That little bit of fear is what Wei Wuxian needs to see. To know that he is still in control of the situation even if he hasn't yet gotten the information he desires. He ca piece a few snippets of information together and is smart enough to figure out some things on his own but he just needs a bit more. There is much that he doesn't know about those sixteen years he was gone from the cultivation world. But the important pieces of information are there. He just has to be careful how he words things because in many instances the people who died...did not do so directly by this man's hand. But rather an extension of it.

So instead he decides to switch gears slightly, letting himself keep his eyes on Jin Guangyao's expression for any small change in it by what he has to say. "What I know is that Nie Mingjue is dead. Jin Guangshan is also dead." If these two names draw no surprise then this Jin is quite young. So he moves on, "Jin Rusong is dead." A little further up the timeline and a bit of a jab if the man recognizes the name. If he doesn't...well it goes far to know when this man is from.
