The Empire Avenue ran from the south to the north. It was a great avenue built by countless craftsmen and master dwarves over the centuries in the steel arms empire. It was also a guarantee for connecting the major cities.
It was not only connected to the major border passes, but also to the major trading ports. It was like a main blood vessel that maintained the flow of the Empire’s blood.
The Great Dao was costly. Every few dozen kilometers, there would be a large-scale relay station that could provide food, accommodation, and supplies for traveling merchants. Of course... The price would be slightly higher.
To the soldiers, these relay stations were all free, but no relay station could satisfy the supply of tens of thousands of soldiers. Therefore, most of the supplies were brought by the soldiers themselves. The relay station could at most provide hot water for tens of thousands of people, which was very powerful.
