* '''Acid''' - If you don't have a strong enough pick axe, use acid. [[Sulphuric acid]] is very useful for this. Just throw the bottle at the wall and within a few seconds it will dissolve. Make sure to have strong acid protection though, or it will melt your feet off too! Supposedly vomiting Another option is to vomit on the wall works too. This will not dissolve the wall, but vomit is very weak compared if you give it some time, it will cause the wall to sulphuric acid. Mines and even big mines are not even strong enough rust, which makes it easier to destroy the wallsdig through.
