Void Shatter/Fissure, Arifureta Vol 6

She spoke the name a single spell.
“Void Shatter.” Space itself splintered. Everything looked like it was being seen through a cracked mirror.
Thousands of lines streaked through the sky, and where those lines joined, the world blurred.
Any Ash Dragon caught along those lines was ripped apart.
Blood rained from the sky as the dragons were shredded with a sickening ripping noise.
This was her new spatial spell, Void Shatter. It split space along lines she defined, mercilessly cutting anything caught along them.
Because it warped space itself, there was no defending against it. Thirty more Ash Dragons joined the list of casualties.
...
Void Fissure!” The space around Yue began to warp.
It was followed by a low rumbling, which sounded like the screams of the planet itself.
Yue knew what kind of spell Freid had cast, and instantly switched to defense.
Void Fissure’s scope was too large for her to avoid. Normal magic held no chance of defending against it, either.
She got her spatial barrier up just in time to catch the explosions caused by Freid’s Void Fissure.
They weren’t normal explosions. It was as if space itself had ruptured.
Freid’s remaining Ash Dragons and the monsters on the ground were wiped out instantly, the ground underneath Yue was torn apart, and the clouds above her were shredded to bits.
Void Fissure was a spell that forcibly contracted then rapidly expanded space in a certain area. The resulting shockwaves caused explosions that were unblockable by normal means.
