The Tianmu National War system has arrived, linking ancient and modern times. Each country selects time travelers to go to the modern world for seven days to learn new knowledge. The ancient war determines survival in this world, and failure means both parties will perish. Fusu, who had revived the Qin Dynasty for twenty years, was unexpectedly selected. He gave up studying hard and indulged in the fireworks and prosperity of the world. Everyone in the world scolded him for being a fool and ruining the Qin Dynasty. Little did they know that he had already stabilized the government and prepared for a prosperous era. He was waiting to return to crush all nations and rewrite the fate of the country in ancient and modern times.
