Han Sen believed going up against Six Paths' Life Sword would be difficult. After all, Life Sword resided at the heart of Six Paths. It was his essence. If you took away the limitations of skills, all he had left was primitive drive.
Six Paths' sword skills, when cast, were something scary to behold.
This would be the sixth sword skill, and it was the only one from the set Han Sen had heard about, but not actually seen in action.
It wasn't that Six Paths did not want to show it to Han Sen, it was just that Life Sword was something of a personal achievement to learn. It was pointless to simply see it.
But Han Sen knew it was strong. He just didn't know how strong. And now that he could see it, he was getting a feel for its power. It wasn't as threatening as Blood Sword, though.
A battle that was based on reactions and strength was something Han Sen was good at. That was what he did before he amassed an array of hyper geno arts, after all.
