There's the likeliest option, which is during the Sunshot Campaign, Wei Wuxian fought closely alongside Nie cultivators or even Nie Mingjue himself. And they would have had to have been close together cause it would be hard to memorize a blade form in the midst of battle while also playing a flute that controls the dead.

Then there's the second option, which is during the downtimes of the war before battles, Wei Wuxian would watch the Nie train. The reason why? Well:

Wei Wuxian has been shown to have an interest in sabers, even though we've never actually read/seen him use one. During the burial mound days with the Wens, his study/room was said to have more than one saber inside. What was he using them for? It couldn't have been for defense cause he would have given them to the few Wens that could possibly fight, and he possibly could've/would've taken one to Jin Ling's one-month celebration if he could wield one. Was he studying them? What for? Why? What type of metal were they made out of? Iron, like the Stygian Tiger Seal? Where did he get them? Who crafted them? Why would he get sabers when both he and the Wens use sword forms?
