Lu Chen and Su Qing awakened in the wasteland city after the "Steel Catastrophe" - Lu Chen unexpectedly acquired the "Steel Tempering" ability. Scraped mecha fragments and steel skeletons can be turned into forging materials. His body can withstand cannonballs and punch through alloy walls with one punch; Su Qing awakened the "Mechanical Martial Spirit", which can dismantle the core of mechas, control mechanical puppets, and build "steel battle armor" for Lu Chen. The two are bound by the "Steel and Arms Symbiosis" bond.
When the "Mecha Alliance" suppressed the warriors with its monopoly of energy, Lu Chen summoned the "Steel Fighting Fist" to smash the energy barriers of the alliance, allowing ordinary warriors to absorb steel spiritual energy; facing the guardian beasts of the "Abandoned Mecha Cemetery", Su Qing controlled the mechanical puppets to deflect the attack, while Lu Chen used his tempered body to resist the impact of the mecha beasts and regain the core energy.
What's even more amazing is that the stronger Lu Chen's tempered body is, the more sophisticated Su Qing's mechanical martial spirit becomes! When the leader of the alliance tried to rule the Steel City with the "ultimate mecha", Lu Chen wore the god-level armor built by Su Qing and smashed the core of the mecha with one punch: "The martial arts of the Steel City is not a tool for your monopoly!" From then on, the two used steel as blades to rise up in the wasteland city, uncovering the ancient secrets of the steel disaster and ascending to the position of "Steel Martial Lord"!
