In the Mecha Era, Everyone Holds Iron Soldiers.

The galaxy stretches endlessly, and the federal hierarchy is clearly defined. Ordinary students are uniformly issued with a rusty iron soldier body, equipped with basic propulsion components, an alloy short blade and a pneumatic cannon. Only the children of aristocratic families can apply for the two types of elite warriors and snipers. The young man Bai Xingchen possesses modification skills and uses standard iron soldiers as the basis to forge various combat armors, break through class barriers, and fight across the star sea to fight against alien beasts and monopoly legions.
