The name Lu Chen is still somewhat sensitive in the Tianyan Immortal Domain. After all, many top-level forces had sent people to besiege Lu Chen back in the days, especially the Heavenly Splendor Hall, which even dispatched an Immortal Venerate to take action against Lu Chen to eliminate him.
If the news of Lu Chen being in the Mysterious Moon Palace gets out, those top-level forces might still send people to the Mysterious Moon Palace to trouble Lu Chen.
Moreover, Lu Chen is one of the only two people known to have survived the Chaotic Sea in the history of the Tianyan Immortal Domain, the other being the Demon Emperor. Thus, these top-level forces are definitely eager to know what exactly is in the Chaotic Sea from Lu Chen.
This left some of the Elders present a bit perplexed. Many of them had followed Yun Yudie out of the Mysterious Moon Palace, so they knew well what kind of grudge Yun Yudie held against Lu Chen.
