Han Sen had made up his mind to practice Bladestorm in the contest by using Bladestorm only when facing his opponents. If others dared to do this, they might have died a million deaths already. But Han Sen was in sacred-blood armor, so hardly any attack was fatal to him. That was why he could practice in the contest.
Han Sen had given up on using his mutant sawfish spear. Without good spear skills, this weapon was useless in front of these champions.
Fighting opponents of different styles, Han Sen had made great progress and his Bladestorm got better and better--as long as his opponent was not too fearsome, he could always cope with using just Bladestorm, but it was always the bloody slayer that got him the victory.
This way, Han Sen's matches had become very hard to watch. He was always winning by a narrow margin and there were times it seemed that he was about to lose.
