Yingge, a fortress city where magic and technology intertwine, survives against all odds. Outside, the Ruinborn roam, drawn by mana. Chen Yongnian, a young engineer with a knack for fixing things, dreams of mastering magic. But mana fields and magic origin are anything but simple, and becoming a mage might take more than he’s ready to give. As whispers of danger grow in the wastelands, Yongnian’s journey into the mysteries of mana could become something much greater—or end before it begins. Acknowledgment The term "Ruinborn" is also used in the Anbennar mod for Europa Universalis IV. While this story’s Ruinborn are distinct in lore and context, the overlap in naming was unintentional. I would like to acknowledge this and pay respect to the creative spirit of that world. Author’s Note on Collaboration This novel represents a distinctive collaboration between the author and an AI co-writer. Over 99% of the content—such as Chapter 1's 3,200 words and Chapter 2's current 560 words—was generated by the AI. The author made minimal edits, often fewer than 10 words per chapter, to maintain the natural flow and clarity of the text. The author possesses solid academic and technical writing skills, which provide a strong foundation for their collaboration with the AI. However, their role is primarily that of a reader, ensuring that every major section is rewritten and refined hundreds of times until it resonates perfectly with their vision. While the AI excels in crafting vivid, engaging prose, the author’s focus on clarity and coherence ensures the story remains accessible and immersive. Through this iterative and reader-focused approach, The Hum of Yingge reflects a seamless fusion of human creativity and AI precision, delivering a narrative as polished as it is imaginative.
