We are in 2120 and a few months ago the great discovery of the millennium was announced: the invention of the time machine.
Only a few people in the world have access to this machine, but some of them have made changes in the past and are erasing all traces of the Spanish language. For this reason, we embarked on an adventure, riding our own time machine, to rescue the Spanish language and get back four of the most important books in our linguistic history.
However, in order to start our machine, we have to make sure that you are the ideal candidate to start this adventure. For this, we have prepared a control system within the time machine, so you can only start it if you are able to find out the correct combination.
