Chapter 655: Chapter 349 This is a real master, truly too high

"Master, what is the Heavenly Grotto?"

Xu Yan couldn't suppress his curiosity anymore and asked.

"The Heavenly Grotto."

Li Xuan looked profound and slowly said, "Once your strength is formidable, your vision expands, and your understanding of the Domain deepens, you will naturally come to know.

"If your master directly tells you the origin, losing the heart to seek might not be good, possessing the desire to explore the mysteries is indeed the essence of seeking in Martial Arts..."

What the Heavenly Grotto was, Li Xuan naturally did not know.

As a transcendent master detached from the Domain and omniscient, he naturally could not admit his ignorance.

Thus, Li Xuan, with a teaching tone, said to his disciple.

"Master is right!"

Xu Yan paused for a moment and then nodded, feeling that his master's words were reasonable. Losing curiosity about the mysteries, the heart for seeking would indeed wane.
