Anime Crossover: I, the Shadow King, slaughter my way through DanMachi!

"That's amazing..."

Zenitsu's mouth dropped open: "That Shadow King is completely dominating Upper Moon Six!"

Inosuke excitedly brandished his twin swords: "See that! This is my future master! Hahahaha! He's the strongest!"

Tanjiro keenly noticed, "Why hasn't that Shadow Man delivered the fatal blow to the Upper Moon yet?"

"It seems like they're waiting for something?"

Indeed, Winping kept forcing Gyutaro to use his full strength, and besides, even the Hestia Sword, which was not a Nichirin Blade, could not kill the opponent.

"It seems this is your limit."

Ying Ping suddenly stopped his attack, shook his head in disappointment and said sarcastically, "That's right, after all, it's just Upper Moon Six. I even killed Upper Moon Three."

This sentence completely enraged Gyutaro: "I'm not like that guy!"

"You were just lucky; you only managed to kill Upper Moon Three because of the sunlight, but you seem quite smug about it."

"Blood Demon Art: Blood Prison!"

His body suddenly exploded, turning into a sea of ​​blood that submerged the entire street.

Countless blood scythes rose from the sea of ​​blood, forming a cage of death.

"Owner!"

Kanae exclaimed in surprise.

"Mr. Shadow!"

"Shrimp head!"

Tanjiro and the others also showed expressions of great surprise.

Faced with this overwhelming sea of ​​blood and such terrifying blood demon magic, they could hardly imagine how Ying Ping, who was in the center, could possibly survive!

"This is troublesome. Could that Shadow be dead?"

Uzui Tengen's heart sank, and he immediately intensified his offensive to restrain Daki.

In the sea of ​​blood, Ying Ping's figure was completely swallowed up.

Gyutaro's maniacal laughter echoed through the night: Hahaha! Finally! Finally, I've got you!

But the next second—

"Not bad Blood Demon Art, then I, Shadow, will fight with all my might."

"Thor. Destruction Kill. Final Form..."

"Azure silver light scatters and fades!"

A deafening thunderclap resounded, and countless dazzling bolts of lightning shot out from all directions, instantly evaporating the sea of ​​blood.

"boom!"

In just a moment, Gyutaro's body was also blasted into charcoal by the lightning pillar, becoming tattered and in a very sorry state.

Ying Ping, holding a sword in one hand, stood unharmed, his body wreathed in blue lightning like a god.

"what?!"

Gyutaro stared in horror at his mangled body: "I used every move I could, and I still couldn't win..."

At this moment, Ying Ping slowly took out the Mortal Blade from the system inventory: "This childish game is over."

At the same time, Kanae seized the moment when Daki was distracted: "Flower Breathing. Second Form. Mikage Plum?!"

The pink blade flashed in a graceful arc, striking Daki's neck simultaneously with Uzui Tengen's sonic boom slash.

"No-!"

"Brother, save me!"

Daki's head flew off.

"Karmic calamity and reincarnation!"

Ying Ping wielded the Immortal Blade, Unending Karma, and unleashed a powerful strike.

With a flash of sword light, Gyutaro's head and Daki's head fell to the ground almost simultaneously.

The two siblings' heads rolled on the ground, staring at each other, their eyes filled with resentment and regret.

"Why...did this happen...?"

"If I could eat more people and become stronger, would the outcome be different?"

Gyutaro murmured, gazing at his sister's head.

The weaker Daki couldn't even utter a word before quickly turning into black ashes and disappearing.

"Hmph, there's always a reason why someone is pitiful."

Yingping glanced coldly at the dying Gyutaro, then sheathed the Mortal Blade and turned to walk back.

[Ding! Main quest completed]

[Rewards have been distributed]

You have obtained the skills Holy Blue Blessing and Holy Blood Protection.

Tanjiro and his two friends ran over excitedly: "Mr. Shadow! You won!"

Yuzui Tengen wiped the sweat from his forehead and laughed, "As expected of Mr. Shadow, what a magnificent victory! Your strength is truly admirable."

Kanae walked to Yingping's side, sheathed her Nichirin Blade, and asked gently, "Master, what do we do next..."

