In the fifteenth year of the Rust Era, four monuments to civilization stood under the hazy sky. The steel dome of the Mecha City imprisons the Immortal Cultivator's Nascent Soul, and the blood of the Superpower pours out the Summoner's Ancient God Totem. When Lin Feng awakened the power of metal manipulation in the scrapyard, and Su Yao brought out the bloody prophecy fragments from the sword tomb, the two young people who were marked by fate with dimensional scars were forced to face the bloody truth - the so-called doomsday is just a time experiment that lasted 380 times.
They walked through the gear execution ground of Cyber Fengdu, passed through the reincarnation mirror of the Quantum Temple, and caught between the Mechanical Buddha and the Ancient God of the Abyss, they uncovered the shocking secret of the immortality of the founders of the four sects. When the giant palm of the interdimensional observer tore open the sky, Lin Feng melted the core of the mecha into a god-killing blade, and Su Yao ignited the fire of civilization with her natal sword spirit. This is the story of a boy from the wasteland and an orphan girl from a fairy gate. It is the swansong of the rusty gears and the frosty sword energy. It is also the last battle cry of all the souls trapped in the cage of time to the universe.
