My name is Lin Fan. I am a survivor at the bottom of the shelter. I am destined to live an ordinary and humiliating life. When the "Reaper", which symbolizes destruction, arrives, the Earth Alliance forces are retreating steadily. In desperation, the officials finally noticed the young man who walked out of the ruins and his weird mecha that carried the wisdom of the old era. Lin Fan, a former scavenger, piloted his mecha from guarding a ruin to heading into the final battlefield for the survival of the entire civilization. This is not only a war, but also a mortal. It is proved by human beings that "a mortal's body can also be compared with the gods"...
