Angshan's swordsmanship seemed to lack any flair, but it was incredibly effective. Almost every attack targeted either Han Yu's neck or his heart, and if it connected, it would result in severe injury or even death.
This was a swordsmanship Angshan had realized from fighting with wild beasts since he was young; not a single move was fancy or superfluous. Rather than call it swordsmanship, it was more like a technique for killing.
Moreover, Angshan had great stamina. Despite having swung his knife so many times in such a short period, he didn't appear tired at all, and his movements still maintained their form, persistently attacking Han Yu around the room for several minutes.
However, Han Yu's performance wasn't lacking either. Apart from the first attack that nearly opened his chest, not once did Angshan hit him afterward.
