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

The demons had all seen Muzan Kibutsuji in person, so they knew what he looked like. However, the one who was so powerful in front of them that they could not defeat him was now being held in mid-air like an infant, unable to move.

At this moment, the blood in their bodies was boiling, telling them that they had to go forward to save Muzan Kibutsuji, otherwise Muzan Kibutsuji's death would surely lead to their own.

However, the terrifying wires in the air made their bodies tremble uncontrollably, and they didn't even dare to look directly at that being.

The Pillar-level swordsmen and Demon Slayer Corps members stared in shock at the towering figure before them.

"What kind of aura is this?"

Sorrowful Island was in tears. Although he couldn't see, his other four senses, which had become more acute because of it, told him how powerful the being before him was.

Even faced with such an aura, his incredibly resilient heart couldn't help but relax a little.

"What kind of being is this? Is he a god?"

Shinazugawa Sanemi opened his eyes slightly, revealing a blank look as he stared at Lin Yu in disbelief.

The other Pillar-level swordsmen and Demon Slayer Corps members were all shocked.

When Kurihana Kanao saw Lin Yu, she was shocked, but she also came to understand some things.

Perhaps it was intuition, but she vaguely felt that the god-like man in front of her was related to Tanjiro Kamado.

Then, recalling that Tanjiro Kamado had previously vaguely mentioned that he had another master.

Perhaps Tanjiro Kamado was referring to Lin Yu, who was standing right in front of him.

The only person capable of training someone as powerful as Tanjiro Kamado is someone even stronger than him.

She had been wondering why the other party hadn't taken action against the demons, but now it seemed that the other party had been planning this all along, and that closing in now was just a way to take down Muzan Kibutsuji in one fell swoop.

"So that's it..."

Chestnut blossoms fell, and Naoko stared blankly.

Meanwhile, a similar scene was unfolding at the Ubuyashiki residence.

"My lord, who is this person?"

Urokodaki Sakon was hit once, and his aura was somewhat weakened, but his eyes were brighter than ever before.

"This adult is Tanjiro Kamado's master."

Kagaya Ubuyashiki spoke up, saying that Lin Yu was now completely exposed to everyone, so there was no need to hide him anymore.

At this moment, Urokodaki Sakonji suddenly realized.

While I was surprised, I also felt that it made sense.

Tanjiro Kamado's progress was so rapid; in just a few years, he had grown to his current level, which was unimaginable to him.

During the two years he taught Tanjiro Kamado, he didn't actually play a very big role; his biggest role was probably teaching Tanjiro swordsmanship.

However, Tanjiro Kamado's progress was heading in a direction that he couldn't understand from the very beginning.

He pondered for a long time without finding a clue, and in the end, he could only attribute the reason to Tanjiro Kamado's talent.

Looking back now, I realize how shallow I was. After all, how could someone create a technique that could significantly enhance the strength of everyone while progressing at such a rapid pace?

It now seems that Lin Yu was the one guiding Tanjiro Kamado all along.

However, this is also extremely terrifying. A person's strength may only be their own strength, but if they can teach other powerful beings, it will definitely have a huge impact on the world.

However, these things have nothing to do with Urokodaki Sakonji.

Now that they've seen someone as powerful as Tanjiro Kamado, they know that Muzan Kibutsuji is doomed to die.

Then his long-cherished wish can be considered fulfilled.

At the same time, the feud between the two siblings, Zaomen and his sister, was also completely resolved.

Perhaps now he can finally retire?

Urokodaki Sakonji suddenly felt incredibly relaxed. Years of hatred and worries about Kamado Tanjiro, Nezuko, and Tomioka Giyu had all vanished without a trace.

All of this is thanks to Tanjiro Kamado's master.

On the other side, Tanjiro Kamado unleashed his full power, using several times stronger emotional energy, and Kokushibo and Akaza both perished under his fists.

Their bodies were crushed inch by inch by his fists. Even though the opponent regenerated quickly, Kamado Tanjiro was stronger and faster, and the speed at which he destroyed their bodies was also faster.

Within a minute, the two demons had been crushed several times by Tanjiro Kamado's fists.

Not to mention the shock that Lin Yu had intimidated the two ghosts when he revealed his aura earlier.

But he felt no joy at all; instead, he was filled with sorrow.

