Chen Xin transmigrates to this vast world and becomes an illegitimate son of the Chen family. After Chen Tian, the Great Ying Empire’s God of War and a prince of a different surname, is accused of colluding with the Xiongnu to rebel, he is ambushed and killed by the Great Wall garrison. The Chen estate is confiscated, and Chen Xin is cruelly exiled to build the Great Wall on the northern grasslands of Great Ying.

He summons the Trapped Camp, White Horse Volunteers, infantry in heavy armor, Iron Pagoda Cavalry, Zhuge repeating crossbows, and Guan Ning Iron Cavalry. In the north, they crush a hundred thousand Great Wall guards, then take command of the Great Wall’s natural fortress! March north, conquer the east, pacify the south, and defend the west! From a small state to an empire, from an empire to a dynasty, from a dynasty to an imperial dynasty, and from an imperial dynasty to a divine dynasty! Beneath all Heaven, there is no land that is not the king’s; to the farthest shores, there are none who are not his subjects! I will carve out an enormous realm!
