My disciple's cultivation returns ten thousand times, so I have to be invincible.

In the endless sky, a group of powerful emperors frowned instinctively when they heard that the two were going to the Heaven Beyond Heaven for a decisive battle.

This is because this outer heaven is not fixed, but moves.

Moreover, this place cannot be observed or explored!

This makes it difficult for them to realize their wish to reap the benefits.

The Emperor of the Underworld did not pay attention to everyone's thoughts.

But he flipped his hand and something appeared in his hand!

That was a challenge.

The challenge letter was three feet long and six inches wide, golden in color, and covered with mysterious runes.

He used his divine thoughts as a pen and signed his name on the challenge letter.

Then throw it to Zhong Qing!

The latter looked at the letter of challenge in his hand, which looked like gold but not gold, jade but not jade, and paper but not paper, and without any hesitation, he copied it and signed his name in the same way.

As Zhong Qing signed, it seemed as if some kind of ritual had been completed.

"Om..."

The challenge letter roared, and a mysterious yellow light burst out, as if it was pulling something.

A moment later, at the end of the light source, one could vaguely see an ancient battlefield emitting a vast will!

Since ancient times, two rays of light shot out from the battlefield, one of which shot towards the Emperor of the Netherworld, and the other shot towards Zhong Qing.

Pulling them towards the sky beyond the heaven.

Under the attention of everyone, the figures of Zhong Qing and the Nether Emperor completely disappeared from the end of their sight in just a moment, and were directly teleported to the battlefield outside the sky!

This battlefield is extremely large and stretches endlessly, with wisps of chaotic energy permeating the entire place.

With a breath of vicissitudes of time.

It seems to have existed for eternity.

The entire battlefield is not built with physical objects, but is constructed according to supreme rules.

In some places, you can see scarlet marks, which are traces of blood splashing, as if they are immortal and will never disappear. A strong fighting spirit emanates from the blood.

It was as if immortal heroic spirits were roaring and ancient gods and demons were fighting.

Standing on the battlefield, the whole mind will be unconsciously affected by this powerful fighting spirit, the blood will become more and more boiling, and there will be a desire to fight against heaven and earth.

"Is this the battlefield outside the heavens? It's truly extraordinary!"

Zhong Qing looked around intently.

I was slightly surprised.

Opposite Zhong Qing, a hint of bloodthirstiness flashed in the eyes of the Emperor of the Underworld.

"Zhong Qing, you can be buried here, it can be said that you died in a worthy place!"

"If you have any last words, please tell me."

"Since you have dedicated the secret treasure to me, perhaps I will show mercy and help you realize your wish."

His words revealed his strong confidence in himself.

Obviously, in his opinion, since he has reached the battlefield of Tianwai Tian, ​​everything will be settled.

Even if so many variables happen along the way, he will be the one who laughs the most to the end.

"Cut the nonsense!"

"Do it!"

Zhong Qing took a deep breath and secretly gathered his strength.

"hehe!"

The Emperor of the Underworld sneered, his eyes filled with murderous intent and a hint of evil spirit.

"You gave me the chance before, but you didn't use it."

"Now, I'll let you taste the powerful weapon I've prepared for you!"

……

"Immortal Slashing Sword!"

With a loud roar!

"Om..."

A buzzing sound erupted in the surrounding space!

A silver light shot out from the Emperor's body.

The silver light emitted a sharp cold light, illuminating the entire battlefield.

That cold light seemed to carry a murderous intent, as if it was going to penetrate through ancient history and pierce through the entire world.

This killing move is too terrifying.

It seems to be able to destroy the world and end all living beings.

This is the ultimate killer move that the Netherworld Emperor prepared for Zhong Qing!

As one of the five hall masters of Fengtian Palace, Emperor Youming has many trump cards.

And this Immortal-Slaying Sword is one of his many trump cards.

This is a semi-immortal level secret technique.

Its origin is derived from an extremely terrifying forbidden magic in ancient times - the Flying Knife that Beheads Immortals!

Once it is used, gods who stand in the way will be killed, Buddhas who stand in the way will be killed, and you will be invincible.

The Immortal-Slaying Sword was created based on the Immortal-Slaying Flying Sword.
