Starting with magical girls, I'll reign supreme for eternity.

The filthy magic that is transformed from people's negative emotions is just a few fragments that fell from her body.

Those faint, ethereal auras emanated from her, then subsided, transforming into a power akin to the very essence of the world, omnipresent.

It is not that people's negative emotions have transformed into filthy magic.

Rather, it was the person's negative awareness that activated the foul magic she had released, which is how she gained such power.

That's true; no matter how you look at it, energy isn't conserved during emotional transitions.

The main corrupted magic is not a miracle like that of a magical girl; basic physical laws still apply.

So Shion asked curiously, "Excuse me, do you have any extras?"

【Iris】tilted her head, looking curious, "What do you mean by 'single-multiple-nothing'?"

"Are you at the single-universe level? Or the multiverse level? Generally speaking, infinity is not allowed to be included in the scope of the debate, nor can true infinity be applied to the single-universe level, because true infinity in the mathematical sense is still outside the scope of the debate. True infinity is not the same as infinity in the debate. Infinity in the debate level can generally be considered as a normal universe..."

After a long silence, Iris finally said honestly, "I don't understand."

"There's no other way; we need to be more precise when it comes to combat power." As Ziyuan spoke, her aura clearly surpassed that of her opponent, explaining the specific settings like a teacher. "A single entity means destroying an infinitely large universe in one strike; a multiverse means destroying a multiverse in one strike. Of course, there are also super-single-universe levels, which can destroy a multiverse in a given amount of time, though the time varies. And multiple entities, which can be described as being many times the size of a single-universe..."

【Iris】turned her head to the side, and countless eyeballs appeared in the sky, blinking and flashing the images of countless worlds. "I don't understand. You can see for yourself. These are all the worlds I destroyed."

It felt somewhat like taking out a treasured item for appraisal, and I was even looking at Shion with great anticipation.

Ziyuan stroked her chin and counted carefully. "Hmm, what a pity. It seems we won't reach the level of the Infinite Box."

【Iris】 didn't feel sorry, only slightly surprised, "An existence at the level of the Infinity Box is stronger than me?"

"More or less. Yours is at most at the level of a super single universe, because you can't destroy so many universes in one blow, right?"

Regarding Shion's evaluation and certification, the Beast of the End nodded, "I need to personally travel to different universes and spend some time before I can completely devour them."

Ziyuan clapped her hands and exclaimed, "That's right, it's at the level of a super single universe. Not bad. With your strength, you might surpass the Great Emperor and be called an Immortal."

Although she couldn't understand the words, Iris could still hear the praise and admiration in the other person's tone.

The Beast of the End smiled and nodded, "Then it seems I am indeed quite good. But I'm curious, can we use the classification 'slightly weaker than a single universe, slightly weaker than a multiverse'?"

On the one hand, Shion was slightly surprised that the other party understood so quickly; on the other hand, she scoffed at how far the other party's understanding was from the wrong conclusion.

"The so-called weak single universe and weak multiverse are pure nonsense. The standard for a single universe is to destroy an infinitely large universe with one blow. The same applies to the multiverse. The minimum standard has been given. Where does this weak single universe and weak multiverse come from? I think it's mostly idiots."

After being mocked, the Beast of the End was not angry, but simply asked again, "Is the highest level the Infinite Box?"

"Infinity is 3 points for repeated infinity emphasis, 3.5 points for double infinity, 4 points for maximum numbers, 4.5 points for partial properties of infinity or large numbers, at least greater than 10^100, and 5 points for being comparable to natural numbers or similar..."

"That's really meticulous."

"Combat power is mathematics," Ziyuan said seriously. "Mathematicians, physicists, and even philosophers throughout history have invented various concepts and formulas for the sake of combat power. The history of mankind is the history of combat power mechanics."

So Iris thought for a moment, "By this standard, even at her strongest, Miss Iris didn't reach the level of a single universe, but her performance was still outstanding."

Finally managing to steer the conversation away from the division of combat power, [Iris] waved her hand, and the two of them left the garden and arrived at a world full of devastation.

They walk above the world, surveying everything.

Terrifying, corrupt magic engulfed the universe, leaving behind widespread erosion and destruction.

Every living thing in the universe bows down to it, and no one can stand before it.

There was only one exception.

Even though she was covered in wounds and her magical armor was tattered, the blue magical girl was still a sight to behold.

The last magical girl the Beast of the End faces.

In fact, they did not only meet once.

When the Beast of the End descended, Iris stood in its way.

"I am the world's strongest magical girl, Lady Iris!"

The first time I heard it, the arrogant voice still carried a hint of immaturity; beneath the arrogance lay the ignorance of a novice.

At that time, she had many companions around her.

Claiming to be the world's strongest magical girl sounds more like boasting and ostentatiously announcing her power.

Even so, the flamboyant iris still gave the magical girls, who could barely stand in the face of the Beast of the End, immense courage and reassurance.

However, in the end, they still lost.

It was just good luck that I didn't die.

