any method is proven to be futile

It's impossible to take apart, I know ;-;

I’ve tried everything
wedge on a couch and use the brick remover, tried using another Lego to create a lever effect, using bare hands (bleeding occurs), stepping on it (wtf was I thinking), dunk it on hot water, using a wrench and pliers, tried smacking with a hammer (only chipping happened)
It’s currently stuck there for 3 years and the rod is still not moving a millimeter at all. Can you perhaps suggest more methods?

I've tried all hat too
Nothing works
It's like literally impossible

That*

Is it worth it to destroy the piece and salvage the rod?

Probably yea

I might do it just because the rod has more value than the multi sided brick
