Recommendations Looking for novels with pocket dimension / duplication / upgrade power

[MaxHax2]

Lately I've found several novels that I enjoyed a lot.
I've realized that I love the concepts and now I'm looking for others like it.

Pocket dimension: MC has it's own pocket dimension of sorts. But only he has it in his power bracket. Or he has access to it at start where others would need years of training/grinding to get or afford it.
Example: https://www.scribblehub.com/series/2076178/my-portable-spirit-farm-rise-of-the-humble-servant/

Duplication: MC has power to copy and duplicate items or skills.
Example: https://www.scribblehub.com/series/2080010/crow-immortal-i-can-duplicate-infinite-resources/
https://www.scribblehub.com/series/679342/dungeon-diver-stealing-a-monsters-power/

Upgrade: MC has power to upgrade skills or items.
Example: https://www.scribblehub.com/series/2113463/cultivation-i-can-steal-lifespan-from-spirit-beasts/
https://www.scribblehub.com/series/2122295/system-patch-i-evolved-my-frank-talent-to-sss/

It amuses me that the revival of this thread showcases the purge with half of those links being dead books now.

I've realized that I love the concepts and now I'm looking for others like it.

I do agree for some of them but it seems for the most part that the novels I do find on the concept tend to either be translation stuff, or short-lived.

Honestly I find the whole thing strange because almost always it seems to be the power-stealing that sticks around the longest, while a lot of the upgrade themed ones seem to run out of steam or chapters pretty quickly, I wonder if thats tied to any fatigue for coming up with 'better versions' of something.

Anyway I guess I'll leave post this here to keep watch on the thread in case someone comes up with something.
