The Infinite Powerhouse Mixed in with Sakura Dormitory

"Kuroie, don't make a move yet. Pay attention to everything happening on the battlefield and analyze the opponent's strength and power system."

Roar!

Rias's three demonic lions roared, their massive bodies thundering as they ran to the forefront of the army: "All demons, obey my command! Form the first formation and charge with me!"

Hoho! !

At Rias's command, the demon warriors riding the Nightmare Horses scattered as they ran through the air, forming the shape of a bat with outstretched wings.

At the same time, all the demon warriors were enveloped in a layer of red magic. With their power and spiritual energy connected, the entire army was covered by a red array domain that spanned several miles.

Just as Rias's legion began its charge, Souei and Rimuru's other four students also appeared above the orc formation.

Seven powerful individuals, possessing the strength of a Demon King or awakened Demon King, stood together, their expressions solemn as they watched the legion charging towards them with the force of a mountain collapsing and a tsunami crashing down.

The first to attack was Benimaru, who rubbed his hands together and threw out two flames containing terrifying magical energy. That was his awakened skill, Yangyan Baoyu, which had the ability to incinerate everything along with a barrier.

Next up was Diablo, who appeared above Rias's army with a terrifying, oppressive magical aura emanating from his hands, accompanied by a black dot that seemed to emanate from a volcano. He then activated his awakened skill, Dark Magic Burst.

Boom! Boom!

Just as Benimaru and Diavolo's long-range attacks landed above the military formation more than ten miles away, they were blocked by the red array field. The attacks, comparable to those of a King-level expert, had no effect other than causing the surface light shield to tremble slightly.

"What kind of skill is this?" The group of people, who had never seen such a large-scale military formation before, were all stunned.

However, Rias, whose movement speed had surpassed the sonic boom, had already led her legion and appeared a few miles away from them in just a few breaths, having traversed ten miles.

Just three miles away from Benimaru and his group and the orc defensive formation ahead, Rias raised her right hand high, and a magnificent yet dangerous divine sword appeared in her hand, which she then slashed down with.

As Rias swung her sword, all the demon warriors of the Gremory family also swung their weapons in unison, slashing forward.

Boom boom boom boom!!

In an instant, streaks of red sword energy, saber energy, and spear energy, each a hundred meters long and exuding an astonishing aura, slashed out from the military formation. Each one radiated the power of an ordinary demon king, obscuring the sky and causing Benimaru and the others to change their expressions drastically.

They might not care about a single attack, but when faced with thousands of catastrophic attacks at the same time, even they wouldn't dare to take them head-on.

"Be careful"

"Get out of the way"

Boom boom boom boom!!

The sky was filled with destructive sword energy that engulfed the area in front of them. After unleashing the first attack method of the military formation, Rias, who controlled the formation, gave her opponents no time to breathe. With a thought, her voice rang in the ears of all the demon warriors.

"Unleash the second combat form."

"Roar"

The massive army's wings folded together, and a layer of tangible red crystalline light appeared on all the demon warriors, instantly linking them together and transforming the entire army into a sharp red crystal triangular arrowhead.

Then, the three demonic lions beneath Rias roared to the sky, and with a thought from Rias, they burst forth at their maximum speed, leading the entire army to charge forward, breaking through into supersonic speed in the blink of an eye.

Just as the giant triangular arrow was about to strike the aftershocks of the previous overwhelming attack, Rias, acting as the arrowhead, slashed down with her sword once more, and the demon warriors behind her also brandished their weapons in unison.

This time, however, it wasn't a sky full of sword energy, but a massive, solid, blood-red sword energy a thousand meters long that slashed out from the military formation, carrying a destructive force that tore through space, and fell towards the heads of Benimaru and his group who had just blocked the previous wave of attacks.

This sword energy, which gathered the essence and spirit of ten thousand three-star and four-star demons, unleashed power barely comparable to a strike from an ordinary god-level being, thanks to the massive array created by the Gremory family using vast resources.

Before it even landed, Benimaru and the others below, who were in a very sorry state, along with the remaining 10,000-odd pig-headed men out of the original 50,000, were unable to move under the oppressive force of that terrifying sword energy.

Most importantly, under this attack, the space they were in was sealed off, making it impossible for them to escape. They could only withstand this attack, which was comparable to Milim's full power.

"Dragon Star Expansion Explosion".

