The nature of a space wormhole was similar to that of a portal.
Both required power to keep their passages stable.
Portals were powered by energy crystals, magic crystals, and the caster's magic power.
Wormholes, meanwhile, were powered by feeding rare minerals to a Jumping Beast, which digested them to supply energy.
Its body would merge with the wormhole, becoming the passage's framework and energy source.
Power was supplied from this end-the Kona Satellite side-to keep the entire passage running.
The other end was merely an exit.
The exit had no energy source and no target that could be attacked.
This was also why the wormhole on the Terra Continent could not be destroyed by nuclear bombs and could only be dismantled through spatial magic.
A technological civilization had only one way to destroy a wormhole.
It had to fight its way through the wormhole to the other end.
Then it had to find and kill the Jumping Beast that had already merged with the wormhole.
Otherwise, with the Demon Clan supplying it, the passage would remain open indefinitely.
The only window of vulnerability was during the wormhole's opening.
When the passage first tore through space, both ends were extremely unstable and could collapse under an external impact.
Once it stabilized and took shape, the exit would be impregnable.
That was why Cho'Gath had demanded that the other end open underground.
Deep underground, it would be far from the surface and the technological civilization's surveillance from the skies.
Once the wormhole stabilized, even if it was discovered, the enemy would be unable to do anything about the exit.
The Demon Clan Army would already be pouring endlessly out of the wormhole, striking from beneath the enemy's feet.
The Jumping Beast's skin rapidly cracked and collapsed, blue-black spatial energy surging from
