Honkai Impact 3rd: This is how Obito and Rin used it.

Chapter 10 Izumo Kamitsuki's Ambition, Practicing the Stitching Technique

Obito Uchiha remained unconcerned, muttering things like, "So what if a man has a scar?" and "People only look down on those who are clean-cut."

Rin Nohara: "What are you muttering about?"

Obito Uchiha quickly denied it: "No, I wasn't muttering anything."

"Lin, don't be angry. I'll take you home."

Nohara Rin said with a straight face, "No need."

"You should think about how to apologize to Xingyun. He gave you a fine kunai, and instead of giving him a scar, you gave him one."

Obito Uchiha protested, "I didn't accept it... Alright, alright, Rin, I was wrong."

Nohara Rin said, "You'd better really realize you're wrong."

"Also, Obito, although Nebula is a bit... a bit of a womanizer, he hasn't bothered me or done anything inappropriate."

"Stop causing him trouble. You're making things difficult for me."

"Rin, I..." Looking at Nohara Rin who turned to leave, Obito reached out his right hand to try to stop her, but in the end he just sighed dejectedly.

"Was I really wrong?"

"It's all Shenyue Xingyun's fault! You bastard, I'll make Lin see your true colors sooner or later."

……

"Lin." "Ah~"

After turning a few corners, the still somewhat rustic Nohara Rin unexpectedly bumped into the long-awaited Shingetsu Seiun.

Rin Nohara was startled: "Nebula, what are you doing here?"

Shingetsu Seiun touched Nohara Rin's shoulder briefly before separating.

"I’m waiting for you."

Rin Nohara: "Why are you waiting here? It's kind of scary."

Shingetsu Seiun said helplessly, "Rin, if we go any further, Obito will be following you the whole time. You know he won't be quiet if he sees you. And further on... your older brother is pretty fierce too."

Nohara Rin looked a little embarrassed: "What you said makes sense. Nebula, what are you waiting for me here for?"

"Of course, it's to thank you." Shen Yuexingyun raised her bandaged right hand and waved it in front of her eyes, saying sincerely, "Lin, if you hadn't helped, the old man in the infirmary definitely wouldn't have been able to handle it so well."

Nohara Rin: "You're welcome, you've already thanked me."

"Oh, right." Nohara Rin suddenly remembered something: "Nebula, the kunai you asked me to give you, Obito wouldn't accept it. I tried to persuade him, but..."

"Fine, if you don't want it, then forget it." Shenyue Xingyun looked disappointed.

Seeing this, Nohara Rin could understand her feelings. Yes, she had given a gift hoping to mend the relationship, only to have it slashed by a kunai. Anyone would be hurt in that situation.

"Lin, I don't need the kunai, you can keep it."

Nohara Rin was about to refuse when she heard this, but Kamitsuki Seiun continued, "Consider it a thank you for bandaging me in time."

Rin Nohara: "But this is too expensive, I can't..."

"Also, Lin, I've encountered some difficulties and hope you can help me," Shenyue Xingyun said. "If it's convenient for you."

...

Today, she had fewer dates than yesterday, only two, so Shingetsu Seiun got home earlier than usual.

Back home, Izumo Kamatsuki was practicing shuriken throwing in the yard, covered in sweat.

He paused for a moment when he saw Shingetsu Nebula carrying a bag.

"Why are you back so early today?"

Shenyue Xingyun: "We finished early today."

Looking at Shinzuki Seiun's hand, Izumo didn't focus on the bag she was carrying, but instead noticed the white gauze: "You're injured?"

"Yes, it was a minor scratch during practice, and a classmate has already taken care of it for me."

Shingetsu Seiun spoke casually, but Shingetsu Izumo easily deduced that it must have been done by a male classmate with a long-standing grudge.

The reason is simple: no female classmate would be so cruel to her brother.

"Classmate? Was it a female classmate who helped you?"

Shenyue Xingyun gave a thumbs up: "As expected of my brother, you guessed it perfectly."

Izumo Kamizuki pursed his lips, then looked at the bag in Seiun Kamizuki's hand.

"What are you carrying? Why is it still moving?"

Shenyue Xingyun showed the other person the contents of the bag, which turned out to be two black chickens.

"A black-boned chicken that's two and a half years old."

Izumo Kamitsu: "Why did you buy so many? Half a bird is enough for us if we're just eating them. You're not going to raise them to lay eggs, are you?"

Shenyue Xingyun: "Neither of us eats eggs, so why raise them? These are just for my use."

The moon is filled with doubt.

What else can chickens do besides eat?

Then, Izumo Shinzuki took out some sake from his house, opened the cap, held the sake in one hand, grabbed the chicken by the neck with the other, and poured the sake down the chicken's throat.

Before long, the chicken rolled its eyes.

Then, pluck the hairs.

After basically stripping them clean, he took out a small package from his personal ninja tool bag.

Gauze, portable scalpels, needles and thread, etc. are all available.

Using a knife, she cut a wound in the featherless black-boned chicken, placed it on the table, and Shen Yuexingyun took out a needle and thread to sew it up.

Shenyue Xingyun, who was observing from the side, raised an eyebrow.

"Are you practicing suturing?"

Shen Yue Xingyun didn't even look up: "That's right."

Izumo Kamitsu looked around curiously: "Why did you suddenly think of this?"

Shen Yue Xingyun's hands kept moving: "I'm about to graduate. Mastering a skill will give me an extra chance to save my life."

Izumo Kamitsu couldn't help but let out a 'hiss'.

graduate?

Bro, you've repeated a grade for two years, and you're still so confident?

He suppressed his inner grumbling, but upon hearing the sneer, Shenyue Xingyun still looked up: "What are you still doing here? Want me to practice on you?"

Izumo Kamitsu shut up and walked away, shaking his head as he went.

Big brother, oh big brother.

How can you make progress by cramming at the last minute?

The hopes of the Shingetsu clan rest on my shoulders; you can just relax and be the bottom of the pack. When I become a Jonin, I'll appoint you as the clan's vice-head!

Shenyue Xingyun, of course, had no idea that his little brother was already thinking about taking over the position of the Shenyue family's heir.

He devoted himself entirely to suturing the wounds of the featherless black-boned chicken.

After learning from Nohara Rin, the medical technique he can now most easily master and that has the greatest impact is external wound suturing.

In order to quickly master the basics of wound suturing, he borrowed tools from Nohara Rin and tried to learn the terminology in the shortest possible time.

One stitch, two stitches, three stitches...

While stitching up the wound, Shen Yuexingyun occasionally used up to 0.31 cal of chakra to nourish the chicken's wound. Although it was probably not very useful, what if it worked? He kept the chicken alive temporarily to test how effective the chakra nourishment was.

As he moved, the wounds on the chicken's body were slowly stitched together.

Ten minutes later, Shenyue Xingyun looked at her masterpiece with a serious expression.

Ok…

…It's a bit ugly.

No, it's just too ugly! It's like a child sewing a beanbag!

He casually flipped the chicken over, out of sight, out of mind. Shen Yue Xingyun picked up a scalpel and swiftly made another incision.

The chicken twitched, but thankfully didn't wake up.

The Shenyue Nebula continues to be stitched together.

I sew, I sew, I sew and sew.

After more than ten times, as the Divine Moon Nebula drew another line, the chicken... woke up.