Just then, Milim, who had been asked by Rimuru to do so in the distant sky, made her move, unleashing a series of dazzling starlight beams that intercepted the destructive sword energy halfway through its path.

Boom boom boom boom!!

A deafening explosion erupted in the sky in an instant, and the terrifying aftershocks stirred up dust that engulfed the central battlefield.

Just as Rias's legion attack was stopped by Milim, the situation for Shion and the others on the other two sides became much more serious.

Because they were facing an elite demon legion that had deployed its army, led by two outstanding new-generation geniuses from the Underworld who had repeatedly entered the forbidden zones and fought their way out, completely different from Rias, who had never entered the forbidden zones.

Even as they were still charging, the two demon legions unleashed a barrage of ordinary legion attacks to suppress Ziyuan and her companions. At the same time, their central and rear forces were constantly gathering power, and the dangerous aura emanating from them terrified Ziyuan and the others.

Whether it was the heavy cannon sword energy that ripped the earth apart with the ship-slaying sword in Shion's hand, or the powerful awakened skills of Primordial Purple and the others who came to assist her, they were all blocked by the formation domain covering the legion.

Although the array domain trembled continuously, it was unable to truly destroy the domain that linked ten thousand elite three-star and four-star demons.

Before they could think of any other way or avoid it, the demon legion, moving at the speed of sound, approached the defensive camp of Ziyuan and her companions in just a few breaths.

Then, he directly drew upon the power of the legion's formation, unleashing a legion attack comparable to the pinnacle of this world at the level of an ordinary main god, causing the world to lose its color in an instant.

Without Milim's help, the left and right sides were directly overwhelmed by the terrifying attack that destroyed everything and shattered space, and the defensive formation was directly breached, and the situation was hopeless.

Seeing his subordinates unable to withstand even a single blow from the elite invading legion of the otherworldly forces, Rimuru's expression turned extremely grim, and he let out a low growl.

"Everyone retreat."

boom!

Rimuru unleashed a terrifying magical power as a pair of dragon wings spread behind him, instantly darkening the entire sky. Tornadoes crackling with black lightning descended from the heavens, destroying everything in their path.

As the strongest being in this world, Rimuru's power is different from that of Benimaru and the others. Each of his black lightning death tornadoes is equivalent to the divine power of an ordinary main god.

The target was Dihouser Belial and his companion, who had breached the defenses on both sides and were preparing to cut off and annihilate all resistance. At the same time, more than a dozen destructive wind dragons descended from the army led by Rias.

The death tornado tore through space and destroyed everything, forcing Dihouser Belial and the others to deploy a defensive formation. Immediately, a huge demonic figure slowly rose above each formation.

After unleashing the Black Lightning Death Tornado, Rimuru produced a lightning ball resembling a black hole in his left hand, which probed into the void and appeared above Rias's army.

In an instant, terrifying gravity and destructive lightning erupted. The gravity collapsed, and the ground outside Rias's commanded military domain was directly torn apart. The entire military domain trembled violently.

At the same time, Rimuru pulled with his right hand, creating a transparent spatial slash that struck the army commanded by Seraorg Baal.

In an instant, a spatial rift ten miles long appeared above the Seraog demon legion, silently annihilating the phantom of the demon god protecting the army.

"Your opponent is me."

Just as Rimuru single-handedly suppressed the three demon legions, the area centered on the World Passage, spanning over twenty miles in front and behind, and hundreds of miles in radius, that had been corrupted by the will of the underworld, trembled violently.

A terrifying will, filled with the aura of destructive rules, surged forward.

Boom boom boom boom!!

When the will of Sirzechs Lucifer, who embodies the rules of destruction and represents the will of the underworld, descends, the world suddenly erupts in a violent reaction.

The sky above the World Passage was shrouded in boundless black clouds, from which roared countless ten-thousand-foot-long purple lightning dragons, constantly descending in an attempt to drive Sazex away.

"roll."

With a low roar of Sazex's will, a destructive magical force soared into the sky, tearing the dark firmament apart and scattering the clouds and lightning. Its demonic power was overwhelming.

Such imposing presence immediately made Rimuru's expression turn extremely solemn.

The will of destruction gathered above the World Passage, transforming into a black figure a thousand meters tall, with thirty-six pairs of demonic wings behind it and nine pairs of sharp horns on its head.

