My avatar is the heroine

No matter how you look at it, it's not right not to be a little wary of someone who's a pillar-level expert.

In contrast, Su Lin's true form calmly asked, "What kind of information do you need?"

"I'm worried about whether you can provide the correct information. Why don't you tell me what kind of person I am?" She smiled gently, her voice soft and pleasant, giving people a very friendly feeling.

Su Lin, who has read the comics, doesn't know too much about her, okay?

"Shinobu Kocho, the Insect Pillar, is the most unique of the nine Pillars of the Demon Slayer Corps. She has little arm strength and a petite and slender build, making it impossible for her to decapitate demons. However, she is incredibly fast and skilled in medicine and toxicology, able to easily kill powerful demons with poison. Your height is 151 cm, your weight is 37 kg, and your age is 18."

Shinobu's expression changed slightly, but she immediately regained her smile: "Oh, are you sure that's really true? Just saying it casually won't do any good."

"Although you've always appeared very gentle, that's not your true nature. Deep down, you harbor a repressed hatred for demons. But because of your deceased sister..."

"enough!"

A rare chill swept through the air, and the gentle girl, unable to restrain herself because of her sister's name, swung her rapier.

Clang——

With an even more elusive speed, Kurohime's Yatsufusa slashed at the opponent's blade in an instant, the powerful force sending the girl staggering back two steps. The trembling blade still retained an unimaginable amount of power.

"So fast!" Shinobu Kocho suddenly shuddered, feeling a chill run down her spine.

In that instant, Kuroko had already sheathed her sword and stood silently to the side.

Looking at the petite girl in the black sailor uniform again, Shinobu Kocho felt a deep sense of pressure.

She hadn't even seen how her attack was blocked. It could only be said that this girl, younger than her, at most ten years old, was an unimaginably strong individual.

"Don't do anything in the store," Su Lin said casually.

"I'm sorry, I lost my composure." Shinobu Kocho immediately bowed.

A wicked smile appeared on her dark-eyed face. Perhaps it was because this girl's signature expression was too mysterious that she always gave people a sense of ease and control!

Shinobu Kocho was unable to calm down.

Black hair and black eyes, avant-garde clothing that puts this era to shame, stunning beauty and a slender waist, coupled with such strength... She took a deep breath. Originally, she only wanted to casually test this rumored shop in the city, but she didn't expect to encounter such a big surprise.

"I will quote a price based on the specific information you require."

Su Lin's words stirred her thoughts. No matter who the person in front of her was, she saw hope for revenge in him.

"I want to know, who killed my sister?" Her voice trembled.

"You know the answer to this question, right? Are you still testing me?" Su Lin said with a smile.

Shinobu's heart sank. At this moment, she was finally certain that the young man in front of her knew everything about her.

But could there be an omniscient person in the world? Su Lin even gave her an unreal feeling.

"Then, how can I avenge my sister?" she continued.

Su Lin pondered for a moment, then said calmly, "Your sister probably wanted to tell you before she died that with your small body, you would never be able to cut off the enemy's head, let alone the enemy being the Upper Moon Two of the Twelve Demon Moons—Doma. In my opinion, she was right. Even if you found the enemy, you would only be throwing your life away in vain."

Shinobu Kocho: “…”

In the manga, Shinobu Kocho did indeed die, just like her sister. As a transmigrator, knowing some of the plot details, why would Su Lin let her die again?

Not to mention, he actually quite liked this girl.

So he continued:

"Don't be discouraged. In theory, I accept any deal. If you want to kill Doma on your own, then as long as you hand over a breathing technique, I can lend you a hand in some future possibility. You decide."

It has to be said that Su Lin was acting like a charlatan at this moment. Kocho Shinobu, who was determined to avenge her sister, could not resist the temptation and made up her mind in a moment of impulsiveness: "I am willing to hand over my breathing technique."

"Insect Breathing? Yes..." Su Lin nodded gently.

