Linyuan: the Dayong Survival Record of a Modern Historical Student

World view: The fictional dynasty "Dayong" has declined in national power. Internally, there are feudal vassal regimes and the exclusive power of gentry. Outside, there are "barbarians" from the north and "Baiyue" from southern Xinjiang. The system is similar to a mixture between the late Tang Dynasty and the Northern Song Dynasty. The level of science and technology is stuck in the cold weapon age, and key technologies such as movable type printing and the curved shaft plow have not yet appeared.
