It has been a few days since Benimaru and other ogres joined Rimuru. Gabiru arrives at Rimuru's village to try and get everyone to serve under him to fight the orcs. Gobta is sent in to duel against Gabiru, defeating him quickly with the skills he's learned and forcing the lizardmen to retreat. Later, Rimuru is approached by a dryad named Treyni, who asks him to defeat the Orc Lord. (Source: Wikipedia)
