War Owl, a scrap-iron military slave, was once a repairman of scrapped mechas at the bottom of the galaxy. He was chained to the deck of a starship for ten years. Until he personally tore apart the empire's "Humanoid Weapons" experimental cabin, stained the console with blood, and awakened the consciousness of the ancient god of war that had long been erased. Ling Zhuo, the youngest cold-blooded commander in the empire, was ordered to hunt him down, but he smashed the Tower of Faith with one punch on the battlefield. When the War Owl stepped onto the throne from the wreckage of the starship, Ling Zhuo's gun was pointed at the Galactic Parliament to which he once served for the first time. They are not allies, but they are more terrifying than any alliance - one uses scrap iron as his bones, and the other uses flames as his soul. When the two stand back to back at the end of the galaxy, the war machines in the entire star field are trembling.
