One-Time Event

Talking about Krune and his group, they made it further than others into the Soren Ruins' Core Region's deep parts. Why? That was mainly because of Krune's movement speed being far beyond the limits of the Mortal Realm. Any other cultivator or demon beast would have attracted way too many ghosts, making it impossible to continue forward. Not to mention that Feifei's calculations which helped in selecting the best routes.

Well, that's not considering all the cultivators that had been teleported to the weird planet. After all, they didn't go there by moving in that direction. Still, it was not as if the ghosts and the crystal demon beasts didn't notice Krune. The path behind them got more and more lively as the number of ghosts and crystal demon beast noticed their presence.
