Martial Lord in Troubled Times

After three thousand and seven hundred years of chaos, the world was divided into nine vassal states, and wars lasted for three hundred years. In the north, there are the iron cavalry of the Beiming Tribe, who are watching eagerly, in the south, there are monster mountains with frequent beast tides, in the east, there are pirates running rampant, and in the west, there are alien tribes in the desert invading. The people were displaced, their bones were exposed in the wild, and there were no roosters crowing for thousands of miles. In this troubled world, a soul from another world will start a legend.
