I'm Just a Useless Part

If you were born to be a consumable of this era, would you accept your fate? 17-Year-old Ian lives in the golden age of magic, but he is just a speck of dust that has been crushed by the golden age. Unable to implant the "needle core" that is the core of spellcasting, he thought that his limit was to spend his whole life in an antique shop, until batches of "useless" civilians began to disappear, and a whirlpool began to swim in the darkness. The last words that my father died in exchange for were not a treasure map, but an escape route map. The end point of the map is a legendary land without industrial pollution, and the starting point is that he must take everyone who is unwilling to be a battery within thirty days and get out of the imperial capital alive. This is a race between the powerless and the entire era. The only thing he could bet on was that those high-ranking figures wouldn't care about a few grains of dust missing from their feet.
