From Demon Slayer, the sword is invincible

"I won't kill you in one breath. I will cut you into pieces to satisfy my desire! Unless you agree to my terms!"

A young boy who looks particularly short, with a cruel smile on his face that is inconsistent with his appearance, which makes people shudder.

He stared at his opponent with cold and ruthless eyes, as if he was enjoying this life-and-death battle.

Tanjiro held a broken Nichirin sword tightly in his hand. His lungs felt like they were exploding, and every breath brought a burning pain.

However, he did not back down, but stared firmly at the numbers in the eyes of the boy opposite him, his heart filled with anxiety and uneasiness.

Tanjiro never expected that this seemingly insignificant boy was actually the most powerful demon hidden in Spider Mountain. His strength far exceeded everyone's imagination, giving people a sense of invincibility and despair.

Tanjiro took a deep breath, tightly gripped the broken sword in his hand, and swung it out with another fierce attack.

Water Breathing Type 1 - Water Surface Slash! He tried his best, hoping to hit the opponent's lower demon Lei. Even if he knew that he might not be able to defeat the opponent, he would never give up easily.

Rui looked at Tanjiro expressionlessly, his mouth slightly raised, revealing a mocking smile. He responded quickly, shooting out spider silk threads as fast as lightning. These fast-shooting spider silk threads flashed cold light under the moonlight, emitting a deadly threat.

No one dares to underestimate the power of these simple lines, because Tanjiro's Nichirin Sword was easily cut by them.

Tanjiro flexibly twisted his body to avoid the path of the thread, but he was extremely anxious in his heart, "I can't imagine that the thread controlled by this child is so hard! I'm sorry, Mr. Steel broke your sword!"

Lei waved his little hand lightly, and the shooting silk thread quickly twisted and danced in the air, then rushed towards Tanjiro again.

“No, I can’t think about these things now. Even if I can’t cut his thread, as long as I get inside the thread…” While dodging the thread, Tanjiro forced himself to calm down and think about how to defeat the enemy.

“But the closer I get to the enemy, the denser the threads become, leaving no room for my body to pass through… and it looks like the enemy hasn’t used his full strength yet, what should I do!!

If only I had the same strength as Mr. Feng Xiaodao, is this the power of the Twelve Ghost Moons? It's really terrifying, how did Mr. Xiaodao kill these ghosts in the first place? Not to mention the upper Xuan ghosts above this!"

Tanjiro's mood was very complicated at this moment. The emergency supplies given by the Demon Slayer Corps were gone. They were destroyed by the other party before they were used. Nezuko was also tied up by this guy like a dumpling.

"I must save Nezuko, even if it means I will perish together with her! Water Breathing, Land Form, Twist the Whirlpool!"

Tanjiro once again used this move to dodge the attack of the silk thread, and his look towards Rui rekindled his fighting spirit.

"As long as you give your sister to me and let her become my sister, I will let you go! Don't make unnecessary struggles?" Rui spoke again to persuade Tanjiro. This was also one of the reasons why he did not kill Tanjiro directly.

"No way, no one can separate the bond between me and Nezuko. She is my sister, a relationship that is indestructible and was born with us!"

Tanjiro roared loudly with excitement, and his breathing became disordered involuntarily.

"But you are a human and your sister is a ghost. The best ending is to let her become my sister!" Lei said what he thought was the best reason.

"I will never hand Nezuko over to someone like you!" Tanjiro's eyes widened as he stared at Rui. "I will definitely make my sister human again. This is my promise to my mother, my family, and Nezuko!!"

"Then you shall die! Blood Demon Art: Killing Eye Cage!"

There was murderous intent in Lei's words. His hands were like a roping rope, weaving a spider web that could bind the enemy in all directions, and then he pushed it against the wall.

An extremely huge net quickly expanded and pounced on Tanjiro in front of him, strangling him into pieces.

Tanjiro retreated quickly, but the spider web did not slow down. Just when he was about to despair, his father's figure and the mysterious Kagura dance flashed in his mind.

"Father, your body is so fragile, why can you still dance to the God of Fire in the cold snowy night? Father: Because breathing has its own way of breathing!"

"Mr. Xiaodao, why is Muzan afraid of our dance? Feng Xiaodao: That is a strange ability, you must not forget to practice it!"

……

Nezuko was hanging in the air, and seeing her brother about to be strangled by the spider web, she ignored the spider silk that had already cut into her flesh, and the blood vessels on her right hand bulged.

Nezuko waved her blood-stained hands vigorously and shouted, "Blood Demon Jutsu - Blood Rage!!"

The thread stained with Nezuko's blood instantly caught fire. The thread that was originally indestructible and penetrated Tanjiro's body suddenly broke. Tanjiro passed through the spider web without any injury, as if he had been reborn.

"The line... is actually on fire?" Lei's eyes widened, an unprecedented look of astonishment on his face.

At the same time, Tanjiro regained consciousness in an instant, with a determined light flashing in his eyes, like a burning flame. He knew very well that this was a great opportunity created by Nezuko for him and he must not let it go easily.

"I won't give up... This is the agreement between Nezuko and I!" Tanjiro gritted his teeth, raised the Sun Blade high, and rushed towards Rui at lightning speed.

At this moment, Tanjiro felt his body was extremely hot, and the Sun Blade he was wielding in his hand also ignited a blazing flame.

However, he did not know why this happened, but deep down in his heart he wanted to stab the broken blade in his hand deeply into the neck of the boy opposite him.

"Shit, it's too late to attack now!" Looking at Tanjiro who was attacking him, alarm bells rang in his heart. Although his blood demon magic thread was powerful, it required time and distance to release.

At this moment, Tanjiro's sword was already in front of him, and he could only move his body forcefully to avoid the knife that was heading towards his neck.

"Fortunately, my body is harder than silk thread, and I can't be hurt even if it hits me! I have seen through this guy's strength!" Lei comforted himself in his heart.

When Tanjiro's flaming blade slashed across Rui's neck, an extremely intense burning sensation instantly stimulated Rui's brain.

"How is that possible?" The pupils in his tired eyes dilated.

Tanjiro's final powerful attack finally hurt Rui.

But at this moment, Tanjiro was not excited at all, instead tears were dripping on the ground.

"What a pity that your knife is a little short! Otherwise you would have really killed me!" Lei's neck had been chopped off in half at this time, and the wound was like a burn, with no signs of recovery.

Rui looked at Tanjiro, and the threads in his hands gathered together again.

Just then, a black cat suddenly appeared between Rui and Tanjiro.

"Okay, we can end the fight now!"

A relaxed voice came, awakening the tearful Tanjiro.

Of course there is also a dazzling knife light!!
