No, where does this portal come from?

The refined Angora Mainyu was unhappy...

Or rather, he was terrified now.

The feeling of losing control of your body bit by bit is not pleasant.

Especially after losing control, the part you lost will come back to haunt you.

It’s like your right hand suddenly becomes disobedient one day, has its own ideas and wants to strangle you.

That's how Angra Mainyu feels now.

"Ahhhhh!!!"

Angra Mainyu, who was hiding in the black mud, let out bursts of wailing.

He struggled and tried to break free.

But what awaits him is more control over his refined body.

He kept cursing Lin Yan.

Until even consciousness is refined and controlled.

It transformed into a strange dagger with delicate patterns.

The dagger has no cutting edge, only the tip is very sharp.

The pure black surface has lines like blood vessels.

It looks like some kind of text, or some kind of totem...

And at the connection between the dagger and the handle, four crystal clear eyeballs were still spinning.

[When you come into contact with the 'Evil of This World', you can spend 6,000 power points to empower it with chaos. ]

A prompt popped up from the empowerment panel that had been silent for a long time.

Without any hesitation, Lin Yan agreed instantly.

[Empowerment Points - 6000]

Along with it, six thousand empowerment points disappeared.

A white light popped out from the empowerment panel.

"Flat tone?"

[Evil of This World: Transformation (White): There is a high chance that those stabbed by this weapon will become exceptionally kind.]

"……six."

The evil of this world becomes the good of this world.

From now on, anyone who commits great evil will only need to take out this dagger, bow down and lay down his butcher knife.

Looking carefully at this adjustment, Lin Yan's expression became extremely strange.

how to say…

This time the flat tune was not as flying as imagined.

After all, kindness and evil are two extremes.

And it says above that the person who is stabbed will become 'extraordinarily' kind...

Isn't this a kind of "pollution" and "distortion"?

It just makes people's thoughts less evil...

Thinking of this, Lin Yan returned to his own courtyard.

Today, the courtyard is well-maintained by Gu Er.

Kaz and Carl were lined up and basking in the sun in the yard.

Lin Yan walked in front of Kaz.

He weighed the dagger in his hand.

Then, with a "pop" sound, it pierced into Kaz's heart.

He then completely untied Kaz.

"Hello... Hello? Kaz? Wake up!" Lin Yan patted Kaz's face.

Sadly, Kaz didn't react at all.

It seems that his consciousness has long been numb and he has lost himself in various experiments and time.

“What a shame…”

Lin Yan sighed and sealed Kaz again.

He turned to look at Carl.

Forget it.

If Kaz runs away, we can still catch him, but if he runs away, it will be a bit difficult to deal with him.

Just as Lin Yan was wondering who to use as a test subject, a message in the group instantly perked him up.

Tanjiro Kamado: Everyone! Good news! I caught Muzan!

[-Anyone want it?]

Hey! Don’t you want to eat ice and hail?

【Lin Yan: I want it, send it to me.】

It just so happens that no one is doing the experiment.

Isn't this just perfect? ​​Let's use this despicable guy Muzan to see if the so-called persuasion can influence this despicable boss.

Although Tanjiro didn't know what Lin Yan wanted Muzan to do, he still brought Muzan to Lin Yan's residence.

At this time, Tanjiro's height had grown to 1.8 meters due to the strengthening potion.

And he seems to have become addicted to cosplaying as Yuichiro Tsugakuin over the years, and he still keeps the same costume as Yuichiro Tsugakuin until now.

This also led to the fact that when Lin Yan saw Tanjiro, he thought it was Yoshiichi Tsugakuni who came.

"Tanjiro?" Lin Yan looked at Tanjiro up and down in confusion.

"Mr. Lin Yan!" Tanjiro trotted to Lin Yan with Muzan in his hand, always with a smile on his face.

"Mr. Lin Yan, what do you think of my outfit?" Tanjiro's eyes sparkled.

In front of Lin Yan, he seemed to still be the little boy he was before.

"Emm... tasteful." After holding it in for a long time, Lin Yan finally uttered these three words.

"Hehe! I think this looks good too!" Tanjiro smiled innocently, then as if he remembered something, he threw Muzan in his hand to the ground.

"Mr. Lin Yan, this is Muzan."

As he spoke, he drew the Sun Blade from his waist and cut off the light-isolating cloth that wrapped Muzan.