After his will descended, Sazex struck down with a palm, and a destructive dragon roared forth from beneath his palm.

boom!

The black hole above Rias's army was swallowed up by a demonic dragon, and the spatial rift above Seraorg's army was violently destroyed by the dragon's tail.

Then Sazex looked at Limru, who was more than 30 miles away, and threw a punch.

Hoo hoo hoo!!

Nine thousand-foot-long demonic dragons, formed entirely from the rules of destruction, roared out, causing the space in their path to collapse and transform into a black dragon path. The laws of heaven and earth retreated, and their demonic power was overwhelming.

boom!!

The roar of the dragon formed from the nine rules of destruction was so powerful that everyone present, except for Rimuru, Mirium, and Chloe, gasped for breath, feeling as if they were suffocating and facing death.

"So strong."

Rimuru stared solemnly at the attack that had locked onto his location. His aura surged once more, and he was enveloped in silver light as if he had stepped into time itself.

A long sword appeared in Rimuru's hand, crackling with black lightning and blue flames. Though he was small, he gave everyone a sense of incongruity that seemed to fill the heavens and earth.

puff!

Rimuru swung his sword down, the tip of the blade disappearing and reappearing on the head of a demon, silently slaying it. Then came the second and the third strikes.

There were no earth-shattering explosions or apocalyptic phenomena. Rimuru, shrouded in silver light, simply swung his sword, and the destructive dragons vanished along the way.

However, Rimuru would take a step back after slaying each dragon. After all nine Destruction Dragons had vanished, Rimuru had already retreated nine steps in the air.

At this moment, Rimuru's expression was very solemn. In his perception, the other party's realm was similar to his, but the power the other party possessed was tenacious, domineering, and full of destruction, requiring him to consume twice the power of the rules to counteract it.

Sazex did not continue to attack. Looking at the blue-haired girl who was more than 30 miles away and outside the range of the Underworld's will, he said calmly, his thoughts vibrating through the air: "You are very strong."

"You are very strong too." With dragon wings flapping behind him, Rimuru also exuded his own supreme will, his spiritual power spreading as he spoke in a deep voice.

When the two stopped fighting, Rias and the others below also restrained their auras and quietly watched as Benimaru and the disheveled Shion and others reorganized their remaining forces without pursuing their victory.

At this moment, the avatar of Sazex's will began to change, eventually transforming into a demon king with thirty-six pairs of black wings, long blood-red hair, and a height of ten meters.

"I am Lucifer, the ruler of the underworld, and I have come to this world to conquer it," Sazex declared.

Rimuru, seeing that Sazex had stopped after attacking once, said defiantly, "I am Rimuru Tempest. With me here, your invasion is doomed to fail."

“Oh, really?” Sazex nodded noncommittally, then fell silent.

Sazex fell silent, and Rimuru, who had nothing to say, also fell silent, staring at him quietly as his Wisdom King skill was frantically running, analyzing all the information on the battlefield.

The battlefield, which had been raging fiercely just moments before, fell into an eerie silence, with only the sounds of retreating demon troops running and the commotion of demons from the underworld.

"Lord Rimuru." More than ten minutes later, Benimaru, Diavolo, and the others, whose troops had all withdrawn from the battlefield, flew up, their expressions all very solemn.

"Lord Rimuru..." Shion, who was also somewhat disheveled, looked at Rimuru with a downcast expression, because the troops she led had suffered heavy casualties.

Rimuru closed his eyes, and when he opened them again, he reached out to stop Shion and the others from speaking: "Now is not the time to talk, Benimaru, order a full retreat to the Federation Empire and abandon the southern part of the forest."

“My lord, this…” Benimaru and the others were taken aback.

“This is an order,” Rimuru said sternly.

"Yes." Benimaru and the others accepted the order and flew down.

As Rimuru slowly retreated, the Underworld simply watched quietly, showing no intention or plan to pursue them, which relieved them, but immediately made their hearts even heavier.

Because the other side was too cautious.

"Lord Rimuru, are we just going to give up on the South like this?" The group flew in the sky. Souei looked at Rimuru with some confusion, while the others also had some resentment on their faces.

Although they were temporarily suppressed by the other side, it was only because they were unfamiliar with the other side's fighting style. In fact, their losses had not yet reached the point of being crippled, and their overall strength was not inferior to that of the other side.
