Operación rescate

At Ulises y Lía's school, students can choose between several extracurricular activities. Against their will, both end up in Total Adventure class with Professor Hache, a strange and sullen old man. What Ulises and Lía don't know is that the professor is hiding a secret and that they are about to embark on a hectic adventure. Since Roxlo was captured, Ulises and Lía only wish to return to Eternia to rescue him. The problem is that Professor Hache has been tinkering with the ship for weeks and it seems that the repair is going to be long. Until one day Lía can't wait any longer and gets on the ship dragging Ulises with her. In the blink of an eye, they are racing to Eternia in search of Roxlo. But what they do not imagine is that, after a somewhat improvised landing, a long and arduous journey by land, sea and air awaits them. And is that Eternia is full of surprises and they still have a few to discover.
