No, where does this portal come from?

Looking at Lin Yan's departing back, Hei Zan couldn't help but feel grateful.

"Mr. Lin...what a good man!" Thinking of this, Heinuma walked quickly towards the room.

With Lin Yan's help, Hei Nuo's pharmaceutical production progress has increased rapidly!

For three consecutive days, Heinuma did not step out of the room and devoted himself to pharmaceutical work.

The sun rises and the moon sets.

It was not until the evening of the fourth day that Kuronuma finally walked out of the room with a tired look on his face.

In his hand, he was holding half a bowl of medicine.

At this moment, the medicine in his hand had undergone some kind of processing. The original sesame paste-like texture became light and transparent, like clear water, emitting a faint blue fluorescence.

“I did it…I did it!! I did it!!” Heinuma kept muttering, “Huh – hold steady…hold steady…don’t panic…”

"Wuzan is saved! Master Wuzan! Just wait for me... I will prove that my medicine can cure all diseases in the world! Even yours!"

Kuronuma's eyes were filled with bloodshot. He forced himself to steady his hands which were trembling with excitement, and walked towards Muzan's room with steady and quick steps.

In the courtyard, the moonlight was like water, and his shadow was stretched out long, casting it on the bluestone road.

He walked under the bright and clear moonlight, like a child going to present treasures to adults.

Tread-tap-

The sound of crisp footsteps rang out in the courtyard.

Looking at the closed door of Muzan's room.

Hei Nuo took a deep breath and calmed himself down.

Place your palm lightly on the door handle and pull it gently...

squeak-

The wooden door made a slight sound.

Then, Hei Zan walked in quickly with the potion.

But as soon as he walked into the room, the smile on his face stopped abruptly.

"Mr. Lin... Lin? Why are you here? Where is Mr. Muzan?" Kuronuma asked embarrassedly.

"Wuzan?" Lin Yan raised his eyebrows slightly: "Are you looking for him?"

As he spoke, he waved his hand.

The golden light turned into a giant hand and opened the door.

At this moment, Muzan was like a piece of dried bacon, hanging on the beam, his mouth tightly stuffed with linen and tape, unable to make a sound.

"Master Muzan!" Heinuma looked at Muzan anxiously, then angrily looked at Lin Yan: "Mr. Lin! Don't you know that Master Muzan is a noble? How could you treat him like this!"

"And putting aside his noble status, Master Muzan is a patient! What you are doing is a disgrace to your dignity as a doctor!"

"The dignity of being a doctor? I think you're mistaken..." Lin Yan sneered and continued, "I never said I was a doctor."

"The identity of doctor is just your preconceived notion." As he said that, Lin Yan stood up and waved towards Hei Zan.

"Alright Kuronuma, the healing game ends here... Now, give me what you have in your hand."

When Hei Zha heard that Lin Yan wanted the potion in his hand, his heart suddenly tightened.

The steps kept retreating...

"Impossible! This is medicine prepared for Master Muzan! You can't take it..."

"Don't...don't come over here! If you come over here again, I'll throw him out!"

Tread...tread...

The heavy footsteps seemed to be stepping on Hei Zhu's heart.

Looking at Lin Yan's approaching figure, Hei Zha took a deep breath and raised the medicine high!

Seeing this, Lin Yan sighed softly and suddenly pointed his finger: "——Fixed!"

In an instant!

Golden light surged from all directions, converging towards the black swamp like glass!

In the blink of an eye, the black swamp was completely wrapped in golden glass and could not move at all.

Fixation method.

From Black Myth Wukong.

This method originated from a sudden idea that Lin Yan had a few days ago.

At that time, he used a brush dipped in gold ink to write the word "Ding" on the palm of his hand.

After discovering that the empowerment panel could really empower this word "ding" into a fixed body technique, Lin Yan spent one hundred empowerment points to empower it.

As for why it's so cheap...

Naturally, the immobilization technique he enabled was a one-time use.

If you want to have the immobilization technique all the time, you will need 3,000 empowerment points for original empowerment.

Otherwise, you can only empower it one time at a time.

"Hey...this is a hundred points...I didn't want to use it on you."

"But I'm afraid that if I attack you, the potion in your hand will spill...tsk tsk tsk tsk...what a waste." Lin Yan slowly took the potion from Hei Zan's hand.

Then a piece of text appeared before my eyes.

[After accessing the 'Enhancement Potion', you can spend 800 Energizing Points to perform Chaos Energization.]

