However the orc explains he is just an Orc General and the Orc Lord is much more powerful, but he accepts his fight challenge.

An orc then attacks them and the ruler decides to fight him, while gives his daughter a special order and lets her escape.

Rimuru's is getting closer to the lizardmen tribes and decides to take a break. Rimuru had brought the kijin, Ranga and a hundred pairs of goblin raiders, but doesn't intend they to fight and instead wants them to make an opening so that he can fight the Orc Lord. Souei scouts around and sees the lizardmen's ruler daughter fighting a higher orc and 50 other orcs. Rimuru tells him to save her as he wants to talk with her. The higher orc defeats the lizardman easily and prepares to kill her, but Souei jumps in and easily defeats the orc. Rimuru comes and gives healing medicine to the lizardman. Souei had left the orc alive as Rimuru may need to question him. The orc still intends to fight, but Shion shows up and kills him taking the questioning chance away from Rimuru. The lizardmen tries to warn them that there are 50 more orcs nearby, but Benimaru and Hakurou had already taken care of them. Recalling what her father order to find Souei and explain the situation, the lizardman asks Rimuru to save her brother and father as her brother had taken the ruling power. As he looked down on the Orc Lord, he will be defeated and the lizardmen will be destroyed. Shion is impressed that the lizardman had felt the Rimuru's power and states the lizardmen will be saved, even before Rimuru had agreed to do so. Having no choice, Rimuru agrees and wants Souei to use Shadow Step to reach the ruler.
