The Interstellar Sinner Was Exiled to the North by Her Father at the Beginning.

Su Changge, the empire's greatest genius and interstellar sinner, was still thinking about how to blow up the Inquisition before he was pushed into a rift in time and space. When she opened her eyes and woke up, she found that she had transformed into the most disliked ninth princess of the Liang Dynasty. At the beginning, she was demoted to the ice-covered north by an imperial edict from the old emperor, and even the funeral was kept simple. The same empire, the same name, two lives. While the royal family in the palace were still fighting for a throne, Su Changge had already used interstellar technology to build the first basalt blast furnace in the north and smelt the first furnace of Hongwu Steel. When the neighboring country's cavalry pressed on the border and the beam was in danger, the fifth prince broke into tears: "As long as I sacrifice my nine sisters to the enemy, it will be enough to retreat!" Su Changge stepped on the iron boots and smashed the dragon steps, and appeared in the court wearing a homemade exoskeleton armor—— "Use your sister to retreat the army?" She picked up the alloy sword and pointed it at the civil and military officials of the Manchu Dynasty. "I think this dragon chair should have a different name." She once judged a galaxy with one hand, and now, it is her turn to judge this decadent dynasty.
