Demon Slayer: My breathing technique went awry after Nezuko pushed me down.

Nezuko pointed to the jagged branches around her, then to herself, her big pink eyes filled with "I hate it."

Shirakawa Yu understood. "Oh, there are too many branches, so it's uncomfortable to sit on, right?"

Nezuko nodded vigorously: "Mmm!"

"Then get off and walk by yourselves?" Shirakawa Yu suggested.

Nezuko thought for a moment, then with a "whoosh," she jumped off Shirakawa Hayao's neck.

When she landed, she was still in the shape of a small bean. Nezuko made a "hmm" sound and her body grew rapidly.

The pink kimono stretched out, and in the blink of an eye, she regained her graceful and elegant appearance as a young girl.

Moonlight shone on her delicate face, her pink eyes were clear and bright, and her natural youthful aura was overwhelming.

Zenitsu: (?ω?)

He was stunned.

My face flushed red, my heart started pounding uncontrollably, and countless pink bubbles instantly filled my mind.

So...so cute!!!

So beautiful!!!

This...this...is this what love at first sight feels like?!

Just as Zenitsu was immersed in the sudden "love"—

A strong hand suddenly landed on his shoulder.

"Boy."

A cold voice rang in his ears.

"Looking at your sister-in-law?"

Before he knew it, Shirakawa Yu had appeared behind him again.

He tilted his head slightly, a cold smile on his face, and his dark eyes gleamed with a golden light of "nuclear benevolence".

Zenitsu: Σ(°△°|||)︴

Sister-in-law... Sister-in-law! ? ?

He looked at Nezuko a couple more times in disbelief.

This caused Bai Chuanyu's smile to grow even colder, and his eyes to become increasingly dangerous. "Sister-in-law...is she pretty?"

Zenitsu trembled with fear at that look...

Help...help me...

Tanjiro~! ! !

Your senior brother's eyes are terrifying!!!

Chapter 54 The Purpose of Spider Mountain: To Save Little Mother~

Faced with Shirakawa Yu's terrifyingly "kind" gaze, Zenitsu shuddered and his mind went blank.

"Pfft!"

He once again performed a standard dogeza (a deep, prostration position), his forehead touching the ground, explaining with trembling hands.

"I'm so sorry, brother! I didn't know Tanjiro's sister was your wife! Please forgive me if I've been too forward!"

Bai Chuanyu: "..."

Nezuko: "...?"

The air was silent for two seconds.

"Pfft." Bai Chuanyu couldn't help but chuckle. "Never mind, just be more careful next time."

Then, looking at Zenitsu's back of the head, he casually reminded him, "The demons in this forest are spiders, and they're poisonous. Be careful not to get bitten."

"Huh?" Zenitsu was taken aback, looking up in confusion. "A spider?"

He was about to ask again when he discovered—

There was no one in front of him.

"Huh!?"

Zenitsu's eyes widened, and he suddenly stood up, looking around.

The dark, deep forest was deserted.

Shirakawa Yu and Nezuko, who were just standing in front of him, have now vanished without a trace.

"Big brother!? Tanjiro-senpai!? Shirakawa Yu!??"

Zenitsu's voice echoed in the silent forest, but there was no response.

He spun around and around, almost breaking his neck, but still couldn't see a single person.

Where did they go?!

Standing alone in the dark jungle, the night wind rustled through the treetops.

Zenitsu shuddered, goosebumps instantly spreading all over his body.

"No, no, no, it can't be..." His voice trembled with tears. "You've abandoned me again!? At least... at least take me with you!!!"

100 meters away.

Shirakawa Yu was holding Nezuko's hand, walking leisurely along the forest path.

He turned and glanced into the distance. Although he couldn't see clearly through the trees, he could vaguely hear Zenitsu's tearful cries.

He shook his head, but didn't stop.

He wasn't angry because Zenitsu looked like he was in love.

The reason for leaving alone is the same as when he trained Tanjiro.

Zenitsu will also be considered an important fighting force in the future.

He will not deprive you of the necessary experience.

Moreover, he had already noticed that Zenitsu's breathing was strong and even, clearly indicating that he was already approaching the level of "normal breathing".

It must have been Tanjiro who taught him during those two months of recuperation.

In addition, I reminded myself to be careful of spiders.

If that's the case, even Zenitsu wouldn't have survived...

Well... there's not much more to say.

Looking around again, Shirakawa Yu's eyes gradually brightened, and the shape of his pupils changed accordingly.

A moment later, a pair of eerie golden arrow-shaped pupils took shape in his eye sockets.

And in his view—

The messy footprints on the ground suddenly became "clear".

The footprints, all the same size and depth, were automatically arranged neatly, allowing him to clearly see the activity trajectories of each person.

The most striking thing was the footprint of Tanjiro that he had deliberately examined.

The familiar footprints were accompanied by a striking flame and even arrows pointing the way.

"These eyes are so convenient," Shirakawa Yu couldn't help but exclaim.

In the past two months, apart from his normal cultivation and accompanying Tamayo in her experiments, he has spent most of his time figuring out the Blood Demon Art "Crimson Arrow".

According to his tests, the pulling force of each Crimson Arrow is approximately half of its own strength.

This intensity is not considered very high.

If used against someone of similar strength, the effect would obviously be relatively small.

This is why the Arrow Demon always likes to lift people into the air before attacking.

Because it is difficult for someone who has been lifted into the air to resist the pull of the arrow.

In this way, even with only half the strength of a person, one can knead at will.

Of course, there are many ways to use the Crimson Arrow.

Although a single arrow only has the strength of half a person, it can be stacked.

One and a half people, two combined are naturally Bai Chuanyu's full strength, and so on for three or four.

Shirakawa Hana tested it on Yushiro, and the cumulative effect only gradually weakened after at least five levels, which is two and a half people's power.

Bai Chuanyu can use a total of thirty-six Crimson Arrows!

If he were to actually riddle the enemy with holes, he could simply drag them and slam them into the ground to create a fresh pile of mud.

The only drawback is that Crimson Arrow can only be used within sight.

It will disappear immediately once it is out of sight.

I followed the footprints for three minutes.

"Hey! Ha!"

The sounds of fighting came from afar and reached Shirakawa Yu's ears.

The source of the sound was along the path Tanjiro was walking.

Shirakawa Yu quickened his pace.

But when he followed the sound to a small clearing with sparse vegetation, he did not see Tanjiro.

Instead, it was an unremarkable figure from afar, and even less distinctive upon closer inspection, fighting against several slow-moving team members.

The team members had vacant eyes and stiff movements like marionettes, with fine spider silk wrapped around their bodies.

Meanwhile, the seemingly unremarkable person was frantically dodging attacks while trying to cut the threads binding his companion with a knife.

"Ah~~~~~" Shirakawa Yu's eyes lit up.
