I'm in a crossover anime world, and I've been transported to Hogwarts twice.

The wisteria blossoms outside the window were blown away by the wind, and a petal drifted onto the tea in Ubuyashiki Kagaya's teacup. The fallen petal was like a pre-written fate note, announcing that Ubuyashiki Kagaya's life would also wither away like a petal.

Kagaya Ubuyashiki gazed at the petal, a bitter feeling rising in his heart.

He knew his time was running out, but that was precisely why he needed to seize this last opportunity.

With Genichi Hanyu's reminder, Amane Ubuyashiki then noticed that her husband's cuffs were stained with small spots of scarlet blood.

A flicker of pain crossed her eyes, but she quickly regained her composure.

As a descendant of a priestly family, she understood her husband's mission better than anyone else.

"We don't need you to do that for now. As long as Muzan Kibutsuji doesn't dig his own grave, finding him won't be a problem for us."

Genichi Hanyu's words plunged Kagaya Ubuyashiki into deep thought. Kagaya Ubuyashiki understood this better than anyone else.

"Then, I wonder if there is anything you need me to do, Mr. Yuzuru?"

If Genichi Hanyu didn't come for those demons, then why did he come?

Kagaya Ubuyashiki decided to ask directly.

Time was too precious for him to waste.

"I need some of your blood for research. I'm quite interested in this genetic disease in your family. I want to know if it's a hereditary disease or a curse!"

Upon hearing Genichi Hanyu's words, Kagaya Ubuyashiki recalled his father's dying words, the swordsmen who had sacrificed their lives in the mission, and his young children. All this suffering stemmed from that initial curse.

Genichi Hanyu's words were like a sharp sword, pointing directly to the deepest wounds of the Ubuyashiki family.

Kagaya Ubuyashiki's breath caught in his throat for a moment.

The request came so suddenly, yet it made perfect sense.

He couldn't help but recall the ancient records of his clan: when Muzan Kibutsuji transformed into a demon, all the shrines in the Ubuyashiki residence simultaneously shattered, and his ancestor vomited blood and died on the spot.

For the next four hundred years, this curse clung to every man in the Ubuyashiki family like a malignant tumor.

Genichi Hanyu was quite curious about the illness that Kagaya Ubuyashiki had.

The Ubuyashiki family is an ancient family related to Muzan Kibutsuji by blood. Because Muzan fell into demonhood, they were cursed, and their male descendants are weak, sickly, and die young, with an extremely low survival rate for newborns.

To continue their bloodline, the family has intermarried with the priestly clan for generations, barely managing to keep their offspring alive until adulthood.

But whether it was a curse or something else, Yuzuru Genichi became curious.

Kagaya Ubuyashiki realized that Genichi Hanyu was not only there to eliminate Muzan Kibutsuji, but was also drawn to the mystery of the curse that had lasted for hundreds of years.

"No problem 310."

Upon hearing that Genichi Hanyu wanted to study his genetic disease, Kagaya Ubuyashiki immediately agreed.

If possible, the other party might be able to research something that can help him recover.

Although I don't have high hopes, what if it happens?

The other party even had the potion to turn a ghost into a human, and they could probably produce it. What if they could actually cure me?

Kagaya Ubuyashiki may not be afraid of death, but no one wants to die if they can live.

If he could, he would want to see Muzan Kibutsuji die with his own eyes!

This thought ignited a spark of hope in his heart.

He imagined himself standing in the sunlight, witnessing firsthand the scene of the demon that brought endless suffering to the world vanishing into nothingness.

Genichi Hanyu took a blood collection tube from his pocket, then gestured for Kagaya Ubuyashiki to extend his arm, and inserted a needle into Kagaya Ubuyashiki's vein.

After collecting the blood, Genichi Hanyu put away the test tube and was about to leave when a heavily wounded member of the Hidden Sect stumbled in, his face filled with terror: "My lord! The Twelve Demon Moons have gathered hundreds of demons and are heading this way!"

Kagaya Ubuyashiki immediately understood: Muzan Kibutsuji had sensed the threat and was about to strike first.

But how did they know about the Demon Slayer Corps' headquarters?

But this wasn't the time to think about that, and Kagaya Ubuyashiki immediately devised a countermeasure.

"Notify all Pillar-level swordsmen to immediately return to defense and prepare for battle."

Kagaya Ubuyashiki's voice was steady and powerful, not at all like that of a dying man.

78 The most cowardly final boss, with an abundance of sympathy.

"Then you guys make the arrangements, I'll go find Muzan Kibutsuji."

Genichi Hanyu's voice echoed in the tea room as his fingertips tapped rhythmically on the table.

A dangerous glint flashed in his eyes, as if he could already see the ghost king hiding in the darkness.

Genichi Hanyu knew all too well Muzan Kibutsuji's cowardly personality.

For hundreds of years, this so-called Ghost King has been like a rat hiding in a gutter, never daring to face the enemy head-on.

Whenever the Demon Slayer Corps is about to make a breakthrough, he will run away like a frightened rabbit.

Just like when I first met Yoriichi Tsugikuni.

"If we let the Twelve Demon Moons take the initiative to attack, then Muzan Kibutsuji definitely won't dare to show up. So, to prevent the enemy from hiding later, I've decided to go find them first."

Genichi Hanyu chuckled, looked at Kagaya Ubuyashiki, and then said.

Genichi Hanyu then decided to take the initiative to find Muzan Kibutsuji.

He knew that the best way to deal with such a cowardly enemy was to strike at the heart of the enemy's territory and give them no chance to escape.

