Elaina spends her time destroying the crates one by one with her pickaxe. They are easy to break so it wasn't a very troublesome thing. One thing she discovered is that all of the crates have a chance to spit out random items and there are also chances they don't have anything at all.
Still, she managed to get various items so far. She even got a few stuff like logs from freshly cut trees and a few round stones that she saw being used by Jacob for repairing the farmhouse and creating the chicken coop one time. But they are rare occurrences and most of what she has gotten from those crates are the canned foods.
When she destroyed the final crate, the path to reach the 5th floor appeared before her. But compared to the previous floors, this one is giving off a familiar but stinky smell.
"Rotten eggs? No... it's something similar. Not exactly rotten eggs."
