Devouring demons, I attain immortality.

Several days later, in Jinzhou City.

Lin An had mostly recovered. He stood on the city wall, gazing at the distant horizon. Although Zi Yan was dead, his dying words still lingered in Lin An's mind.

He knew that the real threat might not yet be coming.

Just then, Xuan Fengzi and Liu Zhanshu approached. Xuan Fengzi's expression was solemn, and he said in a low voice, "Young friend Lin An, we have just received news that the forces of extraterrestrial demons have begun to appear in other places. The major sects have united to prepare for the joint resistance against the demon invasion."

Liu Zhanshu also said in a deep voice, "Lin An, your strength far surpasses that of ordinary people. We hope that you can join our alliance to fight against the extraterrestrial demons together."

Lin An nodded and said without hesitation, "Seniors, it is my duty. The extraterrestrial demons are the enemy of the entire Great Qian Dynasty, and I will do my utmost to help them."

Xuan Fengzi nodded with satisfaction: "With you joining us, our chances of winning have increased significantly."

Just then, a series of hurried footsteps suddenly came from afar.

A young cultivator dressed in blue robes rushed over, his expression panicked, and said, "Lord Xuanfengzi, Lord Liu, something terrible has happened! We just received news that the vanguard of the extraterrestrial demons has breached Tianfeng City in the north and is heading towards our Jinzhou City!"

"What?!" Xuan Fengzi and Liu Zhanshu exclaimed in surprise at the same time.

A cold glint flashed in Lin An's eyes, and he said in a deep voice, "It seems that the extraterrestrial demons are moving faster than we expected."

Xuan Fengzi quickly calmed down and said in a deep voice, "Immediately notify all the major sects to prepare for battle! Young friend Lin An, City Lord Liu, we must go to the front lines immediately and stop the extraterrestrial demons' offensive!"

Lin An nodded, gripping the Nine-Turn Demon-Slaying Blade tightly, his eyes blazing with fighting spirit: "Let's go, let's go and meet these extraterrestrial demons!"

In the north, the city defenses of Jinzhou.

A massive, dark army of demons surged in like a tidal wave, leaving nothing but desolation in their wake.

In the sky, dozens of enormous demons circled, emitting piercing screechs.

The earth trembled under the trampling of the demon army, as if the end of the world had arrived.

Lin An, Xuan Fengzi, and Liu Zhanshu stood on the city wall, looking at the approaching demon army in the distance, their expressions solemn.

"The number of these demons far exceeds our expectations," Liu Zhanshu said in a deep voice.

Xuan Fengzi nodded: "It seems that the extraterrestrial demons have come out in full force."

Lin An gripped the Nine-Turn Demon-Slaying Blade tightly, a resolute glint in his eyes: "No matter what, we cannot allow them to advance another step."

Just then, a deafening roar suddenly came from the demon army.

A gigantic demon emerged from the army, its body as large as a mountain, its body shrouded in thick black mist, like a demon god from hell.

"That is... the vanguard general of the extraterrestrial demons, Black Fiend!" Xuan Fengzi's expression changed, and he whispered.

As a second-rank admiral of the Great Qian Demon Suppression Division, he was well-versed in information about extraterrestrial demons.

Black Fiend raised his head, his scarlet eyes fixed on Lin An and the others on the city wall, and let out a deafening roar: "Insects, prepare to die!"

Lin An sneered, meeting Hei Sha's gaze without fear: "Hei Sha, today is your death day!"

Before he finished speaking, Lin An flashed and leaped off the city wall, rushing towards Hei Sha.

Seeing this, Xuan Fengzi and Liu Zhanshu followed without hesitation.

A great war is about to break out!

Lin An was extremely fast, and in the blink of an eye, he rushed to Hei Sha's side.

The Nine-Turn Demon-Slaying Blade in his hand shone brightly with golden light, and he slashed towards Hei Sha's head. Hei Sha roared and slammed his enormous hand down on Lin An, attempting to smash him into a pulp.

However, Lin An moved with ghostly agility, easily dodging Hei Sha's attacks.

The Nine-Turn Demon-Slaying Blade in his hand slashed fiercely at Hei Sha's arm, golden light and black energy intertwined, emitting a deafening roar.

Black Fiend let out a painful roar as the black aura on its arm was swallowed by the golden light of the Nine Revolutions Demon-Slaying Blade, revealing its stark white bones. It frantically swung its other arm, trying to repel Lin An.

However, Lin An was too fast. He was like a golden lightning bolt, constantly weaving around Hei Sha, leaving a deep wound on Hei Sha's body with each strike.

Xuan Fengzi and Liu Zhanshu were not idle either. They attacked Hei Sha from both sides, their spiritual light and sword energy intertwining, forcing Hei Sha to retreat step by step.

"roar!"

Black Fiend let out a defiant roar, its black energy surging wildly as it attempted a final struggle. However, Lin An would not give it any more chances.

"Power of Devouring, break!"

Lin An let out a low shout, and the golden light on the Nine Revolutions Demon Slayer Blade instantly surged, transforming into a huge blade of light that slashed directly at Hei Sha's head.

"No!"

