Flying Demon and Dreaming Demon focused on training and stretching the boundaries of the separate dimension as soon as Chasing Demon completed the array that Thirty-seven had designed.
The yellow sand of the desert lost part of its shine after that project was completed, but no trace of the formation could be seen from its surface.
The formation was meant to hide the separate dimension from Heaven and Earth, so it featured subtle lines that couldn't be noticed from above the sand.
Of course, that was only a precaution.
The Hive wasn't trying to copy the Mortal Lands.
It just wanted to make a tunnel to ambush enemy forces.
That structure wouldn't cause the anger of Heaven and Earth, at least in theory.
However, Thirty-seven still suggested adding that layer of protection in case the world noticed some similarities with the dimension created by Divine Architect.
