The Apocalypse is coming, the polar night engulfs the earth, and the tide of zombies and strange creatures spawned by the radiation from the star abyss are raging around the world. In a desperate situation, Lin Feng awakened the "Machine Heart" power, which can swallow the source of mechanical transformation and transform the 200-ton heavy-duty locomotive into a mobile fortress that integrates a mecha depot, a planting cabin, and a weapons system. In order to survive, this steel behemoth set out to escape along the orbit around the star. Along the way, it continuously attracted partners such as mechanics and superpowers, and unlocked powerful abilities such as plasma cannons and mechas for coordinated operations. They not only have to resist the crazy attacks of radiation-distorted creatures, but also deal with forces such as the Silver Wings Legion and the Black Crow Organization who covet the train. As the exploration deepens, the truth of the Apocalypse Day gradually emerges - this is not a natural disaster, but a precursor to the invasion of the abyssal civilization in outer space. From surviving in desperate situations to gathering an alliance of human survivors, from passive escape to active counterattack, Lin Feng and his mecha train are not only the hope of survival in the darkness, but also the ultimate pioneer for human civilization to fight back against the abyss and welcome the dawn again.
