Alex cultivated for some time before letting the others know of the changes. Everyone, except for Ronron, accepted his proposal to enter his Soul Space and cultivate in there.
Ronron's refusal was mostly for two valid reasons. First of all, she needed to stay out and be around her master to learn as much as she could. At the same time, Ronron had a massive Soul Space thanks to her having already absorbed a Space Stone, so her entering his world would not be a good idea unless they were certain about a few facts.
Alex decided to wait a while before he tried taking in his daughter, so she had to remain outside.
Since Alex had taken away the Demon realm after everyone had left, those who had come here with Hannah had no idea just what Alex's Soul Space was like. So, for many, this was the first time they were getting to see the location.
