Achieving the Strongest Demonic Blade from Demon Slayer! Chapter 21

Zenitsu sat up, but instead of looking directly at Tanjiro, he suddenly asked, "Tanjiro, why are you carrying a demon with you?

And what's with that strange sword?"

Tanjiro froze for a moment when he heard that, then sat up as well and smiled, about to explain.

But the words had barely reached his lips before he could say them.

The wooden box in the corner opened on its own.

Zenitsu's eyes widened in terror, and he hurriedly hid to the side. "Huh? Tanjiro, you didn't even lock the box?!"

But Tanjiro merely smiled and continued trying to explain.

From the wooden box, the shrunken Nezuko crawled out. Then, under the gazes of the two boys, she gradually grew larger.

"Zenitsu, this is my little sis—"

Before he could finish.

The timid Zenitsu, who had been acting like he was at death's door, suddenly became strangely bold. Or rather, his anger had already clouded his mind.

"You've been carrying such a cute girl around with you! How could you do this to me?! We're both in the Demon Slayer Corps, so why do you get to travel around with a girl?!

I'll kill you on behalf of the Demon Slayer Corps!"

As he spoke, he pulled his sword from the cabinet behind him.

Tanjiro was genuinely at a loss for words.

"You misunderstood. She's my younger sister, Nezuko..."

Hearing that, Zenitsu did a complete one-eighty and hurriedly tossed his sword aside.

He rushed forward with a fawning expression.

"Tanjiro..."

That single word nearly sent Tanjiro straight to the afterlife.

Meanwhile, Inosuke had long since sprawled out on the tatami, having given up on thinking altogether.

The three of them temporarily recuperated there.

At night, the three went to sleep.

Inside the sword, Lin Fan opened his personal panel.

Host: Lin Fan

Template: Ashura Maru!

Demon Power: 1300

Extracted Abilities: Eternal-grade buff Indestructible! Gold-grade ability Perception, Silver-grade ability Sharpness, Born as a Pair...

Template Abilities: Blood Cry, Devour, Healing, Nourishment, Demonification...

Unlocked Abilities: Size Manipulation (after unlocking, can freely alter own size; requires 10,000 emotion points to unlock)

Demon Curse (can inflict a Demon Curse upon hitting a target, poisoning them! Requires 10,000 emotion points to unlock!)

Aerial Control (can control the blade to fly; requires 10,000 emotion points to unlock!)

External Incarnation (can consume Demon Power to create a temporary physical clone; requires 10,000 emotion points to unlock!)

Emotion Points: 12000

Looking at those still-locked abilities, Lin Fan wanted every single one.

Unfortunately, he did not have enough emotion points, so he could only pick one. At a glance, he settled on External Incarnation.

A question arose in his mind.

"System, I can create a body with Demon Power myself, so what's the deal with this External Incarnation? Are you trying to scam ten thousand emotion points out of me?"

The moment he finished speaking.

The system immediately refuted him.

"Ding! Please do not slander the system. The system does not cheat, swindle, or deceive. The External Incarnation ability is fundamentally different from the host creating a body using Demon Power.

Though both use the same method, the difference lies in this.

The clone you create is only a clone. More accurately, it is merely a mass condensed from Demon Power, whereas External Incarnation is different. It gathers itself based on a real physical body.

It can use special abilities such as Breathing Styles. It is a body specifically made for battle and can be strengthened without limit based on Demon Power output!"

Hearing that.

Lin Fan was basically certain. "I'm buying this ability!"

[ Ding! 10,000 emotion points consumed. Congratulations, you have unlocked the ability: External Incarnation! ]

His emotion points immediately hit rock bottom again.

But he still had two thousand emotion points left. After pondering for a moment, Lin Fan finally gritted his teeth and said, "Give me two more Gold-grade draws!"

[ Ding! 2,000 emotion points consumed. Beginning Gold-grade draw!

Congratulations, you received: Better luck next time... ]

Right off the bat, Lin Fan was dumbfounded.

"These two thousand emotion points aren't about to go down the drain, are they? If I'd known—"

Before he could finish.

The system notification sounded beside his ear again.

[ Ding! Congratulations, you received the Gold-grade ability: Lightning Release: Chidori! ]

Lin Fan immediately changed his tune. "If I'd known, I would've drawn earlier..."

System: "What a hypocritical host."

