With just one sword strike, Xi Xiao was severely injured.
In Xi Xiao's eyes, panic flashed as he tried to increase the distance between himself and Chen Fei, but unbeknownst to him, the space surrounding Xi Xiao had been sliced into thousands of pieces by Chen Fei.
Among them, some pieces were expanding to their limits, some maintained their original size, and others swelled irregularly.
In those thousands of space segments, hundreds were naturally collapsing every moment, while hundreds more expanded at varying rates.
This result was that the tearing forces around Xi Xiao's body were entirely different, changing every second, making it almost impossible for Xi Xiao to break free.
This was the skill of controlling the Space Secondary Rules; if Xi Xiao possessed absolute power, he could have cleared them all in a sweep, overpowering the many with strength.
