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

At this moment, Lu Feng suddenly discovered a flaw in the Demon Emperor. He was delighted and shouted without hesitation, "Break!"

Then he swung the sword with all his strength.

This sword was as powerful as a rainbow, like a dazzling rainbow piercing the sun, carrying endless power and heading straight for the Demon Emperor's vital points.

The Demon Emperor's face changed and he quickly dodged to the side, but was still cut by the sharp sword energy.

Lu Feng took the opportunity to launch an offensive, not giving the Demon Emperor any chance to breathe.

His swordsmanship became more and more fierce, pouring down like a torrential rain, making the Demon Emperor exhausted from dealing with it.

The Demon Emperor barely managed to fend off Lu Feng's attack. He had more and more wounds on his body, and blood dyed his black robe red.

He gradually felt that his strength was slipping away and he could no longer hold on.

Finally, Lu Feng used a special move, his sword move was as powerful as thunder, and hit the Demon Emperor hard.

The Demon Emperor screamed, fell to the ground, unable to move anymore.

As the Demon Emperor fell, his body gradually turned into a wisp of black smoke and dissipated between heaven and earth, as if he had never existed.

Everyone breathed a sigh of relief, except Lu Feng, who still looked solemn.

"Father is awesome! I knew he was the best!" Lu Sifeng praised.

"That's right. It doesn't matter whose father he is. How can my father, Lu Xiangfeng's, not be powerful? He is invincible in the world! The Demon Emperor is not even good enough!" Lu Xiangfeng said.

"Father, the Demon Emperor should be dead this time. He won't be resurrected again, right?" Lu Panfeng asked worriedly.

Lu Feng shook his head, looked ahead solemnly and said, "Take another look, I always feel something is wrong, have you noticed anything unusual?"

"Master, I found it..." Xiaolong said hurriedly.

Lu Feng was stunned. He had just been fighting the Demon Emperor with all his heart and soul, and had not observed much on the battlefield. Xiaolong and the others were relatively relaxed, and had more energy to pay attention to other situations...

"Xiaolong, did you find anything unusual?" Lu Feng asked in confusion.

"Master, I also felt something was wrong at first. How could there be so many demons in this sacred mountain? No matter how many we killed, there was no reduction in the slightest..." Xiaolong said.

"I also discovered that something is wrong. From the beginning to now, we have killed too many demons, but there has been no decrease in their numbers. I thought there was some formation at first, but I couldn't find it after searching for a long time..." said the orange cat.

"I'm afraid it's not because of the formation, but because I discovered that they can be resurrected infinitely. I deliberately memorized the appearance of a group of demons. I killed them countless times, and they are still alive!" Xiaolong said.

Everyone was shocked and looked at Xiaolong in disbelief.

"Xiaolong, are you sure?" Lu Feng asked in shock.

"Master, I am 100% sure. At first, I thought it was normal that the demon leaders were the same. Later, I observed them specifically and found that they were not exactly the same. Each had its own characteristics. So I concluded that they must have some means of resurrection..." Xiaolong said firmly.

Lu Feng frowned, thinking secretly in his heart, if the demons have the ability to resurrect infinitely, then this battle will become extremely difficult.

"Are they immortal? How is this possible..." Lu Panfeng said in astonishment.

At this time, Lu Panfeng on the side interrupted and said, "Perhaps, this resurrection is not unlimited. As long as we find their weaknesses, we can destroy them in one fell swoop!"

A trace of determination flashed in Lu Feng's eyes. "No matter what, we must find a way to crack it as soon as possible, otherwise the consequences will be disastrous. Everyone, disperse and look for clues. Once you find anything, inform each other immediately!"

Everyone followed the order and looked for clues in different directions...

At the same time, a wild laugh was heard.

“Hahaha… Stupid Human Emperor, have you finally discovered the clue? But you don’t have to waste your energy. Even if you find the reason, it’s useless. It’s just a waste of effort…”

Along with the sound of laughter, a figure walked out from the evil spirit again. Everyone looked at the person who came and was shocked again. Their hearts were as dead as death...

"Demon Emperor, you are resurrected again!" Lu Feng said gritting his teeth.

The Demon Emperor sneered, "Yes, I have endless vitality and can be resurrected continuously. How can you mortals compete with me?"

Lu Feng stared at the Demon Emperor, but he was not afraid.

Lu Feng knew that fear would only make him lose his fighting spirit.

But it was different for the others. Everyone was feeling like they were on a roller coaster. When Lu Feng defeated the Demon Emperor, their morale soared...

Now that the Demon Emperor has resurrected, many people feel hopeless and hopeless...

"So what if you can be resurrected? We humans have an indomitable will and will definitely defeat you!" Lu Feng roared.

The Demon Emperor laughed disdainfully, "Just you guys? You don't know your own limitations!"

As he spoke, the demonic energy on the Demon Emperor suddenly erupted, like a black storm, sweeping towards everyone at an astonishing speed.

The demonic energy was thick and powerful, carrying with it endless pressure and terror that made people feel suffocated.

Everyone's faces changed drastically, and they immediately realized the horror of this evil spirit.

They did not dare to be negligent at all, and they all used their strongest techniques and skills to try to resist the impact of this evil energy.

However, despite their best efforts, they found that their own powers were insignificant compared to the Demon Emperor.

The demonic energy was like an insurmountable mountain; their attacks and defenses seemed so fragile in front of it.

The crowd was defeated step by step. They were forced to retreat again and again by the evil spirit and could hardly stand.

Their faces were pale and their eyes were filled with despair and fear.

Faced with such a powerful enemy, they felt as if they were in a desperate situation.

But Lu Feng still stood there unmoved.

Lu Feng was observing and thinking, how did these demons revive?

Lu Feng understood that if he couldn't figure this out, then even if he killed more demons, even if he killed the Demon Emperor again, it would still be useless...

"Father, we can't resist any more, please come and help us..." Lu Nianfeng shouted.

"Master, have you discovered anything? Do you need our help?" Xiaolong asked.

Lu Feng's dazed expression suddenly brightened up.

The corners of Lu Feng's mouth slightly raised, as if he was sure of victory...

"No need, just hold on and take care of yourself. I think I should have found a way to crack it!" Lu Feng said confidently.
