Chapter 351: The Heavenly Evil God Emerges

In a lower plane outside the Northern Desolate Hills, the Saint Heavenly Demon Emperor asked, "Is that Emperor Xiao Tian still in the Demonic Realm?"

"Yes," the Spirit Heavenly Demon Emperor nodded. "Xiao Tian's sudden attack has caused us heavy losses. To date, over a hundred Demon Emperors have perished, including several Heavenly Demon Emperors."

"Good. Since he's still in the Demonic Realm, we should seize the opportunity to rescue the Heavenly Evil God," said the Saint Heavenly Demon Emperor. "Once the Heavenly Evil God emerges, we can destroy both him and the Great Thousand World."

The Dark Heavenly Demon Emperor frowned, "Saint Heavenly Demon Emperor, I feel something is off. What if they've already set a trap, waiting for us to step in?"

"I've considered that possibility," said the Saint Heavenly Demon Emperor solemnly, "but do we have any other choice?"

All the Demon Emperors fell silent. Indeed, they had no other option. None of them could stand against Xiao Tian. If they didn't rescue the Heavenly Evil God, their fate was certain death.

The Black Corpse Heavenly Demon Emperor said gravely, "We have no retreat left. Since death is inevitable, we might as well take a chance."

"Rest assured, we aren't entirely unprepared," said the Saint Heavenly Demon Emperor. "Although the Evil Spirit Clan has been wiped out, the Heart Heavenly Demon Emperor has another plan."

The Heart Heavenly Demon Emperor laughed sinisterly, "Hehehe, the Grand Elder of the Great Thousand Palace, Qin Tian, is under my control. When the time comes, he will be our inside man, ensuring the Heavenly Evil God's escape!"

Their words greatly encouraged the other Demon Emperors. Then they tore through space, carrying boundless demonic energy, and entered the Northern Desolate Hills.

Seeing the external evil clans' Demon Emperors mobilize, the Great Thousand World's prepared forces were still taken aback.

The Green-Robed Sword Saint, holding his three-foot-long azure sword, said, "I didn't expect them to transfer a lower plane node to outside the Northern Desolate Hills without us knowing. Thankfully, the Heavenly Emperor's sudden attack disrupted their plans. Otherwise, we would have been caught off guard."

"Indeed," the True Dragon Emperor said gravely. "The external evil clans are far stronger than us, with over a thousand Demon Emperors coming!"

The Great Thousand World had only a few hundred Heavenly Sovereigns, while the external evil clans had several times that number. It became apparent that the external evil clans had been hiding their strength.

As boundless demonic energy surged, one demonic figure after another, tall as demonic gods, flew out from the void cracks, their sinister voices echoing through the heavens.

"Pups of the Great Thousand World, if you don't release our god, we'll annihilate you today!"

The demonic roars reverberated through the heavens, and demonic energy continually emerged, transforming the surrounding land into demonic territory.

"Hahaha!" The Undying Lord laughed towards the sky. "Saint Heavenly Demon Emperor, our Great Thousand World has a transcendent Heavenly Emperor. Your external evil clans will be exterminated!"

"If you won't cooperate, then be ready to be wiped out by our god!" the Saint Heavenly Demon Emperor roared, "Attack! Before the Heavenly Emperor returns, destroy them!"

At his command, the demonic shadows surged forward.

"Great Thousand Demon Formation, activate!" the Undying Lord shouted. A terrifying formation materialized, radiating boundless power.

"Ahhh!" Screams erupted as countless Demon Emperors were obliterated by the formation's power.

The Green-Robed Sword Saint sneered, "Saint Heavenly Demon Emperor, this Great Thousand Demon Formation was created by the Immortal Emperor, containing transcendent power. Did you really think you could break through?"

"This formation may be strong, but it's ultimately a dead object!" The Saint Heavenly Demon Emperor gazed at the formation covering the Northern Desolate Hills, his eyes glowing. "Corrosive Demon Clan, it's your turn. If we win this battle, we will take care of the rest of your people!"

"Yes, sir!"

At his command, numerous demonic figures emerged from the demonic energy. Their bodies were viscous, dripping black liquid that corroded even the void.

The Corrosive Demon Clan had a natural, domineering corrosive power that could erode any force.

"Roar!" The Corrosive Demon Clan roared in unison. Countless demonic lights shot out like swords. As the demonic light surged, their bodies exploded, forming a thick, black river that fell from the sky onto the Great Thousand Demon Formation.

"Sizzle!" Upon contact, black smoke rose as the formation emitted mysterious power, evaporating the black river.

"Not enough! Continue!" commanded the Saint Heavenly Demon Emperor.

"For our clan!" More Corrosive Demon Clan members exploded, their black liquid continuously pouring onto the formation. But despite their terrifying corrosive power, they couldn't break through.

The Saint Heavenly Demon Emperor's face darkened, "Heart Demon, it's your turn!"

"Yes!" A voice filled with boundless demonic power echoed as a demonic figure emerged from the demonic energy.

"You... weren't you killed by me? How are you still alive?" Seeing the figure, Qin Tian was shocked, a chill spreading through him.

"Hehehe, open the formation for our clan!" the figure laughed eerily. Countless black lights shot from him into the void.

Suddenly, Qin Tian's body trembled. He realized an eerie force was eroding him, controlling his spiritual power. "Seal me quickly, I've been controlled!" Qin Tian roared, his eyes red with resistance, but he couldn't stop it.

