The Great Nirvana Cataclysm ended a hundred years ago. All prosperity was destroyed. The revival of spiritual energy and modern technology collapsed simultaneously. In troubled times, city-states were divided and plundered in the wilderness. Su Huai, a low-class refugee, had no power and was bullied. The desperate situation awakened the study to trace its origins and unlock lost farmers from ancient remnants. The inheritance of countless ancient methods such as farming, medicine, and blacksmithing has attracted city-states from all over the world to covet and suppress him. However, he gathered the refugees and took root in the wasteland. He used ancient skills to cultivate fields, refine medicine, and forge soldiers to control floods. In the devastated wasteland, he built a stable and civilized home to protect thousands of people.
