They can be wiped out in an instant.

Without even blinking!

But how could he possibly allow the Heavenly Demon to destroy the human world?

He looked at Moro and said, "You can see that I am human, I belong to the righteous path, and I would never learn from your demonic ways. I cultivate the Great Heavenly Demon Path only to suppress the Heavenly Demons and comprehend the Heavenly Dao. From now on, you'd better restrain yourself a bit. Even though you are a demonic spirit, you must walk the righteous path!"

"Giggle..."

Moro covered his mouth and laughed, "Yes, Master, whatever you say goes. Righteous path or demonic path, so what? They'll all still suffer the five signs of decay. Not to mention Demon Emperors and Immortal Emperors, even gods will suffer the same fate."

Boom! Boom!

As they were talking, thunder roared across the heavens and earth, as if the end of the world had come.

This is a crucial moment for the advancement of the Heavenly Demon Tomb.

Moro hurriedly said, "Master, let's go out together. Watch me overcome the heavenly tribulation!"

"Um."

Guo Feng nodded. With the protection of the Demon Luo's aura, he was not afraid of the heavenly tribulation.

As they were talking, they flashed out of the Heavenly Demon Tomb.

As soon as he came out, he saw that Moro had transformed into a giant, like a colossal spirit god.

It exuded boundless demonic energy, enveloping Guo Feng.

Then, Moro instantly cast a series of hand seals, causing the square Heavenly Demon Tomb to suddenly shrink to a radius of several hundred meters.

Then it spun rapidly, carrying the millstone-like magic array, and rushed into the sky to clash with the terrifying heavenly lightning.

They exchanged blows thousands of times.

Finally, the thunder ended.

The Heavenly Demon Tomb shone brightly, creating a powerful shockwave and a surge of energy.

The runes on the city walls surrounding it also seemed to become clearer.

Several more dazzling black pillars appeared, seemingly engraved with the secrets of the ancient demon race.

Guo Feng knew that the Heavenly Demon Tomb had been upgraded to the level of a mid-grade immortal artifact, comparable to a low-grade holy artifact!

"What a powerful magic weapon! With just a little smash, I could kill dozens of second-grade Celestial Immortals!"

He was thrilled.

Just then, the Heavenly Demon Wormhole suddenly began to shake, as if thousands of Heavenly Demons were about to fly out.

"The Heavenly Demon has emerged, Master! The Heavenly Demon Wormhole must be destroyed now, otherwise, once the Fifth-Rank Heavenly Demon King appears, I will be captured!"

Moro hurriedly spoke, his eyes fixed on the Demon Wormhole!
