Aeternus made the demon gods arrive before the Tyrants could see the image of the abyss through the barrier and prepare for it. This ensured that the Tyrants were caught off guard, and the possibility of total realm destruction became a certainty.
But Aeternus couldn't take full credit for this achievement. He muttered inwardly as he saw the events happening in the Tyrant realm through Helios' eyes, "I am sure this is the main reason the realm lord offered the demon gods a deal. He might have made it look like he didn't want the demons to betray the realm, but I am willing to bet it was to achieve a swift victory in the era of conquest."
From the investigation that the tree father had done, he knows that the Tyrant race is a powerful race. Every inhabitant of the realm is at least at the titan of law level, while the top powers are at the Origin god level. The High Heaven realm had to remove the suppression of the realm and offer many benefits to get that kind of power.
