753. The Overlord's Fawning, Wisdom King Secret Realm

True Monarch Purple Cloud and Venerable Leiyin listened until they were dumbstruck, stormy waves surging in their hearts.

Good heavens!

Dragon Eagle Cave had hidden itself far too deeply!

They had known each other for ten thousand years, yet they had never heard even the slightest hint of this!

No wonder Dragon Eagle Great Emperor was usually so low-key, yet no one had ever dared provoke him. So this was the background behind him!

"Amitabha, excellent, excellent!"

When Shiluo heard this, a rare look of joy appeared on his face.

Facing the empty space before him, he pressed his palms together and said softly, "Senior Brother, we have Demon Emperor materials."

"Senior Brother?!"

The three overlords froze at the same time, their faces once again filled with shock and confusion.

Dragon Subduing Arhat's senior brother?

Wait!

Aside from Shiluo, there was another Heavenly Sovereign powerhouse in this Great Luo Heaven Domain?!

They had previously sensed the entire Great Luo Heaven Domain, and they had clearly detected only Shiluo's Heavenly Sovereign aura!

Just who exactly was this hidden Heavenly Sovereign?

To think he could make Dragon Subduing Arhat respectfully address him as Senior Brother?

"Buzz."

Just as the three of them were in shocked uncertainty, the space before Shiluo rippled slightly.

A figure slowly stepped out of the void. He wore a simple gray robe, his features handsome, the corner of his mouth carrying a faint smile. There was not the slightest fluctuation of Spiritual Energy around him, making him look just like an ordinary mortal.

Yet the instant he appeared, the air in the entire Great Luo Heaven Hall seemed to solidify.

"Boom!"

The three overlords felt a vast, boundless, terrifying pressure, as if it could burn all things to ash, silently envelop them.

This pressure was even more domineering
