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

Tanjiro Kamado said something in a low voice, and then, feeling it wasn't enough, he knelt down in the snow.

However, this was destined to go unanswered.

Tanjiro Kamado didn't mind. He bowed three times, then got up and pulled Nezuko to his house.

Tanjiro Kamado was so busy rescuing Nezuko that he didn't even have time to bury his own family members.

Now that Nezuko is alive and well, she naturally needs to go back to bury her loved ones.

The snow was still falling from the sky, and the snow that landed on Tanjiro Kamado's face was icy cold, making him realize that everything in front of him was absolutely real.

By the time the two returned home and buried their family members, it was already afternoon.

The snow was still falling, and the newly piled-up mounds were already covered with a layer of snow.

Looking at the mounds of earth rising in the snow, Tanjiro Kamado clenched his fists so tightly that his nails dug deep into his flesh without him even realizing it.

The happy life of the past seems so vivid in my mind, but in the blink of an eye it has turned to dust.

Tanjiro Kamado's heart was filled with sorrow.

"I will definitely take revenge."

Just then, a hand grasped his fist; it was Nezuko.

She was looking at Tanjiro Kamado with concern.

After the danger passed, Nezuko's body returned to normal.

Although her fangs and sharp nails hadn't disappeared, Nezuko's face had regained its former cuteness.

At least I still have you with me.

A warm feeling welled up in Tanjiro Kamado's heart. He gently patted Nezuko's hand and smiled softly.

Don't worry, everything will be alright.

His smile was as gentle as ever, and Nezuko's eyes also lit up with a smile when she saw it.

"Let's go, let's set off."

Holding Nezuko's hand, Tanjiro Kamado turned and walked forward.

But as he turned around, his smile vanished, replaced by a resolute expression.

He recalled the cultivation technique Lin Yu had just carefully studied, and he had vaguely understood its wonders.

Although he didn't know how long it would take for him to reach Lin Yu's level of skill, Tanjiro Kamado firmly believed that he would succeed.

He was determined to save his sister and kill the murderer!

This idea had already taken root in his mind, becoming a seed for medical aesthetics.

The power called hatred will be nurtured day and night until it grows into a towering tree.

A smile crept onto Lin Yu's lips, hidden deep within Tanjiro Kamado's heart.

A powerful surge of emotion was welling up within him, and his spirit was gradually growing stronger. (End of Chapter)

Chapter 248 Training and the First Murder

Tanjiro Kamado's journey is not easy.

Nezuko didn't want to be exposed to sunlight at all, so the two of them could only travel when the sun was setting.

Of course, these difficulties are nothing to Tanjiro Kamado.

On the contrary, the mysterious body-refining technique given to him by the mysterious person in his mind caused him a lot of trouble.

Because the various incantations contained words he didn't know and found difficult to understand, he could only cautiously ask Lin Yu for help each time.

Although Lin Yu, who seemed to have a bad temper, always helped him answer these questions, in return, Lin Yu made many more demands on him.

It was another day of traveling. Although the winter nights were long, the thick snow and low temperatures forced Tanjiro Kamado to walk for a while and listen for a while.

This is often when he listens to Lin Yu explain the body-refining technique.

Lin Yu's voice echoed in his mind for almost an hour. When he finally snapped out of his daze from Lin Yu's explanation, he noticed a ray of light in the cave he was in.

The sky outside was breaking into daylight.

Tanjiro Kamado subconsciously glanced at Nezuko beside him and immediately noticed that she was cautiously avoiding the sunlight, looking at him timidly.

"Alright, let's rest here for now and continue our journey when it gets dark."

Tanjiro Kamado smiled and patted Nezuko's head.

Nezuko nodded and curled up in the corner without moving.

"Okay, let's get started here too."

At the same time, Lin Yu's voice rang in Tanjiro Kamado's mind once again.

This immediately caused the other person's expression to freeze.

"It's been so many days, does it have to be like this every single day?"

"Of course, such cold weather only happens in winter."

Lin Yu took it for granted.

Tanjiro Kamado gritted his teeth and began to remove his upper body clothing, revealing his fairly muscular physique.

Then he walked into the snow and began to swing his arms in a measured and methodical manner.

Each punch stirred the airflow in the cold air.

This is just a very ordinary fist technique without any extraordinary effects, so it is naturally not difficult for Tanjiro Kamado.

From the moment he took off his clothes, the cold began to rob him of his body temperature.

As he felt his body temperature drop, Tanjiro Kamado's arms gradually stiffened. His heavy breathing accelerated the loss of warmth from the cold air, giving him the illusion that his lungs were being pierced.

But he couldn't help but recall what Lin Yu had said earlier:

"To ensure you can keep throwing punches in this environment, you have to be fast."

Subconsciously, Tanjiro Kamado increased the speed of his punches.

He didn't stop until he had thrown a thousand punches, panting heavily.

He was radiating heat, and sweat was constantly dripping from his skin.

Despite his exhaustion, Tanjiro Kamado didn't dare to slack off in the slightest and hurriedly ran back to the cave he had just been in.

Although strenuous exercise raises body temperature due to increased metabolism, once metabolism returns to normal, the sudden change from hot to cold will inevitably lead to catching a cold or getting sick.

After my first workout, if it weren't for the mysterious person lighting a fire in front of me, I probably would have fallen ill that day.

However, after gaining experience, Tanjiro Kamado also became more conscious of collecting firewood.

Upon entering the cave, they discovered that a fire had already been lit inside.

Nezuko, who had been hiding in one spot without moving, was now busy starting a fire.

"Oh, Nezuko, you're really capable."

Tanjiro Kamado exclaimed in surprise, then smiled and patted Nezuko's head.

After traveling for some time, he had discovered that Nezuko's personality was almost unchanged from before.

He was unable to speak, but his physical strength had increased significantly.

It seems like you've become more capable?

As he warmed himself by the fire, feeling his body gradually getting warmer, Tanjiro Kamado's thoughts began to wander.

Having traveled for so long, he had naturally passed through several villages. He had consciously inquired about ghosts and had already learned quite a bit.

Although much of this information was hearsay, without exception, ghosts were described by people as extremely ferocious monsters.

Now that Nezuko has become a demon, she hasn't changed much from before, and Tanjiro Kamado has realized that Nezuko might be quite special.

"Could it be that a mysterious person stepped in to help?"

Tanjiro Kamado guessed.

The moment that thought crossed his mind, a new voice echoed in his head:

Your guess is only half right.

Lin Yu appeared like a ghost, but Tanjiro Kamado had gradually gotten used to Lin Yu's unpredictable appearances and was not frightened at all. Instead, he quietly waited for Lin Yu to continue.

"Your sister is special. Although I intervened, I could only speed up the process of bringing your sister back to consciousness."

Lin Yu spoke frankly, and he wasn't afraid that Tanjiro Kamado would have other ideas.

Putting aside the fact that the other party had no ability to resist in his hands, just considering how many days they had spent together, Kamado Tanjiro's temperament was completely fine.

"I see, but why can't my sister still speak?"

Tanjiro Kamado didn't think about anything else; his mind was entirely focused on Nezuko.

“Mental abnormalities can be cleared, but physical changes are irreversible. You could say that your sister is now physically no different from a ghost.”

Lin Yu explained it carefully.
