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

Besiege Wei to rescue Zhao.

Giyu Tomioka could only dodge, when a roar came from the side. Nezuko came in a rage, her hands forming claws as she attacked him.

Caught between the two, Giyu Tomioka was unable to attack any further and floated lightly backward.

Having gotten a chance to catch his breath, Tanjiro Kamado, panting heavily, quickly got up.

He was still shaken; he had almost been hit.

Although he was puzzled as to where the voice in his mind came from, he dared not be negligent in the slightest and kept his eyes fixed on Tomioka Giyuu in front of him.

The three faced off.

After a moment, Giyu Tomioka sheathed his sword and slowly spoke:

"A desperate move to survive? A very conscious strike."

"If you want revenge, you are still too weak."

"Go visit an old man named Sakonji Ryukaki who lives at the foot of Mount Sagiri. Tell him that Giyu Tomioka sent you."

Without giving Tanjiro Kamado a chance to ask a question, Giyu Tomioka turned around, but then turned his head to the side and said:

"Although there is no sunlight now, we should not let her go out once the sun comes out in the future."

As soon as the words were spoken, the other person disappeared into the vast expanse of white snow.

Tanjiro Kamado had many questions he wanted to ask, but he didn't know where to begin. Now, he was more concerned about what the voice that had just echoed in his mind was all about.

"who are you?"

he asked quietly.

no respond.

"Is it an illusion?"

Tanjiro Kamado scratched his head in confusion, but his exhaustion made him unable to hold on any longer, and he collapsed in the snow.

Looking at the gray sky, he felt as if he had been transported to another world.

"It's not your imagination."

The sound they had heard before suddenly rang out again.

Tanjiro Kamado was startled when he heard the sound again. He quickly sat up in the snow and looked around.

Who are you? Where are you?

Having just survived the battle to protect her younger sister, she then encountered an unfamiliar voice that resonated deep within her heart.

Anyone would feel confused and puzzled.

"Stop shouting, I'll live inside your body."

Why are you speaking inside my body?

Tanjiro Kamado felt even more confused. He scratched his head, completely baffled.

Nezuko, standing nearby, also looked at Tanjiro Kamado with a puzzled expression, seemingly curious about his self-talk.

"I'm just a traveler who's temporarily staying here because I saw something interesting. Like I said, I'll help you."

Lin Yu found it extremely interesting.

Just as Nezuko was about to attack Tanjiro Kamado, he had already taken control of the miniature extraterrestrial demon within Nezuko's body.

Just as he guessed, the bloodthirsty impulses were mostly released by the extraterrestrial demons.

After he took control of the extraterrestrial demon, Nezuko's bloodthirsty desires vanished instantly.

Lin Yu had expected his guess to be correct. What he found interesting was that he seemed to have discovered why Tanjiro and his sister Kamado were able to resist their bloodlust.

The secret lies in a special substance in Nezuko's blood that can directly affect extraterrestrial demons!

The extraterrestrial demon, who should have been fiercely resisting even when under control, was now listless and its release of emotional energy became intermittent.

Is it possible that human blood can affect extraterrestrial demons?

Lin Yu found it unbelievable.

In the world of fox spirits, there are indeed things that can affect extraterrestrial demons, but such items are extremely rare, and they are all related to extraterrestrial demons in some way.

Otherwise, the only option would be to use overwhelming power to directly annihilate the extraterrestrial demons.

But now, Nezuko's blood alone can reduce the activity of the extraterrestrial demons, which naturally piques his interest.

By studying this substance, Lin Yu might be able to create a drug to control the extraterrestrial demons, thereby achieving his goal of studying and dissecting them.

Of course, Lin Yu wasn't the kind of person who would take things by force. Now that Nezuko was in trouble, he was naturally willing to lend a hand to his experimental subject.

More importantly, Tanjiro Kamado is also such a being. If such a being were to train in martial arts, what kind of being would he be?

Lin Yu was very interested.

"Help me? How can you help me?"

Tanjiro Kamado asked.

"Of course, it's to help you become stronger."

Lin Yu took it for granted.

Tanjiro Kamado hesitated for a moment, then asked:

"That person just told me to go find Mr. Rin-taki Sakonji."

Lin Yu scoffed:

"Heh, in the end they are just some ways to strengthen the body. True martial arts are not just about moves."

After saying that, he controlled the half-dead extraterrestrial demon to release a large amount of emotional energy.

"Boom!"

In just a moment, a tree that required three people to encircle appeared with cracks resembling a spider web.

With a cracking sound, the tree crumbled inch by inch, turning into fragments.

The terrifying scene caused Tanjiro Kamado's mouth to involuntarily gape open, his eyes filled with shock.

Nezuko, like a startled cat, stared intently at the direction in which the large tree had shattered.

Once Tanjiro Kamado realized what was happening, he quickly comforted Nezuko:

"Nezuko, don't worry, there's no danger."

Nezuko calmed down after being comforted by Tanjiro Kamado.

Tanjiro Kamado, recovering from his initial shock, unconsciously clenched his fist.

His gaze hardened.

"I promise you, I'll do anything to make me stronger."

He thought that if he possessed the power he had just gained, not only would he be able to easily deal with that indifferent man, but also any target of his revenge.

"Wise choice."

Lin Yu nodded.

"Oh, and my sister, can she turn back into a human?"

Tanjiro Kamado quickly asked.

"Don't worry, you need to have enough power to save your sister. What you need now is to cultivate and strengthen yourself."

As soon as Lin Yu finished speaking, Tanjiro Kamado felt a dense array of words appear in his mind.

The complex content left him somewhat dizzy.

"This is a cultivation method. Once you've stabilized, you can begin cultivating according to this method."

Lin Yu said.

Tanjiro Kamado didn't rush to look at these contents, and continued to ask:

"What about Mr. Rinjiro Sakonji?"

"Go ahead, you need other people's help now."

Lin Yu said.

Training in martial arts requires a lot of food. If Tanjiro Kamado were to live alone, he would not only have to take care of Nezuko, but also have to work hard to provide these things. In that case, his strength would only increase very slowly.

"I see."

Tanjiro clenched his fists. He knew that Lin Yu definitely had the ability to help him take revenge, but he also knew that not everyone had to do something.

Lin Yu has already helped him so much; he doesn't ask for more.

"Alright, if there's anything you don't understand, just think about it in your mind. If possible, I'll appear."

After Lin Yu finished arranging everything, he said a few words and then became engrossed in the miniature extraterrestrial demon he had just captured.

At this moment, the miniature extraterrestrial demon's activity level was extremely low. Lin Yu estimated that it probably didn't have much time left to live, and now Lin Yu needed to take this opportunity to study it carefully.

"Thank you."
