Devouring demons, I attain immortality.

Just then, Lin An suddenly thought of a solution.

He quickly turned to Xuan Fengzi and Liu Zhanshu and said, "Seniors, you two hold off the demon army's attack first. I'll go find reinforcements!"

Xuan Fengzi and Liu Zhanshu were both stunned; they hadn't expected Lin An to have such a thought.

But there was no time to hesitate, so they could only nod in agreement.

"Alright! Go ahead! We'll try our best to hold them off!" Xuan Fengzi said in a deep voice.

Lin An nodded, then his figure flashed and flew away into the distance.

He was going to find those powerful individuals hidden in the shadows, so that they could join forces to resist the invasion of the demon army.

When Lin An first arrived in Jinzhou City, the Devouring System sensed some special presences.

However, since these reclusive masters were unwilling to come out of seclusion, Lin An had no intention of disturbing them, but now he had no choice but to ask them to come out of seclusion.

After flying for several hours, Lin An finally found a hidden cave.

The cave is filled with spiritual energy, like a blessed land.

He entered the cave and found several incredibly powerful cultivators practicing inside.

"Esteemed seniors, my name is Lin An, and I have an important matter to ask of you!" Lin An said respectfully.

Upon hearing this, the cultivators opened their eyes, and instantly the entire cave was filled with golden light.

Behind each of these cultivators, a massive golden projection unfolded.

This is... the Void Reset Realm?

Since Lin An transmigrated to another world and obtained the Devouring System, he has gradually learned about the information of this world.

Especially in the cultivation system, above the Nascent Soul Realm, there are also Returning to Emptiness, Astral Projection, Dividing the Spirit, Merging the Body, Penetrating Emptiness, and Merging with the Dao.

The difference between returning to the void and transforming into a spirit may seem like just one step, but it is as different as heaven and earth.

Unexpectedly, these cultivators all possessed the Void Returning Realm.

The few cultivators at the Void Returning Realm looked at Lin An with cold eyes, a hint of doubt flashing in their eyes.

"This is the Golden Light Cave. I am Huang Tian Zhenren. Who are you? What do you want from me?" one of the cultivators asked.

Lin An quickly recounted the invasion of the Great Qian by extraterrestrial demons and asked them for help.

Upon hearing this, the cultivators' expressions all turned solemn.

"The extraterrestrial demons are so rampant!" Huang Tian Zhenren roared. "How can we, as cultivators, sit idly by and do nothing?"

"Excellent!" another cultivator nodded in agreement. "Young friend Lin An, don't worry! We'll go back with you now and fight together against the demonic army!"

"Seniors, I still have a question. Since you are already super strong experts in the Void Returning Realm, with your divine sense covering the heavens and earth, why do you turn a blind eye to what is happening in the outside world?"

Lin An suddenly realized that with the strength of cultivators like Huang Tianzhen, it was impossible for them not to notice what was happening in Jinzhou City.

"Young friend Lin, you may not know this, but we sealed our divine senses and went into seclusion in this Golden Light Cave three hundred years ago. If you hadn't broken into the Golden Light Cave, we might not have come out of seclusion even after another three hundred years..." another True Person said calmly.

Lin An nodded, acknowledging that it was indeed presumptuous of him.

"Seniors, I have offended you!" Lin An said, bowing.

"It's alright. Since you've come, it must be fate. We'll go with you and see just how arrogant these extraterrestrial demons are," another True Man draped in python skin said slowly.

Lin An was overjoyed upon hearing this and quickly expressed his gratitude. If these experts at the Void Returning Realm could help, then the crisis in Jinzhou City could be resolved.

When they returned to Golden State, they found that the demon army's offensive had become even more intense.

Although Xuan Fengzi, Liu Zhanshu, and the others had given their all, they were gradually starting to feel the strain.

The weaker cultivators perished one after another.

"Young friend Lin An, you're finally back!"

Xuan Fengzi breathed a sigh of relief when he saw Lin An return with several True Immortals.

Xuan Fengzi's eyesight was incredibly sharp; she could see the extraordinary nature of these masters at a glance.

"Gentlemen, I am Xuanfeng, and I pay my respects!" Xuanfengzi bowed deeply.

The individuals nodded in response.

Lin An nodded and quickly introduced the several True Immortals to Xuan Fengzi and Liu Zhanshu. Then, they joined the battle together.

