[You haven't been to Wanning City yet. I can't update the information there, so I can't answer you now.]
In order to limit the Guardians and not let them break the rules of the universe, usually, all the information obtained by the Guardians could only be based on the location of their ward.
If not for the fact that Meatball had threatened the spatial pocket and ran to the system world to take away some information, it would not have known that its ward had a bumpy life.
Now, it only knew some of the contents of the system world.
If it wanted to know more, Little Ah Yu had to go to those places.
However, Ah Yu was still young now, and Meatball also knew that Old Madam Wang had the intention to let Little Ah Yu wait until she was seven years old before going further.
After seven years old, it won't be as easy for others to guess Little Ah Yu's true age.
It would also protect her better.
