Demon Slayer: My breathing technique went awry after Nezuko pushed me down.

A flicker of realization crossed Shirakawa Yu's eyes. "I understand. Is this what you're relying on?"

Muzan stared intently at Shirakawa Yu, "From this moment on, as long as I am alive, nothing can get close to me if I so choose."

Shirakawa Yu stepped forward and tentatively reached out his hand.

Before even reaching within three meters, the aftershocks alone caused my palm to ache.

He could feel that the bones and muscles inside his palm had been shaken apart within those one or two seconds.

Muzan's shockwaves are now reduced in power and range.

But the frequency has increased to tens or hundreds of times per second.

If you really try to force your way in, you'll probably be pulverized in a few seconds and bounced back out.

"Very strong, very insightful." Shirakawa Yu nodded.

"So," Muzan stared at him, "can we pick up where we left off and start talking again?"

Shirakawa Yu shook his head. "You are very strong. But even you, how long can you maintain that level?"

"Half a day? Or a whole day? Or do you think you can release yourself for a whole week straight?"

Muzan's lips twitched slightly. "So what if it's only for an hour?"

"When I can't keep going anymore, when I'm completely exhausted, I will self-destruct immediately."

He narrowed his eyes and stared coldly at Bai Chuanyu.

"By then, will you wait for me to heal myself for months, or will you throw me into the pool of blood to continue this endless cycle?"

When Muzan said this much, Shirakawa Yu truly fell silent.

If what he said is true, then the most deadly thing is not this terrible shockwave, but rather the impeccable cell-level self-destruction.

Shirakawa Yu definitely wasn't willing to wait.

The same problem occurs when you throw yourself into the blood pool...

He had been observing for a while.

Muzan's self-healing didn't develop little by little, but rather grew out gradually.

Instead, when those cells that cannot be captured absorb enough energy, they attract each other and reassemble.

All you need to do is piece together a small part, or even half a head, or a heart.

Muzan can regenerate in a second or two.

Then... he will regain consciousness.

Then... he can continue to self-destruct.

In other words, Shirakawa Yu only had a brief moment of one or two seconds.

A second or two...

With such a short vacuum period, even if Shirakawa Yu used a water pump, how much of Muzan's essence blood could he extract?

He frowned, unusually...

I have a bit of a headache.

Chapter 343 The first wife is still the most reliable!

Inside the Colosseum, the air seemed to freeze.

"Then let me give it a try."

Sanemi jumped out with red eyes.

Without a word, they drew their swords and charged.

"Wind Breathing - Fourth Form!"

He moved from top to bottom, while the knife was raised from bottom to top.

Five sharp cyan wind blades, carrying rubble and dust, pressed towards Muzan's direction.

"—Rise into the sandstorm!"

Sanemi, wielding a long sword that was wrapped in wind blades, crashed fiercely into the distorted air.

In the first instant, the cyan wind blade vanished without a trace the moment it approached the edge of the shockwave.

In the next instant, Sanemi's two arms felt as if they were being scraped by countless invisible steel blades at the same time.

Layer upon layer of skin and flesh were torn apart, bones were crushed, and both arms instantly turned into a mist of blood that sprayed out.

In the final moment, his longsword was bounced back like a cannonball the instant his hands were rendered useless.

The blade spun and flew out, instantly embedding itself in the stone wall of the arena, with only half of the hilt sticking out.

From beginning to end, it only took the blink of an eye.

Muzan is fine, but Sanemi has lost both arms and half of his face.

He didn't even turn his head, not bothering to glance at Sanemi.

Bai Chuanyu stood a few steps away, arms crossed, shaking his head.

"Someone who could easily defeat you in a one-on-one situation is now going all out on defense... you really can't break through their defense."

Sanemi grinned, stood up, and his right arm emerged from the severed wound with a hiss.

But he did not restore his left arm, nor did he repair the skin and flesh that had been scraped off his cheek, leaving it bleeding profusely.

Blood flowed rapidly along the lines on the skin, making a rushing sound like a gushing stream.

He turned around, walked to the stone wall, gripped the hilt of the knife with one hand, and pulled it out.

Above, there are fine cracks visible to the naked eye.

But he didn't care; instead, he grinned maliciously.

"I just want to try. At least... I want to cut him once."

Shirakawa Yu shook his head and didn't say anything.

Sanemi then looked up and shouted towards Tanjiro in the stands, "Cover Nezuko's eyes."

Tanjiro felt helpless upon hearing this, but he knew what Sanemi would do next, so he obediently did as he was told and put his hand in front of Nezuko's eyes.

The next second, Sanemi's head fell off...

He was chopped off by his own knife.

Blood gushed from his neck, but instead of dripping, it was absorbed by the skin's texture.

His skin had turned from pale to dark red, and steam was rising from his body as if he were boiling.

After placing his head in a position where he could see Muzan, he wasn't finished. He raised his right hand and chopped off the left half of his body.

At this moment, all he could move were his two legs, half his body, and one arm.

But at the same time... the speed at which the blood flowed through the grooves of his body had undergone a complete transformation.

The babbling brook transformed into a thunderous waterfall.

The overwhelming stench of blood and the oppressive atmosphere filled the entire Colosseum.

In the past, when Shirakawa Yu learned about Sanemi's fighting style, he would laugh at him and say, "Are you cosplaying Xing Tian?"

Now, when he saw Sanemi in this form, he couldn't even laugh anymore.

If I'm not mistaken, at this moment, Sanemi's strength, speed, explosiveness... may even have surpassed his peak performance.

In the surrounding stands, those who knew him before and those who didn't all stared wide-eyed.

This is... Sanemi!?

Muzan also sensed that something was wrong.

He could also sense something was amiss behind him.

But the instant he turned around, there was no roar, no sound, only a shattered ground and a... sonic boom!

The red shadow crashed straight into his shockwave field, as if it had been forcibly embedded into it.

At this moment, Muzan finally saw Sanemi's appearance clearly.

He stood frozen, knife in hand, less than a meter away from Muzan.

His skin began to separate, his flesh began to melt, and gradually the stark white bone fragments were revealed.

but!

His knife was still slashing downwards.

Look down inch by inch.

Cold sweat beaded on Muzan's forehead.

He stared at the terrifying creature before him, its body reduced to half a skeleton, and at the knife drawing ever closer to his face. His throat tightened, and he swallowed involuntarily.

Unfortunately, even so, Sanemi still failed to achieve it.

This time, it wasn't his body that broke down first, but the longsword in his hand that already had cracks.

The knife broke.

The cracked blade shattered into metal fragments just before it touched Muzan's forehead, scattering backward and embedding itself into Sanemi's mangled body.

The fragments pierced through his remaining skeleton and flesh, like a rain of steel needles tearing apart his already broken body.

Sanemi, who was barely holding on with his Blood Demon Art, finally couldn't withstand the onslaught of countless fragments of his own longsword.

In an instant, he lost the strength to continue.

But he wasn't thrown away; instead, within the range of the shockwave, he was pounded into a bloody mist by wave after wave, thousands of shockwaves, and sprayed outwards.

Nothing was left.

This horrific scene caused many people around to frown.

Mitsuri and Zenitsu were so frightened that they immediately closed their eyes.
