Hundred Thief Task Force tracked down Shadow Killer's location, allowing Nie Yan to proceed with assassinating Shadow Killer. As for the method, it would depend on the situation.
If he could successfully finish off Shadow Killer, he could then assassinate three people; Nie Yan already had a plan in mind.
"Did Shadow Killer come looking for you?" Guo Huai asked. Nie Yan wouldn't have him search for Shadow Killer without reason; they must have encountered each other again.
"I was almost ambushed by him." Nie Yan said, it really was a close call earlier. It was lucky he used his Death Immunity Skill in time. Otherwise, if he had been just a step slower, he would have been done for.
