One Hundred Swords couldn't correctly cast Ten Thousand Swords on Han Sen, and without further ado, he conceded and abandoned the battleground.
Although Han Sen won, it wasn't a scary and unsettling victory like Elysian Moon's wins. When Han Sen reached the next round, all his opponents decided to fight until there was no choice for them but to concede.
Han Sen's sword skills were very suppressive. He couldn't kill his opponents in one hit, so there was no need for any of them to truly be afraid.
This did give Han Sen the chance to practice more and more with the technique, though. All his opponents were super creature or king spirits, and fighting against them challenged his proficiency with the sword skill.
It did not matter what the abilities of his opponents were, as Han Sen could change his moveset on the fly to respond appropriately. While his strikes changed a lot, the base of the skill was still focused on his formation and judgment.
