Just as True Martial Star stood on the verge of destruction, everyone shut their eyes involuntarily, unable to witness what was about to unfold. After all, the moment the impact struck the planet, it would reduce all life to ashes.

The Grand Unity Sect had abandoned every moral boundary in pursuit of its goal, going so far as to sacrifice hundreds of millions of lives just to kill Liu Wuxie.

However, when the Great Divine Sun Bell was about to crash into True Martial Star, an even more powerful force appeared, hovering in the sky and illuminating the world. The aura of that immortal artifact was so overwhelming that it seemed capable of destroying everything.

After refining an immortal, Nightmare City had risen several levels and become even stronger than ordinary immortal artifacts. After all, Nightmare City had once retained many imprints belonging to Spirit Child, and those restraints had unraveled after his death.

Without Spirit Child's restraints, Nightmare City could now grow without fear.

"It's another immortal artifact!" The moment Nightmare City appeared, heaven and earth split apart, and countless people felt as though their eardrums had burst. Blood flowed from their eyes, ears, nose, and mouth.

No one had expected two immortal artifacts to appear at the same time. Even quasi-immortals could not withstand the laws released by those immortal artifacts, and many of them coughed up blood under the force of the shockwave.

Golden light enveloped the entire True Martial Star and prevented the Great Divine Sun Bell from advancing even another inch. The battle had turned into a direct clash between immortal artifacts.

"That doesn't look like the Heavenly Dragon Sect's Radiant Mirror!" Various sects were familiar with one another's immortal artifacts, and everyone knew the Heavenly Dragon Sect's Radiant Mirror well.

Back during the Myriad Race Ceremony, the Radiant Mirror had used only a projection to shatter the Great Divine Sun Bell's attack with ease.

"It's Nightmare City! Liu Wuxie took control of it and even upgraded it into an immortal artifact!" Someone finally recognized the origin of the second immortal artifact. No matter how much Liu Wuxie had altered it, the internal structure had never changed. It had merely become a miniature version of what it once was.

The last surviving elder of the Grand Unity Sect was filled with grief. Just as he thought the Great Divine Sun Bell would destroy True Martial Star, another immortal artifact appeared. Who could have anticipated that Liu Wuxie also possessed an immortal artifact?

Logically speaking, forging an immortal artifact should have caused a great commotion, yet the four astral domains had remained calm over the past few years. No new immortal had appeared, and no new immortal artifact had announced its birth.

What they did not know was that Nightmare City had advanced to an immortal artifact within the desolate world, hidden entirely from outsiders. That secrecy had caught his enemies by surprise, just like he had planned.

Liu Wuxie finally made his move. From the instant the Great Divine Sun Bell had arrived, he had decided to teach it a brutal lesson with the help of the Nightmare City, even if he could not destroy it outright.

The heavens and earth trembled when the two immortal artifacts collided, and the resulting shockwaves destroyed an entire mountain range.

The fusion of immortal runes accelerated True Martial Star's growth even further. At its current pace, True Martial Star had already become comparable to a first-tier planet, and it could advance to a super planet in only a few years at most.

That terrifying rate of growth left countless people stunned. The destroyed mountain ranges began reconnecting and reshaping into even larger ranges.

Nightmare City suddenly expanded, shielding True Martial Star and blocking the Great Divine Sun Bell from advancing any farther.

"Nine Absolute Fist!" Liu Wuxie did not hesitate and threw out his punch, releasing a devastating force that formed into a golden river above the sky.

The sheer destructive might of that attack left everyone's breathing ragged. Many people hadn't witnessed Liu Wuxie kill the Spirit Child firsthand.

When that force swept outward, it released a dazzling brilliance. It was not the strike of a mortal. It felt as though an immortal had truly returned.

The surrounding space had long since vanished, turning into a world of chaos, while boundless void winds swept in from the distant reaches of creation.

