Fox Demon: Heaven rewards diligence; I will eventually achieve divine mastery of martial arts.

However, from his perspective as a soul, the truth of this world seems quite interesting.

"The rich aura of passion makes this place truly suitable for the growth of extraterrestrial demons."

Lin Yu cast his gaze downwards.

With short, light red hair and a faint scar on his forehead, the boy seemed unable to believe what was happening amidst the swirling snow and the crimson blood staining the snow.

He walked forward step by step and saw an even more brutal scene unfold before him.

The familiar family members were now completely silent. Blood blossomed beneath their bodies, creating the most beautiful flowers, a scene both bloody and poignant in the icy snow.

"Plop," "Plop"

The boy stepped on the still-flowing blood beneath his feet, and his slow walk suddenly turned into a run.

The scene before him made Lin Yu realize that this must be where the entire anime just began.

The world of Demon Slayer tells a story of hatred.

The haters are humans, while the hated are demons with supernatural powers who feed on humans.

The scene unfolding before our eyes is a tragic one, reminiscent of the anime, where the protagonist, Tanjiro Kamado, is confronted by Muzan Kibutsuji, the leader of the demons, who comes to create new demons after Tanjiro leaves his house.

Lin Yu had naturally seen this popular anime that swept the country. He might have thought it was a bit gory in the past, but now Lin Yu's focus was not on the scene in front of him.

Rather, it was the lingering aura of passion in the air.

"Perhaps an extraterrestrial demon resides within Muzan Kibutsuji."

Lin Yu thought of the miniature demon that had crawled in through that dog hole before.

In a place like Muzan Kibutsuji, who is hated by everyone, the other party must be entangled in resentment-type emotional power. In addition, Muzan Kibutsuji has slaughtered all kinds of humans, so he must also be full of fear-type emotional power.

"However, that extraterrestrial demon seems to have entered this world later. There should be quite a few extraterrestrial demons in this world."

The time difference between Lin Yu and the miniature demon entering this world was only a few minutes. Even if there is a certain time flow difference between the world barrier and the world of the extraterrestrial demon, it should not be more than a few hundred years.

"But now that I think about it, the power level of the Demon Slayer world is still very low. The extraterrestrial demons are thriving here."

"Perhaps, it was the existence of extraterrestrial demons that created beings like ghosts. This is not the method of ordinary extraterrestrial demons, but a special method of the previously miniature demons?"

Lin Yu pondered, gradually developing a strong interest in the miniature demon.

He had seen that special extraterrestrial demon when he launched the second soul fragment earlier.

However, even if the other party possesses amazing teleportation abilities, they are still not very intelligent.

The miniature demons of today have actually used their intelligence to create such a distorted world.

Moreover, since it only changes the physical form and does not grant the humans here extraordinary powers, the ghosts can be said to possess overwhelming power in this world.

They can absorb emotional energy even more recklessly.

"However, these are just my guesses. We will only know the specifics after a thorough investigation."

"However, judging from the current situation, the extraterrestrial demon residing in Muzan Kibutsuji must have absorbed a lot of emotional power, and its current strength should be quite strong. We must find a way to accumulate power."

Lin Yu kept analyzing the current situation in his mind and had a preliminary guess.

Once you have a hypothesis, you naturally have a direction; the rest is about finding ways to verify your hypothesis.

Although he had arrived in a completely new world, Lin Yu still set clear goals.

However, it can only be said that it is ultimately the same person. In other worlds, Lin Yu also first set clear goals and then gradually strengthened himself.

Thinking of this, Lin Yu transformed into a stream of light and entered the body of the running boy.

The boy's eyes were bloodshot as he ran like a madman through his familiar yet unfamiliar home, his breath turning into a white mist that quickly dissipated.

If you listen carefully, you can even hear what the other person is muttering:

"What's wrong……"

"what happened……"

"What exactly happened here...?"

Tanjiro Kamado never imagined that his house would turn into this state after he had only spent one night outside.

He gritted his teeth, the image of what had just happened flashing through his mind—an image he couldn't bear to look at.

