Spirit Magic Target Selection, Arifureta Vol 8

The human-shaped cockroaches turned to flee, but before they could run even a few paces, the light caught up to them and obliterated them instantly.
With the cockroaches gone, Hajime could once again see Shea and the others.
As far as he could tell, they were all fine.
The light reached their location, cremating all of the half-human-shaped cockroaches as well.
Shea and the others looked around in confusion as their opponents crumbled before their eyes.
A second later, they realized how strange it was that they had survived long enough to be confused in the first place.
But it wasn’t just Shea and the others that the light didn’t touch.
Neither the Grand Tree nor any of its branches were affected by the obliterating magic either.
Only the cockroaches were incinerated.
But that only confused Shea and the others more.
...
she’d used the spirit magic Cull to choose either the only creatures to be affected by her spell, or the only creatures not to be affected by her spell.
It was an annihilation spell that worked on a massive scale and spared those Yue saw fit.
