Lu Zhao, the son of a guilty minister, was exiled to the north of the late Tang Dynasty. At the beginning of the game, he was bound to the Overlord System in Troubled Times in a prison car. The system does not provide the ready-made world, but only the parts to build the world. So he started from Luming Valley, gathering refugees, establishing rules, stationing grain roads, collecting border soldiers, and training new camps. In the troubled times when feudal towns were separatist and the court was out of control, step by step he went from protecting his life to controlling counties, entering states, and commanding troops, and finally pushed his name into the world chess game.