"No, the battle is far from over."

"The real highlight is about to begin."

Ying Ping said calmly.

Upon hearing this, everyone present was taken aback.

Just as Tanjiro was about to ask a question, the stone slab beneath his feet suddenly transformed into a huge wooden door, which swung open with a bang!

"What is this—ah!"

Zenitsu's scream stopped abruptly, and he fell to the ground.

"Everyone, be careful!"

Yuzui Tengen shouted, but it was too late. There was nothing beneath his feet, and he had nowhere to grab leverage to dodge.

Accompanied by the faint sound of a shamisen, everyone was pulled underground.

It turns out that this underground area is connected to a huge city—the Infinite City!

Yingping calmly observed his surroundings during the fall—

The interior of the Infinite City is like a giant Rubik's Cube.

Countless Japanese buildings are interwoven in a way that defies the laws of physics, with corridors and rooms connected at incredible angles.

This is Muzan Kibutsuji's base of operations, controlled by a demon named Nakime. It is an alternate dimension where the spatial structure can be altered at will.

"As expected..."

Yingping smirked coldly: "Muzan, you finally can't sit still anymore?"

In fact, from the moment he stepped into the red-light district, he had long anticipated that this moment might come.

After killing Upper Moon Three Akaza, he naturally became a thorn in Muzan Kibutsuji's side.

The appearance of Upper Moon Six in the entertainment district is very likely a trap set by Muzan to lure them into it.

After all, Yingping's strength was too great, and Muzan already regarded him as a huge threat.

The final battle in the Infinite Castle has arrived ahead of schedule!

[Next up is the final chapter of Demon Slayer: The Infinity Castle Battle]

[Defeat all remaining Upper Moon demons and Demon King Muzan to receive the highest completion reward for this dungeon!]

"Owner!"

Kanae let out a panicked sound as she plummeted downwards.

"Don't be afraid."

Yingping adjusted his posture, suddenly accelerated in the air, and landed steadily beside her, catching her in a princess carry.

"Where...is this?"

Uzui Tengen cautiously surveyed his surroundings, his twin swords already drawn. "I sense some evil spirits..."

With the help of Yingping, Tanjiro and the other two landed one after another, their faces filled with shock and unease.

"Mr. Shadow, what's going on?"

Tanjiro asked nervously, "How did we suddenly...?"

"Of course it's Blood Demon Art."

Ying Ping explained in a deep voice: "Someone can control this space with the sound of the zither. After Muzan Kibutsuji discovered that Upper Moon Six had been defeated, he probably decided to deal with us personally."

"Wh-what!"

"Have we fallen into a trap?!"

"Is this Muzan Kibutsuji's lair!?"

Everyone exclaimed in surprise.

As soon as he finished speaking, the surrounding buildings suddenly began to violently twist and recombine.

Countless paper doors opened automatically, revealing a bottomless corridor.

"careful!"

Kanae immediately assumed a fighting stance; they were coming!

Sure enough, several figures slowly emerged from those dark doorways—

Upper Moon Five Gyokko

The Fourth Half-Tengu

Upper Moon Two Doma

And, the most ferocious of the Twelve Demon Moons—Upper Moon One, Kokushibo.

But what's even more chilling is that the one walking at the very back is an elegant man in a suit—Muzan Kibutsuji himself!

The crowd felt as if they had fallen into an ice cave. Faced with so many evil spirits, a look of despair appeared on everyone's face.

How is this played?

One Upper Moon demon alone could probably contend with all of them, not to mention that the Demon King Muzan is also here to oversee things!

"It was a truly unpleasant scene."

Muzan pointed at them condescendingly, his voice chilling, "Mere humans, yet you've managed to kill my Upper Moons one after another..."

His gaze was fixed on Ying Ping, his scarlet vertical pupils flashing with dangerous killing intent: "Especially you, Shadow, I'm very curious, just who are you?"

Ying Ping met his gaze without fear and sneered, "Just a hero who does things for fun."

"Ah, hero..."

Muzan sneered, "It doesn't matter. Today, all of you will die here."

He gently raised his hand, and all the Upper Moon demons simultaneously assumed attack stances.

The decisive battle is about to begin!
