Depends on are you on hardmode or not, and how good weapons and armor you have. And do you have materials for Slime Crown. :P But let's say you are not on hardmode and you have decent armour. Make Slime Crowns and kill the slime anywhere you like, best place might be pretty flat ground. :D If you don't have materials or cannot acquire them quickly, water candle and battle potions are your friends.
