Where there is sin, there is the Heavenly Demon Sect.

From the moment Gu Qingfeng resolved to walk the demonic path, the entire Cangming Realm underwent earth-shattering changes due to his decision.

Countless disciples of the Heavenly Demon Sect poured out like a raging flood, sweeping across the hundred thousand domains of the Cangming Realm.

Yin Demon Sect

The disciples of the Yin Demon Sect, who had been striving diligently for their future and painstakingly refining Yin Demons, saw their peaceful and idyllic lives shattered at high noon on a sunny, breezy day by a group of black-robed figures.

These black-robed figures bore the insignia of the Heavenly Demon Sect. They barged into the Yin Demon Sect with reckless arrogance, plundering all the Yin Demons, along with various dark artifacts and demonic cultivation techniques.

The Yin Demon Sect resisted desperately—and then perished.

......

Ten Thousand Ghost Cave

This was a notorious paradise for vengeful spirits in the Cangming Realm, home to countless ghosts and the Ten Ghost Kings—a place where the living dared not tread.

Yet again, on a sunny, breezy noon, a group of black-robed figures stormed in without hesitation, capturing every ghost in sight and looting every treasure they encountered. Wherever they passed, it was as if a swarm of locusts had descended, leaving nothing behind.

The pitiful Ten Ghost Kings were beaten beyond recognition before having soul-binding chains looped around their necks and dragged away.

Even their palaces, long tainted by ghostly energy and shrouded in gloom, were dismantled and carried off by the black-robed intruders.

......

Nine Venomous Shadow Serpent Territory

Here resided a group of peaceful little snake demons who spent their days producing venom, spitting toxins, turning thriving lands into wastelands, and occasionally feasting on the results.

They were so unassuming—until one sunny afternoon, when a group of black-robed figures suddenly appeared. They were powerful, wicked, numerous, and utterly unreasonable.

They yanked out every single fang from the little snake demons.

For months, demonic factions and malevolent races across the Cangming Realm suffered the same fate. The Heavenly Demon Sect’s massive operation cast a shadow over the entire realm, leaving it trembling in fear.

No one knew what the Heavenly Demon Sect was planning or why they were attacking so many factions without reason.

But gradually, people noticed a pattern—the ones targeted were all notorious, wicked organizations known for their atrocities.

This revelation stunned everyone. What was the Cangming Realm’s most infamous evil faction doing?

Could they actually be… punishing evil and upholding justice?

It seemed impossible.

Then one day, a group of black-robed figures besieged a renowned righteous sect—the Righteous Path Sect.

Just as everyone assumed the Heavenly Demon Sect had finally revealed its true colors, it turned out they had only captured the sect’s leader.

And the reason for the arrest was even more shocking.

The Righteous Path Sect’s leader had secretly been cultivating the Nine Mothers and Sons Yin Demon Soul-Devouring Grand Technique.

This revelation left the entire realm dumbfounded. Was this still the same Heavenly Demon Sect—infamous for its cruelty, wickedness, and boundless evil?

This was practically a holy sect enforcing justice!

Wherever there was evil, the Heavenly Demon Sect appeared.

A complete reversal from before, when evil followed wherever the Heavenly Demon Sect went.

The Heavenly Demon Sect’s demon-slaying campaign lasted an entire year.

This year became known as the darkest hour for demonic factions.

As one anonymous Nether Sect leader lamented: "Gu Qingfeng single-handedly set back the demonic path’s progress in the Cangming Realm by a hundred thousand years!"

During this year, the Cangming Realm became a place of sunlight and beauty, where evil could no longer hide.

Once-feared demonic cultivators, evil spirits, and malevolent races were reduced to rats in the sewers, hunted so relentlessly by the Heavenly Demon Sect that they dared not show their faces.

Statistics showed that within just one year, over a hundred demonic sects collapsed, countless demonic cultivators were arrested or left unemployed, and several evil races faced extinction. The demonic path was filled with wails of despair.

......

Heavenly Demon Sect Headquarters

Gu Qingfeng’s grand hall was filled with over ten thousand demonic cultivation manuals.

