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

"Master, what is the Heavenly Grotto?"

Unable to suppress his curiosity any longer, Xu Yan finally asked.

"The Heavenly Grotto,"

Li Xuan's eyes deepened, and he slowly said, "When your strength becomes powerful, your horizons broaden, and your understanding of the Domain deepens, you will naturally come to know.

"If your master told you the root of it directly, you would lose the heart to seek, and that might not be good. It's the desire to explore the mysterious that embodies the spirit of seeking in the Martial Arts..."

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

As a peerless senior figure that transcended the Domain, the all-knowing master could not admit his ignorance.

Therefore, Li Xuan looked at his disciple with a teaching tone and said.

"Master is right!"

Xu Yan was momentarily stunned, then nodded his head, finding his master's words to be sensible. Losing curiosity about the mysterious would diminish the heart of seeking.
