"Though rare, it isn't impossible.
And this kind of wormhole passage might lead to the main universe, or it might lead to another subspace!"
Xu Zhenzhi said gravely.
"Why hide it?"
Shi Zunhou asked himself, then answered.
"Probably to keep the secret of this wormhole passage hidden, even if someone accidentally discovers this subspace!"
"True. This subspace is small and barren. At first glance, it seems to have no value at all.
Even if someone stumbled upon it, they probably wouldn't pay it any attention."
Gao Luanqin nodded.
Every subspace periodically developed spatial folds at its points of connection to the main universe.
The only difference was how long each subspace remained open.
The small fleet from the Mist Butterfly Civilization didn't leave them guessing for long.
On another Engineering Ship,
a large amount of equipment was deployed.
They were all similar in design, resembling oversized radio-frequency transmitters.
Their functions seemed similar, too.
The Engineering Ship spent some time
securing dozens of the oversized radio-frequency transmitters around the patch of anomalous space Liu Zhi had pointed out.
Then,
they activated them!
Soon,
the area that had seemed empty
revealed a "shell-shaped" sphere about a hundred meters high, as if a curtain had been drawn aside!
Immediately afterward,
a large amount of engineering machinery flew out from several Engineering Ships.
With the machinery at work,
it didn't take long
for the hundred-meter-high "shell-shaped" sphere to gather in layer upon layer.
Eventually, it formed a single structure made of an unknown material.
The things hidden inside were exposed.
Just as Liu Zhi had said,
it was a natural wormhole.
An ultra-small one.
It remained open.
The passage was only about three meters across.
That opening was far too small for ships to pass through.
But Wang Dong's eyes suddenly flashed with keen
