"Hey hey hey, this can’t be good!"

  Arthur shouted loudly.

  The entire underground structure shook violently at this moment. Dust and gravel showered down from above.

  Anyone could sense that something was terribly wrong.

  In fact, the armed men had already begun to think of retreating—their attack rhythm slowing significantly.

  But both sides had gotten caught up in the heat of battle. Coupled with Morgar’s threats, they didn’t dare to retreat immediately. After all, it was just shaking for now—not actual collapse.

  ......

  In a hidden room on the bottommost floor of the underground structure.

  Boom!!!

  It shattered with a deafening crash.

  A storm from deep underground destroyed the hidden passage along the way and surged upward.

  "Hmm? It’s reaching the upper levels......"

  Seeing her surroundings, Hulim realized the danger. If the fight continued like this, Miko and Arthur might be caught in the crossfire.

  So Hulim deliberately left an opening.

  "Die——!!!"

  Morgar, driven mad by the battle and completely blind to reason, had long lost the ability to detect traps. He threw a punch without hesitation.

  Boom——!

  In an instant, Hulim was sent flying.

  She crashed through countless rooms and disappeared from sight.

  "Roar——!!!"

  Morgar roared up at the sky, then darted after her in a flash.

  "【......】"

  Soon, Hulim’s figure reappeared ahead.

  But in front of her, a pitch-black, lightless sphere materialized.

  "?"

  Though slightly confused, Morgar charged forward without a second thought.

  "Dark Prison Sphere!"

  The pitch-black sphere hurtled toward Morgar.

  "Trash like this!"

  Morgar punched the black sphere.

  But something unexpected happened.

  His powerful punch not only failed to shatter the sphere—his right hand was instead stuck to it, unable to pull back.

  "What?! "

  Immediately afterward, a terrifying suction force emanated from the sphere.

  The story has been illicitly taken; should you find it on Amazon, report the infringement.

  A vortex formed in the air, centered on the black sphere.

  The surrounding air and floating dust were the first to be sucked toward it, followed by gravel on the ground. Then the black flames on Morgar’s body were drawn away, and his trapped right hand twisted as if being torn apart.

  Moreover, the black sphere began to grow unstable. Terrifying waves of magic radiated from it.

  "D-Dammit!"

  Morgar tried with all his strength to break free. When he failed, he flew into a rage.

  "Against something like this——!!!"

  Hum!

  At a certain moment, the black sphere reached the limit of its stability and released immense energy.

  At the same time, Morgar unleashed his most powerful attack.

  Boom——!!!

  Pitch-black flames engulfed the black sphere, shooting upward like a black beam of light.

  In an instant, it pierced through floor after floor, reaching the topmost level. Then it tore through the thick earth between the top level and the ground above, bursting out of the ground, shattering the dome of the abandoned church, and soaring into the sky.

  ......

  "What...... was that just now......"

  Arthur said in a slightly trembling voice.

  "What on earth is happening here......"

  At this moment, everyone stopped fighting. They stared blankly and fearfully in the direction of the terrifying magic fluctuation.

  "T-That...... seems to have come from the bottommost floor, right......"

  One of the enemies fighting Arthur and Miko whispered nervously.

  "It does...... but......"

  "To pierce through the entire underground structure...... who could it be......"

  "I-It must be Lord Morgar! It has to be Lord Morgar!"

  "But...... Lord Morgar’s magic doesn’t feel like this......"

  For a moment, the crowd fell silent again.

  A question lingered in all the armed men’s minds.

  If it wasn’t Morgar, then who was it?

  What if it was the enemy......

  At the thought, some of the armed men began to slowly step back.

  "Hulim......"

  Miko’s eyes were filled with worry. She had no idea what was happening underground.

  She could only pray that Hulim hadn’t been caught up in it.

  "Wait, what if it’s someone here to help Lord Morgar? You all know Lord Morgar’s background......"

  Someone suddenly said in the crowd.

  As soon as the words fell, the retreating footsteps of many came to an abrupt halt.

  Right. What if it was one of their own? If they ran now......

  Everyone shuddered. They would definitely die if caught later.

  "T-Then what do we do now?"

  "What do we do? Keep fighting, of course!"

  Miko suddenly interjected, then waved her weapon and charged at the men.

  Worried about Hulim, she no longer wanted to be trapped here.

  "Ah, dammit! Has this woman gone crazy?!"

  "Forget it—take her down first!"

  "......"

  "Hah~!"

  Arthur shook his head with a smile, then raised his sword as well.

  "Don’t you guys forget about me——!"

  ......

  On the bottommost floor.

  Morgar now looked exhausted. The black flames that had always shrouded him had almost disappeared.

  Even in his demonized state, unleashing an attack close to Rank A power had taken an enormous toll on him.

  But perhaps his temporary weakness had allowed a shred of reason to return.

  "Dammit, did I make a mistake just now!"

  Morgar finally realized—Hulim’s attack had been troublesome, but if he had responded calmly, it wouldn’t have threatened his life. However, his lack of reason had led him to use far more power than necessary, leaving him in his current state.

  Boom——!

  At that moment, a dazzling white light beam suddenly shot from afar, hitting the weakened Morgar instantly.

  "Ah——!!!"

  Light Attribute magic, which is particularly powerful in attack among the seven elements and can restrain demons, combined to deal severe damage to Morgar with this Anode Ray.

  Thud!

  Morgar fell to the ground, his body smoking as if scorched.

  "D-Dammit......"

  He trembled violently, trying to stand up.

  "Truly resilient. Is this also an effect of demonization?"

  A voice came from ahead. Morgar struggled to look up.

  Hulim, who had been floating in the air, had flown close at some point.

  As she spoke, the white light in front of her grew brighter and brighter.

  "Anode Ray."

  "Ah——!!!"

  The white light beam hit Morgar again.

  In the beam, his body was continuously burned and vaporized.

  "I refuse to accept this!"

  Seeing that he was about to be completely eliminated, Morgar somehow stood up, enduring the pain.

  "I refuse to accept this——!!!"

  He roared up at the sky, then raised his clawed right hand, stabbed it fiercely toward his heart, and grabbed his demonized heart.

  Thud!

  By sacrificing the source of his life, immense power surged through his body—but his life entered its final countdown. Even if Hulim stopped attacking now, he wouldn’t live for more than a few minutes.

  He had abandoned his humanity for power, yet in the end, he had chosen such a fate.

  But......

  "This is enough!"
