Before the Investiture of the Gods calamity, Xuandu the Great Magus, disciple of the Taiqing Sage, took the alias Xuan Xin and descended into the mortal world to cultivate because his cultivation had reached a bottleneck. There, he met Ao Run, the future Dragon King of the West Sea.
Ao Run: Xuan Xin, I like you so much! Let's become Dao companions!
Xuan Xin, Xuan Xin, hurry up and say yes, or I'll cry...
Xuandu: You wicked demoness! How dare you disturb my Daoist heart!
Who knows how many years later...
Xuandu: This is actually pretty good.
