Hrakka's eyes went wide with everyone else. They had never seen such a shocking thing in their lives.
Did time just… stop?
Ryu's coughing was the only thing that brought them back to reality. He had just suffered an injury not of the body, but of the soul.
Manipulating time was one thing; manipulating the time of another person was another matter entirely. If Ryu had tried this against Silent Quibus, let alone an injury, his soul would have shattered and he would have directly died.
To put this matter into perspective, just cutting one of Silent Quibus' Lines of Fate took practically everything out of him. He ended up half dead cutting nine of them.
Freezing someone in time was like cutting them off from all of their Fate. It was only for an instant, a brief flash in the pan, but one could still imagine the level of pressure that had to be endured when this was done.
