Some answers

The figure spent quite a long while detailing exactly how Lex could use the soul sense, and the list was honestly longer than Lex expected. He never really thought about it, but suddenly it made sense that cultivators had such long life spans, because he could not even estimate the number of years it would take him to learn how to fully utilize his soul sense. In fact, a part of him was fairly certain that even the spirit sense was severely underutilized, but at least with that, information was common enough where Lex could investigate on his own.

But based on the fact that the figure had not vanished after answering the question meant that he could still ask more questions. A part of him was really tempted to just ask him the cause of the anomaly in the Crystal realm. Since he was supposed to ask questions that would give him immediate benefits, that was one of the big ones. That was what the logical part of his brain told him.
