On the surface, it looked like nothing had happened, and Malachi suddenly came to a halt just inches when his fist was close to blowing up the granny's head.
However, Malachi himself knew it was a different case. Initially, he had indeed come to a halt that stopped his momentum, but he hadn't come to a full stop where he wouldn't be able to move his body.
Malachi's gaze, fixed on the granny and the thing in her, made him figure out what was going on barely.
In his unique vision, Malachi saw tiny red particles emerge from the granny's slightly opened mouth and enter his system as he breathed them in.
Seeing the speed at which the particles emerged from the granny's mouth, it was inevitable for Malachi, who had not had his guard up against such a thing and was distracted when he got closer to the Monster, to have fallen for its attack.
