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

Then his body softened and fell heavily to the ground. The Demon Emperor's majesty and power disappeared at this moment, leaving only a scarred and dying body.

"Mo Yuan, what you lost is not only strength, but also the paranoia and greed in your heart. Remember, true strength does not lie in how much you can conquer, but in how much you can protect." Lin Han slowly landed beside Mo Yuan and said word by word.

"Hahaha... I, Mo Yuan, have been undefeated throughout my life, but in the end, I fell into the hands of a young boy like you. But, you are right, I was too greedy, too obsessed with power and revenge, and ignored the meaning of protection. I am convinced of today's defeat." There was a bit more relief in Mo Yuan's laughter, but more of it was regret for the past.

Then, he turned his gaze to Nuoyao: "Niece Nuoyao, I'm sorry! Uncle killed you and your elder brother and sister-in-law for power... This is the biggest mistake I have made in my life. If there is an afterlife, I will repay you with my life. I only ask that you can forgive my sins today." Mo Yuan's gaze suddenly turned to Nuoyao not far away, his eyes full of complex emotions, including regret, reluctance, and a hint of relief.

"If I had known this would happen, why did I do it in the first place? Uncle..." Nuoyao said indifferently. But a subtle tenderness flashed in her eyes.

"Niece Nuoyao, this is the key to the Nine-Layered Demon Realm prison. My elder brother and sister-in-law are inside. Tell them, 'I'm sorry!'" Mo Yuan then struggled to pull a shimmering ancient key from his bosom and, with his last remaining strength, tossed it toward Nuoyao. The key traced a brilliant arc through the air before landing firmly in her palm.

Nuoyao took the key and gently stroked the cold surface with her fingers, feeling mixed emotions.

She looked at Mo Yuan's gradually dimming eyes, and an indescribable emotion surged in her heart. The hatred and anger she had felt before seemed to be replaced by a more complex emotion at this moment.

"Uncle, I'll tell them." Nuoyao's voice was soft but resolute. She knew that no matter what happened in the past, the man before her was still her blood relative, a bond that no amount of hatred could completely erase.

"All people in the Demon Realm, listen up. From now on, my eldest brother and his family will take charge of the Demon Realm again. You are not allowed to have any objections. You must assist them wholeheartedly and build a new order for the Demon Realm together." Although Mo Yuan's voice was extremely weak, it still carried unquestionable majesty.

Upon hearing this, the masters of the Demon Realm knelt on the ground and responded respectfully: "Yes, Lord Demon Emperor!" Although they were puzzled and shocked by this sudden change, they dared not disobey the Demon Emperor's will.

Afterwards, Mo Yuan's eyes slowly closed, the fire of life was completely extinguished, and a generation of Demon Emperor fell.

Tian Yunzi looked at Mo Yuan's corpse and shook his head. He then looked at Lin Han curiously and asked, "Little bastard, when did you become so strong? The power you displayed just now was so frightening even to me. The power of heavenly punishment is a legendary existence. How did you master it?"

"Guess..." Lin Han raised a mysterious smile.

Tian Yunzi smiled bitterly and shook his head when he heard this. "You are always so secretive, little bastard. Since you are not comfortable revealing anything, I won't ask any more questions."

Next, isn't it time to cash in your 'Wuliangye', hehe..."

"Old drunkard, yours is indispensable." Lin Han smiled faintly, then waved his hand, and a whole box of twenty bottles of "Wuliangye" appeared out of thin air in front of Tian Yunzi. The familiar mellow fragrance instantly spread, making Tian Yunzi's eyes brighten, and the wrinkles on his face seemed to stretch out.

"Haha, you still understand me!" Tian Yunzi laughed, then waved his hand and put it into the storage ring.

"Let's go, Nuoyao, go to the Nine-Layered Demon Realm and rescue your parents!" Lin Han turned and said to Nuoyao, with a warm light in his eyes.

"Well... Master." Nuoyao nodded, her eyes slightly red, but her eyes were full of determination and gratitude.

"Princess Nuoyao, let me lead the way. The Nine-Layered Demon Realm is complex and intricate. I'm familiar with the terrain, which will save us a lot of time." A deep, powerful voice suddenly rang out, interrupting the conversation between the two. Everyone looked in the direction of the voice and saw a middle-aged man in black armor and a stern face standing not far away. It was Hei Yan, a loyal general of the Demon Realm.

Heiyan was once a capable general under Nuoyao's father and was loyal to Nuoyao's family.

"You...you are Brother Heiyan?" When Nuoyao saw Heiyan, a hint of surprise and joy flashed in her eyes, and her voice trembled slightly.

"Your Highness, it's me." Heiyan knelt on one knee, his eyes filled with respect and loyalty. "I knew that Your Highness was a lucky person, and that nothing bad had happened to her as they had rumored."

"Brother Heiyan, don't be like this, get up quickly." Nuoyao hurried forward and wanted to help Heiyan up, but Heiyan insisted on performing the salute before slowly standing up.

"There is no time to lose, Your Highness, we must set off immediately for the Nine-Layered Demon Realm to rescue the master and mistress!" Heiyan stood up, his voice steady and powerful, revealing an unquestionable determination.

"Well... thank you for your help, Brother Heiyan!" Nuoyao said with a smile.

"Your Highness, it's not a problem. This is what we should do." Heiyan waved his hand, turned around immediately, and walked ahead with big strides. Knowing the terrain of the Demon Realm like the back of his hand, he quickly chose the fastest and most hidden path.

Lin Han, Nuo Yao and Tian Yunzi followed closely behind. The figures of the group quickly shuttled through the night, as silent as ghosts.

As we go deeper into the heart of the Demon Realm, the demonic energy around us becomes thicker and thicker. Occasionally, we can hear low roars coming from afar, which are the roars of demon beasts at night.

But Heiyan seemed to be accustomed to this. He held a spear surrounded by black light and looked around vigilantly to ensure the safety of the team.

Finally, before a valley shrouded in thick demonic fog, Heiyan stopped and said in a deep voice, "Your Highness, this is the only entrance to the Ninefold Demon Realm. It's protected by a powerful barrier, making it difficult for ordinary people to pass through. But with the key in your hand, it should be able to be opened smoothly."

Upon hearing this, Nuoyao gripped the key tightly, a mixture of anticipation and nervousness building within her. She took a deep breath, slowly approached the barrier, and aligned the key with the groove in its center. With a gentle humming sound, complex runes began to appear on the barrier, radiating light before finally shattering, revealing a passage leading deeper into the depths.

"Let's go," Lin Han said softly, stepping into the passage first. Nuo Yao followed closely behind, a determined glint in her eyes. Tian Yunzi and Hei Yan followed without hesitation, and the group walked deeper and deeper into the deep passage.