With the addition of those real people, the defenses of Jinzhou City became much stronger.

The few True Immortals at the Void Returning Realm all took action to fight against the invading Demon Palace members.

Gradually, the extraterrestrial demons began to decline.

Lin An was overjoyed upon seeing this.

He knew that if he persisted a little longer, he might be able to completely defeat the demon army.

However, at that moment, a deafening roar suddenly came from the sky.

Lin An looked up and saw a huge demon hovering in the sky. Its body was as big as a mountain and it was surrounded by thick black energy.

"That's... the Demon Lord of the extraterrestrial demons!" Xuan Fengzi's expression changed drastically, and he whispered.

Lin An was also stunned. He hadn't expected that the extraterrestrial demons would send out such a powerful being.

He knew that this demon lord was far more powerful than the previous ghosts and black demons, and they would probably have no chance of resisting him.

Those few real people were also entangled in the demon palace of the extraterrestrial demons and could not spare any hands to help.

"What should we do?" Liu Zhanshu asked anxiously.

Lin An gritted his teeth and said in a deep voice, "No matter what, we cannot let it get close to the city walls! Otherwise, Jinzhou City will be finished!"

Before he finished speaking, Lin An rushed out first.

The Nine-Turn Demon-Slaying Blade in his hand shone brightly with golden light, its devouring power surging wildly. He charged towards the demon, attempting to stop it outside the city wall.

However, the Demon Lord seemed to have seen through Lin An's intentions. It let out a deafening roar and slammed its enormous claws down towards Lin An.

Lin An hurriedly swung his sword to defend himself, but the force made him feel a chill run down his spine.

"So strong!"

Lin An was secretly alarmed. He knew he was no match for the Demon Lord. But even so, he could not back down.

Just then, Xuan Fengzi, Liu Zhanshu, and the others arrived. They all took action, trying to help Lin An withstand the demon lord's attack.

However, the Demon Lord's power was simply too great, and their attacks could not cause any real damage to it.

"This can't go on!" Lin An was extremely anxious.

He knew that if things continued like this, they would be defeated by this demon lord sooner or later.

Just then, he suddenly thought of the Devouring System. He quickly called upon the system in his mind, asking if there was a way to defeat this Demon Lord.

[Ding! The system has detected that the host is facing a life-or-death crisis. Do you want to activate the 'Ultimate Devouring Technique' function of the 'Devouring System'?] The system's voice rang in Lin An's mind.

"Ultimate Devouring Technique?"

Lin An was taken aback, then his heart leaped with joy. He quickly asked, "How many resources are needed to activate this feature?"

[Ding! Activating the 'Ultimate Devouring Technique' function requires 10000 taels of gold and will place a great burden on the host's body. Confirm activation?] The system replied.

Lin An gritted his teeth and said in a deep voice, "Confirm activation!"

[Ding! The 'Ultimate Devouring Technique' function has been activated, consuming 10000 taels of gold. Host, please prepare for a tough battle ahead.]

As the system notification ended, Lin An felt an unprecedented power surge from within his body.

His body seemed to be enveloped in a golden light, and the golden light on the Nine Revolutions Demon Slayer Blade became even more dazzling.

"Break!" Lin An shouted, and suddenly swung his sword. Golden light surged out like a tide, heading straight for the demon.

The Demon Lord clearly noticed Lin An's change; its expression changed drastically, and it tried to hide.

However, that golden power followed it like a shadow, clinging tightly to it.

"No! This is impossible!" the Demon Lord roared in terror.

However, no matter how hard it struggled, it could not withstand Lin An's attack.

Golden light surged toward the Demon Lord like a tide, surrounding him completely.

The demon's body began to tremble, as if bound by an invisible force.

"Devouring power, devour!"

Lin An let out a low shout, and the devouring power within his body surged wildly.

The golden light swirled like a vortex, gradually engulfing the Demon Lord's body.

The Demon Lord let out a painful roar, but its power was rapidly draining away.

Soon, its body was completely engulfed by the golden light, turning into a wisp of black smoke and disappearing without a trace.

With the death of the Demon Lord, the demon army immediately fell into chaos.

They began to scatter and try to escape Golden State City.

However, Lin An and his group did not let them go.

Several newly emerged cultivators took action, unleashing various magical treasures and spiritual power to annihilate the demon army one by one.

The battle lasted for several days before finally coming to a complete end.
