The fictional dynasty of Daye. It has been more than two hundred years since the founding of the country, but now the imperial power has declined. The noble family (Zhuoliu) controls the government, and the poor students (Qingliu) are weak. There are powerful enemies outside and frequent natural disasters inside. The world is like a dead game about to collapse.
