Demons soon came striking the Inferno Kingdom. A fierce battle between humans and demons once again started.
However, the three Demon Monarchs didn't take the action at the start. They kept watching from behind.
As time passed, although the other two Demon Monarchs were still patient enough, Blood Demon Monarch could not control his hatred for humans, mainly for War God Dalgo who massacred all the demons.
He decided to take action himself.
"Rumble!"
Deafening rumbles resounded unceasingly. An incomparably terrifying force swept out in all directions, turning the surrounding mountains and ravines into a sea of disaster.
Countless crushed stones fell and the mountains collapsed. Terrifying energy spilled out and wreaked havoc. The scene was incomparably shocking.
It made all the experts present tremble in fear and their bodies couldn't help but tremble. The pressure of the Blood Demon Monarch seem to shake the sky and earth, and it was as if even the sky and earth were eclipsed in this great battle.
"Cough!"
Under Blood Demon Monarch's violent bombardment, the army of Inferno Kingdom was unable to withstand the impact of this terrifying force. They coughed out blood and their faces turned extremely pale. Thousands of them died immediately while hundreds of them were heavily injured and became incapable of fighting.
Even with the protection of a great formation set by the Fire Emperor, the powerful force still took away countless humans' lives.
This scene caused the faces of First Cycle Soul Ascension Stage expert Ming Ge and the other human elders of the Inferno Kingdom to turn solemn.
Just Blood Demon Monarch's attack alone had almost made them unable to withstand it. If the three Demon Monarchs attacked together, they were afraid that the Inferno Kingdom will be destroyed instantly.
Could it be that the Inferno Kingdom really had no way of surviving this catastrophe?
Even with the disposition of First Cycle Soul Ascension Stage expert Ming Ge and the others, they couldn't help but feel a sense of despair.
"Heh! Ants are ants after all. Even with such a powerful formation as your trump card left behind by Fire Emperor, you all are unable to exert its full power. Surrender now, don't put up such pointless resistance!"
Blood Demon Monarch laughed maniacally. His blood-red hair danced in the wind like a peerless devil god. It exuded a boundless pressure, causing the entire sky and earth to tremble continuously. Numerous cracks in the sky were torn open in a way visible to the naked eye. It spread across the entire sky, and it looked as if the sky had collapsed!
"Boom!"
As the wild laughter fell, an increasingly terrifying aura burst out from Blood Demon Monarch's body. Both of his hands were waving continuously, and bursts of blood-red light burst out from his hands. His blood and aura rushed into the sky. It condensed into a huge blood-red monster that circled around Blood Demon Monarch's body. It made Blood Demon Monarch look incomparably terrifying!
Boundless demonic energy surged out from Blood Demon Monarch's body continuously, adding to the body of the blood-red monster, his body became more and more solid.
Large demonic scales could be clearly seen, shining with a cold blood-red light. Boundless devilish might swept out, as if a true devil had descended, bringing a huge visual impact to everyone present.
"It's over!"
Blood Demon Monarch stood in the air, his scarlet eyes sweeping across the numerous Inferno Kingdom Experts. He sneered, raised his hands high, and then suddenly descended!
"Roar!"
A deafening monstrous roar instantly resounded across the entire world. Following the roar, the huge monster immediately rose into the sky and circled in the air, emitting a boundless bloody glow. In an instant, it swooped down towards the experts of Inferno Kingdom.
A power that was like a vast ocean was unleashed from the body of the blood-red monster, creating a huge pitch-black crack in the void. Even from a distance, one could feel the terrifying monstrous might.
It was as if the entire world had turned into the home ground of the blood-red monster.
Endless monstrous might swept out and the area of several tens of thousands of kilometers turned into a sea of storms. Everything within this area was swept by the storm. Everything was destroyed.
If it wasn't for the protection of their respective experts and the great formation left behind by the Fire Emperor, the humans of Inferno Kingdom would have been wiped out by this storm.
