Considering this is the final mission, it really wasn't too bad. Mainly just buff and heal when he uses impenetrable aura, and debuff as soon as it's over. As the fight goes on he grows more wings which correlate with buffs he gives himself, but Fang's dispel makes that not a problem at all. Poison is also extremely useful since it deals percentage based damage instead of a flat damage. The 5-star rank can be kind of tricky, so just play very aggressively. Overall the fight is really pretty easy, you'll likely have a lot more trouble with the Long Guis and Shaolong Guis that appear after completing the stone circle.
