Heiji Secret Realm.
Venerable Huozhen took Dongguan through repeated teleportations within Heiji Secret Realm. Along the way, they encountered danger several times, but fortunately avoided each one.
"There are way too many black holes in this black sea!"
In the darkness, Dongguan complained to Venerable Huozhen.
Just now, they had teleported near a black hole.
However, none of those black holes had been particularly large. Venerable Huozhen, a Universe Venerable, and Dongguan, whose divine body was no weaker than a Universe Venerable's, had both withstood them and escaped.
The only problem was that they had ended up looking rather bedraggled.
"Master, there's nothing we can do. That's just how Heiji Secret Realm is." Venerable Huozhen spread his hands helplessly.
Fortunately, he had now broken through to become a Venerable. Had he still been an Immortal, he would never have dared teleport within Heiji Secret Realm.
Countless black holes formed and perished within Heiji Secret Realm's black sea.
Moreover, the realm's environment interfered with perception. They could only be detected once one drew close enough.
Generally speaking, although Immortals could survive and explore within Heiji Secret Realm for long periods, if they teleported and were swallowed by a black hole, they would most likely be unable to withstand it.

This was also the fastest way for beings of their level to leave Heiji Secret Realm.
Of course, ordinary Universe Overlords, Immortals, and even those
