Jun Wuyi was giving full vent to the ten years of accumulated grief and resentment at this moment! He attacked with punches after punches. And, the cruel sound of his opponent's body being hit seemed like the most beautiful music to Jun Wuyi's ears.
Xiao Han didn't wish to 'insta-kill' Jun Wuyi with his sword. He wanted to torture the Supreme Commander in a slow and dragged-out manner. Similarly, Jun Wuyi didn't wish to leave Xiao Han alone either. Moreover, he didn't even desire to crush the man's skull with his fists very quickly. And, that's because that would be too easy a death for him.
