Sang Chaqing, a taboo profession "Rust Whisperer" who was exiled from the mainland, lived by picking up rags in Broken Ridge, just to find out the truth about his mother being burned to death by the parliament. He can understand metal whispers and awaken the remains of mechas from the old era, but because his identity is exposed, he can only live like a wild dog in the wilderness. In an accident, he rescued Lin Yuan, a seriously injured female engineer, and unexpectedly discovered the heart core runes left by his mother. He also learned that the most powerful power of the old era was hidden in his body - the heart of ancient weapons! This is the only key to activate the Final Colossus, and it is also the real reason why the Council is hunting him down! For revenge and protection, Sang Chaqing no longer holds back! The power of Rusty Whisper awakens, the scrap metal reorganizes the mecha, and the machine gun tower sweeps across the hunting team! "You burned my mother and regarded me as a monster. From today on, I will use rust as fire to burn the entire parliament!" When the Heart of Ancient Mechanics completely erupted, all the mechas in the rusty wasteland woke up. He stood on the top of the wreckage, overlooking the entire continent: "I, Sang Chaqing, am the king of the old era!" The rust fire burned out the darkness, and the mechas dominated the apocalypse!
