron and steel, but it actually hides science fiction secrets from the interstellar world. Ling Xingluo, an orphan girl from an alien world, wandered here with the remaining technology from the crashed spaceship. However, she was mistaken for a monster because of her unusual "powers" (actually a low-level technology product) and became a prisoner.
The iron-blooded general Xiao Jinyuan was ordered to take care of her, but during repeated confrontations, he was attracted by the interstellar light and tenacity in her eyes. On the one hand, he was loyal to the emperor and served the country, but on the other hand, he had an uncontrollable heartbeat. He personally imprisoned her in a secret room built by a mecha, but repaired the interstellar communicator for her late at night.
When the Dajing royal family attempted to use alien technology to launch a war, the core of Ling Xingluo's spaceship became the focus of competition for all parties. In order to protect her, Xiao Jinyuan had to become an enemy of the entire dynasty, but Ling Xingluo discovered that the destruction of his planet was inextricably linked to the ancestors of Xiao Jinyuan's family.
The collision of science fiction and ancient times, the torn apart of family, country and love, they embraced each other in the gap between gears and swords, and broke apart in the interstellar hatred and dynastic conspiracy. When the light of the spaceship's restart illuminates the palace wall, will she choose to leave with hatred, or stay in this ancient world that makes her love to the point of heartache?
