You two did not arouse anyone's suspicion and soon arrived at the "Magic Communication Zone," the World Passage maintenance area.
It seemed the Dragon Person Race loved using the word "magic" to name some of their things.
Alien Race culture—neither understood nor respected.
You saw many spatial vortexes here.
A stone stele stood before each vortex, its surface inscribed with the name of a world in the Dragon Person Race's language.
Wing World, Sea Fork World, Three-Eyed World, Madman World, Minotaur World...
There were eleven World Passages here.
People came and went from time to time.
Clearly, they were all functional and could be used to travel between worlds.
"Eleven World Passages—does that mean Dragon Person World has only conquered eleven worlds so far?"
"Far more than that. Maintaining a World Passage consumes enormous resources. Only worlds that still have strategic value and need mutual exchanges will keep their passages."
"There's no passage to the Human World here. Ask around and see whether one can be opened."
The two of you pretended to make idle conversation. Ka Er, being quite streetwise, handed two sticks of Dragon Person Incense to the guards watching over the World Passages.
Like cigarettes on Earth.
From the guards, you learned—
Three-Headed World possessed a complete Qiankun Space Cannon, had already preserved the Human World's coordinates, and had sufficient Magic Crystal Stones to open a targeted rift.
But because the Human World lacked the "Magic Void Array" needed to maintain the rift, even if it could be opened from this side, it would only last for an instant and could not be considered a passage at all.
You asked again: if someone seized that instant and rushed through, how many people could enter?
You learned that at the Spirit Condensation Realm, only one person could enter.