Black Fiend let out a shrill scream as its massive head was severed by the golden light. Its enormous body crashed to the ground, turning into a cloud of black mist and vanishing without a trace.

The fall of Heisha seemed to toll a death knell for the army of demons.

The once-aggressive vanguard of the demons was now thrown into brief chaos.

Lin An, Xuan Fengzi, and Liu Zhanshu stood in the center of the battlefield, emanating a powerful aura that intimidated the surrounding demons.

However, the demon army was simply too large in number. After a brief period of chaos, they regrouped and surged toward Jinzhou City.

The demons circling in the sky let out piercing screechs as they swooped down, attempting to tear apart the defenses on the city walls.

"We mustn't let them get near the city walls!"

Xuan Fengzi shouted loudly, his hands quickly forming a seal. A dazzling spiritual light flew out from his palm, transforming into countless light arrows that shot towards the demons in the air.

Not to be outdone, Liu Zhanshu swung his longsword, unleashing a torrent of sword energy that swept across the demonic army ahead. His sword energy was incredibly sharp; wherever it passed, demons fell one after another, turning into black smoke and dissipating.

Behind them, on the defenses of Jinzhou City, other cultivators from the Great Qian Demon Suppression Division and disciples from various sects also launched attacks to slay demons.

Countless spiritual energies and magical artifacts flew about.

Lin An stood at the very front, the Nine Revolutions Demon-Slaying Blade dancing in his hand, its golden light flashing, constantly releasing its devouring power.

With each strike, dozens of demons were swallowed by the golden light and vanished into nothingness. His figure stood like a war god in the center of the battlefield, unstoppable.

At this moment, with the support of the Nine Revolutions Demon Slayer Blade and the Devouring System, Lin An was already able to challenge Nascent Soul experts two levels higher!

However, the number of demons was simply too great. Even though Jinzhou City had gathered all of Daqian's elite forces, it was difficult to completely stop their offensive.

Soon, the demon army approached the city walls, and the cultivators inside the city began to fight back fiercely.

"Young friend Lin, this can't go on!"

As Xuan Fengzi fought, he shouted, "We must find the commander of the demon army, or we simply cannot afford to lose!"

Lin An nodded, his gaze sweeping over the rear of the demon army.

Sure enough, deep within the demon army, he saw a figure dressed in black robes.

The man's aura was extremely powerful; he was clearly the commander of this demonic army.

"I'll go take care of him!"

Lin An said in a deep voice, then his figure flashed and he rushed into the depths of the demon army.

Seeing this, Xuan Fengzi and Liu Zhanshu immediately followed, clearing a path for him. The three of them were like a sharp sword, piercing straight into the heart of the demon army.

The demon army clearly sensed the three's intentions and rushed forward to stop them.

However, Lin An's devouring power was too domineering; wherever the Nine Revolutions Demon-Slaying Blade passed, demons fell one after another.

Xuan Fengzi and Liu Zhanshu also went all out, their spiritual light and sword energy intertwining to clear away the evil spirits in front of them.

Soon, the three of them rushed to the man in black robes.

"I didn't expect you guys to be able to get this far."

The man in black robes raised his head, revealing a pale and sinister face. His eyes gleamed with an eerie light, and he was surrounded by dense black energy, clearly more powerful than the previous Black Fiend.

"Are you the commander of this demonic army?" Lin An asked coldly.

The man in black robes chuckled, his voice hoarse and cold: "Indeed, I am the Lord of the Sixth Demon Palace of the Extraterrestrial Demons—Ghost Soul. You were able to defeat Black Fiend, so you do have some skill. However, today you are destined to die here."

Lin An sneered, meeting the ghost's gaze without fear: "Who lives and who dies is still uncertain!"

Before he finished speaking, Lin An made the first move, and the Nine Revolutions Demon-Slaying Blade transformed into a golden lightning bolt, striking straight at the head of the ghost.

The ghost snorted coldly, its figure flashing like a phantom as it dodged, while simultaneously unleashing a wisp of black energy that hurtled straight towards Lin An.

Lin An swiftly dodged, the black energy grazing past his body and striking a group of demons behind him, instantly devouring them.

"Such powerful corrosive force!"

Lin An was startled and dared not be careless in the slightest.

Xuan Fengzi and Liu Zhanshu also joined the battle, and the three of them worked together to besiege Youhun.

However, the ghost's strength far exceeded their expectations. His figure was as elusive as a phantom, and black energy constantly surged from his body, transforming into countless black tentacles that tried to entangle the three of them.

"Be careful! This black energy has corrosive power. Once you get entangled with it, the consequences will be unimaginable!" Xuan Fengzi warned loudly.

Lin An nodded, and the Nine Revolutions Demon Slayer Blade in his hand shone brightly with golden light, continuously releasing its devouring power to engulf the approaching black energy.

However, the ghost's black aura seemed endless; even after some was devoured, more black aura continued to surge forth.

"This can't go on!" Liu Zhanshu said in a deep voice. "We must find his weakness!"

A resolute glint flashed in Lin An's eyes as he whispered, "Seniors, please hold him off for a moment. I'll give it a try!"
