After more than ten years on the mountain, you will become invincible when you come down.

In the blink of an eye, the two figures met in the air and collided violently.

In an instant, the entire space seemed to be torn apart, causing thousands of huge waves.

Their powers intertwined and collided with each other, forming a huge energy vortex that drew everything around it in.

However, this time, Lu Feng's power was obviously stronger.

Each of Lu Feng's punches contained endless power, forcing the Demon Emperor to retreat step by step.

Although the Demon Emperor tried his best to resist, he was gradually at a disadvantage and could not withstand Lu Feng's fierce attack.

Although Lu Feng had the upper hand, he still frowned slightly.

Because Lu Feng discovered that even if he sealed this world, the Demon Emperor's recovery was still very fast...

I injured the Demon Emperor a second ago, but the other party's wound healed in a short while...

"Master, it's useless. After sealing this world, they resurrected on the spot, even faster than before!" Xiaolong exclaimed.

"Hahaha... Lu Feng, you didn't expect that where there is demonic energy there are demons. Even if you seal this world, you still can't kill us..." The Demon Emperor laughed.

Lu Feng's frown gradually relaxed. The Demon Emperor had revealed his weakness. He probably thought he couldn't handle the demonic energy...

"Haha...it was indeed my negligence, but it doesn't matter. Soon they won't be able to laugh anymore..." Lu Feng sneered.

"Hehe... So what if you are not careless? Can you handle these demonic energy? I forgot to tell you that there will be demonic energy in places where there are many demons. What's more, this is the base camp of our demon clan..." The Demon Emperor sneered disdainfully.

As Lu Feng sneered, the Heaven-Swallowing Gourd appeared in his hand.

"Heaven-Swallowing Gourd, absorb all this evil energy for me!" Lu Feng shouted in a deep voice.

The Heaven-Swallowing Gourd can devour everything, let alone this little bit of evil energy.

The Heaven-Swallowing Gourd grew in the wind, and in the blink of an eye it became as big as a small mountain. A strange light flashed at the mouth of the gourd, generating a suffocatingly strong suction force! This suction force was like a greedy beast, baring its fangs and claws and pouncing around, sucking in the dense demonic energy around it.

The Demon Emperor widened his eyes with an expression of disbelief on his face. He never dreamed that Lu Feng actually possessed such a terrifying magic weapon!

A wave of fear and uneasiness surged in the Demon Emperor's heart, because he knew clearly that the appearance of this magic weapon would bring about earth-shaking changes to the entire battle situation.

As more and more demonic energy was devoured by the Heaven-Swallowing Gourd, the Demon Emperor's source of power was severely weakened.

The Demon Emperor's aura, which was originally as powerful as a demon god descending to the earth, began to waver at this time.

The Demon Emperor's body gradually became weaker, and every movement he made seemed as difficult as if he was being weighed down by a heavy burden.

The body, which had originally recovered quickly, now became slow, and the speed of wound healing slowed down significantly.

"This...how is this possible..." The Demon Emperor looked at the Heaven-Swallowing Gourd in Lu Feng's hand in horror.

"Keep being so arrogant. I wonder who can save you now!" Lu Feng said in a deep voice.

Lu Feng took advantage of the victory and attacked the Demon Emperor again with a flash.

Lu Feng was as fast as lightning and arrived in front of the Demon Emperor in the blink of an eye.

The Human Emperor Sword in his hand flashed with cold light and carried a sharp sword energy as he slashed fiercely at the Demon Emperor.

The Demon Emperor was startled and a magic wand appeared in his hand. He quickly raised the magic wand to resist.

However, Lu Feng's attack came like a violent storm, leaving him overwhelmed.

The Demon Emperor could only keep retreating, trying to avoid Lu Feng's attack.

At this time, the Demon Emperor had long lost his previous majesty. His face turned pale and cold sweat broke out on his forehead.

Under Lu Feng's fierce attack, he could only defend himself and had no power to fight back.

He began to regret underestimating his enemy. He did not expect Lu Feng to be so powerful.

"Lu Feng, let's discuss a ceasefire. How about that? I'll let you leave Lingshan safely..." said the Demon Emperor.

"What the hell are you thinking about? We went to Lingshan to destroy you demons and Buddhism! Are you crazy to negotiate such conditions with me?" Lu Feng sneered.

"Lu Feng, I advise you to think carefully. If you want to kill me, it will probably not benefit anyone!" the Demon Emperor said coldly.

"Don't think about it, just die!" Lu Feng flatly refused.

If they were at a disadvantage at the beginning, Lu Feng might have considered it for everyone's safety.

But now that so many people have been sacrificed, and they are about to be wiped out, how could Lu Feng agree to this...

Lu Feng did not give the Demon Emperor any chance to breathe, he continued to launch a fierce attack.

Lu Feng's swordsmanship became more and more sharp, and each sword contained endless power.

There were already many wounds on the Demon Emperor's body, and blood had stained his black robe red.

The Demon Emperor knew that if he continued like this, he would most likely be defeated by Lu Feng.

So he decided to use his last trick.

"Since you don't want to negotiate, don't blame me for being rude!" the Demon Emperor said coldly.

The Demon Emperor took a deep breath, gathered all the magic power in his body, and then injected it into the magic wand.

Suddenly, the magic wand emitted a dazzling light, and a powerful energy wave emanated from it.

The Demon Emperor waved his wand and chanted a spell.

A black flame gushed out from the magic wand and swept towards Lu Feng.

The flame was so powerful that space was distorted wherever it passed.

Seeing this, Lu Feng did not dare to be careless.

Lu Feng quickly used his skills to dodge the black flame sideways.

At the same time, Lu Feng swung his sword again and launched a new round of attack towards the Demon Emperor.

There was a determined light in Lu Feng's eyes, he knew very well that he could not let the Demon Emperor succeed.

Lu Feng concentrated his energy, mobilized the Hongmeng purple energy in his body, and went all out to meet the attack of the Demon Emperor.

Lu Feng's figure was like a ghost, moving through the black flames at an astonishing speed, as if he was in control of the entire space.

The sword in Lu Feng's hand danced more and more fiercely. Every time the sword was swung, it carried a powerful sword energy. The sword shadows intertwined into an impenetrable net, tightly enveloping the Demon Emperor.

The Demon Emperor was secretly shocked. He didn't expect Lu Feng to be so powerful and could easily avoid his special moves.

But the Demon Emperor was not willing to be outdone. He continued to mobilize the magic power in his wand, trying to break through Lu Feng's defense.

However, Lu Feng's strength far exceeded his expectations.

Lu Feng's sword light was as fierce as thunder. Each sword contained endless power, which instantly forced the Demon Emperor back several steps.

The Demon Emperor sighed inwardly, knowing that he could no longer defeat Lu Feng today. Although he was unwilling to accept it, he could only admit this fact.

The Demon Emperor looked at Lu Feng with gritted teeth, then looked at the corpses of demons scattered all over the ground, only then he realized that there were only a few demons still alive, and there was almost no demonic energy in this world. The few remaining ones were simply unable to support his resurrection, and were all sucked away by the Heaven-Swallowing Gourd.
