Not even the temptation of the Tree Father could make GREED stay. It prioritized its life above its GREED immediately it saw Aeternus.
GREED had heard a lot about Aeternus, so it didn't bother to fight when it confirmed what it heard through its sight. As they say, seeing is believing. It believed that it would die, so it ran.
Aeternus ate demon gods, while the Tree Father refined abyssal planes. Unlike the high heaven realm, the abyss of the Tyrant realm has fewer abyssal planes. Even so, there were more than 666 abyssal planes, as that is the minimum for the abyss. That means it will take a long time for him to refine them.
The first abyssal plane had cost him six months of time to inspect and analyze before the refinement. At that rate, the remaining 700 of them will cost him 350 years to refine. It is a long time, but he can't complain. After all, he is growing stronger by doing it.
