An alarm rang! Normal fresh morning. But professor Richardson has not slept for a long time. "Need to go to the lab"... After a few meters on the well-worn path, the professor came to the ramshackle hut. The door creaked... "Badly oiled" - flashed the thought in his head. "Well.. what we have.." - eye fell on a chest of strange forms, in a corner of the room. It lay here for a long time. "Well, need to make stuff, let's see....." To crack the lock wasn't difficult. Some pieces of old paper.... Mm... Maybe a map.. Please help the professor build a map!
