If you are a resident of one of the Schengen countries you can automatically travel in the other Schengen countries. This is not something you need to "acquire".
In theory the 90/180 rule applies, but in practice there are no border checks between Schengen countries, and your movements are not tracked, so you are basically free to travel where you want, when you want.

Having a Schengen visa only gives the right to travel , not to reside in another Schengen country. Even EU citizens have to request a residence visa for any country other than their own after 3 months , and this will only be given if the person can prove being able to support themselves through having a job or pension . And the person will also have to register their national health card with the local health authority.
