Is there anyone more intelligent and studious than Visconde de Sabugosa? Well, he has now taken an interest in geology (the science that studies the origin and formation of our planet). To conduct his research, he climbs into an armadillo burrow, analyzes the soil, and discovers that there might be oil right in the middle of the *Sítio*! Thus begins an incredible journey: traveling through a volcano, our group will make its way to the center of the Earth.
