Modifying the universe starts with Minecraft command blocks!

The train sped through the dark wilderness, the roar of the steam locomotive swallowed by the thick night, leaving only the dull and regular clanging of the rail joints.

Inside the train, as Lower Moon One: Nightmare's Blood Demon Art deepened, the entire carriage was enveloped in an eerie atmosphere.

The reflection in the car window was no longer of the fields outside, but of the passengers' sleeping faces, which looked exceptionally peaceful and even somewhat distorted as they were deep in their dreams.

In the shadows of the middle of the carriage, a deformed, grayish-purple lower-ranking ghost silently emerged from the shadows.

Its cloudy eyes gleamed with a greedy light, and glistening saliva clung to the corner of its mouth.

Its target is a rosy-cheeked boy sitting by the window. In the dream, the boy may be reuniting with his family, but in reality, he is exposing his vulnerable neck to the monster's claws without any defense.

The ghost stretched out its slender, withered fingers, the tips of its nails gleaming coldly under the kerosene lamp, and touched the boy's throat. The pressure even squeezed out faint white marks on the boy's skin.

It could even hear the alluring sound of blood flowing beneath the boy's skin, the nourishment it needed for evolution.

Just as the sharp blade was about to slice through the flesh...

A figure dressed in a blue-purple shirt with a cold expression appeared instantly above the ghost's head, like a static model forcibly inserted by the system.

There was no shaking due to inertia, nor was there a sound of it hitting the ground.

"Bang!!"

A dull, almost metallic explosion resounded.

Pei Qi landed precisely on the back of the ghost's head at an absolutely vertical angle.

That's due to the extreme impact brought about by the "jump boost" and "speed".

The moment the ghost's head touched Pei Qi, its normally hard skull became as fragile as rotten wood.

Excuse me, could you please let me pass?

Pei Qi's voice was calm, but it sounded particularly jarring in the deathly silent carriage filled with dreamlike murmurs.

With the enhancement of "Power II" and various stealth abilities, the power of this kick was beyond logic.

The ghost couldn't even scream before its head was crushed into the train's floorboards with a dull thud as the wooden planks shattered.

Amidst the flying sawdust, the ghost's body convulsed violently, its limbs clawing helplessly in the air.

It tried to struggle, but found that the force pressing down on its head was so heavy it was illogical, pinning it firmly to the spot.

"I'll speak, you answer. Although I roughly know what's going on."

Pei Qi lowered his head slightly, looking down at the monster beneath his feet.

There was no pity in his eyes; instead, it was as if he were scrutinizing a "monster spawner" with an extremely low drop rate.

"You... what are you...?" the ghost roared in a muffled, terrified voice from the cracks in the broken floorboards.

It could vaguely sense that the other party did not have the breathing patterns of a "demon hunter," nor did it have the human aura it was familiar with.

Pei Qi sneered and made a thought.

The moment he swung his arms, a faint purple light burst from his fingertips and quickly spread throughout his body.

The ordinary blue-purple shirt was covered by a layer of jet-black, deep armor with a cold metallic sheen in a fraction of a second.

Each piece of armor is adorned with pale purple enchanted patterns, pulsating rhythmically as if it were breathing.

That's Nether Armor, the ultimate armor obtainable in the original Minecraft.

This "clothing change" process appears almost like a visual illusion to onlookers, so fast that it surpasses human perception and leaves no afterimage.

"As expected, since it's the Infinite Train, then you're just one of the small fry that Nightmare has planted."

Pei Qi's voice came from behind the fully covered alloy helmet, sounding somewhat muffled and extremely intimidating due to the resonance of the metal cavity.

"You actually know about Lord Nightmare! Since you do, then obediently die—!"

Driven by extreme fear, the ghost finally unleashed its final ferocity, its body swelling violently as it attempted to self-destruct or perish together with others. But before the ghost could finish speaking, Pei Qi moved.

He didn't use any unnecessary fighting techniques; he simply took a precise half-step back, his body tracing an extremely subtle and accurate arc in the air.

The iconic "jump attack" pose of Minecraft players.

A long sword, entirely black and radiating a chilling, eerie light, instantly appeared in his hand.

As the sword was swung, the tip of the sword brought forth a fan-shaped sword aura with visible purple spatial cracks.

That's the visual representation of "Sweeping Blade III" in the real world.

"Pfft!"

Without any hesitation, the longsword sliced ​​through the demon's torso. The next second, the demon's body did not bleed or disintegrate as is traditionally expected.

Instead, the moment it touched the alloy sword, accompanied by a crisp sound like glass shattering on the ground, it disintegrated into countless white particles that shimmered with a faint light.

"The attack detection is still based on Minecraft logic as expected. With the sharpness of this sword and my heavy attack bonus, even a fully extended sword wouldn't last more than a few hits. Okay, this is very Minecraft."

Pei Qi sheathed his longsword and watched the particles rapidly dissipate and vanish into nothingness in the air, his expression unchanged.

With a casual wave of his hand, several oak blocks with thick wood grain suddenly appeared at the junction of the carriages, sealing the doors behind them tightly.

This method of isolation, which ignores physical structure and forcibly alters the terrain, gave him a sense of security in returning to the main world.

He didn't rush to the next carriage because he still had some things to take care of.

Pei Qi closed his eyes, carefully sensing the changes deep within his body.

A semi-transparent data frame appeared in the center of his vision. As he turned his gaze to the boy who had narrowly escaped death not far away, a small line of floating text appeared above the boy's head:

[Entity: Human/Neutral]

[Health Points: 20/20]

[Status: Deep Sleep (Caught in Blood Demon Art)]

"This is... an information display module?"

Pei Qi raised an eyebrow in surprise. "No, it's not just about displaying the environment. It seems my body has completely internalized these auxiliary functions."

He glanced at it in his mind. In the upper right corner of his vision, a delicate, semi-transparent circle marked with red and green dots was slowly rotating. That was the "mini-map".

In the image, the green dots representing friendly creatures are stationary, while the red dots representing hostile creatures are densely distributed in front of the train, especially at the front, where the red dots are large and flicker with an unstable light.

In addition, he discovered a more practical, but also more ridiculous, gadget.

"JEI (item inspection), minimap, information display... and even a Chinese localization module."

Pei Qi thoughtfully recalled what the ghost had said earlier.

When he first transmigrated, the demon spewed out Japanese roars that were clearly distorted by anger, but at that moment, Pei Qi heard his native language, which was extremely fluent and even had the quality of a system notification.

This is by no means a simple simultaneous interpretation, but rather a kind of low-level, rule-based localization patch.

"An interesting change. These tools, which used to exist only on the screen, have now become 'a part' of me?"

Pei Qi murmured his gratitude. He tried opening JEI's search bar. Although he couldn't directly retrieve items from it, he could clearly see how to craft various items.

"Let's see if it triggers more modules? If it includes 'Twilight Forest' or 'Industrial Age'..."

Pei Qi shook his head, stopping his wandering thoughts. "As for what happens next..."

He turned to look at the narrow door at the front of the carriage.

As a player familiar with the plot, he knew that the main characters on this train—Tanjiro, Nezuko, Zenitsu, Inosuke, and the Flame Pillar Kyojuro Rengoku, who was about to reach a turning point in his life—were currently trapped in the cage of a beautiful dream.

"Let's clean up these man-eating monsters on the train first."

Pei Qi picked up the heavy lower-realm alloy sword again and walked into the deepest darkness of the train.
