Astropath and Matte Girl

My name is Su Yan, an astropath from New Chang'an who can read the memories of all things. My new mission is to recover a matte girl who fell from the Star Dome Tower, codenamed "Key". Officials say she can restart the world, but enemies say she can destroy everything. And I discovered that she was neither a weapon nor a god—she was my sister who died in an explosion ten years ago. Now, all the hounds in the city want to tear her apart, but she only trusts me and asks me with empty gray eyes: "Can't you hear the sound of the world breaking down?" When the pursuer's artillery fire illuminated the night sky, I took her cold hand. Orders be damned, this time, I chose to take her home.
