"Boom!"

Dragon Demon Monarch and Shadow Demon Monarch exchanged a glance and saw the cold look in each other's eyes. And after that, a powerful pressure burst out from their bodies, pressuring the entire world. It was as if millions of tall mountains were pressing down on them, causing the entire world to be filled with intense pressure.

In an instant, Dragon Demon Monarch and Shadow Demon Monarch formed seals with their hands. Boundless energy swept out, turning into a torrent of energy that crashed down toward Fire Emperor. The boundless energy was killing everything in its path, causing the entire heaven and earth to change color.

Facing this terrifying attack, Fire Emperor's facial expression changed dramatically. He hurriedly circulated the energy in his body and defended himself with all his strength.

He could still launch an attack when facing Blood Demon Monarch alone, but when Dragon Demon Monarch and Shadow Demon Monarch attacked, he could only defend passively. He might not even be able to defend himself.

"Boom!"

A boundless energy burst out from Fire Emperor's body, causing his entire body to burst out with a bright light. The majestic energy condensed into a huge light barrier that enveloped Fire Emperor, blocking the terrifying attacks of Dragon Demon Monarch and Shadow Demon Monarch.

"Bang!"

Under the worried gazes of Ming Ge and the others, Dragon Demon Monarch and Shadow Demon Monarch's terrifying attacks crashed down with a loud bang. It was like a tidal wave that swept out in a visible manner.

With Fire Emperor as the center, in a radius of ten thousand miles, everything was enveloped by this terrifying energy, and everything was destroyed. Even the protective shield conjured by Ming Ge and many other human experts together was trembling because of this force.

Fortunately, Fire Emperor was still protecting the entire Inferno Kingdom from powerful impacts.

"Puff!"

A powerful rebounding force swept over, causing Fire Emperor's face to turn pale. Blood was no longer able to be contained. It spurted out from his mouth, causing his entire body to tremble uncontrollably.

Fire Emperor felt as if his internal organs were going to be shattered by that terrifying force. A severe pain struck his heart, causing him to break out in cold sweat.

"You think you can protect the Inferno Kingdom with just you alone? What wishful thinking!"

Dragon Demon Monarch stood in the void with his hands behind his back. His entire body was emitting a domineering aura that looked down on the world. He stared coldly at Shenrong and said with a sneer.

Although Shadow Demon Monarch didn't say anything, he looked down at Fire Emperor like a god. His eyes were full of disdain, as if he was looking at an ant.

"Boom!"

Blood Demon Monarch also reacted. With a flash, he landed next to Dragon Demon Monarch and Shadow Demon Monarch. He also looked down at Fire Emperor with a ferocious smile on his face.

As a Celestial-ranked demon, being injured by a human like Fire Emperor was the greatest shame in his life. If he couldn't get his revenge, how could he have the face to stand tall in this world?

In this short period of time, dozens of ways to torture people flashed in Blood Demon Monarch's mind. He wanted to let Fire Emperor experience what it meant to be cruel and what it meant to be better off dead than alive.

Fire Emperor's eyes were cold as he stared at Dragon Demon Monarch, Shadow Demon Monarch, and Blood Demon Monarch in the sky. His body was emitting a powerful aura. Even though he was severely injured, he was still incomparably strong and fearless.

"With me here, you won't be able to hurt the Inferno Kingdom. If you want to exterminate the human race, you will have to step over my body!"

Dragon Demon Monarch and the other two Demon Monarchs looked at each other. When they saw the ruthlessness in each other's eyes, Shadow Demon Monarch sneered and shouted in a deep voice, "Since you are courting death, the three of us will fulfill your wish!"

"Boom!"

As soon as Dragon Demon Monarch's voice faded, he and the other two demons unleashed their powerful energies. Boundless blood mist, the phantom of a demon dragon, and the shadow of a humongous devil appeared that instantly shook the sky.

A terrifying power swept across the entire Inferno Kingdom, causing all humans to appear as the protective barrier was torn apart. Everyone's heart trembled. The power of celestial-ranked demons had completely erupted. It caused the entire world to tremble, as if the heavens and earth were afraid of this power.

