It was a giant demon with wings on its back and black scales all over its body. It had eight arms, a head like a tiger, sharp fangs, and a pair of eyes like a blood moon, full of bloodthirsty and hatred.
In Ling Xiao's perception, even though this Heavenly Demon King has been sealed for thousands of years, he still has combat power comparable to that of the Supreme Being, and is extremely powerful.
"kill!"
Ling Xiao had too many regrets in his heart, regrets that he missed that battle ten thousand years ago, regrets that he was not by Jinse's side, regrets that countless old friends would be gone after ten thousand years.
At this moment, all those regrets turned into overwhelming anger and fighting spirit, pouring towards the Heavenly Demon King.
The Sky-Swallowing Ancient Sword bloomed with unparalleled sharpness. Although it no longer had the spirit of the weapon, it was still as sharp as ever. In Ling Xiao's hand, it was shining brightly, and it was slashing towards the Heavenly Demon King like the Milky Way.
"You humble ant, seeking death!"
The Heavenly Demon King was also angered by Ling Xiao, spitting out obscure syllables, and his eight arms flew across the sky, like a pillar of heaven collapsing, and suppressed Ling Xiao.
In the eyes of the Demon King, although Ling Xiao looks very strong, he is just a humble ant. He dares to attack the great Demon King. He is simply looking for death.
Boom!
The sky shook, and the Heaven-Swallowing Sword was extremely sharp. When it struck the Heavenly Demon King's arm, brilliant sparks burst out. The Heavenly Demon King's arm was extremely hard, and the Heaven-Swallowing Sword could only leave a trace of white marks on it.
The Demon King vomited loudly, and a black divine light shot toward Ling Xiao, containing an edge that could penetrate everything.
Ling Xiao's whole body's blood boiled, and he performed the Four Elephants Strike Heaven Style. The four divine lights of earth, water, wind, and fire rose into the sky and turned into a fist seal of chaos. They directly scattered the black divine light and blasted towards the Demon King.
This is a collision between two worlds, without any room for relaxation. It is a life-and-death struggle from the very beginning.
Not only Ling Xiao, the other five supreme war spirits also burst out with extremely terrifying fighting power, killing the five heavenly demon kings.
"Little cubs, let me play with you!"
The old goat's eyes also became extremely blood-red. These extraterrestrial demons seemed to bring back his bad memories, and he suddenly raised the Heaven-Swallowing King Cauldron across the sky and came towards the weak demon kings to suppress them.
In the secret realm of immortality, the demonic power was vast, the divine light surged, the sky was shattered, endless chaos and mist filled the air, and a peerless war broke out!
Except for a few warriors who escaped from the secret realm of immortality, most of them died with no bones left.
Moreover, under the influence of the Huangquan Shenglong Formation, the entrance to the Secret Realm of Immortality was also shattered, and the entire Fierce Beast Mountain Range was trembling.
In the secret realm of immortality, a slovenly-looking old man, holding a big gourd, watched the peerless battle from a distance, with an extremely excited look in his eyes.
"It's been ten thousand years, it's been ten thousand years, and my mission is finally completed..."
The old man's figure slowly disappeared, accompanied by a thick sigh.
If the owners of the major holy lands were still alive, they would definitely be able to recognize this old man. He was the legendary confused old man and the most mysterious one in the entire Eight Wastelands.
The moment the confused old man disappeared, the entire Fierce Beast Mountain Range began to tremble.
Boom!
Above the void, vast thunderbolts fell, so intense that the endless creatures in the Eight Desolate Realms were trembling, feeling a fear deep in their souls.
Deep in the Fierce Beast Mountain Range, endless mist shrouded, a terrifying aura erupted, and a terrifying figure could be vaguely seen emerging.
It was surrounded by colorful chains, exuding unparalleled power of destruction, but at this moment, as if due to changes in the secret realm of immortality, those colorful chains were instantly broken.
The figure rushed out from the depths of the earth, exuding an old, vast and mysterious aura.
boom!
The void was instantly torn apart by that figure, and one could faintly see the secret realm of immortality, the scene of countless battles between demon kings.
The figure rushed into the Secret Realm of Immortality, and the Secret Realm of Immortality was instantly sealed again.
But at this moment, in the Netherworld Sect.
A young man with a strange face suddenly stood up, with a look of surprise and uncertainty in his eyes.
"The Underworld Ascension Dragon Formation has been activated. Logically speaking, those extraterrestrial demons should have been born. Why is the Secret Realm of Immortality sealed again? And what is that aura just now?"
At this moment, a strong man wearing black armor and a ferocious mask walked in from the outside, exuding a monstrous aura.
This big man turned out to be a powerful man in the princely realm!
I saw him kneeling on one knee towards the young man with a strange face, and said respectfully: "Reporting to the Ninth Holy Son, there has been a change in the secret realm of immortality, and many people have fallen into it. The whereabouts of the Netherworld King are still unknown!
"
"Explore further, I want to know what happened in the secret realm of immortality!"
The young man with a strange face, the Ninth Holy Son, had a cold light in his eyes, and his whole body exuded an aura that made the world tremble.
"yes!"
The big man said respectfully, turned around and left the palace.
"I have been planning for so long, and even handed over the Soul-Destroying Nail to you. King Netherworld, please don't let me down! Otherwise... the consequences will not be something you can bear!"
The Ninth Holy Son whispered to himself. The light around him flashed and he disappeared into the palace in an instant.
The secret realm of immortality.
The figure that came from the depths of the Fierce Beast Mountain Range descended, exuding a monstrous aura, ancient and vast, that actually overwhelmed all the extraterrestrial demons.
"Um?"
Ling Xiao's eyes flashed, and he realized that it was a tall Xuanwu statue with a dragon head and a snake body, stepping towards it in the void.
There are mysterious symbols on the turtle's back, which emit bright light, as if expounding some kind of truth about heaven and earth.
roar!
As soon as this Xuanwu appeared, he roared loudly, and the surrounding void shattered into pieces, as if a storm had set off.
There was a black ocean emerging behind it, and every drop of sea water rose into the sky, turning into a brilliant sword light, shooting toward the overwhelming outside demons below.
Phew! Phew! Phew!
Countless extraterrestrial demons died in Xuanwu's hands, and even the six demon kings were pierced by the incomparable sword light, leaving traces of blood.
"Is this Xuanwu really the Xuanwu beast from ancient times?"
Ling Xiao's eyes flashed. Although this Xuanwu looked like he had just entered the Supreme Realm, his terrifying combat power was not even weaker than that of the Titled Supreme.
Although the six heavenly demon kings were very powerful and powerful in their heyday, they have been suppressed for thousands of years and their current strength is less than one hundred.
Ling Xiao and other six supreme war spirits are only evenly matched against the six heavenly demon kings, and as time goes by, the power of the war spirits will become weaker and weaker. By then, maybe these six heavenly demon kings will really fight.
Escaping from the secret realm of immortality, he began to wreak havoc on the world.
