They noticed a flat field, close to a hill (now known as the Çabrati hill), and found the owners of the land, with whom they talked about buying a piece of land. The owners were Jak and his brother Vulë, and they didn’t want to sell any land. The Turkish guards managed to change their minds and they told them they only needed land as much as the skin of an ox, and the brothers agreed. In fact, they were really crafty.