This reminded Shion of the first time she fought Iris.

However, compared to Shion, the Beast of the End is obviously more cruel—or perhaps not cruel, but simply crushed many other magical girls indiscriminately.

Golden tea, camellia, red cotton, mochi, Sakiyu, red apricot, long moon, Xiaoxiao, Zimo...

The iris, having failed to protect anyone, fell pitifully to the ground.

It was no different from countless other ants.

"I have always been, the world's strongest magical girl, Iris!"

The second time was when Iris returned to face the Beast of the End once again, by which time the Beast of the End had already devoured many magical girls and worlds.

Iris, whose injuries had just healed and who had regained some of her strength, once again stood in front of the Beast of the End without hesitation.

Qingluan stayed by her side, but she was actually filled with fear and unease, and was even so overwhelmed by the aura of the Beast of the End that she could hardly breathe.

So Iris smiled brightly, holding Qingluan's hand, and declared this.

In reality, much of the ignorant arrogance in his tone had disappeared; it was more like he was forcing himself to believe it.

This time she didn't die because Iris unleashed unimaginable power for the first time.

The enormous black hole swallowed the Beast of the End, sending itself and the Beast of the End to nothingness.

The reason she survived was not because of the immense power she unleashed, but because it piqued the interest of the Beast of the End. So, when it returned from the Void, it also brought Iris back with it.

But when Iris woke up, the scene before her was still a mess.

She protected nothing; the Beast of the End destroyed everything she had tried to protect.

The mangled corpse of the Azure Phoenix was laid out conspicuously before her.

"I really am the strongest."

When Iris arrived alone before the Beast of the End for the third time, carrying many hopes and the last wishes of the dead, she was still able to smile.

No one could advise her, and no one could comfort her.

When the end of the world comes, everyone will be doing their best just to survive.

The iris is the only sun, constantly guiding and comforting others.

A confident and powerful magical girl redeems everyone in the apocalypse.

To dispel their despair and pain.

Until the very last second before destruction, everyone was filled with hope and peace of mind.

Unfortunately, even miracles have their limits.

Even with the gravity rules activated to their fullest extent, exceeding the limits of reality, they failed to harm the Beast of the End in the slightest.

Faced with a hopeless reality, the iris that ultimately disappeared felt no pain or despair.

It was only with a final, brilliant strike that it touched the pupils of the Beast of the End.

It shook its resolve.

The Beast of the End stood beside Shion, watching with her the magical girl Iris, who, no matter how many times she was reincarnated, always faced herself with optimism and confidence, and challenged herself with powerful willpower.

Countless pairs of eyes, containing countless worlds, revealed fascination and longing.

"Don't you think it's beautiful? That posture, which transcends the so-called multi-dimensional box, can make monsters develop a spirit. No matter how many times, it fascinates me."

Shion looked at Iris, who remained unchanged as always, and nodded. "Iris is indeed very strong."

"Hehe, I knew you would understand."

……

Even from afar, inside Jiang Si's body, she could see through the Witch Shion's vision that the Emperor of the End Beast and the little black dragon were looking at each other in bewilderment.

I never expected Shion to have such a high opinion of Iris, and that seemingly complex Beast of the End also favors Iris so much…

"Could she really be the darling of the world?"

Hearing the little black dragon's sigh, the emperor shook his head. "It is her own strength that makes Ziyuan and the Beast of the End take notice. After all, the only way to make them remember is through her own strength."

Then she smiled and said, "Perhaps I can tell Iris about this later, she'll definitely be happy."

"No, no, no, I think she'll just laugh and say that I'm just naturally this strong..."

"Then let's forget about it."

"Yes, she's already very confident. If she finds out that the two strongest beings in the world acknowledge her, she'll be on cloud nine..."

The two were talking in the North Sea, a new world that Tiana had created herself.

Jiang Si's arm was severed and flew off.

"You're getting stronger and stronger, Tiana."

The Emperor and the little black dragon's attention was also drawn back from the Beast of the End. Looking at the increasingly powerful Tiana, both of them felt somewhat uneasy.

"Is this going to be okay?"

"Boss, Dad, why aren't you transforming yet?"

As the conversation between the witch Shion and the Beast of the End echoed in the void, Jiang Si and Tiana's battle had already leveled the North Sea.

Tiana went from initial tentative exploration to becoming increasingly bold, her power steadily increasing, and her body undergoing continuous transformations as she adapted to the gifts from the Beast of the End.

When she finally pushed her power to a level sufficient to crush the continent, the first real wound appeared on Jiang Si's body.

The left arm, which couldn't dodge in time, was severed at the shoulder. The blood mist gushing from the cut was ignited in the extreme cold and turned to ashes along with the severed arm.

However, Jiang Si's expression remained unchanged. He maintained his human form, and even his breathing remained steady, as if losing an arm was a trivial matter.

He leaped up and slammed his single arm down on Tiana's body!

He was still pondering how to explain the differences in power levels to the Beast of the End.
