On the ruins of the nuclear war, the warlord Hossen, with Steel Town as the center, ruled tyrannically under the banner of "restoring order" and turned the survivors into slaves. Construction engineer Chen Panshi was captured into the city and forced to design fortifications. He is calm and pragmatic, submissive on the surface, but secretly uses his professional knowledge to draw a blueprint for the new city. Using reinforced concrete and abandoned machinery in the wasteland, he organized workers to secretly build underground shelters, repair hydropower stations, and transform farmland. As his power grew, Chen Panshi launched an uprising to overthrow the tyranny and transform Steel Town into a true City of Hope - a solid fortress rising from the wasteland.
