"The Outer Realm Passage?" Qin Hao noticed that the Young Heavenly Dao had mentioned this term several times now. Although he had not asked about it in detail before, he had a rough idea of what the Outer Realm Passage was.
A passage through which the Outer Realm Demon Spirits sought to invade the Star Sea.
Or rather...
It was a passage connecting the Star Sea to the outside world.
Of course, this outside world did not mean realms like the Primordial Sea or Heavensea, but a world beyond this one.
"Correct. If the Outer Realm Demon Spirits want to invade the Star Sea, they can only do so by opening a passage like this," the Young Heavenly Dao said gravely. "Because of the spatial barriers, even other worlds cannot easily break through. Opening a single passage already takes everything they have."
Spatial barriers!
Spatial barriers existed not only between the Star Sea Heaven and Earth, the Primordial Sea Heaven and Earth, Heavensea Heaven and Earth, and the many other realms, but also between this world and worlds beyond it.
Moreover, these spatial barriers were often sturdier and far more indestructible than those between the Primordial Sea, Heavensea, and the other realms.
If a True God might have a slim chance of breaking through the spatial barriers between the various realms within this world and successfully reaching another realm...
Then even an Eternal True God could not travel here from another world.
That was the difference between the two kinds of spatial barriers!
In other words, one spatial barrier was greater in scale, while the other was relatively smaller.
Hearing the Young Heavenly Dao's words, Qin Hao's heart sank slightly.
The Outer Realm Demon Spirits still sought to invade the Star Sea Heaven and Earth.
This was not good news...