Chapter 124 Rapid Improvement

Breathing techniques are a major feature of the Demon Slayer world, which can greatly enhance the user's physical fitness and combat power. The five basic breathing techniques of today, namely Water Breathing, Flame Breathing, Rock Breathing, Lightning Breathing, and Wind Breathing, all evolved from the original Sun Breathing.

In addition to the five breathing techniques, many unique breathing techniques have been derived, such as the Beast Breathing of a certain "pig" or the Insect Breathing of the person in front of me, Shinobu Kocho.

While the difficulty of learning different breathing techniques varies, not everyone can master them. Not to mention Insect Breathing, which is derived from Flower Breathing and specifically tailored to Shinobu Kocho's individual circumstances, it is simply not suitable for a man of Su Lin's physique.

Moreover, the killing moves of Insect Breathing are all venomous stings, and its movements are quite feminine, so it is not very effective against people who cannot use poison.

"Something is better than nothing. No matter what, breathing techniques can always be used as a killer move in critical moments."

After listening to the other party's description, Su Lin immediately had his clone help analyze it, and then signaled Kuroto to lift up Hachifusa and give it a try.

"The breath of insects, the dance of butterflies, teasing."

She leaped lightly, her black eyes flashing with a sharp blade, moving with unimaginable speed. A mechanical doll in the hall was pierced through by astonishing force, and she instantly appeared behind it.

"That's a very good move." Su Lin nodded.

Shinobu Kocho: “…”

Her silence spoke of her inner shock. No matter how simple the breathing technique, it's impossible to master it after just one listen, right? This beautiful young woman is simply too terrifying.

"Four moves, right? Then, according to the deal, I will personally come to help you during the final battle in the Infinite City."

"Infinite Castle...the final battle?"

"That's Muzan's lair, a vast, interconnected space. If things had gone according to plan, you would likely have ended up with your body filled with toxins and being devoured by Doma, which would have been pointless."

After Su Lin finished speaking, he remained silent.

After pondering for a while, Shinobu Kocho suddenly bowed and said goodbye, "Thank you, senpai."

The way they were addressing each other with honorifics made Su Lin's eyelids twitch; she felt they were going a bit overboard.

However, this is for the best, as it facilitates contact with the Demon Slayer Corps and allows them to participate in the future operation to kill Muzan. Otherwise, given that guy's vigilance, finding out his location would be virtually impossible.

After seeing Shinobu off, Yukino and Kurome began to diligently practice Insect Breathing.

Don't be fooled by the move she just used; she didn't truly master it at all. Kurohime merely temporarily switched to her battle form and simulated the move.

In normal circumstances, her physical abilities are actually not as good as Yukino's; she only appears so powerful because of her assassination skills.

While Yukino was training, Su Lin picked up his hammer again, preparing to forge the next useful weapon.

Ding!

The moment the hammer struck, two lines of small subtitles appeared before my eyes.

[Sharpness +1]

[The main body obtains a lucky card: Strength +1]

The gold card, overflowing with shimmering light, slowly floated up, and an indescribable warm current flowed into its body.

"It's gotten lighter."

As his strength increased, the hammer, which had been somewhat difficult to lift, suddenly became much lighter. He was in a great mood and increased the speed of his hammering.

Nightingales don't have much time, so they don't usually try to increase their magical effects.

But in the end, he still managed to forge a weapon with [Demon Slayer +2].

Ding!

The final blow.

[Weight - 1]

[Gained +1 Demon-Slaying Stone.]

[Demon-Slaying Stone +1: Melt this stone into liquid, pour it onto the weapon, and strike it 88 times. Demon-Slaying attribute increases by 1 point.]

A translucent, orange-red ellipsoidal crystal, about the size of a fist, floated in mid-air.

Su Lin was somewhat surprised to grab it, and after touching it, he felt the unique weight of a precious gemstone.

He glanced at the weapon in Kurohime's hand and asked in a low voice, "Can this stone be used on Yatsufusa? Will there be any side effects?"

[Safe to use.]

The system replied.

"That's really nice."

