The Two Walls Stand Tall is Wo Long: Fallen Dynasty final two versus one stage. The others weren’t too bad, either due to weak bosses, or favorable conditions, with this having a bit of both. You need to defeat Xiahou Yuan, along with a human Xiahou Dun, at the same time. This is another fight that can be hard if you approach it the wrong way.
How to Defeat Xiahou Yuan in Wo Long: Fallen Dynasty
Set Up
Overall, good defense and fast strikes are all you need to worry about here.
Defeating Xiahou Yuan and Xiahou Dun
For this fight you want to focus on Xiuahou Dun. This is due to Dun being more aggressive, and constantly rushing you. Yuan will use any opportunity to instead shoot you with arrows. As annoying as that is, those are a lot easier to deal with than a rushing boss.
The best rotation is to try and finish Dun while avoiding Yuan. Basic evasive moves should be more than enough to do this. While doing this, keep the camera locked on both of them. Even though Dun will generally rush you, Yuan will occasionally rush as well. Deflect his attempts, while focusing on Dun, until you break one of them or they use magic to coat their weapon in flames.
Whichever target has the buff needs to be your focus. While this is active they will be a lot more aggressive, along with doing significantly more damage. Since they’re both weak in terms of spirit, a couple strong attacks should be more than enough to bring them both to stun. By being smart, keeping two steps ahead, and not being overly aggressive, you should be fine.
