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

"But they are the Demon Slayer Corps. They have been fighting demons for so many years, and it is difficult to change their beliefs."

Tanjiro Kamado ultimately couldn't let his resentment erupt; it was as if he was explaining to others, or perhaps speaking to himself.

"These are all excuses. I'm asking what your truest thoughts are, not what others say."

Lin Yu sneered.

"You think others have their own difficulties, but those are their difficulties. Why should your sister Nezuko suffer because of other people's difficulties?"

Lin Yu didn't stop; he continued:

"You should know best what you want in your heart. I taught you techniques and martial arts, and this is how you use the power I taught you?"

"Do you really think that just because Giyu Tomioka and Sakonji Urokodaki made a promise, the Demon Slayer Corps won't do anything to your sister? The power of judgment is in their hands. All you can do is hand your sister over and wait for them to decide in their own way whether your sister is the special demon."

What do you think this represents?

Lin Yu's tone gradually became more forceful from the beginning, each word like a heavy hammer hitting Kamado Tanjiro's heart, causing Kamado Tanjiro's body to tremble.

He's not stupid; he naturally knows what that means.

Once he has the power of judgment, Nezuko's life is in the hands of others, and no matter what efforts he makes, he cannot change the fact that Nezuko's life is in the hands of others.

He clenched his fists, his body seething with resentment.

"You should know this feeling clearly. You had this feeling when you faced Giyu Tomioka. Even though your sister is special, why won't Giyu Tomioka believe her easily? These people are the same. Do you want to experience this feeling again?"

Lin Yu's voice came when Tanjiro Kamado was at his most wavering, adding fuel to the fire in Tanjiro Kamado's heart.

Tanjiro Kamado bit his lip so hard that he didn't even realize his nails were digging into his own fingers.

He practically forced a few words out of his throat:

"I do not want."

"So how did you manage to get Giyuu Tomioka to change his mind? Do you still remember?"

Lin Yu's words seemed to come from the heavens, just like when they first met.

Tanjiro Kamado felt as if he had returned to that snowy day. He was already in despair because of the deaths of his mother, younger brother, and younger sister, and now his sister was about to be executed by a complete stranger. All the anger he felt at that time surged into his heart.

What did he do at that moment?

Scenes flashed through his mind, and he opened his lips and whispered:

"It's a battle, and I've chosen to fight."

"So, you can just keep doing this for now."

Lin Yu said:

"I've been keeping you training non-stop so that you'll have the power to protect Nezuko at this moment, right? So don't let your own preconceived notions hold you back. Let your emotions run wild and use your current strength to show them that they no longer have the power to decide Nezuko's life or death."

The resentment finally erupted in Tanjiro Kamado's heart, and his face became calm as water, and his eyes became extremely firm.

Yes, from the very beginning, he followed Lin Yu for training not only for revenge, but also to heal Nezuko.

If anyone tries to stop him from healing Nezuko, he will not hesitate to draw his sword against them, no matter who the opponent is!

He now possesses that power!

Tanjiro Kamado made up his mind.

Lin Yu, meanwhile, was observing Tanjiro Kamado's soul from the depths of his mind.

The soul's abdomen was originally rooted in the Tree of Emotional Power of Hatred. Now, from the roots of the Tree of Emotional Power, another separate trunk has extended out. The trunk is a faint red color, and there seems to be a substance flowing through it like quicksand.

And those substances are precisely the power of anger.

Not all of this emotional energy flowed into Tanjiro Kamado's body; most of it flowed into Rin Yu.

A cold smile appeared on Lin Yu's lips.

He has absolutely no interest in keeping the original plot.

Tanjiro Kamado came to Sakonji Urokodaki solely to focus on his training.

Now that his training is complete, if it weren't for Tanjiro Kamado's gratitude towards the Demon Slayer Corps and his refusal to leave, he would have already let Tanjiro Kamado start a massacre.

Although Mount Fuji gave him an unexpected surprise that made him feel slightly more favorably toward the Demon Slayer Corps, this did not mean that the Demon Slayer Corps had the right to judge his disciple.

No one among his disciples could be judged except him.

If the conflict is intense, he does not recommend going to the Demon Slayer Corps headquarters.

His emotional energy has now reached an astonishing level.

……

The cawing of crows echoed across Mount Sagiri, a rare occurrence, as Mount Sagiri is perpetually shrouded in mist, making it a place birds are reluctant to roost.