"Boom!"historical

Facing the eruption of the three Celestial-ranked demons, Fire Emperor showed no signs of weakness. A strength that was like a vast ocean gushed out, and the next instant, a Flame Dragon and Flaming Phoenix could be seen manifesting behind his body.

A powerful aura, that swept across the heavens and the earth, suddenly erupted from his body. The image of a Flame Dragon and a Flaming Phoenix appeared behind him.

Dragon roars and phoenix cries were emitted from his body, shaking the hearts of all the humans and demons present.

"Buzz!"

Fire Emperor stretched out his hand and grabbed it. A fiery red long sword appeared in his hand. The aura that burst out from his body soared into the sky. His combat intent had reached its peak. The phantom of the Flame Dragon and Flaming Phoenix behind him made Fire Emperor look like an ancient flaming god. He was valiant and matchless.

"Today, don't even think about touching my Inferno Empire!"

A loud shout was heard. Fire Emperor's entire body was lifted up from the ground. The longsword in his hand seemed to have turned into a sharp weapon that could strike the sky. He slashed out fiercely and a wave of wailing sound was heard.

Dragon Demon Monarch and the other two Demon Monarchs slightly narrowed their eyes, and their bodies unleashed monstrous devilish might.

An ice-cold aura swept out, freezing the surrounding into ice crystals. Cold energy swept out and it seemed as if the entire world had turned into the Ice Snow World.

"Boom!"

The long sword slashed down, sending out endless sharp blades. Ice crystals collapsed and splashed across the sky. The surrounding mountains suddenly collapsed, and many mountain rocks exploded.

Dragon Demon Monarch and the other two Demon Monarchs shouted at the same time and collided with the long sword.

"Bang!"

A deafening explosion resounded throughout the entire world.

Fire Emperor and the other three demons were fighting each other. They kept colliding with each other. Every time they collided, the entire world would tremble. It was as if the heavens and the earth had been split open, bringing tremendous shock to everyone present!

As Celestial-ranked demons, they should be standing above everyone else in this world of humans. But in this tiny Inferno Kingdom, they were blocked by a single person constantly.

This irritated them a lot and made them furious.

How could the undefeated pride in their hearts be broken by a mere human like Fire Emperor?

No matter what, they had to crush Fire Emperor. Otherwise, their reputation would be ruined!

"Boom!"

Fury erupted from Dragon Demon Monarch and the other two Demon Monarchs like a volcano.

The three of them rushed out once again. Their bodies glowed with a demonic light. Each of their feet stepped on the void. A huge black hole was created in the void. The energy that was being waved in their hands was getting stronger and stronger. They were determined to kill Fire Emperor here.

"Bang! Bang!"

The fierce battle between Fire Emperor and the three demons shook the world.

Their speed was extremely fast. Others could only see four rays of light colliding with each other. They couldn't see the figures of the Fire Emperor and the three demons clearly.

In just the blink of an eye, their battle was already dragged to thousands of miles of land, causing the mountains and rivers within these miles to collapse.

After some time, when the four of them separated for some time, Dragon Demon Monarch and the other two demon monarchs stared at Fire Emperor in disbelief, their faces trembling.

Obviously, Fire Emperor's body had been badly beaten by them. His whole body was covered in blood, but Fire Emperor was still extremely strong.

Not only did his aura not weaken, but it also became stronger and stronger. His desperate attitude had shaken them all.

They were determined to kill Fire Emperor, however, at this moment, they suddenly felt something and looked in the direction of the abyss.

"This... How could this be?"

The three demons were incredibly shocked and frightful expressions appeared on their faces that confused Fire Emperor, for he could not understand what suddenly happened that made these three fierce demons react like this!

"How could the abyss be destroyed?" The three demons exclaimed together, and the next moment, ignoring Fire Emperor, they rushed in the direction of Mouth of Abyss at their fastest speed.

However, before they could even cross the land that have been destroyed because of their battle against Fire Emperor, the three of them suddenly felt something, and then their bodies exploded.

The three Celestial Phenomenon Stage demons died just like that!
