Resolved Cultivators have an inner storage space

I'm looking for a novel that I read ages ago but can't remember. I'm pretty sure that people didn't need storage rings because they had an inner space where they could store their items and it would be destroyed when they die.
Also (not sure if they are the same novel or different) i remember there was a part where the mc came into contact with a pack of rats or some creatures like that and they started to go around with him (also pretty sure he stored them in a special space so he could carry them with him)

 

Dragon-Marked War God
I think

 

I think it is Sovereign of the Three Realms

 

'Shadow hack '
Nad rats situation i have seen it in the a novel 'rebirth of the genius creator and destroyer '

 

Rise of Humanity,aside from the rat situation

 

I think its called "Coiling Dragon"

Its also has a chapter named: Book 10, Baruch – Chapter 43: The Ratmageddon Wave
