Zhangsun Shan and Qiu Si of the Taiyi sect. Even though both used the same moves in the beginning, which evolved into two different monsters of a move, the style that they had was completely different as well. While Zhangsun Shan was relentless with his attacks, Qiu Si was much more manipulative, which made sense, since she was the one who actually led the battle against the Blood Moon sect sending her husband out front to wreck everything up. She was a natural born military strategist who takes her time to conquer the battlefield. However once she does triumph, no one dares to even challenge her.
Although this was the case, no one believed in her too much in her early days because of this slow style. The Taiyi sect were a group of hot headed people. So, for them to see such a methodical approach was… boring to say the least. But, if one was to think about it, this hotheadedness was the same reason that they completely lost their identity in a day.
