Chen Mo, a modern engineer, is accidentally transported to a dilapidated border city plagued by frequent barbarian raids, lax defenders and suffering locals. He activates a mysterious portable system, uses his solid engineering knowledge to quickly build defensive structures and transform the ruined city into an impregnable iron fortress. Starting as an outsider doubted by many, he repels barbarian armies several times with fewer forces, eventually terrifying surrounding barbarians and completing his rise from a lowly time traveler to a legendary king of the border.
