Demonic roars resounded between the heavens and earth with torrential demonic aura endlessly gushing out, practically turning the North Desolate Grave into a demonic domain.
As the demonic aura soared, powerful demonic beings could be seen standing within with cold gazes, looking at the Heavenly Sovereigns in the North Desolate Grave as if they were looking at their prey.
When the Heavenly Sovereigns in the North Desolate Grave saw the demonic aura, they panicked with nervousness on their faces. After all, this was the first time that they've seen such a scale of the Fiend Clans. Furthermore, those that could come here were all powerhouses.
Qin Tian, the Azure Sword Saint, and the Undying Lord's faces were cold as they looked at the demonic beings and coldly said, "Your Fiend Clans are truly daring to come so deep into my Great Thousand World. Aren't you afraid of being annihilated by my Great Thousand World?"
Demonic Qi surged in the empty space. Finally, it swiftly gathered together and transformed into a black-robed human figure. That human figure had an endless evil aura surging around him, making him appear like the ruler of the devils. However, his face was filled with a benevolence that bemoaned the state of the universe and pitied the fate of mankind. This was especially the case with his eyes. Just by looking at him, one would be unable to feel any enmity within one's heart. In fact, one would even feel an impulse to worship him.
"Haha, the North Desolate Grave has already been sealed the moment we appeared. So even if we cause a commotion here, it won't be able to spread out."
The black-robed silhouette smiled with a sacred gaze as he looked at Qin Tian's group of three. "The three of you, if you can release my deity, my Fiend Clans can share peace with the Great Thousand World."
"Saint Sky Monarch!"
Qin Tian's gaze sank as he looked at the black-robed silhouette. He had instantly recognised the latter's identity. This was the sovereign of the Fiend Clans, and his status was only beneath Tian Xie. It looked like the Fiend Clans had turned out in full force to save Tian Xie.
"You evil races are cruel and heartless. You view the people of my Great Thousand World as grass. You're simply making a fool out of yourselves by talking about peace." The Undying Lord's tone was ice-cold.
The Saint Sky Monarch casually smiled. "The strong preys on the weak, that's the unchanging truth. If my Fiend Clans want to survive, we naturally have to occupy your Great Thousand World and pollute the disgusting Spiritual Energy, replacing it with evil aura. As long as you guys are willing to submit, I can change your demonic physiques to adapt to the new Great Thousand World."
"Evil demon, how dare you pollute the Spiritual Qi of my Great Thousand World!"
Many Heavenly Sovereigns' faces changed as they hollered. One must know that the Spiritual Energy between the heavens and earth was the foundation of cultivation in the Great Thousand World. If it was tainted, then even Heavenly Sovereigns would suffer a lack of Spiritual Energy and lose their years of cultivation.
The Fiend Clans were trying to sever the foundation of the Spiritual Energy in the Great Thousand World.
Holding onto his sword, the Azure Sword Saint raised his head and smiled at the Saint Sky Monarch. "Evil clans, don't have any wishful thinking. Go back to where you came from. We will not allow you guys to dip a finger in the Great Thousand World."
"It looks like you guys aren't interested in my suggestion. Since that's the case …" The Saint Sky Monarch felt a little regretful.
After a brief pause, his eyes, which were filled with benevolence and divinity, coldly flickered as he continued, "Then I can only cleanse all of you aboriginals."
"Haha, Saint Sky Monarch, you should have thought of this from the start. What's there to talk about with the aboriginals of the Great Thousand World? Why don't you just subdue them and turn them into your slaves?"
The Saint Sky Monarch's voice resounded as a demonic aura gathered around him, forming into demonic figures with black vortexes in the lead. It was the Patriarch of the Sky Demon Clan.
At this moment, he was looking at the Heavenly Sovereigns in the North Desolate Grave with his scarlet tongue licking his lips like a hungry wolf that had seen a rabbit.
"How arrogant. Do you guys really think that you can get through this array?" Maha Tian sneered.
The Fiend Clans came in a ferocious manner, but they did not make a move. Evidently, they were fearful of the Great Thousand Demon Extinguishing Array that was left behind by the Immortal Emperor. This array contained boundless power, and any Fiend Clans that intruded would be annihilated by the array.
The Saint Sky Monarch lowered his head and looked at the massive array that enveloped the North Desolate Grave with a dark light flickering in his eyes. A brief moment later, he gently sighed, "But I never expected that there would be someone like the Immortal Emperor in the Great Thousand World."
Shaking his head, he sighed, "No matter how powerful this array is, it's still a dead object. I'm afraid that you guys are too naïve to think that you can rely on this array to protect the peace of the Great Thousand World."
As he spoke, he waved his hand and his emotionless voice resounded, "Corrosion Demon Clan, make your move."
Along with his voice, the demonic aura surged from the spatial crack and countless demonic silhouettes were revealed. Those demonic silhouettes had viscous bodies that were constantly dripping with black liquid. When the liquid dripped, it had even corroded space.
The Corrosion Demon Clan was born with a corrosive ability that was extremely domineering. Anything that came in contact with them would be gradually corroded. Roar!
Roar!
The countless demonic shadows let out low roars, and in the next instant, demonic light sputtered from their bodies like sharp swords shooting out from their bodies.
Boom!
As the demonic radiance swept out, those demonic figures started to explode with droplets of viscous black liquid that slowly rose into the air.
That black liquid was incomparably dark as it slowly flowed. However, even space couldn't bear the pressure of it as a terrifying power was vaguely being emitted, as if it could corrode anything.
Rustle!
Droplets of corrosive liquid gathered together, forming into a black stream that descended from the sky and landed on the membrane of the Great Thousand Demon Extinguishing Array.
