[luckily(?) 'of previous origin' is a pretty sobering reminder. ah, yes. previous to his fights in the city, which means he took this wound back in the cultivation world, which means...he didn't have to have gotten it around the time he would have killed Wei Wuxian's people, it could have happened beforehand. he finds he's abruptly mad about it again anyway, on some level.

wait, though. what leaves a permanent mark like that on a powerful cultivator's flesh? or is it a permanently healed mark? is it actually a curse?

anyway now he's going to try to grab the panel of robe aside for a better look.]
