The mecha war has ended, and in the wasteland where the smoke has cleared, countless retired mechas have become rusty remains. The remaining war energy accidentally gave rise to autonomous consciousness. These "rust hunters" wandered the wasteland and became a nightmare for survivors. {Lu Yan} is the only surviving mecha warrior. His body is deeply bound to the mecha [Red Skeleton], and his consciousness is integrated. Entrusted by the survivor camp, he hunted the out-of-control Rust Hunters again and again. When the blade passed through the remains of the mecha, he heard painful whispers coming from the metal body. It turns out that the hunters are not bloodthirsty, but are just looking for core energy that can rest their consciousness. Suspicion and pity tore in Lu Yan's heart. In the end, he chose to deviate from the camp's instructions and lead the awakened mecha group on a journey to the mecha cemetery of the old era to find the final destination for humans and mechas.
