Back then, Nie Yun hadn't had the chance to study Assassination Qi before that Assassin Master took his own life. As a result, he never formed the so-called Assassination Dantian and couldn't possibly use the Assassination Technique.
His previous move was merely an imitation of an ordinary assassination technique. It lacked the one-hit-kill capability of a true Assassin Master. Even if the middle-aged man hadn't charged over, Nie Yun wouldn't have been able to kill Lik Nansou. The entire purpose of the act was to lure him in, release the Heart-Devouring Poison, and kill him with it in a single stroke!
The middle-aged man was the controller of the Array. As long as he was poisoned to death, the Array would naturally become meaningless.
"What?"
"Is that a poisonous gas? How can there be a poison this potent...?"