"What the hell do you know?"

Lin Fan snapped back irritably. Then, all the information about Chidori surged into his mind.

After taking a look, it really was the Chidori he had seen in Naruto before. The draw even included all kinds of ways to use Chidori.

The only issue was that this move consumed quite a lot of Demon Power. Activating it once required at least one hundred Demon Power, and techniques developed from Chidori—

Such as Chidori Blade, Chidori Senbon, Sharp Senbon Spear, and so on—also consumed a tremendous amount of Demon Power.

With his current thousand-plus Demon Power, he might get drained dry after using just a few techniques...

Still, the consumption was high, but the power was absolutely sufficient.

In the world of Demon Slayer, Naruto abilities could practically crush everything.

Chapter 28: Tempering Himself

Even Muzan might not be able to withstand Chidori.

This was an epic-level power boost!

But it was not enough for him alone to become stronger. Everyone becoming stronger was what truly mattered. Now he needed to plan out how Tanjiro should grow stronger.

For the time being, it was better to first develop Dance of the Fire God.

As time passed.

The next morning.

When the first ray of sunlight shone upon the earth, Tanjiro had already begun his training for the day.

In the courtyard of the residence, Tanjiro took deep breaths to keep his Breathing Style running as he carried a massive boulder and ran through the yard.

It made Zenitsu and Inosuke's scalps tingle just watching him.

"This is bad. Tanjiro's trying way too hard," Zenitsu said with wide eyes, sitting on the corridor in front of the room with a slightly stunned expression.

But when he considered Tanjiro's strength, it also seemed perfectly reasonable.

He wanted to become stronger too, but asking him to be disciplined—

Zenitsu could only say, This humble servant truly cannot do it...

As for Inosuke beside him, his response was even simpler and more direct.

Giving up!

Meanwhile, Tanjiro kept up Total Concentration Breathing while training. Yet after only a short while, he stopped and began panting heavily.

His entire body trembled faintly without pause.

"Just trying to maintain Total Concentration Breathing a little longer feels like my lungs are about to explode. Even my ears hurt terribly."

Lin Fan, inside the sword, could only encourage him. "Pain is normal. Take deep breaths and let the air circulate all the way to your fingertips. Raise your concentration as much as possible!"

"Okay!"

Tanjiro endured the pain and continued training.

Time passed quickly like that.

By evening.

Lin Fan began trying once more to guide Tanjiro into learning Sun Breathing, but no matter what he said, the results were minimal.

Tanjiro, who still could not grasp the key to it, could only keep apologizing. "Sorry, Ashura Maru. I'm too stupid. I can never learn it."

What could Lin Fan do? He was helpless too.

"Since you can't learn it for now, focus on your Breathing Style instead. Even when you sleep at night, you have to maintain Total Concentration Breathing. I'll supervise you."

Tanjiro was rather moved by that.

"Then I'll be counting on you, Ashura Maru!"

At night.

Once Tanjiro had fallen deeply asleep, his Total Concentration Breathing unconsciously slipped out of its state.

Without hesitation, Lin Fan released black mist and condensed it into a hand, then went up and gave Tanjiro a hard slap across the face.

With a loud smack.

Simple, rough, and direct.

Tanjiro jolted upright and quickly looked around.

"What happened?"

Zenitsu and Inosuke beside him were sleeping like the dead, with no sign of waking up at all.

Lin Fan reminded him.

"Your breathing got disrupted just now. Get up and go back to sleep."

"Huh? Thanks for reminding me..." Tanjiro was completely bewildered. His own sword had slapped him across the face, and he still had to say thank you.

Was there any justice in this world?

Helpless, he could only go back to sleep, but his breathing simply would not stay steady. Before long, it became disrupted again.

Lin Fan had no choice either.

He could only release Demon Power, condense another hand, and give him another smack.

Smack!

Tanjiro sat up, wronged and helpless. Honestly, he no longer wanted to sleep. "Sorry, my breathing got messed up again just now. I've really troubled you, Ashura Maru."

"Who told you to become my sword master? It's only right," Lin Fan replied naturally.

Beside them, Zenitsu actually had his eyes tightly shut, but he had already woken up and did not dare say a word.

No one would believe him even if he said it.

He woke up in the middle of the night and suddenly saw a sword slapping Tanjiro across the face.

And Tanjiro was still saying thank you...
