Possibly the longest sidequest you'll encounter in Chapter 3 of Final Fantasy VII Remake, it's nothing more than clearing out some enemies.
Pick up the quest from the Junk Dealer, who tasks you with clearing out some Lesser Drakes.
Nuisance in the Factory
Make your way through the first warehouse, making sure to break the Shinra crates. Follow the path north and into the next warehouse, where you'll have to deal with some Gorgers.
Further north you'll have to turn left, which is where you'll encounter Lesser Drakes. These monsters are weak against Wind, so use Aero to stagger them. You can get the Wind Materia from Chadley as a reward for completing Battle Intel Report #2.
If you don't yet have Aero, use other spells to bring them down to ground level, where you can wail on them with physical attacks.
Return south, then go west, where you'll have to polish off some more Gorgers in the next warehouse. Make sure you use the switch on the right of the door, so you can pick up the Fire Materia.
You'll soon come to the last warehouse, where two final Lesser Drakes await. Defeat them, and then return to Wymer to complete the quest.
Finishing this task will open up the Just Flew In from the Graveyard sidequest.
