Modifying the universe starts with Minecraft command blocks!

The Demon Slayer Corps headquarters, the Ubuyashiki residence.

At this time of day, the air should normally be filled with the shouts of swordsmen sweating profusely, or the hurried footsteps of members of the Hidden Sect.

But now, the entire massive ancient architectural complex is so quiet you could hear a pin drop, with only the soft rustling of the evening breeze through the wisteria grove.

Now, only two people remain here.

Tanjiro Kamado was sitting cross-legged by the corridor, clutching his Nichirin Blade tightly to his chest.

Beside him, Pei Qi was leaning against a pillar without any regard for his image, casually toying with a flower that emitted a faint blue glow.

"Mr. Pei Qi..." Tanjiro finally couldn't help but break the silence, his voice trembling noticeably.

"Can we... really succeed? Will Muzan really come?"

He turned his head and looked at the empty courtyard, his eyes full of doubt.

"After all, you have already killed Upper Moon Three and Upper Moon Six in succession. According to you, Muzan, the progenitor of demons, was extremely cautious, even to the point of being pathological."

"Having lost two of his top combatants, would he really risk going alone into the heart of the enemy territory?"

"Tanjiro, your understanding of 'desire' is still too shallow."

Pei Qi stopped twirling the flower in his hand. He slightly raised his head, and the moonlight shone through the blue flower in his hand, giving it a unique and alluring beauty.

"Fear can indeed make people back down, but for a creature that has survived for a thousand years and been cursed by the sun for a thousand years, this flower in front of it is no ordinary plant."

Pei Qi twirled the delicate blue flower between his fingers.

"This is the only key to his becoming the 'perfect being,' the sole motivation for his life over the past thousand years. Even if there is a sea of ​​fire ahead, he must jump in."

Tanjiro looked at the blue spider lily, a hint of bewilderment flashing in his eyes.

Who would have thought? This thing that the progenitor of demons had been searching for for ten centuries was growing on the land near his house, Kamado.

This dark humor of fate gave Tanjiro an indescribable sense of absurdity.

"If Mr. Pei hadn't taken me back and personally dug this thing out of that pile of rubble, I would never have believed that this was the legendary flower," Tanjiro said with a wry smile.

"The refresh conditions for this thing are very strict. It only opens for two or three days a year, and it has to be under specific lighting conditions," Pei Qi said nonchalantly.

In fact, by the time he brought Tanjiro back to his hometown, the flowering season had long passed.

But in Pei Qi's eyes, there's nothing that a few sets of bone powder can't solve. If there is, then just use a few more sets.

Pei Qi squatted in front of the soil, frantically tapping the ground with a handful of white powder.

Accompanied by a strange "swish" sound and the flashing of green life particles, clusters of blue flowers suddenly sprang up from the withered soil.

Pei Qi then ruthlessly burned all the remaining flower plants, leaving only this last one.

"A few days ago, I had 'Hidden' spread the word and deliberately sent a broken petal to the black market."

"That negligible amount could at most make Muzan feel the body's fervent desire for this gene deficiency, but it was not enough for him to complete the evolution."

Pei Qi's lips curled into a wicked smile, much like an old hunter fishing.

"Even if he knew it was a Demon Slayer Corps trap, even if he suspected we were going to take him down with us, he had no choice but to come. Because this was his obsession for a thousand years, and the last 'coordinate' I left him. What a coincidence..."

Pei Qi suddenly stood up straight and looked in the direction of the mansion gate.

"The guests have arrived. As hosts, we must not be impolite. Steady your breathing, Tanjiro."

Outside the gate of the Ubuyashiki mansion, a tall, slender figure slowly approached.

He wore a well-tailored suit and a bowler hat, his pale skin exuding a sickly elegance in the moonlight.

It was a face so beautiful it was repulsive, especially those bright red, saw-like vertical pupils that held a thousand years of arrogance and selfishness.

The King of Ghosts, Ghost Dance Tsuji Mukai.

With each step he took, the surrounding vegetation seemed to wither from the extreme sense of oppression.

His inner world was not as calm as it appeared.

He was furious, furious at the possible schemes of Kagaya Ubuyashiki, that dying man... and the unknown variables that were being systematically eliminated from his Upper Moon form...

But more than anything, it was due to the frantically pounding greed in my chest.

"Blue spider lily..."

Muzan took a deep breath, and he could feel the fragrance he had been searching for for a thousand years wafting in the air. It was the piece of the puzzle that could mend the final flaw in his life.

He pushed open the gate of the mansion.

At the end of that empty corridor, there was only a red-haired boy holding a Nichirin Blade and a strange man sitting on the ruins with a leisurely expression.

"...Is it just you guys?"

Muzan stopped in his tracks, his crimson pupils sweeping over Tanjiro before he let out a contemptuous sneer.

"Has Ubuyashiki fallen so low as to not even arrange for a single Pillar?"

"Does he really think that someone like you, a flawed individual whose breathing techniques are so disjointed, could possibly safeguard what I've been pursuing for a thousand years?"

He pointed at Tanjiro, his tone full of disdain.

"You're not even one ten-thousandth as good as that man named Yoriichi Tsugikuni. Your hand trembles as you hold your Nichirin Blade, what makes you think you can stand before me?"

Tanjiro didn't speak; he just stared intently at the culprit who had killed his family. His breathing became heavy and hot from excessive hatred.

If Pei Qi hadn't warned him beforehand not to disrupt the rhythm, he would have already rushed forward.

"Hey, you 'escape master'."

Pei Qi sat on the crossbeam to the side, holding the blue spider lily between two fingers, and waved it in front of Muzan.

"Look at your eyes, you're practically drooling. Is this what you wanted?"

Muzan's gaze was fixed on that blue petal. In that instant, he could hear the screams emanating from every cell in his body.

That was real, without any pretense; it was the key that allowed him to conquer the sun and become a god!

"Give it to me...." Muzan's voice became hoarse, and tentacles were vaguely about to emerge from his back.

"Well, it's kind of pitiful that you haven't achieved your wish at your age."

Pei Qi tossed it casually, and the blue spider lily drew a graceful arc in the air before gently landing on the stone slab in the center of the corridor.

As if completely unconcerned, Pei Qi casually tossed the blue spider lily in his hand down like he was giving alms to a beggar on the roadside.
