There is a branch line in the later stage of "Fairy Sword Sanli".
In the later stage of the game, you can fly back to Yuzhou with your sword, and you can trigger a side plot at Xiaoyao Inn: with Li Lan, the new owner of Xiaoyao Inn. During the conversation, we learned that he was a descendant of the Bashu thief Li Hankong (the owner of Jingjing, the legendary Sedum Flying Dragon that detects clouds), and named his two sons, one of whom was later Li Sansi.