Instead of waiting passively, it's better to take the initiative and catch the other party off guard.

As for the Demon Slayer Corps, Genichi Hanyu also sent people to help.

Somewhat worried, she turned to look at Kagaya Ubuyashiki, whose face was pale but whose expression remained as firm as ever.

"You all know how to use UV lamps now, right?"

"I asked Yuzuru Genichi."

Kagaya Ubuyashiki nodded: "As per your instructions, we have deployed thirty-six specially made ultraviolet lamps around headquarters. The illumination range of each lamp has been precisely calculated to ensure that no ghost can hide."

Kagaya Ubuyashiki's voice, though weak, carried an undeniable confidence.

With the presence of ultraviolet lamps, those twelve ghost moons are doomed to die.

A cold smile curled at the corner of Yuzuru Genichi's lips.

He could almost see the twelve ghost moons turning to ashes under the ultraviolet light.

After all, killing the Twelve Demon Moons should significantly increase the progress of conquering this world.

The five philanthropists have already conquered a small part of the world in just half a month.

Even so, the progress of conquering the world has only reached 10%.

This made Genichi Hanyu realize that in order to conquer the world, he still needed to deal with Muzan Kibutsuji and the Twelve Kizuki.

After all, the entire storyline revolves around Muzan Kibutsuji.

Genichi Hanyu knew very well that as long as the source of this curse existed, this world could never truly be changed.

Those who want to distort the original lines of fate and rewrite the life trajectories of others all point in the same direction: the Ghost King hiding in the darkness.

With the Twelve Demon Moons dealt with, only Muzan Kibutsuji remains.

Uh, that’s not right.

Besides Muzan Kibutsuji, there is also Tanjiro Kamado.

Genichi Hanyu's gaze became complicated.

As the protagonist of the world...

He recalled the red-haired boy's warm smile.

Genichi Hanyu did not want to kill Tanjiro Kamado unless absolutely necessary.

This is not only because Tanjiro helped Genichi Hanyu find the Blue Spider Lily, but more importantly, Genichi Hanyu admires Tanjiro Kamado's personality.

That boy possessed a purity rarely seen in this era.

Even after experiencing the tragedy of losing his family in the original story, he still maintained his enthusiasm and kindness towards strangers.

Such a person is like a dazzling pearl in this distorted world.

If possible, Genichi Hanyu wanted to subdue the other party.

Besides Tanjiro Kamado, there are also Nezuko Kamado and Zenitsu Wazuma and his group.

When Yuzuru thought of the girl biting the bamboo tube, he realized that all of them deserved a better ending.

Of course, if things really come to that point, Genichi Hanyu is capable of being ruthless.

After all, compassion can only be given when one has plenty of resources.

Genichi Hanyu sighed and then disappeared into the tea room at the Demon Slayer Corps headquarters.

Then, the vanished Genichi Hanyu reappeared in Tsurugi's laboratory.

Looking at He Xi's graceful figure, Yu Sheng Genichi showed no emotional change, only indifferently asking He Xi a question.

"Has Muzan Kibutsuji been found?"

Seeing Genichi Hanyu's expression, Tsuruhi raised an eyebrow.

Brain shut-off surgery?

He Xi knew about this magic; she had borrowed a spellbook from Yukino Yukinoshita and read it, so she immediately recognized that Genichi Hanyu was using the Occupy Central technique.

Is it because of what happened last time?

He couldn't help but feel a renewed, intense hatred for Liang Bing.

If it weren't for Liang Bing, she would have succeeded.

Then He Xi tossed something to Yu Sheng Genichi: "Here you go. Take this and I guarantee you'll find Muzan Kibutsuji. Even if Muzan Kibutsuji buried himself underground, I can still find him for you."

She tossed a strangely shaped device to Genichi Hanyu as casually as if she were throwing away an insignificant trinket.

Genichi Hanyu raised an eyebrow, holding the device that looked like a Dragon Ball radar.

This circular device is made of some kind of metal, with a small display screen in the center, making it look like a mobile phone.

"How do you use this?"

"Press the button, and then text and directions will appear."

He Xi paused for a moment and then continued, "I have already inputted the cell sample of Muzan Kibutsuji extracted from the blood of the Twelve Demon Moons into it. As long as he is still on Earth, he will not be able to escape the search of this tracker."

"Alright, I'm leaving then."

Genichi Hanyu put away the (Qian Hao Zhao) tracker and turned to leave.

"I will go with you."

He Xi suddenly said.

"I am very curious about Muzan Kibutsuji."

Her eyes shone with the inquisitive light characteristic of scientists.

"If I have the chance, I'd also like to study Muzan Kibutsuji."

Genichi Hanyu stopped in his tracks: "You really are a research fanatic, Miao."

"Don't you think this is an excellent research sample?"

He Xi's voice carried a hint of excitement.

Genichi Hanyu was silent for a moment, then finally nodded slightly.

He did not reject Tsurugi because what Tsurugi was researching was useful to Genichi Hanyu.

No matter what Muzan Kibutsuji discovers, Genichi Hanyu is the beneficiary.

"Then let's go."

He raised his hand and placed his forearm in front of He Xi, indicating that He Xi should put her arm on his arm.

The power of 79 gods

He Xi looked at Yuzuru Genichi's arm but did not put her hand on Yuzuru Genichi's arm. Instead, she pried open Yuzuru Genichi's fist that was holding the ball and then tightly grasped Yuzuru Genichi's hand with her fingers interlocked.

"Okay, we can go now."
