Empirical Sword

Qin Xuan let loose a flurry of attacks towards Han Sen, who remained in a defensive position, allowing her to do as she could. He was able to block each and every strike.

The dongxuan aura allowed him to sense all things, but Han Sen had previously stuck to only using it to observe lifeforces. As he shifted his focus on the skill, it began to feel more and more like the eighth sense.

Han Sen used his feelings to block Qin Xuan's attacks, and did not actually watch her with open eyes. The more he practiced, the greater his abilities of perception became. It wasn't quite on par with the eighth sense yet, but he wanted to get it there.
