"The Beacon of Red Sand Hill" tells the story of Salan Army Captain Ahmed's counterattack at the border post. On the South Asian border in 1900, the Red Sand Post was faced with heavy pressure from the Koro Federation. Three hundred soldiers held the irrigation canal with only old single-shot rifles. In a desperate situation, Ahmed accidentally activated the "Civilization Jump System" and has since mastered weapons and technology that transcend the times.
From semi-automatic rifles to light armored vehicles, from radio communications to steel plants and destroyers, he used technology as an edge and wisdom as a shield to repel several attacks by the Koro Army, seize the Barik gem mine and Qingsha original cotton production area, and establish an industrial base in Koropolis. Faced with the political wooing of Aslan Castle and the colonial threat from the Western Continent United Company, Ahmed always held on to the initiative, guarding the land with steel and artillery fire, transforming from a border captain into the core of power controlling the east.
The story is intertwined with the cruelty of war and the transformation of civilization. Amidst the red sand and gunpowder smoke, a new era belonging to Ahmed is slowly beginning.
