Finally, El had arrived near Mugen's train repair facility. There, El saw Mugen trains under repair, even he also felt traces of demonic presence just from outside the building area.
"Hmm, very Deja Vu. Really pisses me off." El muttered while walking to the building.
Suddenly, El was approached by an adult male. From his physical features, El vaguely recognized the man. In the anime Kimetsu no Yaiba, it was clear that the man was a chief engineer.
Feeling curious, the man started a conversation. "Excuse me, who are you and what do you need?"
"May I ask where the nearest town is? And what is this place?" El asked with a carefully constructed story.
"Ah, is that so? You're lost." the man said while scratching his head even though it wasn't itchy.
Soon, the man stopped scratching his head. "Are you from out of town?"
"Hn." El nodded his head. "About that, can I know what this building is? Why are there so many workers repairing the train?"
The man turned his back and explained, "This building is a carriage repair facility."
Then the old man pointed at the carriage under repair. "That is the Mugen Train. But it's being repaired and will be back in service tomorrow night."
Suddenly, the sound of shouting was heard, El entered the building, immediately approaching the origin of the sound. There, the workers and even the chief engineer were also very surprised to find this.
"Who are you?"
"Hey, let that guy go!"
"Quick, call the police!"
All the people were a bit rowdy to find a figure that looked like a bald middle-aged man, a muscular body and very pale skin. His entire body was covered in dark blue tattoos, stretching across various faces.
The figure's irises were lime green, black sclera and vertical slits for pupils, and he had sharp pointed nails that were dark blue in color about to grip a worker.
The middle-aged man smiled like a maniac who had found something very interesting. It made several fangs stand out in his mouth.
He was also wearing a blue sleeveless shirt and black leggings complete with tabi socks, and a pair of zōri with blue laces.
"H-help me, I don't want to die!" the poor young man said with tears in his eyes.
With a smile of madness using the poor young man, a middle-aged man said, "Don't anyone come near or call the police otherwise this young man will die!"
"Slasher, let him go." El said in a cold tone of voice.
The demon looked at El, looked her up and down, and found that she was carrying a sword. "Hoo, you're not an ordinary person apparently."
"Even if I am, so what? Just let go of that young man. I'm sure you won't eat him." El said in a cold tone of voice.
"Hahaha, you're an interesting person!" The demon burst out laughing at El's words.
Seeing that it was an opportunity, El immediately moved quickly, without using any Breathing Style, cutting off Slasher's hand.
Slash! Slash!
A flash of cold light cut through both of the demon's hands that were hugging the poor young man from behind was created.
This freed the poor young man from Slasher's grip.
"What?" said Slasher in surprise.
Slasher was so shocked by El's quick and sudden movement. In fact, all the workers were also surprised because El suddenly appeared right in front of the demon and cut off his hand.
Because El moved so quickly, it indirectly made it a hard slap on Slasher's face. Slasher's expression that was full of madness metamorphosed into one full of annoyance.
"Bastard!" Slasher said with the fury of an erupting volcano.
Slasher instantly activated his Blood Demon Arts. The dark blue tattoos all over his body lit up and glowed blue. As soon as his Blood Demon Arts activated, Slasher ran around and jumped up and down around El.
Because the eye of insight was constantly active. With ease, El could see Slasher even though it was moving very fast. El deliberately didn't take action now, directly slashing Slasher's neck because the train repair facility building was still crowded.
"It will be troublesome to explain to them about what just happened." El muttered in a low voice.
El glanced around, finding the expressions of the repair facility workers to be extremely confused. Fortunately, the poor young man survived without any serious injuries, only a slight tear in the skin of the chest.
Satisfied with that, Slasher appeared outside the gate of the repair facility building. Slasher smiled dismissively, "Fool, try chasing me, if you can!"
After saying that, Slasher activated his Blood Demon Art again. The tattoos all over Slasher's body lit up. With that, Slasher's moving speed increased significantly.
Then Slasher instantly left as fast as the wind. The dark blue tattoos lit up all over his body, making flashes of light as he moved.
Without saying anything, El's figure suddenly distorted and disappeared like a blurry image on a damaged photograph. This left the people at the train repair facility in shock.
"What exactly is going on?"
"What the hell are they?"
"Are they human?"
Although many questions arose that piqued their curiosity, they couldn't ask El or Slasher because they had left.
After all, the workers also still had work to complete according to schedule, namely repairing the Mugen Train.
The poor young man was told to rest by the head of the repair facility, in the hope of recovering from the shock of the sudden incident he experienced.
In addition, the young man also wrapped his wound with a bandage.
The head of the repair facility sighed. "This world really is vast!"
***
"Hahaha, that stupid human definitely won't catch up!" said Slasher with a big smile on his face.
On the dark railroad tracks, Slasher moved like a hurricane. Flashes of bright dark blue light were left behind every time Slasher moved.
Slasher was so proud of his great moving speed, it was incomparable to anything. An arrogant facial expression with a smile like a crazy psychopath continued to expand with every step.
Unbeknownst to Slasher, at a distance not too far away and steadily approaching him at a speed like a flash of lightning, El continued to narrow the gap quickly.
"Hmm, this is strange..." muttered Slasher, as soon as Slasher looked back, he found the flashes of light continuing to approach rapidly.
"Geh!" Cold sweat ran down his face slightly. Quickly, Slasher immediately increased the movement speed to the maximum.
El grinned. "Heeh, so Slasher is further increasing his Blood Demon Art output to move faster?"
Feeling a little challenged, El increased the output of the blood vessel muscles inside him consecutively, eight times. "Hekireki Issen: Rokuren."
Jedar!
With the loud booming sound of lightning striking, El's movement continued to increase significantly. The air around El continued to vibrate and hiss frighteningly.
Until finally, El actually managed to catch up. El drew Nichirin, slashing Slasher's neck beautifully.
"Argh!" Slasher cried out in pain as his neck was slashed. His facial expression of pain was mixed with confusion
"Kaze no kokyū." However, not stopping there, El continued to slash.
"San no kata: Seiran Fūju." El unleashed a vortex of slashes around their bodies and brutally sliced through the environment to create a whirlwind of stormy wind.
Slash! Slash! Slash!
This time, El changed his Breathing Style and targeted the Slasher's body. The slash seemed to shred the Slasher's body with a wind knife. The scene was similar to meat in a grinding machine.
Until finally, Slasher's body was completely destroyed like minced meat.
Luckily, the accuracy of El's slash had improved more than before.
Otherwise, the railroad tracks would have also been shredded by El's brutal slash.
El sighed and sheathed Nichirin again. "The Wind Breathing Style is indeed brutal." El said, looking at the aftermath around his.
"Fortunately, I've been practicing with more emphasis on the accuracy of the Wind Breathing Style. But more importantly, I have an insightful eye ability."
"Thus, the accuracy of my slashes has improved greatly. This insight ability suits me very well." El smiled with satisfaction.
