Duo of Destruction: Glowing One (x2!)

Duo of Destruction: Glowing One (x2!) is a daily overseer quest in Fallout Shelter.

Walkthrough
Go to the right end of the vault and take the elevator downwards (1 floor down). Go to the left side of the vault to encounter the first glowing one and some feral ghouls. Carry on by going to the left and using the elevator to go downwards again, then go to the right to find the second glowing one in the first room. Defeating it will complete the quest, however, one can continue to the right to find some more loot, including low level guns and some caps. After completing the lower levels of the vault, go back the way one came to the first elevator and go upwards to find more feral ghouls and loot.