Without the ability to counter oni, it's impossible to kill an oni. Even someone as powerful as Yatsufusa can at most cut off an oni's head, but cannot take its life.

But now that we have this stone, things are different.

Kuroko handed over the Eighth Chamber to Su Lin.

The moment I touched it, an unimaginable feeling of palpitation washed over me, but it was gone in a flash...

"This must be the backlash from the Imperial Arms. Luckily, Kurome and I are essentially the same person, or we would have died on the spot."

The knife was thrown into the melting pool. After 30 minutes, the Demon Stone melted into liquid. Su Lin scooped it up and slowly poured it onto the blade. Then he picked up a hammer and began to rhythmically strike it.

Ten minutes later, after the reservation was completed, the eight rooms began to hiss and emit white smoke from the water.

Once cooled and retrieved from the water, its appearance seems no different from before it was crafted. However, if you bring up the panel, you can see a row of values: [Sharpness +9, Slashing +1, Demon Resistance +1].

These are all attributes acquired during the initial forging process.

"That's good. If we get similar items in the future, we can give them to Hachifusa to use."

Of course, he wouldn't forget to forge a sword for both himself and Yukino.

With the telekinetic power that Rikka Takanashi conjures, she can even control hundreds of Oni-slaying weapons. Considering that the more weapons she has, the lower the damage per weapon becomes, she thinks it's best to keep the number under 10.

By the next day, Su Lin had forged six knives.

"We're running out of ingredients, let Yukino go buy some."

I should make time to train.

His current attributes are as follows:

Strength: 5, Spirit: 3, Constitution: 4, Resistance: 1

[Special Ability: Double Damage +1]

From an attribute perspective, resistance is the hardest to increase.

The special ability is a passive attribute gained after obtaining a very rare card, which can deal a second instance of damage after hitting the target.

The current +1 value is just too low, and it's unclear how strong the effect will be.

While forging his weapon, he sparred with Kurohime. Gradually, his combat skills improved rapidly, and with a bit of luck, he could even single-handedly kill the most basic demons.

This growth brought him genuine joy.

……

That night, Su Lin made a decision to leave the town after midnight and head to the surrounding mountain villages to search for ghosts.

Before leaving, he opened the wardrobe, stared at the empty clothes, remained silent for a while, then summoned all his clones, including X, and began to take off his clothes.

Yukino's plaid sailor-style school uniform.

Rikka, like Kurome, is wearing a sailor uniform, and her clothes have a faint girlish scent.

Nightingale's long dress exudes a sense of holiness, like a princess's attire, but unfortunately, due to her figure and temperament, it is only suitable for her to wear.

Chapter 125 Strange Ghost

Qiong Mei wore white over-the-knee socks and a spaghetti strap dress that revealed her rounded shoulders. Below the short skirt was a white, plump body, with a small, suggestive patch of "absolute territory" between her and the stockings, pure white and flawless.

"Your outfits lately have been getting more and more alluring."

Qiong Mei sighed, sat on the bed, gently placed her legs on Su Lin's thighs, and then took off her stockings.

As for X... well, the shorts and jacket are pretty good; they wouldn't look out of place on the real person. There's a hole in the hat because of the ahoge (antenna-like hair sticking up), but it's not a big deal.

After taking off her coat, "Artoria's" large breasts made Su Lin drool.

"This is what a chest looks like! Yukino's is practically a washboard... I can't even feel anything when I touch it." The main body patted Yukino's sensitive chest, recalling Yaoyorozu's mocking comment about her flat chest, and couldn't help but laugh and cry.

Even so, he still likes Yukino.

"Take off your bra as well, just in case it tears and you're left with nothing to wear."

Soon the bed was covered with girls' clothes, especially stockings and panties, which were still warm and made people's imaginations run wild.

Su Lin picked up a bra and sniffed it, confirming that it was the scent of Rikka.

"Rikka has only just graduated from junior high school. Am I being too weird?"

He shook his head, arranged the clothes neatly, canceled the clone, and waited until after midnight before summoning Black Eyes and leaving the house.
