What's the best floor in the dangerous mines specifically to farm slimes?

Need another 300 to kill and I really don't want to spend hours on this

I would search for infested floors and maybe use Monster Musk, if you already have some. Dangerous mines mode already has much more slimes than usual, so it shouldn't be hard to get 300 full... And see what the Wiki says.
Good luck!

Anything low (1-30), or higher (70-110), ideally infested, but if not, generally larger floors like a 0->15->16 and repeat is pretty good, same with 13(?), though requires more ladders as 10-12 don't really offer anything of worth.

Otherwise skull cavern, harder to kill but they're generally rather plentiful and you're not really wasting your time, as you probably have more monster slayer goals to do there than remaining in the regular mines (at least ones that actually coincide with the floors you'd be farming for slimes)