The blood monster roared and directly smashed down. The powerful monstrous might caused the pupils of First Cycle Soul Ascension Stage expert Ming Ge and the rest to shrink. All of them poured out all their strength into the formation, waiting to bring forth the formation's true might.
"Rumble!"
Under the gazes of everyone present, the blood monster and the light barrier formed by the combined strength of humans collided.
It burst forth with shocking force, and then, a deafening sound exploded. A storm formed by terrifying power appeared and wreaked havoc like a tornado, destroying everything in the surroundings.
The blood-red light intertwined with the light of the formation left behind by the Fire Emperor, lighting up the entire Inferno Kingdom. However, underneath this beautiful scenery, there was an endless amount of killing intent hidden within.
The human army who were maintaining the formation felt a terrifying force sweeping towards them, causing their faces to flush red. Blood spurted out uncontrollably, and they couldn't withstand it any longer. They were sent flying away.
"Bang! Bang!"
Sounds of collisions were heard one after another. It was unknown how many humans could not withstand it. The entire Formation could no longer be maintained any longer. It broke apart one after another, turned into specks of light, and dissipated in this world!
Although this collision had successfully blocked the blood light that Blood Demon Monarch had unleashed, it had also destroyed Formation left behind by the Fire Emperor, exposing many experts of the Inferno Kingdom to Blood Demon Monarch's terrifying Immortal Realm power!
Without the protection of the formation, the terrifying demonic pressure was like a mountain that was tens of thousands of meters tall, pressing down on Ming Ge and the others. Even someone as strong as Ming Ge who was at the First Cycle Soul Ascension Stage couldn't withstand this terrifying pressure. He fell to the ground, unable to move.
In front of the Celestial-ranked Demon, these weak humans were no different from ants. Yes, they were all like ants.
"What other trump cards do you have? Continue to use them, let this Demon Monarch enjoy himself!"
Blood Demon Monarch stood in the air. His body was shining with blood-red light, like a demon god of blood. His scarlet eyes were filled with disdain. He laughed loudly, and his voice resounded throughout the entire world.
Not far away, Dragon Monarch's eyes flickered with an unnoticeable sense of disappointment when he saw how the Blood Demon Monarch has acted. Shadow Monarch also shook his head.
He had clearly ordered for Demon Monarchs to not take action currently. They were planning to wait in order to see if Fire Emperor will come or not. If he comes, they would surround him and kill him immediately.
To do that, they do not want to exhaust their strength in a meaningless battle at all.
But Blood Demon Monarch ignored his order and took action, not to mention, he was showing off his strength one after another.
If he wanted, he could have already destroyed the Inferno Kingdom with his strength, however, Blood Demon Monarch instead was playing around, wasting his demonic energy.
"Boom!"
"Those who want to destroy my Inferno Kingdom will die!"
Just as Blood Demon Monarch was about to go wild once again, an extremely powerful aura suddenly came from the distant sky. Along with this powerful aura, a loud and clear sound was heard.
This sudden change caused Blood Demon Monarch and the others to be shocked. All of them focused their eyes and looked over.
A glimmer of hope flashed across the eyes of Ming Ge and the others who were in despair. They looked in that direction. They could feel that this terrifying aura was actually on par with the aura that came from Blood Demon Monarch's body!
"Swoosh!"
Under the crowd's gaze, the sound of air being torn could be heard as an aurora shot out. In the blink of an eye, it transformed into a figure that stood in the sky. A majestic aura spread out from his burly body, and it was a match for the ferocious aura unleashed by Blood Demon Monarch!
"Your Majesty, Fire Emperor!"
When they saw the person's face clearly, Ming Ge and the others cried out in surprise and overjoy.
They thought that when something happened to Fire Emperor in Mouth of Abyss, it was unknown whether Fire Emperor was alive or dead. However, they never thought that Fire Emperor would come back at their most desperate moment.
The terrifying aura that burst out from Fire Emperor's body made Ming Ge and the others tremble. At the same time, they were also excited.
