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

As soon as these words were spoken, the atmosphere within the cage suddenly became tense. Fengyou Demon Lord and Nuoyao's mother looked at each other, their eyes filled with disbelief and confusion.

"Inspector Lin, what do you mean? Although I was once the lord of the Demon Realm, since I was betrayed and imprisoned by Mo Yuan, the Demon Realm has fallen into his hands, and I have long lost control of the Demon Realm." There was a bit of bitterness and helplessness in the voice of Demon Lord Feng You. Obviously, he had a clear understanding of the current situation.

"Nuoyao, you go and tell your father." Lin Han smiled slightly and turned the topic to Nuoyao.

Nuoyao nodded after hearing this. After a moment's silence, she said, "Father, my second uncle is already...dead!"

As soon as these words were spoken, it was like thunderclap out of the blue, leaving Fengyou Demon Lord and Nuoyao's mother stunned for a moment, with shock and disbelief in their eyes.

"Yao'er, you mean... Moyuan..." The voice of Demon Lord Fengyou was trembling. He tried hard to calm the waves in his heart and tried to get more information from his daughter.

"That's right, father. Just now outside, Second Uncle was dueling with Senior Tian Yunzi and didn't want to admit defeat, so he forcibly activated the Heart of the Demon Realm to gain powerful strength. In order to protect the entire Demon Realm from destruction, Master had no choice but to stop him, so..." At this point, Nuo Yao's voice paused slightly, and a complex emotion flashed in her eyes. There was both helplessness towards Second Uncle Mo Yuan's actions and understanding and gratitude for Lin Han's intervention. "Second Uncle, under the backlash of the Heart of the Demon Realm, was ultimately destroyed."

"Mo Yuan... he's ultimately embarked on this path of no return." Demon Lord Feng You's voice was low and heavy, tinged with an indescribable sorrow. He opened his eyes, his gaze now firm. "Yao'er, you're right. If Mo Yuan's ambitions aren't curbed, the entire Demon Realm will be doomed. Inspector Lin, thank you for your help. You not only saved my daughter, but also averted a catastrophe for the Demon Realm."

Lin Han couldn't help but shake his head and sighed, "Lord Wind Demon, you're too serious. As an inspector of the Divine Mysterious Palace, it's my duty to maintain the balance of the world. What happened to the Demon Abyss was simply in accordance with fate. If he had had good intentions, perhaps there would have been a different outcome."

Tian Yunzi nodded silently, a trace of vicissitudes and emotion flashing in his eyes: "Everything in the world has its cause and effect. The fall of Mo Yuan may be the result of his own choices."

"Father, my second uncle realized his mistake in his final moments. He asked me to say, 'I'm sorry!'" Nuoyao's voice was tinged with sorrow, yet also revealed a sense of relief. She knew that while blood was thicker than water, there was ultimately an unbridgeable chasm between justice and evil.

Upon hearing this, the Demon Lord Fengyou trembled slightly. After a moment of silence, he slowly spoke, "Forget it, forget it. Although he is my biological brother, he has chosen a path that opposes me. I receive this apology, and I hope he can find true peace in another world."

Heiyan stood aside, his eyes complex, a mixture of regret for Moyuan's passing and joy for Fengyou Demon Lord's regaining his freedom. He knew that as Fengyou Demon Lord's loyal subordinate, he still had a long way to go and needed to continue to protect this land.

"Master, what should we do next?" Heiyan asked, his voice full of anticipation and determination.

Demon Lord Fengyou looked at Lin Han, his eyes gleaming with inquiry. He knew that Lin Han was not only Nuoyao's master, but also a powerful being with extraordinary abilities. His opinion was crucial.

Lin Han pondered for a moment, his gaze sweeping across everyone present, finally landing on Fengyou Demon Lord. "Fengyou Demon Lord, you were once the Lord of the Demon Realm, and you know everything here like the back of your hand. Now that Demon Abyss is gone, the Demon Realm is in a state of disarray. This is the perfect time for you to revive your cause and lead the Demon Realm into a new era."

"But..." Fengyou Demon Lord looked troubled. "Although I have the intention, I have been imprisoned for many years and my strength is not as good as before. How can I convince others?"

"Strength can be restored, and prestige can be rebuilt." Lin Han said firmly, "Besides, you have capable assistants like Nuoyao and Heiyan, and the backing of the Shenxuan Palace. As long as you uphold justice and put the people first, I believe the creatures of the Demon Realm will once again support you."

Tian Yunzi also spoke at the right time: "Fengyou Demon Lord, I am willing to lend you a helping hand. Although the Shenxuan Palace and the Demon Realm belong to different realms, maintaining world peace and stability is our common goal."

Upon hearing this, Demon Lord Feng You felt a surge of warmth in his heart. He knew that at this moment, he wasn't just doing this for himself, but for the future of the entire Demon Realm. He took a deep breath, his eyes gleaming with determination. "Okay! I, Feng You, am willing to take on this important responsibility and lead the Demon Realm into a new chapter!"

With the firm promise of Demon Lord Fengyou, the atmosphere in the cage instantly became solemn and full of hope.

Nuoyao and her mother smiled at each other, their eyes full of relief and pride. They knew that their father had finally found his kingly spirit again.

Seeing this, Lin Han nodded secretly in his heart. He believed that Demon Lord Fengyou could lead the Demon Realm into a new era.

"Demon Lord Fengyou, may I have a word with you?" Lin Han suddenly spoke, with a seriousness in his voice that could not be ignored.

Demon Lord Feng You was stunned for a moment, then nodded, motioned everyone to wait, and walked to a more secluded corner with Lin Han.

"Inspector Lin, is there anything important that we need to discuss in private?" Demon Lord Feng You looked directly at Lin Han with a sharp gaze, waiting for his next words.

Lin Han's eyes were deep. After a moment's silence, he slowly said, "Lord Wind Demon, do you know anything about the Heavenly Demon King?"

"The Sky Demon King?" Upon hearing this, the Wind Demon Lord frowned, a look of solemnity flashing in his eyes. "To be honest with Inspector Lin, the Sky Demon King is sealed within the forbidden grounds of the Tenth Layer Demon Realm. The Sky Demon King is one of the most powerful demons of ancient times, powerful enough to overturn the entire Demon Realm and even the wider world. If it truly breaks free, the consequences will be disastrous."

"The Tenth Devil Realm?" Lin Han's eyes lit up. "Lord Wind Demon, where is it located?"

"Inspector Lin, even I'm not entirely sure of the exact location of the Tenth Layer Demon Realm. It's so deeply hidden that even when I was the Lord of the Demon Realm, I couldn't fully explore its location. It's said that countless ancient magic formations and restrictions have been laid there, making it difficult for even me, at my peak, to easily set foot there."

"Oh? So that's how it is. The threat posed by the Demon King is far more troublesome than I thought." Lin Han frowned, his eyes flashing with solemnity.

"Thank you, Lord Wind Demon, for telling me!" Lin Han continued, bowing slightly to express his gratitude.

The Wind Demon Lord waved his hand and said, "Inspector Lin, you're welcome. The affairs of the Demon Realm are my responsibility. If that day ever comes, I, Feng You, will be duty-bound to fight alongside you against the Demon King and protect the peace of this land."