The Great Divine Sun Bell began to spin, releasing a terrifying force that neutralized Nightmare City's pressure. As expected of an old immortal artifact, its foundation far surpassed Nightmare City's.

Although Nightmare City could not compare to it in terms of foundation, laws from the celestial realm had nourished it, making it far more terrifying in terms of offensive power.

Under the crushing suppression of the Nine Absolute Fist, the Great Divine Sun Bell released a resonant echo that swept out like a shockwave.

The cultivators gathered in the surroundings suffered ruptured internal organs, dyeing the sky red with their blood.

"Quick, retreat!" Mortals were no longer qualified to remain involved in a clash between immortal artifacts. Even so, that shockwave had only managed to destroy a portion of the Nine Absolute Fist's power.

"Hmph! It's only an immortal artifact," Liu Wuxie said as he looked down upon the heavens, righteous aura erupting from his body.

The power of the Nine Absolute Fist, combined with more than four hundred thousand immortal runes, was beyond imagination. How could an ordinary immortal artifact possibly withstand it?

The Great Divine Sun Bell let out a mournful cry the moment the Nine Absolute Fist struck it. Its golden radiance dimmed at once, and visible cracks began spreading across its surface. Liu Wuxie had nearly shattered it with a single punch.

At that very instant, Nightmare City moved. It transformed into a streak of light and smashed into the Great Divine Sun Bell once more. Two forces struck together, and Liu Wuxie clearly intended to destroy the Great Divine Sun Bell outright.

It would be equivalent to stripping away an immortal's protection over the Grand Unity Sect, and he could then seize that opportunity to destroy them in one fell swoop.

With a thunderous impact, Nightmare City slammed into the Great Divine Sun Bell, shaking heaven and earth. Even the Laman Astral Domain, the Martial Spirit Astral Domain, and the Blood Fiend Astral Domain felt the violent collision.

The rotation speed of the Indigo Bamboo Astral Domain accelerated as countless rooftops collapsed and cracks spread through buildings. A clash at the level of immortals had already affected all four astral domains.

It was no wonder that every upheaval in heaven and earth would bring about the deaths of countless people, but it would also grant countless others a chance to rise.

All the cultivators on True Martial Star broke through to the next level. As the planet advanced, everyone benefited from the power that flowed back into them.

From this moment onward, those cultivators would have to do their utmost to protect True Martial Star. Otherwise, the planet itself would punish them.

The Great Divine Sun Bell released a creaking sound as the crack at its crown expanded even further. Damage to an immortal artifact was never easy to repair, and unless it underwent tens of thousands of years of recovery, restoration would be impossible.

At last, the Great Divine Sun Bell transformed into a streak of light and fled. It was no match for the combined assault from Liu Wuxie and Nightmare City. It fled as quickly as it had arrived and vanished from sight in the blink of an eye.

"Do you think you can escape? I'll still destroy you even if you flee all the way back to the Grand Unity Sect," Liu Wuxie roared. He did not pursue the immortal artifact. Instead, a cruel smile spread across his lips.

The moment the crowd saw that smile, a chill ran down their spines. They all knew that Liu Wuxie intended to begin a massacre.

Since the Grand Unity Sect had made the first move, he would naturally return the favor. There was no possibility of reconciliation between the two sides, which meant he no longer had any reason to hold back.

Shi Qian and the others killed the final surviving elder of the Grand Unity Sect. Once the battle ended, everyone returned to Nightmare City, and the city reentered the desolate world.

"Grand Unity Sect, wash your necks clean and wait for death," Liu Wuxie declared as he licked his lips. After spending a short time calming the members of the Liu Clan, he turned into a streak of light and shot toward Indigo Bamboo Star.

"Is Liu Wuxie going to attack the Grand Unity Sect? Let's go and take a look!"

The Grand Unity Sect had nearly destroyed True Martial Star and tried to slaughter the entire Liu Clan. There was no way Liu Wuxie would let that pass.

