In the wasteland era where AI dominates the future and classes are solidified like steel, Lin Mo, a trash man in Rusty Town, struggles to survive every day between scrapped machinery and blackmail from gangs. A fatal crisis caused him to accidentally activate the "Candle Dragon" hidden in the worn-out mobile phone in his hand - a cold and powerful mysterious AI that was far ahead of its time.
From then on, scrap metal became a magical weapon in his hands. The tattered robot can perform ancient martial arts skills that have been lost for hundreds of years; the gang's steel behemoth surrenders to him at a thought. In the underground arena, he climbed to the top despite the ridicule of the nobles, and staged the most shocking counterattack with the humblest "trash"! Wealth, fame, and power are all at your fingertips.
However, when the shadow of the mysterious organization "Deep Web" shrouded in darkness, the leader Ye Xiao took off his mask and said, "Lin Mo, it's time to return the 'Candle Dragon' you stole", unveiling the prelude to a shocking conspiracy. Lin Mo was shocked to realize that what he controlled was not a simple power, but a taboo fire that could subvert the entire AI order and ignite the war in troubled times!
From the mud of the slums to the competition on top of the world, Lin Mo held the "Candle Dragon" in his hand, using AI as his sword and scrap metal as his armor. What he wants to save is not only himself, but also this desperate world crushed by the cold code and the torrent of steel! When everything surrenders and the old order collapses, who is the real savior in troubled times?
