On the Day of the Fall from Heaven, the entire world was forced to fly planes to survive, and everyone got a broken plane to kill monsters, upgrade, and repair. Lu Ming, a repair shop apprentice, discovered that he had cleared this game ten years ago. While others flew broken planes to run for their lives, he picked up an unwanted trainer aircraft and, relying on his walkthrough, evolved it into the entire server's only transformable mecha. Aerial combat makes it a fighter jet, landing turns it into a Gundam, killing monsters like running a dungeon. Until the server-wide announcement popped up: Chief Player 001, server-wide bounty. He just wanted to hunker down and survive, so why did the whole server want to kill him?
