Master Moran wasn't interested in Master Yuan. First, he wanted to take care of his own people, and second... he suspected Master Guyue's information might not be accurate. Bringing another person in could mean fewer treasures, which would be a loss.
Adding Master Wu Xiu into the mix made him quite uncomfortable. He somewhat regretted listening to Guyue's suggestion.
Upon hearing that Master Tuantuan prepared "too many" treasure details, his frustration vanished.
Mind you, this is someone who has been surviving in the Hot Spring Plate for 150 years, without giving up on preparing for forming his Nascent Soul. Could the treasure details he prepared be few?
As for some close siblings not being able to catch this ride, it doesn't matter anymore. He must first ensure his Nascent Soul formation before he can help others. If he perishes, nothing else matters.
