{Zhao Tiezhu}, an ordinary worker at Longcheng Steel Plant, was born with a body as strong as steel, and he never failed to carry heavy tasks and resist collisions in his daily life. A sudden resurgence of spiritual energy made the ferocious beast's lair appear underground in the steel plant. Countless ferocious beasts emerged from the ground and devoured lives. The steel plant instantly became a purgatory on earth. In the face of crisis, Zhao Tiezhu awakened his hidden talent in martial arts, and relied on his natural steel body to create his own unique skill "Iron Fist and Steel Body Technique". He led his frightened workers to build a defense line and fought against the vicious beasts time and time again to protect the steel plant that relied on them for survival. From the workshop to the underground lair, from an unknown soldier to the guardian of the Dragon City, Zhao Tiezhu used his iron fist to defeat all methods, crushing the fangs of ferocious beasts step by step, breaking through the shackles of martial arts, and finally reached the top of martial arts, creating the legend of "Martial Arts is the King".
