Dear whoever is reading this,

There is something I must tell you! In space there is a dangerous virus creeping down to earth! I need your help please. You have to dig a path into the middle of the earth, because there you will find a ball of very hot fire which, once released, can make its way through the path and burn the virus away. This might not save you, but it will save the rest of the planet at least. I hope this message was important to you.

PS You don’t have to do this on your own.