He looked up at the figure in the sky, a figure that seemed terrifying to others, but at this moment, it seemed extremely familiar to Tanjiro Kamado.

Although he hadn't seen Lin Yu in person many times, he was extremely familiar with the other's aura and voice.

Tanjiro Kamado knew that Lin Yu generally didn't like to show his face in public, so if he did, it must be for a reason.

He believed that Lin Yu was capable of easily defeating Muzan Kibutsuji, but now that he had displayed such great power, it meant that Lin Yu had other things he wanted to do.

leave……

These two words appeared in Tanjiro Kamado's mind.

He had a strong premonition that Lin Yu was about to leave this world.

Thinking this, Tanjiro Kamado noticed that dark clouds were gathering in the distant sky, with lightning snakes churning within them, seemingly poised to strike.

Lin Yu naturally noticed these things as well.

"Is this the world's punishment for something that shouldn't exist in this world?"

Lin Yu muttered to himself.

The world is naturally conscious; it possesses the ability to self-repair. An overly powerful being will naturally attract a grand purge.

Moreover, this world seems to harbor great resentment towards foreign species, as if they have some deep-seated hatred.

At this moment, Lin Yu suddenly remembered the dog hole through which he had entered this world.

Suddenly it dawned on me that this world might have already been invaded by something from beyond the realm, and that it might have suffered some damage, which would explain its intense hostility.

However, he estimated that the cleanup operation would take some time, since the world's system was too vast, and it would naturally take time to draw resources from other places.

"Then let's help the people here clean up the mess."

Lin Yu spoke softly, but to the others it sounded like thunderclaps, a powerful and overwhelming sound.

Upon hearing this, Muzan Kibutsuji, who had already given up struggling, became excited once again.

However, this time it was no longer Muzan Kibutsuji's own consciousness that was in control. Instead, the extraterrestrial demon, stimulated by Lin Yu and the power of the world, completely regained its consciousness. It struggled to stand up under the suppression of Lin Yu's emotional power, even though Muzan Kibutsuji's body had already begun to crumble inch by inch due to the pressure.

The amount of emotional energy surged forth several times greater than before, crashing against Lin Yu's resentful emotional energy like a tidal wave.

Lin Yu felt both pleased and guilty about the waste.

After all, the attack launched by the extraterrestrial demons proved that the opponent's stored emotional power might be far beyond his imagination. However, he felt it was a waste because the opponent had used up all the emotional power that should have belonged to him.

With the spirit that waste is shameful, Lin Yu acted without hesitation.

His emotional energy directly penetrated into Muzan Kibutsuji's body.

He originally intended to bring back Muzan Kibutsuji and the extraterrestrial demon together for research, but now it seems better for the extraterrestrial demon to die.

The power of resentment bound Muzan Kibutsuji like chains, and tiny tentacles extended from the chains, piercing into Muzan's body and then rushing towards his mind.

Extraterrestrial demons have taken root there.

The power of passion was still surging, and the extraterrestrial demons had already mobilized even more of their power to resist Lin Yu's attack.

Originally formless and intangible, this emotional force began to act strangely once its quantity reached a terrifying level.

Just as gravity can influence changes in matter once it reaches a certain level, so too can emotional force.

However, given the current level of the extraterrestrial demons, they have not reached the terrifying power of gravity.

The result was that everyone witnessed an extremely shocking scene.

The formless and intangible power of emotion took shape at this moment, hanging upside down in mid-air like a celestial river, with terrifying and boundless waters pouring towards Lin Yu.

Although Lin Yu's body had become enormous, it still appeared somewhat small under such an unusual circumstances.

How can this be?

Everyone stared in disbelief at the scene before them, feeling that it was impossible.

Lin Yu's existence was already beyond their comprehension, so how could there be someone even more powerful than Lin Yu?

Moreover, it resided within Muzan Kibutsuji.

Everyone's expression changed immediately, realizing that if Lin Yu died like this, then everyone here could be in danger.

The atmosphere instantly shifted. The humans were filled with worry, fear, and despair, while the demons became excited and agitated.

However, there was only one person in the entire audience who had complete confidence in Lin Yu, and that was undoubtedly Tanjiro Kamado.

Tanjiro Kamado scoffed at the sight of such an attack.

Amidst these complex emotions, Lin Yu made a move.

There was a hint of helplessness on his face.

After all, the more emotional energy the extraterrestrial demon consumes, the more it loses.
