The Lizardman God Cult
Yale had decided to spy the conversation with the lizardman chief because he wanted to ensure that the lizardmen wouldn't try to betray Yale's group after having returned to the tribe.
However, the benefit he obtained from that was the recovery of some memories, so the travel to the lizardman village was already worthy.
Yale still had some doubts about the original Demon Lord, for example about the reason why Wyba wasn't called Demon Lord by the wolves despite having met the conditions even better than Yale because she was a true divine beast and possessed the same bloodlines as Yale.
However, since there was a limit to the memories he had unlocked, and it didn't seem that the chief of the lizardmen tribe would continue speaking about the topic, Yale could only forget about it for the moment.
"Quick, let's prepare a banquet for them. Ensure that they are happy and that no one offends them. Offending them is a death sentence, without exceptions."
