In the wasteland of the apocalypse, where people are dying of hunger, young man Ming Yun breaks into a mass grave for a piece of leftover food, but uses a broken spear to dig out a rusty iron box that changes his fate - the dark gold dragon hidden token resonates with the ancestral dragon jade pendant. At the moment when the mechanical lines and bloodline are awakened, the golden ripples scare away the three evil dogs!
"Heaven's work is reopened, and the dragon hidden in the world", the ancient whisper heard when he was about to die, actually pointed to the ultimate secret buried by the "heavenly catastrophe": the rumored dragon flying in the nine heavens was actually a war machine forged by prehistoric civilization with "dragon bones as weapons and dragon souls as guides"? When the pursuers of the Burning Heaven Sect followed the dragon's energy, Mingyun, who was carrying the token, was forced to embark on the road to escape. However, at the end of the yellow sand, he met the mysterious girl Ning Mumu holding a bronze compass - she was actually the only descendant of the "Tibetan Keeper" who could decipher the dragon pattern code.
Rusty iron and dragon veins coexist, and gears symphonize with dragon scales. One is a lone wolf struggling to survive in the apocalypse, and the other is a cold girl burdened with fate. Amidst the roar of the collapse of ruins, they will uncover the truth about the mechanical dragon devouring the spiritual energy of the world. In the choice between "civilization fire" and "apocalyptic catastrophe", they will reconstruct the forgotten order! When Ming Yun raised the token and pointed it at the sky, the steel dragon skeleton that had been sleeping for eternity was slowly opening its blue pupils...