Blissful Zen, Five Desires Demon Art, Great Soul-Dissolving Technique, Ten Thousand Desires Demon Art, Supreme Yin Ghost Script, Yin Demon Scripture, Nine Heavens Yin Demon Grand Technique, Nine Mothers and Sons Yin Demon Soul-Devouring Grand Technique, Heavenly Demon Shattering Form Grand Technique, Nine Nether Reincarnation Burial Art, Poison Torture Bone-Locking Heart-Piercing Asura Technique, Nine Nether Demon Art, Asura Demon Art…

Virtually every infamous demonic technique in the Cangming Realm was gathered here—each more sinister than the last.

If a manual didn’t involve blood, souls, or killing a few people for cultivation, it wasn’t even worthy of being in this hall.

Some of the more powerful demonic manuals bore Dao patterns, occasionally leaking traces of demonic energy and bloody light, turning the entire hall into a nightmarish inferno.

Aside from the manuals, Gu Qingfeng also had before him a golden ancient cauldron—the Fire Emperor Cauldron, an imperial weapon once belonging to the Qilin Child’s ancestor, the Qilin Ancient Emperor.

Inside the cauldron boiled a concoction of sinister substances—demonic energy, fiendish aura, ghostly essence—all plundered from various demonic factions. The convergence of these malevolent forces rendered the surrounding ten thousand miles barren, as though a hellscape had manifested.

But that wasn’t all. Gu Qingfeng also sought out Little Corpse Charm.

Little Corpse Charm possessed the bloodline of a Corpse Emperor, growing stronger by drinking blood.

To ensure absolute success, Gu Qingfeng had her consume the blood of countless demons, demonic cultivators, and evil races, fusing their essence into her own power.

With everything prepared, Gu Qingfeng began comprehending the essence of the demonic techniques, then merging them together.

Demonic techniques were inherently extreme, making them difficult to reconcile with one another. Forcing them to merge could trigger catastrophic consequences—but Gu Qingfeng didn’t care.

He forced the fusion anyway.

Three months later.

Having extracted the essence of ten thousand demons and relying on his profound understanding of fiends and his astonishing comprehension, Gu Qingfeng finally created a new demonic art—the Limitless Demon Art.

The sinister concoction in the Fire Emperor Cauldron had also finished refining. Normally, such malevolent substances were nearly impossible to fuse and purify, but the Fire Emperor Cauldron, being an imperial weapon, proved more than capable. After three months of boiling, it produced a thick, bubbling, indescribable green broth.

Little Corpse Charm was also ready. Over this period, she had consumed the blood of at least several hundred thousand demons and other races—even throwing up several times from the sheer volume.

Thanks to her efforts, her power had skyrocketed, and her own Dao had undergone a bizarre transformation.

Originally, Little Corpse Charm had reached the Quasi-Emperor realm by absorbing the blood of another Quasi-Emperor, inheriting their Dao.

Since she excelled in charm and illusion, Gu Qingfeng had specifically captured a Quasi-Emperor demon who cultivated the path of illusions for her to devour.

Thus, her Quasi-Emperor Dao had been the Dao of Illusions.

But after assimilating the blood of hundreds of thousands of demons and evil beings, her Dao mutated into something entirely new—a strange, ever-shifting, and supremely sinister path.

She named it the Thousand Illusions Demon Dao.

......

"Little Corpse Charm, once I drink this green broth, you must attack me with everything you have. Push your Thousand Illusions Demon Dao to its absolute limit—do you understand?" Gu Qingfeng said solemnly, holding the Fire Emperor Cauldron.

The Little Corpse Charm nodded earnestly and let out a soft hum of agreement.

Huff!

Gu Qingfeng took a deep breath, his expression strained and hesitant as he stared at the pot of soup brewed from the most sinister ingredients in the world.

To put it bluntly, this soup was so lethal that even a Quasi-Emperor would drop dead after a single sip. A Supreme Being would ascend to eternal bliss from just a whiff, and a Celestial Venerable? The moment they stepped within a hundred miles, their orifices would bleed, and they’d be foaming at the mouth.

Gu Qingfeng wasn’t afraid of the soup’s toxicity—after all, he had his system and the Sin of Ultimate Defilement to rely on. No, what truly disgusted him was its appearance. It looked like the greenish excrement of someone who’d eaten nothing but spinach for a week.
