Pretender Realm
The Dragon Realm's capacity to accommodate True Gods is the clearest evidence; Noah single-handedly raised the World Rank.
This is certainly because of the supplement of numerous Material Worlds and the Space-Time Realm Continent, but just look at the Shattered Space-Time Realm, and you'll see that after hundreds of thousands of years, it's still just a scatter of sand under unconscious fusion.
Yet under Noah's leadership, in merely a few hundred years, the Dragon Realm integrated all worlds into one, those shattered worlds no longer exist as independent continents or half-planes.
It is precisely because of the possession of such power, combined with the addition of the Lord of the World's rank, that Noah regards many matters lightly, indifferent to the choice of offspring, even leaving them in Heaven is fine.
After all, they are his children, what's wrong with developing in Heaven? Although the gods of Heaven harbor many calculations, so what?
