The good mujin may still be trapped in the past in the tree where he destroyed the monster, so the mujin at the end is the bad who for some reason is in the present or maybe probably like you said there may be a portal, and it may be that Hwon can make the portals and making him remember the past or something, so maybe the copies of the other bad kings will also appear. there's a lot to think about