Tanjiro Kamado has been meditating in his room for the past few days to adjust his mental state.

Ever since that day ended, he had inexplicably felt restless. Fortunately, Lin Yu gave him a set of meditation techniques that helped him calm his mind and focus his spirit.

It must be said that this meditation posture is very relaxing. Tanjiro Kamado felt that his senses had become clearer, but as his mood calmed down, the determination in Tanjiro Kamado's heart never wavered in the slightest.

After hearing the cawing of crows today, Tanjiro Kamado seemed to sense something and went outside.

At that moment, two black dots could be seen gradually growing larger on the horizon.

As they got closer, it became clear that they were two people who looked somewhat unusual.

It was a couple, a man and a woman.

The woman's face was calm, with a faint smile on her face. Her hair was tied up with a butterfly hair ornament, and she wore a butterfly haori over her Demon Slayer Corps uniform.

The man was wearing an ugly mask, carrying a huge basket on his back, and had a rather burly build.

Tanjiro Kamado's expression turned serious. He realized that the one in front of him must be the swordsmith, and the other was Shinobu Kocho, whom Giyu Tomioka had mentioned.

Just then, the cawing of crows rang out again in the sky.

Tanjiro Kamado looked up and noticed a crow descending from the sky, flying straight towards him, and finally landing on his shoulder.

After lingering for a while, the crow rested its head on Tanjiro Kamado for a moment, as if confirming something.

Once Tanjiro Kamado's identity was confirmed, the crow immediately spoke in human language:

"Tanjiro Kamado, new mission: follow the Insect Hashira, Shinobu Kocho, to the wilderness! Head west, head west!"

Tanjiro Kamado looked at the crow with some curiosity.

After all, he had seen talking birds before, but he had never seen a talking crow.

At this moment, the two people in the distance finally arrived in front of the room.

"My name is Shinobu Kocho, and I'm the Insect Pillar."

The woman wearing a butterfly hair ornament introduced herself, while pointing to the swordsmith beside her:

"This is your swordsmith. His name is Hotaru Haganezuka, but he doesn't seem to like talking much."

The burly man wearing the ugly mask stared intently at Tanjiro Kamado.

Kamado Tanjiro felt a little uncomfortable watching this. After bowing slightly, he invited the two of them to sit inside.

After all, the two of them had traveled a long way to get here, so they couldn't just stand outside and talk.

The three entered the room, and Shinobu Kocho couldn't help but exclaim upon seeing its simple interior:

"As expected of Mr. Urokodaki, it seems he has always maintained this style over the years."

"Miss Shinobu Kocho, do you know Mr. Urokodaki?"

Tanjiro Kamado asked curiously.

Although Urokodaki Sakonji is a water pillar, humans generally experience a decline in vitality around their forties. Urokodaki Sakonji is already nearly sixty years old and has been living in seclusion in Mount Sagiri, guiding so many people. He should rarely be on missions.

"After all, he was the previous Water Pillar, so I had heard of him, and for some reason, I had visited Mr. Urokodaki before."

Shinobu Kocho continued, "..."

"You don't need to be so polite. Just tell me to be patient, and I'll be taking care of you for a while."

"Miss Ren... hello."

Tanjiro Kamado wasn't good at hiding his thoughts. After all, he was just a boy, and when he thought about what he might have to do in the future, he didn't seem very enthusiastic.

"Hello, Mr. Hotaru Haganezuka."

Hotaru Haganezuka continued to stare intently at Tanjiro Kamado, making Tanjiro Kamado somewhat uncomfortable.

After a period of silence, Tanjiro Kamado couldn't stand it anymore and left under the pretext of pouring tea. When he returned, he found that Sakonji Urokodaki had also returned.

He was talking to Shinobu Kocho, who had a polite smile on her face. Tanjiro Kamado could hear them clearly; they were talking about Giyu Tomioka.

As Giyu Tomioka wrote in his letter, Shinobu Kocho seemed to be quite familiar with Giyu Tomioka.

He often talked about Giyu Tomioka's recent situation.

Tanjiro Kamado served tea to everyone.

He had just put down his teacup when he noticed Hotaru Haganezuka staring at him again.

At that moment, he produced a Nichirin Blade and handed it to Tanjiro Kamado.

"Does this mean it's for me?"
