From Demon Slayer, the sword is invincible

Zenitsu's face was frosty and his eyes were burning with rage. He tightly grasped the Sun Blade in his hand and exuded a powerful aura.

Suddenly, he used his Thunder Breath—with a flash of thunder, his figure moved as fast as lightning, and he rushed straight towards the red-eyed ghost.

Before the red-eyed demon could react, Zenitsu had already rushed in front of him. The lightning-like speed caught the red-eyed demon off guard. He opened his eyes wide and tried to resist Zenitsu's attack, but it was too late.

With a muffled sound, Zenitsu's Sun Blade fiercely chopped the giant arm of the red-eyed demon, and blood gushed out instantly, splashing in the air. The red-eyed demon screamed in pain, stepped back a few steps, and showed a look of astonishment on his face.

"This guy is totally different from before! Is he hiding his strength?" The red-eyed demon looked at his broken arm, feeling unbelievable. He originally thought that Zenitsu was just a weak being, but now he showed such a strong strength, which shocked and confused him.

However, the red-eyed ghost did not retreat because of the injury. On the contrary, a cruel smile appeared at the corner of his mouth.

"Hey... this is getting more and more interesting. It seems that Feng Xiaodao's junior fellow apprentice has some skills too!"

He licked his lips, his eyes flashing with greed, and he seemed to be interested in Zenitsu's performance.

Vampire magic!

The red light in the red-eyed ghost's eyes grew stronger again, and that illusory light once again made Zenitsu fall into an illusion.

"Hungry? Where am I? What am I doing? Where are all the girls......?"

Zenitsu looked confused and idiotic, looking around. Suddenly, a terrifying ghost face with red eyes appeared in front of him.

"Ghost...ah! Don't eat me, I...don't want to die yet, I want to...fall in love!!"

Zenitsu ran around in panic and suddenly bumped into the seriously injured Tanjiro.

"Ah, Tanjiro, why are you like this? Let's run away quickly, let's run together, we can't beat it...we can't beat this ghost!"

Zenitsu's scream woke up Tanjiro, and he shouted with his last bit of strength: "Zenitsu, send a signal to call for help, and don't look into the eyes of that ghost, or you will fall into an illusion."

When Zenitsu heard Tanjiro's voice, he was stunned and then regained some of his sanity.

"Ah? It turns out that the girls before were all hallucinations. What a pity!!"

At this time, the red-eyed demon noticed Zenitsu's changes and had some guesses in his mind. Zenitsu seemed to have two personalities. After more than a thousand years, Muzan had become knowledgeable and experienced, and he quickly realized the reason for Zenitsu's change.

But it then sneered: "Hmph, it's too late! You all will die here!" After that, it used the blood demon technique again, trying to completely defeat Zenitsu.

"Zenitsu-kun, don't look!" Tanjiro's reminder was completely useless.

However, Zenitsu couldn't help but look in the direction of the sound and once again lost the opportunity to send a signal.

The red-eyed demon smiled as he watched Zenitsu fall into the illusion again. In order to prevent this guy from switching his personality again, he ignored Tanjiro beside him and went straight for Zenitsu's head.

"No, Muzan, come at me. What kind of a shitty demon king is it to bully an unconscious person?!" Tanjiro shouted in despair.

He struggled to attack the red-eyed demon Muzan again.

Just as the red-eyed demon's claws were about to attack Zenitsu, a cold voice sounded again.

Type 1: Thunderbolt Flash!!

It's the same move, but there's a world of difference.

A dazzling flash of lightning suddenly appeared, as if to illuminate the entire world.

The sword light streaked across the darkness like a bright meteor, passing through the body of the red-eyed demon Muzan with endless power and majesty, and came in front of Zenitsu, shocking people.

"It's Mr. Xiaodao, that's great, he's finally saved!" Tanjiro was so excited to see the person coming that he almost shed tears. He really thought Zenitsu was dead.

Feng Xiaodao nodded to Tanjiro, then turned and waved.

Snapped! !

Zenitsu, with a silly smile on his face, was slapped by Feng Xiaodao, and a red palm mark appeared on his face instantly.

“Ah!! I’m dying… It hurts so much… It hurts so much, eh… Why is it my senior brother? Is this also an illusion? Impossible… Absolutely impossible, a terrifying senior brother who is about to kill me will never appear in my hallucinations!!”

Snapped! !

A gust of wind brought about a loud slapping sound, and the other side of Zenitsu's face instantly became swollen again.

"No, this is not an illusion. Senior Brother, I finally see you. I... I almost died... That red-eyed ghost almost killed me. Can I not take the test?"

The unrecognizable Zenitsu cried and wanted to hug Feng Xiaodao's thigh for comfort.

However, what greeted Zenitsu was not the warm care of his senior brother, but a strong thigh.

"You shameless fellow, get out of here and continue the assessment!!"

"Ah...I was wrong...Master...!"

Tanjiro just stared in amazement as Feng Xiaodao slapped Zenitsu twice and kicked him once, and then Zenitsu disappeared into the darkness.

"Mr. Xiaodao's way of educating his junior fellow apprentice is so special. Fortunately, my senior fellow apprentice is not like that!" Tanjiro said secretly, and at the same time, after he relaxed, the pain from his injury spread throughout his body.

But he still endured the pain and said to Feng Xiaodao: "Mr. Xiaodao, that red-eyed ghost is controlled by Muzan, and he is specifically here to deal with your junior brother. His eyes can cause hallucinations in people."

"Okay, I see. I understand. Leave it to me!" Feng Xiaodao nodded at Tanjiro. This guy didn't forget to remind others even though he was so injured. He was so kind that it was scary.

Feng Xiaodao turned around and looked at the red-eyed ghost who was split in half from head to toe. He was now trying hard to bring the two halves of his body back together.

"Muzan, Muzan, you are so pitiful. Like a mouse, you only dare to cowardly hide in the dark and retaliate against me in such a shameful way. It's so ridiculous!!"

Feng Xiaodao did not take any action. He could easily destroy such a ghost. It would be better to take this opportunity to humiliate Muzan.

The red-eyed ghost Muzan couldn't speak yet. His two eyes, which fell on both sides, stared at Feng Xiaodao with endless anger.

It was not until the red-eyed ghost fully recovered that he gritted his teeth and said:

"Only you humans care about these things. I only care about the results!"

"But looking at the current situation, your results don't seem to be very good!!" Feng Xiaodao said sarcastically.

The red-eyed demon didn't say anything because that was the fact. Zenitsu was no longer here, and although Tanjiro was seriously injured, he would not die.

Vampire magic!

The silent red-eyed ghost Muzan suddenly exploded, and the red light in his eyes gradually turned cold.

Wow!

There was a flash of knife light, and the red light was extinguished before it could light up.

"Our Lord Ghost King, please don't have such petty thoughts. My sword light is faster than your eyesight!!"

Looking at the red-eyed ghost whose eyes were blind and bleeding, Feng Xiaodao said jokingly.

"Feng Xiaodao, don't be complacent. You can't always protect the people you care about. I will always stay in the dark and make you feel pain as soon as I get the chance!!"

"Then I'll kill you!!"

Feng Xiaodao swung his sword again, and the body of the red-eyed demon Muzan completely dissipated and turned into ashes.
