Shi Chengyu, a ten thousand year old student at the Galactic Federation Mecha Academy, was thrown into the meat grinding ground of the Wolf 359 galaxy right after graduation.
The Kalash dragons of the Black Dragon Empire pounced on their prey like ferocious beasts, orbital bombardments tore apart the defense lines, and a torrent of mechas rolled over the position. As the weakest corporal in the maintenance camp, he could neither operate a mecha nor fire a gun accurately. His only survival skill was to pretend to be dead.
Dodging the dragon claws in the pile of corpses, crawling out of the ruins from the explosion, this 200-pound fat man can always burst out with an astonishing desire to survive in desperate situations. When the federal "Iron Guard-V" mecha was reduced to scrap metal under the siege of the empire's "Obsidian Guard", and when the wails of his comrades were drowned in the roar of plasma cannons, Shi Chengyu could only run wildly on the scorched earth, avoiding the death that followed him.

When the steel giant collapsed in the gunfire, and when his hope of escape was crushed by the war beast, Shi Chengyu hid in the dark forest.

In this battlefield shrouded in death, the legend of the wasted maintenance soldier has just begun...
