The blade flashed, as swift as lightning.
It was so fast that even Butterfly Ninja couldn't make out the details.
All she knew was that when the blade light disappeared.
The demon stood perfectly unscathed.
Realizing that he had not been hurt, the demon burst into laughter: "Haha, useless!"
"Ordinary weapons are of no use against me."
Butterfly Ninja couldn't help but chime in: "To kill a demon, you need a specially made Nichirin blade."
"Ordinary weapons can't break through a demon's defenses."
Facing both sides' remarks, Bai Chuan remained composed and calmly said: "Who said an ordinary weapon can't kill a demon?"
"Just because you can't, doesn't mean I can't."
"And besides, who gave you the illusion that my previous strike had no effect?"
As Bai Chuan finished speaking.
A streak of blood finally appeared on the demon's forehead.
"Ho... how..."
The demon finally realized what had happened.
Clear fear was etched in his eyes.
But no matter how incredible it seemed, it couldn't change his fate.
Accompanied by a final scream.
The demon split in two, right before everyone's eyes.
The cut was smooth and clean.
Even the blood was still flowing.
Bai Chuan's blade was so fast that the demon's bodily functions couldn't even react to being struck.
And Bai Chuan, without even glancing at the demon's corpse on the ground.
Simply turned his gaze towards the remaining demons.
"Tsk, how come they are all so weak?"
"Well, if they weren't weak, why would they need to gang up?"
"Whatever, it's just the beginning, I can accept them being weak."
Bai Chuan had not forgotten his plan.
His purpose this time was not to kill these demons.
Instead, he wanted to confine them, to use as test subjects.
To slowly transform himself into a demon using these demons.
Therefore, next.
Amidst the frightened gazes of the other demons.
Bai Chuan's blade appeared once more.
Just as swift, just as dazzling.
When everything disappeared.
The remaining demons lay screaming on the ground.
Their limbs had all been severed by Bai Chuan.
They had been ruthlessly turned into living stakes.
But what surprised the demons even more was.
Their wounds were being prevented from healing by a strange energy.
Yes, it was the power of Sun Breathing.
As Bai Chuan picked up these demons like garbage.
Preparing to take them away.
Butterfly Ninja finally couldn't bear it any longer.
She stood directly in front of Bai Chuan, her expression wary as she asked: "Who are you?"
"And what about the power you just used, is it also a Breathing Technique?"
Faced with Butterfly Ninja's questions.
Bai Chuan, for once, offered an explanation: "I'm just a passerby."
"As for my Breathing Technique, it's a variation of Sun Breathing."
"Alright, move aside, you're no match for me."
"I have no ill intentions towards you Demon Slayers, we're not enemies."
"As for these demons, rest assured, they won't be appearing before the world again."
Considering the nights he had spent chasing after updates, and the fact that the Demon Slayers all sacrificed themselves to kill demons, Bai Chuan harbored no ill will towards the Demon Slayer Corps.
He was even rather friendly.
Of course, he had no desire to befriend them either.
Perhaps later on, to obtain other Breathing Techniques.
He might make a trip to the Demon Slayer Corps.
But not now.
Right now, he had more important things to do.
After finishing his words, Bai Chuan, carrying these demons who had lost all ability to resist.
Disappeared before Butterfly Ninja in a few leaps.
At that moment, Butterfly Ninja finally regained her composure from the shock.
"He said Sun Breathing?!"
"But isn't Sun Breathing lost?"
"But if it isn't, what other Breathing Technique could there be that doesn't rely on a Nichirin blade to kill demons?"
"Regardless, this matter must be reported to the Master."
"What happens next depends on the Master's decision."
As a high-ranking member of the Demon Slayer Corps.
Butterfly Ninja was incredibly knowledgeable about Breathing Techniques.
Naturally, she knew about the legendary Sun Breathing.
And precisely because she knew, she understood.
This matter was too big.
Too important.
It might even lead to the realization of the Demon Slayer Corps' thousand-year dream.
And such a huge matter, naturally couldn't be kept secret.
She had to report it immediately.
Thinking about this, Butterfly Ninja didn't even bother collecting the demon corpses on the scene.
She rushed directly towards the Demon Slayer Corps Headquarters.
.....
On the other side.
Bai Chuan soon returned to his courtyard.
As soon as he landed, Kasumi Yuuhi pushed open the door and came out.
"Welcome back."
Seeing the demons in Bai Chuan's hands.
Kasumi Yuuhi didn't even bat an eyelid.
All her attention was on Bai Chuan.
She was the epitome of a dutiful wife.
It has to be said, when it comes to being a wife.
The Japanese truly possess a unique racial talent.
And Bai Chuan didn't think much of it.
He casually said: "It took a bit longer due to the journey, but everything went smoothly."
"Go back to your room, I'll take these things to the basement."
"I have some ideas I want to test out."
Only then did Kasumi Yuuhi notice the demons Bai Chuan was holding.
She furrowed her brows slightly.
Kasumi Yuuhi had a hunch.
These past few days, she wasn't just practicing Sun Breathing.
She also diligently learned about this world.
Naturally, she also knew what demons were.
And now, while Bai Chuan didn't explicitly say it.
But the intelligent Kasumi Yuuhi immediately figured it out.
Bai Chuan must be wanting to become a demon.
Although she didn't understand, Kasumi Yuuhi didn't need to understand.
She just needed to believe.
Just as Bai Chuan was about to head towards the basement with these demons who had lost their ability to resist.
Kasumi Yuuhi suddenly spoke up: "Do you really have to do this?"
Bai Chuan was taken aback.
Looking at Kasumi Yuuhi, he finally nodded.
Kasumi Yuuhi sighed, then said: "If you've already decided, then I have only one request."
"Take me with you!"
No matter what Bai Chuan intended to become.
No matter what he was thinking.
Kasumi Yuuhi didn't care.
She had only one thought.
Don't leave her behind.
Faced with Kasumi Yuuhi's request, Bai Chuan was a little amused.
"What are you thinking, I'm doing this because I'm confident."
"But when it comes to you, I'm not so sure."
The reason Bai Chuan dared to turn himself into a demon was that he believed in his own "omniscience."
But Kasumi Yuuhi didn't have the "omniscience" talent.
If she became a demon, she wouldn't be able to turn back.
That was not something Bai Chuan was willing to see happen.
