blindsided by an pillar to the chest

He did not even have time for that girl’s voice to send a chill running down his spine.
With a dull roar, a stone pillar extended up from the ground and accurately slammed
straight into the center of Kamijou’s chest. Not only did it knock the breath out of him,
but it seemed to destroy his heart’s rhythm of expansion and contraction.
“Gh…bh…!?”
He frantically tried to recover his posture, but then all strength suddenly left his right
knee. The disturbance in the flow of his blood that started with his heart in the center
was belatedly spreading like a wave to each part of his body.
He just barely managed to keep one leg underneath him to avoid completely collapsing.
A dull shock struck his cheek.
Calling it a slap made it sound nice, but he had more or less been hit with the grip of the
flintlock pistol. It felt similar to being hit by the end of a hammer’s handle.
The blow shook Kamijou’s brain and he finally fell to the side onto the asphalt road
surface.
His movements looked as frail as a marionette that’s strings had been cut.
