To be honest, the power of the dragon veins in the Tomb of Ten Thousand Dragons was beyond his imagination. Now, he could only try these methods to see if he could completely purify the Skin-Peeling Ghost King.

The corpse of the Skinning Demon King quickly turned to ashes, but Zu'an frowned because a phantom suddenly floated into the sky.

"I never expected you to be so powerful. Normally, even ten of you wouldn't be a match for you. It's just a pity that we dead are immortal. Being killed by you this time is merely returning to the nearest hell. Now I'm even closer to the gates of the Netherworld, destined to go here. Speaking of which, I should thank you for sending me on my way." The phantom of the Skinning Demon King laughed heartily.

Zu An's expression was solemn. He used the Gluttonous Devouring Heaven Technique to try to pull the phantom over, but the other party was enveloped by a mysterious power. That power seemed to be the most primordial law in the world, irresistible and incomparable.

Under the pull of that supreme law, the phantom of the Skin-Peeling Demon King swiftly plummeted into the abyss below and vanished.

Zuan: "..."

At this moment, Shang Liuyu comforted her, "You've done very well. I was scared out of my wits just now. At least you're still unharmed, which is better than anything else."

Zuan sighed: "If the Skin-Peeling Demon King really passes that trial and obtains the beacon of the world's laws, that's when the real trouble begins."

However, his emotions did not fluctuate much. At worst, he would guard the World Law Beacon and kill the other party every time they came back to retrieve it after passing the trial.

Now, with the help of countless dragon energies and dragon veins within the Tomb of Ten Thousand Dragons, he has unprecedented confidence.

Just then, an ancient and desolate voice suddenly resounded between heaven and earth: "Fated one, do you wish to participate in that trial?"

Zuan and Shang Liuyu were taken aback upon hearing this, and subconsciously looked around, but did not see a single person.

Zu An frowned. Although he was no longer using the power of the dragon vein, even with his own cultivation, within the range of his divine sense, not even a mosquito could escape his perception. But this voice seemed to have suddenly appeared, and he couldn't pinpoint the other party's location at all.

This is quite a bizarre thing, and it really defies common sense.

Zuan activated the "Dripping Heaven Essence: A Subtle Explanation" again, drawing upon the power of the dragon vein. Suddenly, he opened his eyes and casually waved his hand, unleashing an invisible burst of energy that separated the dense, grayish-white death energy between heaven and earth, revealing a massive statue.

Shang Liuyu looked up and was immediately horrified.
