As for what he did to that pen, he simply speeded up the flow of time around it, causing the speed and power to increase greatly.
This was why the boy had been knocked out so easily, even though he was only hit by the butt of the pen.
During the past week, he had tremendously developed his time element through intense training and practice.
Controlling the power was a little difficult at the start, but he eventually got the hang of it, learning how to use it freely.
Unlike the first time when he could only use time freeze in a small, enclosed space, his range had greatly expanded.
Although it wasn't as large as he wanted yet, freezing time in somewhere like this alley was now quite easy for him, which made him glad.
One thing he had noticed during his training was that 'normal people' couldn't see the green sparks or light that appeared whenever he used his time element.
