The Dark Net, Cursed Zone.
This was a zone that was full of danger, electromagnetic storms, space rifts, all sorts of dangerous environmental hazards were spread out throughout the whole Cursed Zone.
For these reasons, the Cursed Zone was not a suitable place for intelligent lives to live. This place became an optimal place to hide secrets, the technology that had been developed here was close to the power of the Big Five. If anyone wanted to hide something, there was nowhere else that would be safer than the Cursed Zone.
Regardless of how hard the Big Five tried, they wouldn’t be able to invade into the Cursed zone because they didn’t have Sky Howling Wolf’s star map. Regardless of whether it was the regular side or the reverse side of the universe, it would be lethal for anyone who did not have the appropriate star map. It would be like swimming naked in an ocean full of sharks. You could never predict when you would get bitten.