The Green-Robed Sword Saint and the Undying Lord moved to seal him, but four peak-stage Celestial Heavenly Sovereigns attacked them, preparing to self-destruct. Forced to protect the masses, they had to engage the attackers.

The others watched in horror as Qin Tian's trembling hands formed seals, causing the Great Thousand Demon Formation to wane.

"This is the Heart Demon Clan leader, one of our Thirty-Two Great Clans," explained the Saint Heavenly Demon Emperor. "Even the current you couldn't defeat him. The one you killed was just a heart demon seed, part of our plan. Now, you're finally useful!"

Hearing this, all the Heavenly Sovereigns felt a chill. Qin Tian, a peak-stage Saint Heavenly Sovereign, couldn't even detect the heart demon seed. This was terrifying.

They looked around warily, wondering if anyone else among them was controlled by heart demon seeds, ready to strike.

Suddenly, brilliant flames erupted from Qin Tian, exuding imperial majesty.

"That's the Heavenly Emperor's Imperial Flame!" many recognized it.

Xiao Tian emerged from the crowd, standing at the front. "Thank you, Heavenly Emperor!" Qin Tian bowed, the heart demon seed inside him burned away, restoring his control.

"We greet the Heavenly Emperor!" the Heavenly Sovereigns cheered joyfully.

"What? The Heavenly Emperor?" The external evil clans were shocked. They didn't expect Xiao Tian to be here, fearing certain death.

The Saint Heavenly Demon Emperor stared at Xiao Tian, "Don't panic. This isn't the real Xiao Tian, but an avatar with the power of a top-tier Celestial Demon Emperor!"

"Just an avatar?" The external evil clans breathed a sigh of relief. They weren't afraid of an avatar.

"I am indeed an avatar, but my true self is here!" Xiao Tian smiled, pointing to the distance.

Everyone looked and saw a graceful figure emerge from the void behind the external evil army. His presence was overwhelming, like a god before mortals.

"Impossible!" "How did he get here so fast?" "Wasn't he deep in the Demonic Realm?" "Heaven help us!"

The external evil clans panicked.

"Zheng!" Xiao Tian slashed his sword, a radiant, vast sword light tearing through the demonic clouds, killing countless demons and dozens of Demon Emperors.

"Our race is at a life-or-death moment. We must all sacrifice to revive our god!" The Saint Heavenly Demon Emperor commanded, "All Celestial Demon Emperors, attack Xiao Tian! The rest, into the formation!"

He led the thirty-two clan leaders and the Celestial Demon Emperors against Xiao Tian.

The external evil clans had over a hundred Celestial Demon Emperors, with half of the thirty-two clans being top-tier, equivalent to peak Saint Heavenly Sovereigns. But to Xiao Tian, they were mere ants.

"Slash!" Each of Xiao Tian's sword strikes killed a Celestial Demon Emperor. The Imperial Flame and Seven Great Ancestral Talismans also claimed lives, as did the Eternal Immortal Body's punches.

In moments, Xiao Tian slaughtered over a hundred Celestial Demon Emperors.

"Heavenly Evil God, your people are being slaughtered!" The Saint Heavenly Demon Emperor laughed grimly before self-destructing.

"Playing the victim? You invaded our world, and now we can't fight back?" Xiao Tian sneered, destroying him before he could self-destruct.

All the Celestial Demon Emperors perished, their remains and demonic energy sent into the void to prevent the Heavenly Evil God from using them to recover.

"Heavenly Emperor's might!" The Great Thousand World's people cheered, believing the external evil threat was finally ending.

"Attack!" They moved to kill the remaining Demon Emperors.

"Focus on the formation! We must seal the Heavenly Evil God!" Xiao Tian commanded, still killing demons.

"Yes!" The Heavenly Sovereigns poured their energy into the formation.

"Roar!" A demonic roar shook the land as the Northern Desolate Hills trembled.

"The Heavenly Evil God is breaking free! Strengthen the formation!" The Undying Lord shouted.

Everyone intensified their efforts, even Xiao Tian added power to the formation, hoping to weaken the Heavenly Evil God.

"You think another Immortal Emperor can kill me?" The Heavenly Evil God mocked. "I was sealed by choice, suppressed by the Great Thousand World. Now, with the Immortal Emperor's aura on me, I can avoid suppression. Behold my true power! Open, Five Eyes! Five-Eyed God-Slaying Diagram!"

Demonic energy surged as a black diagram appeared, with five massive evil eyes opening, filled with violence and destruction. The formation began to crumble.

A pillar of demonic energy rose, revealing a colossal demonic figure. Darkness enveloped the world, an overwhelming presence like a world-ending demon god.

"Hahaha! You can't seal me again!" The demonic laughter filled everyone with terror.

"Avatar, come!" Xiao Tian's avatar merged with him, his power reaching the half-step sovereign peak.

Sword in hand, Xiao Tian challenged, "Heavenly Evil God, let's end this!"

"Impressive, a successor surpassing the Immortal Emperor," the Heavenly Evil God said. "But you're not fully sovereign. You can't kill me. I can avoid suppression and destroy your world!"

With a blood symbol on his sixth eye, his power surged.

"Boundary-Dividing Demonic Light!" A black light split the world, isolating Xiao Tian.

"You don't know, I was the Nine-Eyed Evil God, not limited to five eyes. In eight years, I'll open nine eyes, and your world will perish!"

He vanished with his forces.

"Break!" Xiao Tian tried to shatter the barrier but couldn't.