Liu Wuxie led both teams toward the Grand Unity Sect.

When Dong Wu received the news, it shook him to the core. The Grand Unity Sect's use of an immortal artifact had already enraged countless people, as battles in the mortal realm should never have escalated to the point of involving immortal artifacts.

The moment the Grand Unity Sect unleashed its immortal artifact, the four astral domains fell into complete chaos.

The Grand Unity Sect had already received the news. When the Great Divine Sun Bell returned to the sect, it went dormant. It would require a long recovery period before anyone could use it again.

Liu Wuxie needed only two hours to appear above the Grand Unity Sect, and by then, hundreds of thousands of cultivators had already gathered in the surroundings.

Three hundred thousand years ago, the Grand Unity Sect had launched a surprise assault against the Heavenly Dragon Sect. Three hundred thousand years later, Liu Wuxie had led experts from the Heavenly Dragon Sect and the Heavenly Dao Society to attack the Grand Unity Sect in return, an eye for an eye.

The same scene had unfolded again after three hundred thousand years. The only difference was that the Heavenly Dragon Sect had now arrived with overwhelming force. In contrast, the Grand Unity Sect had succeeded back then only through a surprise assault that had caught the Heavenly Dragon Sect off guard.

The Grand Unity Sect had already activated its strongest defensive array, one so powerful that even an immortal would struggle to break through it.

Months earlier, the Grand Unity Sect had begun contracting its territory and recalling all experts stationed outside in preparation for a possible surprise attack from the Heavenly Dragon Sect.

"Grand Unity, old dog, come out and die!" Liu Wuxie's voice made the entire defensive array tremble violently.

Countless experts of the Grand Unity Sect stood on the martial field and stared up at the sky, every one of them wearing a grave expression. The damage to the Great Divine Sun Bell had sharply weakened their overall strength.

That meant no one could stop Liu Wuxie's advance unless the immortals returned.

Liu Wuxie's voice was infused with soul energy, producing a terrifying shockwave that easily tore through the Grand Unity Sect's defensive array and entered the sect itself.

"ARGH!" Screams erupted everywhere as disciples of the Grand Unity Sect fell. Unable to withstand the power of Liu Wuxie's soul energy, they exploded one after another.

In just a single breath, more than ten thousand disciples of the Grand Unity Sect had died, and the whole world fell into deathly silence. Everyone had been horrified by Liu Wuxie's method of slaughter, using nothing but a single roar to kill so many people.

Today, Liu Wuxie had come for only one reason—to wipe out the Grand Unity Sect and erase it from the Indigo Bamboo Star forever.

The elders of the Grand Unity Sect could only watch helplessly as their disciples died. Having anticipated such a scenario, they had already prepared to fight Liu Wuxie to the death the moment they unleashed the Great Divine Sun Bell.

However, they had never expected Liu Wuxie to kill an immortal and forge Nightmare City into an immortal artifact. That was their fatal miscalculation.

They had already deduced that the Heavenly Dragon Sect would face a calamity, and that was why they had dared to commit such a monstrous act. But who could have guessed that things would end up like this?

"Liu Wuxie, you demon! What sins have these ordinary disciples committed for you to kill them?!" The Grand Unity Sect had suffered a devastating blow from the deaths of more than ten thousand disciples, and it would not recover anytime soon.

After all, those disciples were the sect's foundation and future. Yet Liu Wuxie had exterminated them without hesitation.

"And what crime did True Martial Star and its inhabitants commit? And the Liu Clan? Why did the Grand Unity Sect try to kill them all?" Liu Wuxie asked three questions in succession, leaving everyone from the Grand Unity Sect speechless.

If Liu Wuxie had not prepared in advance, True Martial Star would have already been destroyed, and every living being on it would have died. The Grand Unity Sect, therefore, had no right to question Liu Wuxie, much less denounce him as a demon.