Under the cover of night, Muzan's expression was so panicked.

When he saw Tanjiro in this outfit, the horror in his eyes was beyond words...

"Tsugikoku Yoriichi..."

"Tsugikoku Yoriichi!! You are not dead after all! You are not dead after all!!" Muzan Kibutsuji kept roaring in his heart!

Tanjiro never introduced his name to Muzan, so Muzan always thought that Tanjiro was Yoriichi Tsugakuni.

Otherwise, why does the person in front of me look exactly like Jiguo Yuanyi!

"Tsugikoku Yoriichi...what the hell are you going to do!?"

Since Muzan himself was unable to defeat Tsugukuni Yoriichi at the beginning, he still believes that Tanjiro, who is now stronger than Tsugukuni Yoriichi, is actually Tsugukuni Yoriichi's true strength.

Immortality is one of Tsugumi Yoriichi's abilities.

"Tsugikoku Yuichi...is this how you always introduce yourself to others?" Lin Yan couldn't help but complain.

Tanjiro looked a little embarrassed when he heard this: "Emmm... I haven't introduced myself to Muzan yet."

His opinion of Muzan has always been 'nothing to say, just do it'.

Only a fool would talk for a while before starting a fight.

Tanjiro looked down at Muzan: "Ahem!"

"Muzan Kibutsuji, let me formally introduce myself..."

"Tsugikoku Yoriichi... I know your name." Muzan answered quickly.

"...I'm not Yoriichi Tsugakuni." Tanjiro tried to refute.

However, Muzan, who believed that he was Tsugakuni Yoriichi, would not believe him: "Even though so much time has passed, do you really think I will forget what you look like, Tsugakuni Yoriichi?"

As the first Demon Slayer who was almost chopped into pieces by Tsugakuni Yoriichi, it can be said that Kokushibo's impression of Tsugakuni Yoriichi is not as deep as his own.

So in response to Tanjiro's explanation, Muzan refuted it for the first time.

"I'm really not Tsugikoku Yoriichi!"

"Do you think I will believe it! Tsugikoku Yoriichi!"

"Emmm... I think it doesn't matter to him whether you are Ji Guoyuan or not." Lin Yan suddenly interrupted.

"You beast! What have you got to do here?!" Veins popped out of Muzan Kibutsuji's body and he looked at Lin Yan ferociously.

The sudden swearing made Tanjiro stunned, and even Ultron, who had just walked out of the laboratory, was stunned.

Isn't...he always been this brave?

"...You are really awesome." After holding it in for a long time, Tanjiro finally uttered these words.

In order not to bring bad luck to Lin Yan, Tanjiro said a simple goodbye and left quickly.

Before leaving, he looked at Muzan with pity.

Wuzhan, oh Wuzhan, you'd better pray that you die quickly, otherwise...tsk tsk tsk tsk.

Tanjiro clicked his tongue, shook his head, and walked away with a pout.

After coming out of the laboratory, Ultron was not in a hurry to leave. Instead, he sat down on the steps not far away, which was uncharacteristic of him.

A hint of interest actually appeared in a pair of mechanical eyes.

"Beast! Let me go!" Muzan kept shouting, but the rope recently developed by the Demon Slayer Corps to deal with demons made it impossible for him to break free.

In addition, the unknown injection that Tamayo gave him also deprived Muzan of the strength to break free or self-destruct.

Looking at Muzan who was howling continuously, Lin Yan was no longer anxious.

A thought came to my mind.

Muzan's mouth was completely sealed.

Then Lin Yan threw him into the yard.

Time passes minute by minute.

Soon, a hint of dawn appeared on the horizon.

This is a sign of the approaching sunrise.

Seeing the sky gradually brightening, Muzan began to struggle frantically, like a big catfish coming ashore.

——Squeak! !

The first ray of sunlight shines on Muzan.

As if a bucket of concentrated sulfuric acid had been poured on him, Wuzan's body began to fester wildly, and soon his bones were exposed.

For ghosts, the pain brought by sunlight is no less than that caused by sulfuric acid.

The intense pain made Wuzan twist even more happily.

Seeing that Wuzan was about to be sunburned to death, Lin Yan walked out of the pavilion and pulled him to a shady place.

Just when Wuzan thought he was saved...

Lin Yan brought Muzan, who had recovered his body, back into the sunlight.
