What Happens Next in Third Nephi?

In third nephi, the saviour chooses to focus on scripture. And he commands them to search the prophets. This is in chapter 23, verse six. He takes time to patiently remind them of a significant event am that they haven't included. So i suggest to readers, and in this case, listeners, is what happens next? What if it did include the story of samuel lamanilicite? How were we to lose samao the entire part of the book of mormon? That's what i really felt wake was it not so?