Suddenly, I remembered what the old man who had taken me in for the night had said yesterday:

"...In the night of this world, there dwells man-eating demons..."

Could it be?

Tanjiro Kamado shook his head fiercely. Compared to the demons he had dealt with before, his family was the most important thing now.

“Mom, Hanako, Takeo, Shigeru…”

Tanjiro Kamado found familiar figures one by one, but their bodies were already growing cold, and no matter how he called out to them, it was to no avail.

"And Nezuko and Rokuta..."

Finally, Tanjiro Kamado found the two of them in a corner.

The two huddled in a corner, Nezuko tightly protecting Rokuta with both hands.

At that moment, Tanjiro Kamado felt as if the world was about to collapse.

He reached out his hand tremblingly and stroked their bodies.

Suddenly, a look of surprise appeared on his face.

Nezuko's body temperature is still normal!

"There's still hope, if we can find a doctor..."

Without any hesitation, he quickly picked up Nezuko, carried her on his back, and walked towards the heavy snow outside the door.

The heavy snow showed no sign of stopping.

The snow on the ground was already enough to cover Tanjiro Kamado's calves.

At this moment, carrying Nezuko on his back, every step forward was incredibly difficult.

As time went on, breathing became increasingly difficult. Every time Tanjiro Kamado inhaled the cold air from outside, he felt as if his lungs were being scraped by a knife.

When even breathing became a torment, a deep sense of powerlessness and fear rose in Tanjiro Kamado's heart.

But once he felt the weight behind him, Tanjiro Kamado managed to pull through.

"There's still a very, very long way to go to reach the town at the foot of the mountain... Nezuko, hang in there..."

Tanjiro Kamado kept praying in his heart.

At this moment, Tanjiro Kamado was so focused on getting there that he didn't notice the girl's arm tremble behind him.

At the same time, a glint of surprise flashed in Lin Yu's eyes, which were already hidden in Tanjiro Kamado's mind.

He sensed a familiar scent emanating from Nezuko.

That was the scent I smelled when I was chasing the miniature extraterrestrial demon.

"I see. That extraterrestrial demon has already infiltrated Nezuko's mind."

Lin Yu found it interesting and wondered if every ghost in this world harbored an extraterrestrial demon.

However, Lin Yu felt that it was also possible that some ghosts had been implanted with seeds of love.

The ghosts' craving for flesh and blood is abnormal; it may be the effect of extraterrestrial demons.

Lin Yu was pondering when Nezuko's body began to undergo new changes. Her body was gradually becoming stronger, and her body, which had lost control of its consciousness, was recovering.

Until she suddenly raised her head and let out a howl towards the sky.

Tanjiro Kamado, who was already facing an incredibly difficult situation, finally realized that something was wrong.

Nezuko's body became much stronger, and in the struggle, the two of them fell off the steep cliff.

The thick snow sheltered Tanjiro Kamado, and he breathed a few more breaths after surviving the ordeal.

Once he recovered, he suddenly remembered something, looked up and called out, "Nezuko!"

He looked up and noticed the girl standing not far away.

He rushed over and said, "Nezuko, don't move. I'll carry you to town."

The moment he got close to Nezuko, he suddenly realized something was wrong.

Has the girl in front of me grown a little taller and stronger?

His anxiety made him ignore this feeling, but when he approached again, Nezuko looked up.

It was a hideous face, with bulging veins, bloodshot eyes, and two pairs of fangs growing from its teeth.

She lunged at Tanjiro Kamado in an instant, letting out a low growl.

Caught off guard, Tanjiro Kamado was tackled to the ground.

In the instant he fell, he realized what was happening and instinctively used the handle of the axe at his waist to gag Nezuko.

Seeing his once gentle sister now transformed into a hideous figure, Tanjiro Kamado felt as if his heart was being torn apart. At the same time, he recalled the words his grandfather had spoken the night before when he had stayed overnight with him.

"It's a ghost!"

Why did Nezuko turn into a demon?