Sizzle!
When the two of them came into contact, smoke rose into the air. The barrier of light that contained mighty power flashed and ripples appeared. A mysterious mighty power swept out and quickly purified the black stream.
"Huff."
When the Heavenly Sovereigns saw this scene, they inwardly felt relieved. It looked like the defensive capability of the Great Thousand Demon Extinguishing Array had exceeded their expectations.
"Continue!"
The Saint Sky Monarch's face did not change as he indifferently said.
"For our clan!"
Behind him, the demonic figures of the Corrosive Demon Clan roared before they started to self-destruct. Instantly, the black liquid soared into the sky and formed into a stream that endlessly poured towards the Great Thousand Demon Extinguishing Array.
Sizzle!
Sizzle! But no matter how terrifying the corrosive force was, it was still purified by the Great Thousand Demon Extinguishing Array without any damage to the membrane.
However, the Saint Sky Monarch had not noticed this scene and continued to order the Corrosive Demon Clan to self-destruct.
Mu Chen knitted his brows at this scene. After a long while, his pupils suddenly narrowed and he hollered, "They're exhausting the energy of the array to delay the formation of the spears!"
Hearing Mu Chen's holler, the hearts of Qin Tian, the Azure Sword Saint, and the Undying Lord trembled as they swept their gazes over. Indeed, they realised that the time required for the spears to form was gradually being extended!
In the past, it only took an incense's time for it to form. But right now, it had been extended by nearly half.
Evidently, the reason why the Fiend Clans were using the black liquid to corrode the Great Thousand Demon Extinguishing Array wasn't to melt the barrier, but to buy more time for them.
"Everyone, increase your Spiritual Energy!" Qin Tian hollered.
When the Heavenly Sovereigns heard his words, they immediately sat down and circulated their Spiritual Energy into the coffins.
Looking at the torrential demonic aura, the Undying Lord said, "The Fiend Clans are truly insane. To break the seal, they're actually willing to sacrifice the lives of an entire clan."
The Corrosive Demon Clan was clearly treated as a sacrifice. Such a vicious method made everyone feel a chill in their hearts.
"If this goes on, it will turn into a war of attrition. The Fiend Clans came ferociously, and they're stronger than our Great Thousand World, to begin with. Right now, the North Desolate Grave has yet to gather the strongest forces of our Great Thousand World." The Azure Sword Saint said, "If this goes on, I'm afraid that there will be a flaw."
Qin Tian's gaze flickered as he said, "No matter what, we have to hold on until the ninety-nine spears fall. As long as Tian Xie's life imprint is erased, the Fiend Clans won't be able to make a comeback."
"They're trying to exhaust the array to delay the formation of the ninety-nine spears. The three of us can make a move to buy time for the array."
"Alright." The Azure Sword Saint and Undying Lord briefly pondered before they nodded their heads.
Whoosh!
As soon as their voices rang out, they turned into three streaks of light that soared into the sky and landed on the light membrane.
Boom!
Boundless Spiritual Energy swept out. Akin to gigantic waves that blotted the skies, it caused the three streams of darkness that were whistling over to scatter.
"The three of you want to fight my Fiend Clans?" The Saint Sky Monarch sneered as he waved his hand.
As he waved his hand, six silhouettes slowly walked out from the dense demonic aura behind him. The demonic aura blotted out the sun and brought along boundless demonic might.
In the North Desolate Grave, Mu Chen and the rest looked at the six demonic silhouettes with a slight change in their eyes. The six of them were comparable to Late Phase Saint Heavenly Sovereigns.
"We're also prepared to help!" Maha Tian said to the four Patriarchs of the Ancient Clans.
"No, we have to ensure that the Great Thousand Demon Extinguishing Array has sufficient Spiritual Energy to maintain the formation of the ninety-nine spears!" Mu Chen locked his brows together.
Qing Yanjing nodded her head as well. "Don't be rash!"
The Great Underworld Ancestor of the Ancient Spirit Clan, Patriarch Hei Tian of the Ancient Abyssal Clan, and Huang Qiu of the Ancient Desolate Clan briefly hesitated before they nodded their heads. Indeed, they had to kill Tian Xie right now.
When Maha Tian saw this, he snorted and no longer spoke, since he knew what was more important.
"Haha, I'll use the lives of the three of you to welcome the appearance of my god!"
The six demonic silhouettes stood in the heavens and earth with demonic roars. Boundless demonic might enveloped towards Qin Tian, the Azure Sword Saint, and Undying Lord.
Behind them, there were several demonic silhouettes looking at Qin Tian's group of three with cold gazes.
Qin Tian, the Azure Sword Saint, and Undying Lord looked at those demonic silhouettes with cold gazes without any fear. However, the Spiritual Energy around them started to surge, causing the heavens and earth to tremble.
"Kill!"
The six demonic silhouettes roared as they pounced towards Qin Tian's group of three.
Roar!
But in that instant, an ear-deafening draconic roar resounded between the heavens and earth. A golden beam tore through the demonic aura and formed into a purplish-golden dragon that coiled in the sky with a boundless draconic might soaring between the heavens and earth.
"Haha, Brother Qin, my Divine Beast Clan is also a part of the Great Thousand World. So how can we not participate in this matter?!"
As the purplish-golden dragon covered the sky, a multicolored radiance swept out with massive silhouettes flying over. Those were the Supreme Divine Beasts of the Great Thousand World.
In the North Desolate Grave, Mu Chen and the other Heavenly Sovereigns looked at those Supreme Divine Beasts with joy in their eyes. The Divine Beast Clan of the Great Thousand World had finally arrived!
