In the 370th year of the Daqi Dynasty, the Ziwei Star suddenly collapsed, and foreign bodies from the sky crashed into the Central Plains carrying unknown radiation. The former imperial city with red walls and black tiles was reduced to ruins overnight, and the fertile fields were turned into scorched earth. The etiquette and laws that were once regarded as the norms fell apart in the haze that blocked the sky and the strange electromagnetic storm. Born into a scholarly family, she was originally a weakling who studied mathematics in a boudoir, but she lost all her relatives in the disaster. She clutched half of her ancestral copper plate of stars and struggled to survive in the ruins of the apocalypse. She had to avoid the deformed beasts and refugees who plundered resources, while also dealing with the coercion of the remaining forces of the court. On the way, she met the former commander of the imperial army who was burdened with secrets, the stranger who possessed the remaining technology, and the mysterious young man with whom she was bound by fate. On the edge of the overthrow of civilization, love and hate, trust and betrayal, persistence and compromise are intertwined. Not only does she want to find a glimmer of hope in the apocalypse, but she also wants to uncover the truth behind the disaster. In the collision between the ancient system and extraterrestrial civilization, she must protect the remaining warmth and glimmer of humanity in her heart.
