Lu Mingfei is transforming into the final boss.

She could be the world's savior or its destroyer, and the shift between these two identities hinges on a single thought.

However, Lu Mingfei will not use this Noble Phantasm. The reason is simple: if her soul and body are merged, the existence named Lu Mingfei will cease to exist. Her personality, her memories, and everything about her will be dissolved into the massive planet-sized existence of Nidhogg.

Her goal is to destroy Nidhogg in this world; she can only do this in this world.

The emperor's power may crumble before his enemies, but the divine power belonging to the throne high above the heavens is not bound by this rule.

That's a power and authority that only she can possess in this world, so she can only do it in this world.

They will disappear once they return to their original world.

She knew this so well that some things had to be done now. There was no room for delay.

This is also why she told Lu Mingze not to tease Fujimaru Ritsuka, because from the beginning she did not intend to use the emperor's power, but rather to use an external force that was not within the dragon clan system to break this awkward situation.

In a contest of physical strength, she could not possibly defeat Nidhogg; this conclusion was so clear it didn't even require thought.

That's why it's necessary to find another way, to bypass that rule with a power system that couldn't exist in the original world, and to make up for her lack of physical strength.

The problem is one that she cannot solve on her own, so she needs to introduce a concept that did not exist before to solve it. That's the principle.

This was considered cheating, but she didn't care. As long as she could win, it wasn't a fair and just competition. She couldn't accept the dissolution of her self-awareness. She didn't consider herself that noble, nor did she want the world to end.

Then this is the only way. If the original path is blocked, then we should take a detour and find another way.

Because He shared the same fate as her, He probably gave her the position and let her solve the problem herself.

Rather than offering salvation, it's better to offer the power of self-redemption; perhaps that's what He thought too.

Although they belong to the same category of beings, Lu Mingfei did not know what He was thinking, so these were merely her guesses.

After sinking into the pseudo-underworld, only her constantly awakening divinity and ever-expanding horizons changed her view of the world and promoted her self-transcendence.

The innocent lamb, the suffering, original sin beside them, the choice at the crossroads.

She also possesses these qualities.

Everything mixed within Lu Mingfei shapes her existence; she is a god, a child of man, and a beast that brings destruction to the world.

"Because it's meaningless and we won't use it, you don't need to know what that treasure means," Lu Mingfei said calmly.

Fujimaru Ritsuka and Mashu nodded. They had already noticed Lu Mingfei's aversion to that Noble Phantasm, so they wouldn't ask any more questions.

"We're still 60 kilometers from our destination, and we expect to arrive within a minute." Lu Mingze nimbly steered the conversation in, and just as easily steered it away from the topic.

Since her sister doesn't want to talk about it, she won't say it. How can she know her sister will hate it if she doesn't say anything? That's her logic. Of course, she's also aware of Lu Mingfei's sensitive spots, so she may seem outspoken, but she won't touch her sister's sore spot.

It's one thing to make her angry, but the most important thing is that she doesn't want to be disliked by her sister—it's that simple.

The powerful airflow repelled all invading enemies, tearing any dragon-blooded creatures that collided with it to shreds.

The blood, as strong as acid, was split in the airflow field, splashed onto the ground, and eroded the perpetually frozen Arctic ice cap.

The density of dragon blood organisms has reached the level of a swarm of ants.

They longed to embrace Lu Mingfei, to gain her soul's approval, and to become lives that would not be rejected.

Ritsuka hid behind Mashu's shield and was carried by Lu Mingfei out of the 'storm' made of monsters. After silently counting to sixty, they arrived at the center of the 'storm'.

Just as typhoons and storms have an eye, these monsters also create storms with an eye.

"That's!!!" Fujimaru Ritsuka pointed to the enormous body hidden under the ice cap. "That's... Mingfei's original body... Ouch, my head hurts."

As she gazed at that body, her head suddenly began to ache, as if she had been subjected to a mental attack.

Nidhogg, the ruler of the world and emperor of the old world.

While not as visually stunning as Tiamat, its threat level is far greater than that of the goddess Tiamat.

Spreading its wings would block out the sky and plunge the world into darkness.

Lu Mingfei secretly added a blessing to Fujimaru Ritsuka.

"That's the fifth element, which in my original world is the element of spirit. Attacks on the spirit, as it stands, are being released indiscriminately onto the surrounding area."

It made no difference to her; between kings there was no need for power, only a struggle between strength.

"So what exactly do we do?"

Mash held up her shield, watching Nidhogg's location warily. She was ready to activate her Noble Phantasm at any moment, even if it meant her own disappearance, to protect her senior.

"Let me do it."

"Conceptual Armament".

Using this concept, Lu Mingfei extended and enlarged the two swords in his hands.

A phantom appeared behind her. It resembled the mythical figure of the Heaven and Earth, a gigantic version of her, wielding a massive weapon and slashing at the ground.

The massive alchemical katana slashed down in a kasaya-slash style, tearing through the ice sheet and shredding and vaporizing all the dragon-blooded creatures in its path, turning them all into nourishment for this land.

The sword clashed with the enormous body, unleashing an astonishing surge of power that blew everything around it away, leaving only the shattered black dragon standing there.

Anger, disgust, rejection—Nidhogg is incapable of any of these emotions. It has no intelligence, possessing only the physical instinct for survival and a reaction to intruders.

Roar! ...

That was the roar of the world's greatest monster, the howl of a planetary life form, echoing across the heavens and the earth, and throughout this blue planet, the third planet of the solar system.

No matter where you are in the world, you can personally experience this devastating sound, which shakes your soul and shatters your will.

Being grumpy in the morning is not a good thing.

Lu Mingze immediately raised his hand and ordered another sword to strike. The speed of the strike exceeded the human eye's ability to capture and perceive, leaving only a faint echo that was difficult for the human ear to clearly discern.

boom!!!

This slash severed the sea surface, revealing the rocky seabed, a sight reminiscent of the miraculous opening of the sea in ancient texts, yet it failed to sever the shattered black dragon.

The black dragon had already spread its wings. Although it was three thousand meters long, it could move at a speed beyond human comprehension. Every move it made could tear apart sound, distort the wind, and disrupt the flow of magic.

"It's going to fly!!"

Mashu shouted at the top of her lungs.
