The broken heart of the strongest demon

Sirzechs felt surprised and stunned by the turn of events. He didn't expect that his magic, which he had always considered one of the most destructive bloodline magics, could be easily extinguished by the thin barrier before him.

In his confusion, Sirzechs began to question his own strength and abilities. Until now, he had relied on POD magic as his trump card, believing that its power was unmatched. However, the battle against Petra opened his eyes to the reality that his power had its limits, and there were others out there who could confront it with skill and strength comparable to his own.

"Oh my~... I don't know how Grayfia could resist you, but if you want to talk to me, you should cool your head first," Petra said with a sharp and dangerous glint in his eyes directed at Sirzechs.

The young Gremory lord instantly felt a cold shiver running through his body, triggering a sensation that made him shudder. He then launched another attack with a stronger force, a power concentrated at one point.

"Hey-hey! If you shoot something here, those below will be affected too... Shsss! It seems you're stressed because of a broken heart," The magus whispered as he prepared a spell that would make them move to another location.

With confident strides, Petra entered deep meditation, his voice softly chanting, calling upon the powers of the universe to shape a new world around them. The radiant light enveloped the space, depicting a new dimension formed around Petra and Sirzechs, as if they had been invited into Petra's realm of mind.

Realization Realm Mind - Verdant Vale

A stunning verdant valley stretched out before them, nestled among majestic mountain peaks. Lush green forests crept around, bringing forth a fresh aroma that filled the air. Glittering rivers meandered amidst the green grass, and the roar of waterfalls provided a magnificent backdrop.

Yet, amidst the beauty, two silhouettes still stood upright, between two valleys. Petra was familiar with this place, his strongest inner world emanating deep memories. Sirzechs, however, felt a sense of strangeness enveloping him. The energy that usually flowed abundantly was now cut off, as if drawn by an unknown force, leaving him in deep confusion.

"Damn..." Sirzechs muttered with uncontrollable disappointment. "What have you done, magus? How could I lose most of my energy like this?"

Petra turned his gaze, his expression pleading yet firm. "This is my inner world, Sirzechs. Your energy is drained because of the unpredictable power of this place. You must rely on your own inner strength here." His voice remained gentle, but contained undeniable certainty.

Petra looked at him sharply, but also with a questioning expression. "You didn't realize? This world is my creation. Here, I am the one in control."

Sirzechs pondered for a moment, struggling to digest the information. He felt trapped in a world created by his opponent, a world where his power was no longer as strong as he had hoped.

"So you decided to cut off my demonic energy source from the outside world? No wonder why everyone calls you Vegeance Magus, someone who rudely messes with magic itself," Sirzechs said, his eyes still fiery despite his energy now only half of what he had.

Petra chuckled at the young Gremory lord's remarks. "Ckckck~ I don't care about that nickname, but I think it's not bad." Then Petra raised his magic staff, Voldemort. "Here we can fight without fear, and I can cool your head, Sirzechs," he said.

Sirzechs clicked his tongue upon hearing that. "It's up to you, whatever you do, my goal won't change. I can definitely kill you," he said with a dangerous look.

Then the battle continued with destructive magic attacks that damaged the beauty of the land. Fortunately, the place was only Petra's realm of mind, not a real location. Sirzechs unleashed several long-range spells with his POD, destroying swathes of land and sending shockwaves that shook Petra's created universe.

Sirzechs continued to attack Petra with the Power of Destruction, each attack sending shockwaves that shook Petra's created world. However, Petra anticipated each attack carefully, skillfully using his Union magic to confront them.

"You're like a dog that keeps barking, Sirzechs! But unfortunately, your bite is not as strong as your bark!" Petra taunted, dodging attacks agilely.

Sirzechs felt increasingly angry, his usually calm demeanor disrupted by the taunts. His face flushed red, his eyes blazing with overflowing anger. "You...!" he shouted, before unleashing even more ferocious destructive attacks.

"KAKAKAKA~ It's pointless, anyway, fire will still be extinguished by water, whatever you want with that fact, Sirzechs?" Petra teased with a mocking tone that fueled Sirzechs' emotions even more.

The veins on Sirzechs' temples began to protrude as he heard the taunts from the magus, making him unable to bear it any longer. With overflowing rage, he played his trump card. Dark aura began to envelop his body, and the attacks he launched seemed more ferocious than before.

"You will regret trying to challenge me, Petra!" Sirzechs hissed, his voice full of hatred and determination. With quick movements, he unleashed his powerful attacks towards Petra, aiming to destroy everything around him.

Sirzechs played his trump card, Human-Shaped Aura of Destruction, the original form that depicted the true power of Destruction that destroyed everything, regardless of his will. Before Petra, his body began to change, shrouded in a thick dark aura, and in an instant, Sirzechs transformed into a frightening entity.

His form now became a terrifying representation of unstoppable destructive power. His body was enveloped by swirling waves of darkness with devastating intensity. His eyes emitted a fiery red light, reflecting boundless rage.

Sirzechs, in this new form, was like a direct manifestation of destruction itself. Every movement he made caused powerful vibrations, and every gaze promised doom to anyone who dared to challenge him.

Petra looked at him with admiration and awe, but also with a hint of concern. Sirzechs' new form had succeeded in making his Realm Mind tremble greatly, sending waves of power that he had never felt before.

In his mind, Petra thought, 'This person, to make my created world tremble like this, truly deserves to be called the strongest Lucifer in history, surpassing the past Lucifer.'

Despite facing extraordinary power, Petra maintained his steadfast attitude. With his characteristic bravery, he prepared to face his greatest challenge yet, fighting against the strongest Lucifer that ever existed.