[Strengthening Potion: A potion in the world of Demon Slayer. After drinking it, the lifespan of ordinary people will be greatly increased. They will only age naturally after ten thousand years. Their strength, speed, nerve reflexes, and recovery abilities will be significantly improved. Even if their heads are smashed, they will not die.

And after drinking it, different 'skills' will be awakened according to one's own personality and abilities.

This medicine has been perfected and has no side effects. 】

After reading the introduction of the medicine in his hand, Lin Yan nodded with satisfaction.

Then, he looked at Muzan who was hanging on the beam.

Without saying a word, the golden light transformed into a palm and crushed his neck...

[The plot of "Demon Slayer" has been significantly changed.]

[Empowerment Points +3000]

A major change? Why not a complete world change?

Lin Yan frowned slightly.

After thinking for a moment, he looked at Hei Zhan who was unable to break free from the immobilization spell.

The duration of the immobilization technique will be extended or shortened depending on the strength of the opponent.

As an ordinary person, Hei Nuo couldn't break free from the immobilization spell in a short time.

Lin Yan narrowed his eyes slightly...

Are you going to kill Black Swamp?

After spending many days together, he also had a certain understanding of Black Swamp.

Kuronuma, a doctor...a doctor who is almost crazy in order to save people.

In the plot, in order to save people, he knew that the potion had side effects, but still dared to feed the incomplete potion directly to Muzan.

If I let him go, Hei Nuo will definitely feed this potion to the patients if he encounters difficult-to-treat patients.

And he himself does not have the ability to find the complete prescription, which means he can only give others incomplete medicine, and then the world line will return to its original state...

If the Muzan in front of us dies, a new 'Muzan' will be born.

He will also be killed by the person who drinks the potion due to its bloodthirsty side effects.

So as long as Kurozuma doesn't die, there's a chance a new Ghost King will appear in the world...

Thinking of this, Lin Yan shook his head helplessly.

After all, this world line was brought about by Black Marsh.

As long as he killed Hei Zhan in advance, the subsequent events would not have happened at all.

Even if Muzan were still alive, he wouldn't be able to cause much trouble.

"It seems that I have been choosing the wrong target all along..." Lin Yan sighed and looked towards the black swamp.

"I originally just wanted to kill Muzan, but now it seems——"

"sorry!"

humming—

The teeth-grinding sound of bones breaking echoed throughout the room.

next moment!

[The world line of Demon Slayer has been completely changed! ]

[Empowerment Points +10000]

Looking at the two corpses in the room, Lin Yan's expression did not change. He picked up the potion and drank it all in one gulp.

After licking the remaining medicine from the corner of his mouth, Lin Yan leaned forward with his hands and sat down at the table beside him, quietly waiting for the changes in his body.

Time passes minute by minute.

After a long time, Lin Yan still couldn't feel any changes in his body.

"This...hasn't changed much."

Pinch left, pinch right.

Just as he was about to jump off the table, the moment his palm touched the table, he pressed a hole in the solid wood table...

At this moment, Lin Yan completely understood why Muzan wanted to kill Hei Nuo after drinking the medicine.

First, the doctor fed me black sesame paste for several years, but it had no effect at all.

When your body is failing, the doctor suddenly comes to you and says you can be saved, and then hands you a bowl of black sesame paste. But after drinking it, there is still no improvement. Who wouldn’t be anxious?

Chapter 55 Purple Entry?!

Looking down at the big hole on the table, Lin Yan fell silent.

It seems that... the physical changes caused by taking the medicine have actually occurred quietly, but I just didn't notice it.

Opening the door, Lin Yan walked out of the room into the moonlight.

At this time, under the influence of the potion, the color of his eyes had returned to its original black.

Turning to look at Muzan's room, a flash of electricity emerged from his fingertips, igniting the tatami woven with rush, and threw a can of alchemical potion into the room.

The alchemical potion exploded when it came into contact with fire, adding fuel to the small flame!

After doing all this, Lin Yan climbed over the wall and ran away.

Soon, the news of the fire in Muzan's room ignited the entire Ubuyashiki family.

Someone tried to put out the fire, but it was too late...

It was not until dawn that the flames burned through the room and died out naturally.

“Ahhhhh————”

"Muzan!!!" The shrill wail of the head of the Ubuyashiki family echoed throughout the courtyard from the firelight.

It's a pity that it doesn't help.

On the other side, Lin Yan, who had just finished all this, jumped back to the room. Getting rid of Muzan and changing the world line made him in a good mood.

Find the evil spirit that was created before.

Grip the hilt of the knife tightly.

The prompt of the empowerment panel flashed before my eyes.
