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

"No, I... I cannot lose! I am the supreme Demon Emperor!" Mo Yuan roared, then suddenly clasped his hands together, and the demonic energy in his body boiled to the extreme, as if he wanted to burn himself out in exchange for the strength of one last fight. "Heart of the Demon Realm, resonate with me, devour all things, and reshape the universe!"

"This is the Heart of the Demon Realm! No... no, Lord Demon Emperor, please stop!" The Demon Realm masters cried out in horror upon seeing this. They knew that the Heart of the Demon Realm was the most powerful source of power in the Demon Realm. If the Demon Emperor forcibly resonated with it, not only would their magic power be drained, but the entire Demon Realm would also face a devastating disaster.

However, Mo Yuan was almost crazy at this moment. All he saw was revenge and victory, and he didn't care about the consequences at all.

When Tian Yunzi saw this, his face changed. He knew very well the power of the Heart of the Demon Realm. If it got out of control, the consequences would be unimaginable.

"Moyuan, are you crazy? If you do this, you will not only destroy yourself, but also affect the entire Demon Realm and even the balance of the outside world!" Tian Yunzi shouted angrily, with unprecedented seriousness and urgency in his voice.

"Hahahahaha... Tianyunzi, are you scared? I never thought that the almighty Great Elder of the Divine Profound Palace would panic like this. But today, I have no way out. I would rather perish with you than let myself be destroyed!"

Mo Yuan's laughter echoed through the air, carrying a note of sadness and resoluteness. His demonic energy resonated with the Heart of the Demon Realm, and the entire Demon Realm began to shake violently, as if a giant beast was about to awaken from the earth. Thick black clouds obscured the sky, obscuring all sunlight.

"Master, we must stop this madman, otherwise the entire Demon Realm will be destroyed!" Seeing this, Nuo Yao looked at Lin Han anxiously, her voice trembling.

"Don't worry, I have my own plans." Lin Han responded softly, and then his figure flashed, and he rushed directly towards the Demon Abyss that was madly absorbing the heart of the Demon Realm.

"What are you doing here, you little bastard? Run away quickly, the farther the better!" Tian Yunzi's face suddenly changed when he saw this. He didn't expect Lin Han to rush forward so impulsively.

"Old drunkard, this is a bit unkind of you. I am your apprentice. How can it be that the master fights hard in the front while the apprentice runs away from the battlefield?" Lin Han raised the corner of his mouth with a playful smile, his eyes flashing with determination and fearlessness.

"Hahahaha... Inspector Lin, you could have escaped, but you chose to come here and die. How foolish!" Mo Yuan laughed wildly upon seeing this, his eyes flashing with cruelty. In his view, Lin Han's actions were tantamount to walking into a trap, and he could just get rid of this annoying guy at the same time.

"Haha... Escape? You're overthinking it, you piece of shit! You're a piece of shit, and you're not even close to being able to let me escape." Lin Han sneered, "It would be easy for me to kill you. No matter how you fuse with this Demonic Heart, you'll only be able to survive."

"Haha... Inspector Lin is quite arrogant, but today, I will let you see what true despair is!" Mo Yuan's laughter was mixed with madness. The demonic energy in his body resonated with the heart of the Demon Realm to the extreme. The sky of the entire Demon Realm seemed to be torn apart, and endless darkness and the breath of destruction came overwhelmingly, enveloping Lin Han and Tian Yunzi.

"You little bastard, run away now that you're done pretending. I'll delay him and buy you some time to escape. Remember to bring those twenty bottles of Wuliangye to my grave by this time next year!" Tian Yunzi said anxiously, his spiritual power surging. He knew very well that it would be difficult to completely stop the Demon Abyss with his own strength, but at least he could buy Lin Han a glimmer of hope.

"Haha... escape? It's too late!" Mo Yuan's laughter echoed between heaven and earth, carrying with it an unquestionable majesty and madness.

"Old drunkard, just wait and see how I beat this loser until he doubts his life!" Lin Han gave Tian Yunzi a confident smile.

"The power of heavenly punishment - activate," he muttered in his heart, and then the [Heavenly Punishment Ring] on his finger flashed, and an ancient and vast aura suddenly burst out from Lin Han's body. It was a power that transcended the mortal world and touched the laws of heaven and earth.

The sky seemed to be torn apart by an invisible giant hand, and an unprecedented pressure descended from the sky. It was the purest force of punishment between heaven and earth - heavenly punishment.

"Heavenly punishment - thunderous!" Lin Han's voice was particularly clear in the thunder. As his words fell, the originally thick black clouds in the sky were torn apart in an instant, and thick lightning pillars descended from nothingness, like the wrath of the gods, striking directly at the Demon Abyss.

Mo Yuan's expression became extremely solemn at this moment. He could sense the destructive power contained in this force, far beyond his imagination. He desperately mobilized the power of the Demonic Heart, trying to resist the punishment of this heavenly punishment, but the power was too great, as if it could annihilate everything.

"No - this is impossible!" Mo Yuan roared, his body trembling under the bombardment of thunder and lightning, and the resonance between the demonic energy and the heart of the demonic realm began to become disordered. The power that tried to devour everything seemed so small under the punishment of heaven.

Lin Han stood in mid-air, surrounded by a faint flash of lightning, which was the lingering power of heavenly punishment. His eyes were cold and firm, as if he could see through all the vanity in the world.

Under the divine punishment, Mo Yuan's struggle seemed so powerless, his demonic energy was torn apart by pillars of lightning, and the resonance of the Heart of the Demon Realm gradually weakened.

"Rubbish, what do you think? Do you know what despair is now?" Lin Han's voice echoed amidst the thunder, carrying an undeniable majesty. He flicked his finger, and the lightning pillars in the sky became more dense, each one containing enough power to destroy mountains and rivers, heading straight for the Demonic Abyss.

"No... I won't accept this! I am the Demon Emperor, how can I be defeated by a junior like you!" Mo Yuan roared, his voice full of anger and unwillingness, but the demonic energy in his body was almost exhausted, and the resonance of the Heart of the Demon Realm was gradually dissipating, and it could no longer support him to fight back.

Lin Han watched Mo Yuan's struggle coldly, without any ripples in his heart.

"Everything in the world has its destiny. You used the Heart of the Demon Realm as bait, trying to subvert the world, but you forgot that the law of nature is cyclical and retribution will come." Lin Han's voice was calm and powerful, penetrating the thunder and striking deep into the soul of Mo Yuan.

"Although I am an inspector, I protect not only order but every living being on this continent. Your ambition and cruelty have already doomed you to this day."

"I... I lost..." Mo Yuan's voice was weak and trembling. This was the first time in his life that he admitted defeat, and it would also be the last time.

As Mo Yuan finished his words, the demonic energy surrounding him quickly dissipated like air being sucked away. The Heart of the Demon Realm, which once made the entire Demon Realm tremble, also lost its light and slowly sank into the ground, as if it had never existed.
