C716 Depart to Immortal Domain
This is not to say that no one else in the Immortal World is qualified enough to do this. Actually, it's just to see if the devil race will really invade the Immortal Domain and send a cultivator over. I have other important things to do in the Immortal Domain.
It's partly because the entrance to the Immortal World is in the Immortal World and Wu Ling'er's soul is still in the Immortal World
