The Broken Heart was a mid-level Divine Power. It was an original Aragami that looked like a living creature's heart.
The Aragami was suspended in the sky above a prime material world. Along with a series of muffled sounds that sounded like thunder, its heart-like body was expanding and contracting repeatedly.
Thump!
Amidst the deafening sound, an invisible shockwave burst forth and swept in all directions.
With the Shattered Heart as the center, the clouds in the sky instantly disappeared wherever the invisible shockwave passed. Then, under the bright sunlight, the towering mountains, even if they were tens of thousands of feet tall, were instantly shattered into powder. The solid ground was turned into powder, including the steel veins inside.
Under such circumstances.
The fate of the living creatures living in this prime material world was obvious.
