Facing Qin Yu's questioning, Su Tan and Lin Yin immediately informed him about their children's survival.

After Qin Yu heard this, without even thinking, he said to them, "This emperor will do it for you!"

After he finished speaking, he took a step forward, and the horned dragon behind him moved like a shadow. It instantly appeared below his feet, and carried him into the sky.

Seeing that, Su Tan and Lin Yin were startled, they thought to themselves, they have not even mentioned the exact location of their children, why did Qin Yu leave already?

Just as they were lost in their own thoughts, they heard an urgent voice.

"Elder Su, Sect Leader Lin, let's go …"

These words came from Hua Yuye and the rest. Su Tan and Lin Yin reacted in an instant, they immediately rushed out and caught up to Qin Yu, and the rest of the people followed closely behind.

"Sect Leader Qin, Little Wen and the others are here …"

After Su Tan caught up to Qin Yu, he wanted to tell them where he was going, but before he could finish, Qin Yu had interrupted him.

"Enough. There's no need to say anymore. This Emperor already knows. Just follow me!"

When Su Tan and Lin Yin heard this, they were stunned for a moment, completely unable to react.

They were only informing Su Xiaonuan and the others that they were trapped in an underground palace called the Immortal Dragon Elder. They did not point out their location, so how did he know?

They, who had reacted, looked at Qin Yu's back and felt astonished.

Little did he know that in the process of Qin Yu destroying the primordial spirit of the grey-robed leader, he had long understood all of the other party's memories.

He now had a new understanding of everything in the Heavenly Imperial Palace.

Who exactly was this grey-robed leader?

Actually, to say that he was the leader of the group of gray robed people, it would be more accurate to say that he was the clone of the Heavenly Imperial Palace's artifact spirit.

This was because he was one of the Heavenly Imperial Palace's artifact spirit s, who was using the Divine Clone Technique to possess one of its corporeal bodies.

Of course, only Qin Yu knew this secret, so everyone was very surprised.

The memories of the Heavenly Imperial Palace's artifact spirit carried all of the past millions of years of history of the Heavenly Imperial Palace.

And this Immortal Dragon Elder was the previous master of the Heavenly Imperial Palace.

The Dragon Blood Emperor Seal was created by him, but later on he used a heaven-defying technique to forcefully reform the Heavenly Imperial Palace, allowing it to form a core.

Without this core, the Heavenly Imperial Palace was not perfect, and the artifact spirit could not get out. This was why the colorfully robed man with the jade crown was thinking of ways to snatch the Dragon Blood Emperor Seal.

Because without the Dragon Blood Emperor Seal, no matter how powerful he was, he could not escape from the Heavenly Imperial Palace. Because from the very beginning, he was trapped in the center of the world and his spirit was unable to escape from it.

The Immortal Dragon Lord's underground palace was a thousand miles away from the center of Heavenly Imperial Palace. All the experts stepped into the air and arrived above the Yin River in the blink of an eye.

Looking at the gnaw marks on the skeleton below them, everyone's faces couldn't help but twitch.

They all looked towards the source of the Yin River. They were shocked and faintly felt a sense of unease, as if something was lurking there and was threatening them.

Qin Yu maneuvered the horned dragon and when he passed by the place, he suddenly stopped. He looked at the source of the Yin River and a sly smile suddenly appeared on his face.

"Up to the ninth heaven, passing down the nine nether regions and the netherworld as the world, becoming one with heaven and earth. Interesting …" Qin Yu suddenly muttered to himself, and waved his sleeves, sending the Hell's Wand flying towards the source of the Yin River.

In that instant.

Hungry ghost fish filled the skies, causing the world to change color.

All the experts retreated, but Qin Yu remained unmoved.

He raised his hand.

The two giant Devil Bee of Hell spread their wings and flew straight towards the sky full of hungry ghost fish.

Devil Bee of Hell was originally a demon from hell, so they loved the miasma the most. How could a mere hungry ghost fish shake its might?

After releasing the Devil Bee of Hell, Qin Yu no longer bothered with them. He urged the horned dragon to continue moving forward, and only stopped after they had reached the depths of an endless mountain range.
