The cherry blossoms fall into the pond, and the ruins offer sacrifices to the sun. Everyone is a piece of flawless jade, and what awaits them is falling into the endless mortal world. In this world, who decides what is right and wrong? Who can choose between love and hate? She appeared in front of him with scars all over her body, destroying his original world. Who could escape? This is an absolutely heart-wrenching novel that rejects Mary Sues. It tells the story about what happened in another dimension of the world, the "Rust Realm". The Xu Realm is a hidden space, and all things and laws in the world are controlled by the Xu Realm. There is no difference between people in the market world and ordinary people, but the fate they carry makes their love and hatred destined to be the last song.
