At this moment, Xu Xiaoshou suddenly realized that there was a difference in the big and small worlds.
It was true that people could live in the Yuan Mansion world in the past, but that world didn't have a suitable climate or any Yin and Yang. It was a world that had terrible conditions.
It had the potential to become the best world, but it required too much effort. Without the help of the Ancestor Tree, whether it would be able to evolve successfully in millions of years was unknown.
Even better than the Yuan Mansion world, was the extradimensional space like the White Cave.
Although those places were not suitable for human habitation, they had the embryonic form of a small world and their lives were able to evolve together with the World Order.
It wasn't suitable for Spiritual Cultivators, but it was definitely suitable for creatures of the original world like Ice and Ember.
