The battle between the old and new rulers had always felt inevitable. The siege at the orange city didn't even surprise Noah after everything that had happened during the apocalyptic event. Heaven and Earth could find and hunt down magical beasts, so it naturally had the power to use the new environment to find other hated enemies.
The new control that Heaven and Earth could have over the higher plane was the very reason behind Noah's decision to make his quasi-living workshops small and faint. He couldn't reduce the destructiveness of his influence, but the rulers would have a hard time finding his creations after they went dormant.
Moreover, Noah had always planned to plant many of them to make their complete annihilation impossible. The weak sky gave him a constant stream of energy that he could steal, so mass-producing his quasi-living workshops wasn't a problem.
