Seeing how happy Qing Yi was to show Mui around, Xuan Hao waited for Qing Yi to introduce herself to Mui and for Mui to grow comfortable around this new senior sister before leaving the two of them alone. Deciding that it would be a good idea to meet up with Elder Song and Feng Chen while Qing Yi was busy showing Mui around.
As for introducing her to his other two disciples… That was something that could wait for later, or maybe Qing Yi would be able to do this for him if she met up with those two while showing Mui around the sect. After all, it would be good if his disciples could take care of something like that by themselves instead of needing him to be around to do the introductions.
