Hou Niao flew forward slowly, his mind not on the previous battle. It was merely an application of his Ascending Sword Skill; the opponent hadn't even forced out his full potential, making it somewhat insignificant.
For a Sword Cultivator, the craving for the thrill of battle is crucial. When an opponent can't ignite his desire to fight, wielding a sword becomes a simple repetition. He truly yearns for that kind of life-and-death confrontation, with opponents so strong they send shivers down his spine. Only by constantly raising the upper limit does battle hold true meaning for him.
The weak merely allow him to develop bad combat habits. Take Helian Feng, for example. He started off with some petty tricks because he's become accustomed to bullying the weak, resulting in defeat from the beginning. He fails continuously and can never recover.
