Starting with the Immortal Cultivation System, what can you use to fight me?

Immediately afterwards, Mo Shan flew backwards and fell heavily to the ground, creating a hole that was even bigger than the one created by Mo Tian before.

"What?! Lord Mountain was defeated too?"

"Oh my god, what kind of monster is this human youth? Even Lord Moshan is no match for him?"

The surrounding demon soldiers and masters exclaimed again, and their eyes were full of fear and awe when they looked at Lin Han.

At this moment, in their eyes, Lin Han was no longer an ordinary human youth, but a powerful monster!

"Oh, how boring." Lin Han shook his head, a look of disappointment on his face. "I thought this guy called Demon Mountain would bring me some challenges, but I didn't expect him to be so vulnerable."

He said this, and his eyes swept over the surrounding demon masters again, "Are there any of you who want to come up and die? Come on, I will stand here today and let you demon masters challenge me to your heart's content!"

"Damn, even Uncle Moshan is no match for him!" Ao Yunfeng's face was extremely ugly at this moment. He thought that he could take down Lin Han with the help of the masters of the Demon Realm today, but he didn't expect the result to be like this.

"Young man, you are indeed very strong, but do you think you are invincible?" A deep voice suddenly sounded, silencing all the noise.

Lin Han raised his eyebrows and looked in the direction of the voice. He saw an old man in a black robe with a sinister face walking down from the sky not far away. He exuded a heart-pounding aura of oppression. It was obvious that he was a master with unfathomable strength.

"Great! The Demonic Elder has arrived!"

"The Great Elder is a being that can rival the Demon Emperor. If he takes action, this kid will be killed!"

The surrounding demon soldiers and masters all showed awe and admiration when they saw the black-robed old man. They knew that this old man was called Mo Kuang, a great elder in the Demon Realm, second only to the Demon Emperor in strength, and a true top master.

The demon madman slowly landed in front of Lin Han, staring at him with a pair of sinister eyes, as if he wanted to see through his soul.

"Young man, your strength is beyond my expectation, but you should never come to our Demon Realm to run wild." The demon said coldly, "Today, let me meet you and see how powerful you are!"

"Alas... I am no longer capable. Now here comes another old guy. Your Demon Realm is really interesting." Lin Han shook his head slightly, with a playful smile on his lips.

"You are such a sharp-tongued boy! I hope your words can be as tough as your strength." The demon madman's voice was low and powerful. Before he finished speaking, a strong demonic aura had spread around him, as if even the air around him was distorted by this power.

"Come on, let me see how powerful the Great Elder of the Demon Realm is." Lin Han's voice was calm and firm, without any fear.

Seeing this, the devil curled up a sneer at the corner of his mouth, and his figure instantly disappeared from the spot, leaving only a residual shadow.

"Mr. Lin, now that the Great Elder has taken action, you are doomed to die! Haha..." Ao Yunfeng sneered secretly.

"This human kid was able to force the Great Elder to show up. This kid's death was deserved." The surrounding demon masters also echoed. They knew that once the Demonic Madness Great Elder took action, almost no one could escape his clutches.

However, facing the demon's ghostly speed and powerful demonic pressure, Lin Han did not show any panic.

"Nine Heavens Divine Thunder Fist—"

Lin Han said in a low voice with a calm face, and then the demonic realm, which was originally covered with layers of black air, suddenly changed, with dark clouds and roaring thunder, as if the sky was torn apart.

“This… this is…” The pupils of the Demon Madman and all the demons present suddenly shrank, and they were too shocked to speak.

"Click——!"

Before they could react, a thick purple divine lightning streaked across the sky and crashed down from the depths of the dark clouds. Wherever the lightning passed, those weak demon soldiers were instantly turned into ashes, without even being able to utter a scream.

Ao Yunfeng and other demon masters hurriedly used all their skills to try their best to resist this destructive force, but their body-protecting magic energy was so fragile under the divine thunder that they were knocked back one after another. Some even vomited blood and their faces were as pale as paper.

The Demon Madman was also in a tough spot. Although he was the Great Elder of the Demon Realm and his cultivation was unfathomable, he was forced to give it his all in the face of this sudden Nine Heavens Divine Thunder. His black robe fluttered, and demonic energy surged wildly around him, transforming into a pitch-black shield, attempting to withstand this earth-shattering thunder.

"Rumble--"

The divine thunder collided with the shield, unleashing a deafening roar and a dazzling light, as if the entire world were trembling. The demonic madman's body shook violently, and he involuntarily stumbled back several steps, his expression grave. He had never imagined that this seemingly ordinary human youth could possess such terrifying thunder-related magical powers.

"You... who are you? When did a monster like you appear among the human race!" The demon madman's voice was filled with disbelief and shock. He knew very well that if he could not get rid of this person today, it would be a huge threat to the Demon Realm.

"Oh... I didn't expect that you, an old man, could still withstand my attack. That's quite interesting." Lin Han raised the corner of his mouth with a faint smile.

"The Demonic Elder, his name is Lin Feiyu!" Ao Yunfeng said gritting his teeth.

"Lin Feiyu?" The devil repeated the name, a thoughtful look in his eyes.

"I don't remember anyone named Lin Feiyu among the young and powerful human beings..."

"Wait...Lin Feiyu!"

The demon madman seemed to remember something, and then his eyes widened, a glint of disbelief flashing in his pupils. "Could it be... you are the newly promoted Forest Patrol Officer of the Divine Mysterious Palace who has recently become famous among the human race!?"

As soon as these words were spoken, an uproar erupted. Even the demon experts, who prided themselves on their extensive knowledge, expressed shock. The Divine Mysterious Palace was the most powerful force in the human race, and its inspectors were endowed with supreme honor and power. Each one was a leader among the human race, possessing exceptional strength.

"Hey... old thing, I didn't expect you to be so knowledgeable. You've even heard of my name." Lin Han's mouth curled up slightly, with a hint of teasing in his tone, but his deep eyes flashed with a sharpness that should not be underestimated.

"However, I am not here today to show off my status, but to collect a debt from you demons for my subordinates!"

"Collecting a debt? What debt?" asked the crazy demon, somewhat puzzled.

"Uncle Mo Kuang, are you really so old and blind that you can't even recognize me?" Nuo Yao took a step forward, her voice crisp and firm, with a hint of unquestionable majesty.
